Before potatoes and rice, there were pulses

Although I spent most of my career working on potatoes and rice, my first interest was pulse crops or grain legumes. In fact the first pulse that I studied was the lentil (Lens culinaris Medik.) when I was an MSc student at the University of Birmingham from 1970-1971.

So why the interest in pulses?

It was surely the influence of one of my mentors, Dr Joe Smartt (right) at the University of Southampton where I was awarded my BSc in Environmental Botany and Geography in 1970. A geneticist who had studied groundnuts in Africa and at Southampton was working on Phaseolus beans, Joe taught a second year genetics course, and two in the third or final year, on plant breeding and plant speciation.

He published two seminal texts on pulses in 1976 and 1990.

It was Joe who ignited my interest in plant genetic resources, and encouraged me to apply for a place on the one year MSc course at Birmingham on Conservation and Utilization of Plant Genetic Resources (CUPGR). The course had been launched by the head of the Department of Botany, potato expert, and genetic resources pioneer, Professor Jack Hawkes, with the first intake of students commencing their studies in September 1969. I landed in Birmingham a year later.

My three year undergraduate course at Southampton was a stroll in the park compared to the intensity of that one year MSc course. We had eight months of lectures and practical classes, followed by written examinations at the end of May. Each student also had to complete a piece of independent but supervised research, and present a dissertation for examination in September. In order to take full advantage of the summer months, planning and some initial research began much earlier. First of all for most of us, we had to decide on a topic that was feasible and doable in the allotted time, and assemble the necessary seed samples ready for planting at the most appropriate date.

Almost immediately I decided on three points. First, I wanted to run a project with a taxonomy/natural variation theme. Second, I wanted—if feasible—to work on a pulse species. And finally (which I decided quite quickly after arriving in Birmingham) I wanted to work with Dr Trevor Williams (right) who delivered a brilliant series of lectures on variation in natural populations, among others.

Trevor and I thumbed our way through the Leguminosae (now Fabaceae) section of Flora Europaea, until we came upon the entry for Lens, and the topic for my project leapt off the page: Lens culinaris Medik. Lentil. Origin unknown.

My project had two components:

An analysis of variation in the then five species of lentil (one cultivated, the others wild species; the taxonomy has changed subsequently) from herbarium specimens borrowed from several herbaria in Europe. I also spent a week in the Herbarium at Kew Gardens in London taking measurements from their complete set of lentil specimens.
A study of variation in Lens culinaris from living plants, with seeds obtained from Russia (the Vavilov Institute in St Petersburg), from the (then) East German genebank in Gatersleben, and from the agricultural research institute in Madrid.

With the guidance of another member of the Botany department staff, Dr Herb Kordan, I made chromosome preparations and counts of all the Lens culinaris samples I’d obtained, confirming they were all diploid with 2n=2x=14 chromosomes. In the process, we developed a simple but effective technique for making chromosome squash preparations, and this led to my first ever publication in 1972. Just click on the title below (and others in this post) to read the full text.

In September 1971, I submitted my dissertation, Studies in the genus Lens Miller with special reference to Lens culinaris Medik. (which was examined by Professor Norman Simmonds who was the course External Examiner), and the degree was awarded.

I proposed that the wild progenitor of the cultivated lentil was Lens orientalis (Boiss.) Hand.-Mazz., a conclusion reached independently by Israeli botanist Daniel Zohary in a paper published the following year.

In 1971-1972, Carmen Kilner (née Sánchez) continued with the lentil studies at Birmingham, leading to a publication in SABRAO Journal in 1974. Our paper added further evidence to confirm the status of Lens orientalis.

When I began my lentil project, I had ideas to extend it to a PhD were the funding available. However, in February 1971 Jack Hawkes had just returned from a potato collecting mission to Bolivia, and told me about an exciting opportunity to spend a year in Peru at the newly-founded International Potato Center (CIP), from September that same year. My departure to Peru was delayed until January 1973, so I began a PhD on potatoes with Jack in the meantime. And with that move to potatoes, I assumed that any future work with pulses was more or less ruled out. However, from April 1981 I was appointed Lecturer in Plant Biology at Birmingham, and needed to develop a number of research areas. Would pulses figure in those plans?

While I wanted to continue projects on potatoes at Birmingham, I also decided to return partially to my first interest: pulses. And while I never had major grants in this area, I did supervise graduate students for MSc and PhD degrees who worked on a range of grain and forage legume/pulse species. Here I highlight the work of three students. There may have been more who worked on pulses, but after four decades I can’t remember those details.

Almost immediately after returning to Birmingham, I discovered (by looking through Flora Europaea once again) that the origin of the grasspea, Lathyrus sativus, was unknown. The grasspea is a distant relative of the ornamental sweetpea, Lathyrus odoratus, one of my favorite flowers since I was a small boy. My grandfather used to grow a multitude of sweetpeas in his cottage garden in Derbyshire. Anyway, I set about assembling a large collection of seed samples (or accessions) of grasspea and wild Lathyrus species from agricultural centers and botanic gardens worldwide.

The academic year September 1981-September 1982 was my first full year at Birmingham. Among the CUPGR intake was a Malaysian student, Abdul bin Ghani Yunus (right), who asked me to supervise his MSc research project. I persuaded him to tackle a study of variation in the grasspea and its wild relatives, much along the lines I had approached lentil a decade earlier.

We published this paper in 1984, and I guess it heralded what would become, a several decades later, an international collaborative effort to improve the grasspea and make it safer for human consumption.

Ghani returned to Malaysia, and I didn’t hear from him for several years. Then, in 1987, he contacted me to say he’d secured a Malaysian government grant to study for his PhD and would like to return to Birmingham. But to work on a tropical species, the name of which I cannot remember.

I persuaded him that would not really be feasible in Birmingham as we didn’t have the glasshouse space available, and it would be hit or miss whether we would be able to grow it successfully. I suggested it would be better to carry on his Lathyrus work from where he left off. And that’s what he did, successfully submitting his thesis in 1990 from which these papers were published.

Among the 1986 CUPGR intake was a student from Mexico, José Andrade-Aguilar (right) who was keen to attempt a pre-breeding study in Phaseolus beans, specifically trying to cross the tepary bean, Phaseolus acutifolius A. Gray with the common bean, Phaseolus vulgaris L.

José published two papers from his dissertation.

This next paper (for which I no longer have a copy) described how pollinations in Phaseolus species could be made more successful.

Then, in 1987, a student from Spain, Javier Francisco-Ortega (right, actually from Tenerife in the Canary Islands) joined the course, and he and I worked closely on his MSc and PhD projects until I left Birmingham to join IRRI in the Philippines in July 1991.

Javier was an extraordinary student: hard-working, focused, and very productive. After completing his PhD in 1992, he took two postdoctoral fellowships in the USA (at Ohio State University and the University of Texas at Austin) before joining the faculty of the Department of Biological Sciences at Florida International University in 1999, where he has been Professor in Plant Molecular Systematics since 2012.

For his 1988 MSc dissertation, Javier studied the variation in Lathyrus pratensis L., using multivariate analysis, and publishing this paper some years later.

Then, having successfully completed his MSc, and being awarded a second Spanish government scholarship, Javier began a PhD project to study the ecogeographical variation in an endemic forage legume from the Canary Islands, Chamaecytisus proliferus (L. fil.) Link., known locally as tagasaste or escobón, depending whether it is cultivated or a purely wild type.

With a special grant from the International Board for Plant Genetic Resources (IBPGR, now Bioversity International) in Rome, Javier returned to the Canary Islands in the summer of 1989 to survey populations and collect seeds from as many provenances as possible across all the islands, and I joined him there for several weeks.

Collecting escobón (Chamaecytisus proliferus) in Tenerife in 1989

After I left Birmingham, my colleague Professor Brian Ford-Lloyd took over supervision of Javier’s research, seeing it through to completion in 1992.

Together we published these papers from his research on tagasaste and escobón.

Once I was in the Philippines, I forgot completely about legume species, apart from contributing to any of the papers that were published after I’d left Birmingham.

One aspect that is particularly gratifying however is seeing the work Ghani Yunus and I did on Lathyrus still being cited in the literature as efforts are scaled up to improve grasspea lines.

Potatoes have no special chemistry to induce romance . . . but they brought us together

Saturday 13 October 1973, 11:30 am
Lima, Peru

Fifty years ago today, Steph and I were married at the town hall (municipalidad) in the Miraflores district of Lima, where we had an apartment on Avenida José Larco. Steph had turned 24 just five days earlier; it would be my 25th in the middle of November.

Municipalidad de Miraflores, Lima

It was a brief ceremony, lasting 15 minutes at most, and a quiet affair. Just Steph and me, and our two witnesses, John and Marian Vessey. And the mayor (or other official) of course.

John, a plant pathologist working on bacterial diseases of potato, was a colleague of ours at the International Potato Center (CIP) in Lima, who had joined the center a few months before I arrived in Lima in January 1973.

The newly-weds.

It’s by chance, I suppose, that Steph and I got together in the first place. We met at the University of Birmingham, where we studied for our MSc degrees in Conservation and Utilization of Plant Genetic Resources.

Steph arrived in Birmingham in September 1971, just after I had finished the one-year course. I was expecting imminently to head off to Peru where I had been offered a position at CIP to help curate the large collection of native potato varieties in the CIP genebank. So, had I flown off to South America then, our paths would have hardly crossed.

But fate stepped in I guess.

My departure to Peru was delayed until January 1973. So I registered for a PhD with renowned potato expert Professor Jack Hawkes (right, head of the Department of Botany and architect of the MSc course), and began my research in Birmingham while CIP’s Director General, Richard Sawyer, negotiated a financial package from the British government to support the center’s research for development agenda, and my work there in particular.

It must have been early summer 1972 that Steph and I first got together. Having completed the MSc written exams in May, Steph began a research project on reproductive strategies in three legume species, directed by Dr Trevor Williams (who had supervised my project a year earlier on lentils). And she completed the course in September.

By then, she had successfully applied for a scientific officer position at the Scottish Plant Breeding Station in Edinburgh (SPBS, now part—after several interim phases—of the James Hutton Institute in Dundee), as Assistant Curator of the Commonwealth Potato Collection. But that position wasn’t due to start until November.

In early November I took delivery of a left-hand-drive Volkswagen for shipment to Peru. On a rather dismal Birmingham morning, we loaded up the VW with Steph’s belongings and headed north to Edinburgh. She returned to Birmingham in mid-December for her graduation.

Then, just after Christmas 1972, we met up in a London for a couple of days before I was due to fly out to Lima.

At that time we could not make any firm commitments although we knew that—given the opportunity—we wanted to be together.

Again fate stepped in. On 4 January 1973, Jack Hawkes and I flew to Lima. Jack had been asked to organize a planning conference to guide CIP’s program to collect and conserve native Andean potato varieties and their wild relatives.

Potato varieties from the Andes of Peru.

While I stayed in a small hotel (the Pensión Beech, in the San Isidro district) until I could find an apartment to rent, Jack stayed with Richard Sawyer and his wife Norma. And it was over dinner one evening that Jack mentioned to Richard that I had a ‘significant other’ in the UK, also working on potato genetic resources, and was there a possibility of finding a position at CIP for her. Richard mulled the idea over, and quickly reached a decision: he offered Steph a position in the Breeding and Genetics Department to work with the germplasm collection.

With that, Steph resigned from the SPBS and made plans to move to Lima in July, with us planning to get married later on in the year.

A couple of weeks after I arrived in Peru, I found an apartment in Miraflores at 156 Los Pinos (how that whole area has changed in the intervening 50 years), and that’s where Steph joined me.

A few weeks later we found a larger apartment, nearby at 730 Avda. Larco, apartment 1003. Very interesting during earthquakes!

Around mid-August 1973 we began the paperwork (all those tramites!) to marry in Peru. Not as simple as you might think, but on reflection perhaps not as difficult as we anticipated.

While we were allowed to post marriage banns in the British Embassy, we had to announce our intention to marry in the official Peruvian government gazette, El Peruano, and one of the principal daily broadsheets (El Comercio if memory serves me right), and have the police visit us at our apartment to verify our address. I think we also had to have blood tests as well. This all took time, but everything was eventually in place for us to set the wedding date: 13 October.

Some friends wanted to give us a big wedding, but Steph said she just wanted an intimate, quiet day. So that’s what we organized.

In the week leading up to our wedding, we had to present all the notarised documents at the municipality. After the ceremony, we signed the registry, hand-written in enormous volumes (or tomos). There was a bank of clerical staff, all with their Parker fountain pens, inscribing the details of each wedding in their respective tomo. A week later we collected our Constancia de Matrimonio (with some errors) which detailed in which tomo (No. 83, page 706) our marriage had been recorded, as well as photocopies (now sadly faded) of the actual page.

My work, collecting potatoes, took me all over the Andes; not so much for Steph who only made visits every other week or so to CIP’s highland experiment station (at over 3000 masl) in Huancayo east of Lima, and a six hour drive away.

However, Steph and I explored Peru together as much as we could, taking our VW on several long trips, to the north and central Andes, and south to Lake Titicaca. We also delayed our honeymoon until December 1973, flying to Cusco for a few days, and spending one night at Machu Picchu.

In May 1975, we returned to the UK for seven months for me to complete my PhD, returning to Lima just before New Year.

Then, in April 1976, we moved to Costa Rica where I worked on potato diseases and production, based in Turrialba, some 70 km east of the capital city, San José. Under the terms of our visas, Steph was not permitted to work in Costa Rica. I became regional representative for CIP’s Region II (Mexico, Central America, and the Caribbean) in August 1997 when my colleague, Oscar Hidalgo (who was based in Toluca, Mexico) headed to North Carolina to begin his PhD studies.

Our elder daughter Hannah Louise was born in San José in April 1978. Later that year, we took our first home leave in the UK and both sets of grandparents were delighted to meet their first granddaughter.

We spent five happy years in Costa Rica before moving back to Lima at the end of November 1980, and began making plans to move to the Philippines by Easter 1981.

However, in early 1981, a lectureship was created at the University of Birmingham, in the Department of Plant Biology (formerly Botany, where Steph and I had studied), for which I successfully applied. We left CIP at the end of March and had set up home in Bromsgrove (about 13 miles south of Birmingham in north Worcestershire) by the beginning of July.

A decade after we were married, we were already a family of four. In May 1982 Philippa Alice was born in Bromsgrove.

During the 1980s we enjoyed many family holidays, including this one in 1983 on the canals close to home.

Many other family holidays followed, in South Wales, in Norfolk, on the North York Moors, and in 1989, in the Canary Islands.

Hannah (left) and Philippa (right) thrived at local Finstall First School, shown here on their first day of school in 1983 and 1987, respectively.

My work at Birmingham kept me very busy (perhaps too busy), but I particularly enjoyed working with my graduate students (many of them from overseas), and my undergraduate tutees.

All in all, it looked like Birmingham would be a job for life. That was not to be, however. By the end of the 1980s, academic life had sadly lost much of its allure, thanks in no small part to the policies and actions of the Thatcher government. We moved on.

By 1993, we had already been in the Philippines for almost two years, where I had been hired (from July 1991) as head of the Genetic Resources Center (GRC) at the International Rice Research Institute (IRRI) in Los Baños, some 65 km south of Manila in the Philippines. I moved there ahead of Steph and the girls (then aged 13 and nine) who joined me just after Christmas 1991.

In 1993 I learned to scuba dive, a year after Hannah, and it was one of the best things I’ve ever done. Philippa trained a couple of years later.

Steph was quite content simply to snorkel or beachcomb, and we derived great pleasure from our weekends away (about eight or nine a year) at Anilao, 92 km south from Los Baños. In fact, our weekends in Anilao were one of our greatest enjoyments during the 19 years we spent in the Philippines.

Steph became an enthusiastic beader and has made several hundred pieces of jewelry since then. In Los Baños we had a live-in helper, Lilia, and so in the heat of Los Baños, Steph was spared the drudgery of housework or cooking, and could focus on the hobbies she enjoyed, including a daily swim in the IRRI pool, and looking after her garden and orchids.

Hannah and Philippa completed their school education at the International School Manila (ISM) in 1995 and 1999 respectively, both passing the International Baccalaureate Diploma with commendably high scores.

Graduation at ISM: Hannah and Philippa with their friends from around the world.

Traveling to Manila each day from Los Baños had not been an easy journey, due to continual roadworks and indescribable traffic. It was at least two hours each way. By the time Philippa finished school in 1999, the buses were leaving Los Baños at 04:30 in order to reach Manila by the start of classes at 07:15.

In October 1996, Hannah started her university degree in psychology and social anthropology at Swansea University in the UK. However, after two years, she transferred to Macalester College, a highly-rated liberal arts college in St Paul, Minnesota, graduating summa cum laude in psychology and anthropology in May 2000. She then registered for a PhD in industrial and organizational psychology at the University of Minnesota. Philippa began her BSc degree in psychology at the prestigious University of Durham, UK later that same year, in October.

Once Hannah and Philippa had left for university, IRRI paid for return visits each year, especially at Christmas.

Christmas 2001. Michael joined Hannah for the visit.

While my work took me outside the Philippines quite often, Steph and I did manage holidays together in Hong Kong/Macau and Australia. And, together with Philippa, we toured Angkor Wat in Cambodia in December 2000.

But Steph also accompanied me on work trips to Laos, Bali, and Japan. She also joined me and my staff when we visited the rice terraces in northern Luzon in March 2009.

However, we always used our annual home leave allowance to return to the UK, stay in our home in Bromsgrove (which we had purposely left unoccupied), and meet up with family and friends.

Philippa was awarded a 2:1 degree in July 2003, and the graduation ceremony took place inside Durham Cathedral. She then headed off to Vancouver for a year, before returning to the UK and looking for a job, eventually settling in Newcastle upon Tyne where she has lived ever since.

Hannah married Michael in May 2006, and finished her PhD. We flew to Minnesota from the Philippines.

Philippa registered for a PhD in biological psychology at Northumbria University in Newcastle upon Tyne where she was already working.

Professionally, the period between 2001 and my retirement in 2010 was the most satisfying. I had changed positions at IRRI in May, moving from GRC to join the institute’s senior management team as Director for Program Planning and Communications (DPPC). I worked with a great team, and we really made an impact to increase donor support for IRRI’s research program. However, by 2008/9 when my contract was up for renewal, Steph and I had already agreed not to continue with IRRI, but take early retirement and return to the UK.

But not quite yet. IRRI’s Director General, Bob Zeigler, persuaded me to stay on for another year, and organize the celebrations for the institute’s 50th anniversary. Which I duly did, and had great fun doing so.

But as our retirement date approached in April 2010, I was honored by the institute’s Board of Trustees with a farewell party (despedida) coinciding with the 50th anniversary of the very first Board meeting in April 1960.

We flew back to the UK two days later, arriving on Monday 3 May and taking delivery of our new car, a Peugeot 308, the following day.

Philippa and Andi flew off to New York in October 2010 and were married in Central Park. She graduated with her PhD in December.

By 2013 we had been married for four decades, and were well-settled into retirement, enjoying all the opportunities good weather gave us to really explore Worcestershire and neighboring counties, especially as National Trust and English Heritage members. And touring Scotland in 2015, Northern Ireland in 2017, Cornwall in 2018, East Sussex and Kent in 2019, and Hampshire and West Sussex in 2022.

We were, by then, the proud grandparents of three beautiful boys and a girl.

And how could we ever forget a very special day in February 2012, when Steph, Philippa and my former colleague from IRRI, Corinta joined me at Buckingham Palace for an investiture.

Since 2010, we have traveled to the USA each year except during the pandemic years (2020-2022), and only returning there this past May and June. We’ve made some pretty impressive road trips around the USA, taking in the east and west coasts, and all points in between with the exception of the Deep South. Just click here to find a list of those road trips.

In July 2016, a few months after I broke my leg, Hannah and family came over to the UK, and we got together with Phil and Andi and the boys for the first time, sharing a house in the New Forest.

And they came over again in July 2022, to our new home in the northeast of England where we had moved from Bromsgrove in October 2020 at the height of the Covid-19 pandemic.

So it’s 2023, and fifty years have passed since we married.

During our visit to the USA this past May and June, we met up with Roger Rowe and his wife Norma, along the Mississippi River at La Crosse in Wisconsin.

Roger joined CIP in 1973 as head of the Breeding and Genetics Department and was our first boss. Roger also co-supervised my PhD. So it was great meeting up with them again 50 years on.

We’ve been in the northeast just over three years now, and haven’t regretted for a moment making the move north. It’s a wonderful part of the country, and in fact has given us a new lease of life.

Steph has taken great pleasure in developing her new garden here. It’s a work in progress, and quite a different challenge from her garden in Worcestershire, discovering what she can grow and what won’t survive this far north or in the very heavy (and often waterlogged) soil.

22 August 2023

I’ve had much enjoyment writing this blog since 2012, combining my interests of writing and photography. It has certainly given me a focus in retirement. I never thought I’d still be writing as many stories, over 700 now, and approaching 780,000 words. Since returning to the UK, I’ve also tried to take a daily walk of 2-4 miles. However, that’s not been possible these past six months. A back and leg problem has curtailed my daily walk, but I’m hopeful that it will eventually resolve itself and I’ll be able to get out and about locally, especially along the famous North Tyneside waggonways.

After 50 years together, we have much to be thankful for. We’ve enjoyed the countries where we have lived and worked, or visited on vacation. Our daughters and their families are thriving. Hannah is a Senior Director of Talent Management and Strategy for one of the USA’s largest food companies, and Philippa is an Associate Professor of Biological Psychology at Northumbria University.

Sisters!

Collecting potatoes in Peru – following in Jack Hawkes’ footsteps (Part 2)

A year after returning from collecting in Ancash and La Libertad (as described in Part 1) I was heading north once again, this time to the Department of Cajamarca. In a long wheelbase Land Rover, a donation from the British government to CIP. But alone this time, almost. By May 1974 I was already quite fluent in Spanish, and had done more travelling around the country. It was assumed therefore I could look after myself, so we decided I should travel with just one of the CIP drivers, Octavio. I regret I cannot recall his surname.

Just about to head out (May 1974)

Parked on the side of the Panamericana Norte highway north of Lima

Cajamarca is also the capital city of the department, and is one of my favorite places in Peru. At 2700 m elevation, the city lies in a broad valley among rolling hills. The landscape of Cajamarca has a much gentler feel to it than the high peaks of Ancash or further south around Cuzco, or the altiplano surrounding Puno.

We must have split the journey to Cajamarca city. It’s almost 900 km and even today, on better roads, the journey is estimated to take more than 14 hours. North of the coastal city of Trujillo, the road to Cajamarca diverges east from the Panamericana Norte, winding through a lush river valley in the desert, and climbing into the mountains. Dropping down the other side, you eventually are treated to views of the city unfolding in the distance. The climate is spring-like, the food is good (the leche asada or caramel custard is a local treat), and the architecture of the (unfinished) cathedral on the main square of Plaza de Armas is a wonder.

We spent around three weeks travelling to remote areas, but were able to return from time to time to Cajamarca to enjoy the comforts of the Turista Hotel, and the Inca baths and their hot springs.

As with our collecting the previous year, we stopped to chat with farmers, ask about the varieties they and their neighbors cultivated, and requesting a sample of healthy tubers of each variety.

The market town of Bambamarca, 100 km or so north of Cajamarca was particularly interesting. It was a colorful, vibrant scene with many wearing their typical tall sombreros and russet-red ponchos, typical of Cajamarca.

On one day we stopped to chat with one farmer and his wife who became very interested why we were collecting potato varieties, and what we would do with them once back in Lima. They were so pleased to show me this particular variety with its large tubers. It’s one of my favorite images from my time in Peru.

There was even a little time for some sightseeing. Just 10 km northeast from the Plaza de Armas in Cajamarca stands an unusual archaeological site, the Ventanillas de Otuzco, a pre-Inca necropolis with more than 300 niches carved in the rock face. We even found wild tomatoes growing there.

If I have one abiding image of Cajamarca—city and landscape—it would be this one. Having eaten an early breakfast, Octavio and I headed north from the city, climbing above the valley. We stopped almost at the summit so I could take this photo of the Cajamarca valley. If you look carefully you can see the steam rising from the Inca baths in the distance.

Octavio and I got along quite well. He’d never traveled to that part of Peru before and, as a driver from the big city, had very little knowledge of potatoes. We had just the one falling-out, if you can call it that. He would insist in driving downhill along quite treacherous roads in high gear, or even in neutral, relying solely on the brakes alone to control our speed. I had to insist he use low gear to slow the vehicle or he wouldn’t be driving any more until we reached the coast and the Panamerican highway. Anyway, we arrived back in Lima after an incident-free trip.

Later on that year, I returned to Cajamarca with my wife Steph and two English friends from CIP. Again in 1988, as a member of a CIP project review team, I spent a few days in the city and surrounding countryside looking at seed production and storage systems.

When I visited CIP in 2016 as part of a review of the genebank, the staff showed me some herbarium sheets from some of the varieties I had collected on that trip to Cajamarca.

Earlier in 1974, in February, I traveled to Puno and Cuzco in the south of the country with Dr Peter Gibbs from the University of St Andrews, Scotland. He was studying the floral biology of another Andean tuber crop known as oca (Oxalis tuberosa). He had contacted CIP’s Director General to see if anyone might be headed south for fieldwork with whom he could travel.

I’d already decided to carry out some field studies of potato varietal mixtures and was looking for suitable locations. Peter suggested that we might head to Cuyo Cuyo, a municipality just under 250 km northeast of Puno and Lake Titicaca. Famous for its agricultural terraces or andenes, there had been one study in 1951 describing the cultivation of oca in the valley. Peter convinced me that it was worth heading in that direction. Which is precisely what we did.

On this trip we drove a short wheelbase Land Rover, another donation to CIP from the British government. It had a separate cab; the rear was covered with a canvas hood, not the most secure vehicle for venturing into remote parts.

Heading south down the Panamericana Sur, we had a road trip of almost 1300 km ahead of us. I know we stopped in Nazca on the first night, after driving 447 km. From there to Arequipa was another 568 km, and the final leg into Puno was 295 km. I think we must have made it to Arequipa on the second day, resting up before the climb to the altiplano on the third day.

In Puno, we rested for a couple of days, checking our gear, and meeting with some officials from the Ministry of Agriculture for further advice before setting off for Cuyo Cuyo. Peter had developed a taste for algarrobina, a popular Peruvian cocktail, a bit like egg-nog, but with a kick, especially after one too many. We weren’t in the best shape to head off across the altiplano the next day.

Each time I crossed the altiplano it was hard to understand just how people managed to survive in such a harsh environment: flat, cold, and often over 4000 m. Yet we passed farms, growing the bitter and frost-resistant potatoes that are processed to make chuño as well as herding llamas and alpacas. Crossing several rivers, we finally reached the head of the Cuyo Cuyo valley and, descending into the cloud, encountered workmen struggling to clear a landslide. However that gave an opportunity for some impromptu botany, finding a beautiful begonia with flowers as large as saucers.

Once clear of the landslide, and out of the cloud, the most amazing vista opened up before us. The whole valley was terraced and, as we learned over the next few days, supported a rotation system involving potatoes, oca, barley and faba beans (both imported by the Spanish in the 16th century), and a fallow.

Arriving in the village it was important to find somewhere to stay. We hadn’t thought to make any enquiries before setting out for Cuyo Cuyo. There was no hotel, but the postmaster offered us space to set up our camp beds and herbarium drying equipment, and there we stayed for about five days. We were certainly a curiosity with the village children.

Peter set about collecting samples of oca with different floral structures for his study, and to make herbarium specimens to take back to St Andrews. At the time of our visit many of the oca fields were planted in the lower levels of the valley often close to the river. I set off on my own, guided by a local farmer, to potato terraces higher up the valley to study the varietal mixtures and to learn more about the agricultural system. That study was finally published in the journal Euphytica in 1980 and can be read here.

Peter’s oca samples were the devil to dry because of their fleshy stems. When he finally made it back to St Andrews a couple of months later, he found that his ‘dry’ specimens were still alive. So he planted them in a university glasshouse, and had the best of both worlds being able to continue his study with living plants.

Leaving Cuyo Cuyo, we headed back to Puno staying one night there before setting off for Cuzco some 385 km to the northwest.

I was interested in locating another site for study, and we settled on a community near Chinchero outside Cuzco. We hired horses to reach remote fields, and there I collected flower buds (for chromosome counts) from several fields.

It was interesting to find large commercial cultivation of potatoes (for sale in markets like Cuzco) alongside smaller plots of native varieties that farmers grew for home consumption. As I was collecting samples from one field, two women stopped close-by and one of them crouched down to feed her baby. Both were dressed in the typical costume of that region.

Soon we had all the information we thought we needed (in hindsight I would have done things very differently, and at Cuyo Cuyo), and headed back to Cuzco where we left the vehicle to be collected by Zósimo Huamán who was heading south for his own field studies, and who would drive it back to Lima.

While we in Cuzco, we visited the home of Professor César Vargas, a renowned Peruvian botanist, who I had first met in January 1973 when Jack Hawkes introduced me to him. Jack first met Vargas when he was working in Colombia between 1948 and 1951. Also, Vargas’ daughter Martha was an MSc student at St Andrews so it was a good opportunity for Peter also to meet him.

I only made one field trip with Jack Hawkes, in March 1981 just a few weeks before I left CIP to return to the UK and take up a lectureship at The University of Birmingham.

Jack was in Lima on his way back to the UK having led yet another expedition to collect potatoes in Bolivia. He suggested that we take a long weekend to head up into the mountains and see what wild species of potato could be found. A CIP colleague, potato breeder Juan Landeo, came along for the trip.

On the first day, we set off east up the Carretera Central, over Ticlio at 4800 m and on to the smelting town of La Oroya, before heading north to the important mining center of Cerro de Pasco (4330 m), one of the highest (and bleakest) cities in the world.

The next morning we continued north, finally descending to the warmth of Huánuco, a lovely city at just 1880 m. We spent the night there.

I don’t recall if we split the journey back to Lima (or the exact route) or traveled from Huánuco in one day, stopping every now and then to collect potatoes.

Early in the day we came across some farmers using the traditional foot plough or chaqui tacclla. This is an iconic image.

We passed through some awesome landscapes. Even encountering a significant landslide that blocked our path. Closer to the coast the mountains were lost in the clouds as we made our way down the side of the valley.

I learned one very important lesson from Jack Hawkes: that a sound knowledge of the ecology of the species was very important (a point emphasized by Israeli geneticist Gideon Ladizinsky when I took a party of Birmingham students to a genetic resources course near Tel Aviv in 1982).

We’d be driving along, when Jack would suddenly ask us to pull over, saying that we’d find potatoes in the vicinity. Even naming which species we’d be likely to find. And I don’t remember him ever being wrong. It was fascinating to see how his deep knowledge guided his approach to collecting wild potatoes.

This is the only photo of me in the field with Jack, as we collected Solanum multiinterruptum (or was it S. multidissectum?).

It was a great experience, learning more about wild species in the field, from the master. These are memories that will stay with me for years to come.

Collecting potatoes in Peru – following in Jack Hawkes’ footsteps (Part 1)

Professor Jack Hawkes examines a specimen of the wild potato species Solanum raphanifolium in the ruins of Sacsayhuaman outside Cuzco, January 1973

Potatoes are native to the Americas; the wild Solanum species are found from Colorado in the United States, south through Mexico and Central America, and throughout the Andes as far south as northern Argentina. They even grow on the plains of Argentina, Uruguay and Brazil. Different forms of potato were domesticated thousands of years ago in the Andean region and southern Chile. Even today, farmers in the Andes grow (and conserve) a wonderful range of potato varieties.

Over many decades potato scientists made expeditions to the Americas to collect wild and cultivated potatoes, to learn about their biology and ecology, and how they might be used to enhance potato productivity through plant breeding. Among the potato pioneers was my friend, colleague, and mentor, the late Professor Jack Hawkes, a world-renowned expert on potato diversity and taxonomy and a leading light in the genetic resources conservation movement that emerged in the 1960s.

The wonder of potato diversity

I began my own studies on potato under Jack’s tutelage in September 1971 at The University of Birmingham, after graduating with an MSc degree in genetic resources conservation. Jack took me under his wing, so to speak, to teach me about potatoes and prepare me for a posting at the International Potato Center (CIP) in Lima, Peru where (from January 1973) I worked as an Associate Taxonomist for three years. I had just turned 24 the previous November.

Jack made his first trip to South America in 1939 at the age of 23, turning 24 during the course of the expedition in June that year, as a member of the Empire Potato Collecting Expedition to South America and spending nine months collecting wild and cultivated potatoes along the Andes of Argentina, Bolivia, Peru, Ecuador, and Colombia.

Returning to Cambridge in December 1939, just after the Second World War broke out, Jack continued to study the materials collected on the Empire expedition, completing his PhD in 1941. He remained at Cambridge until 1948 when he was seconded by the Government of Colombia to set up a research station for potatoes near Bogota.

In 1952, he returned to the UK, joining The University of Birmingham as a lecturer in the Department of Botany, but he returned to the Americas many times over the next four decades to collect potatoes. Awarded a personal chair in taxonomic botany in 1961, he became Mason Professor of Botany and head of department in 1967.

In 1969 he launched the one year MSc course I referred to earlier, and that’s when I first met him a year later. It would be no exaggeration to state that Jack Hawkes played an incredibly important role in shaping my subsequent career in international agricultural research and academia.

In December 1970, just three months after I arrived in Birmingham, Jack joined his Danish colleague Peter Hjerting on an expedition to collect wild potatoes in Bolivia, accompanied by Jack’s research assistant and PhD candidate Phil Cribb.

Richard Sawyer

The expedition received support from the newly-established International Potato Center (CIP) in Lima whose Director General, Dr Richard Sawyer kindly loaned a four-wheel drive vehicle. Joining the expedition was a young Peruvian scientist, Zósimo Huamán who had been hired by CIP to manage its large germplasm collection of native potato varieties.

While in Lima, Jack was asked to accept Zósimo on the Birmingham MSc course in September 1971. And then Sawyer asked Jack if he could recommend someone to join CIP on a one-year posting to cover for Zósimo while away in Birmingham. Apparently, so Jack later told me, my name immediately came to mind. Perhaps I’d mentioned that I had a burning ambition to visit South America and, in any case, I would graduate just when Zósimo was expected in the UK.

Anyway, to cut a long story short, immediately on his return to Birmingham at the end of February 1971, Jack told me about the opportunity at CIP. Was I interested? There was no question about it.

As it turned out, my departure to Peru was delayed by 15 months while different funding options for my posting were finalized. I began my PhD study, and after he graduated with his MSc in September 1972, Zósimo also registered for a PhD, studying the evolution of a frost-resistant form of cultivated potato known as Solanum ajanhuiri that he and Jack had collected at high altitude in Bolivia.

I departed for Lima on 4 January 1973, and by the beginning of April that year Zósimo had also returned to Peru having completed the first six month residency requirement for his PhD at Birmingham.

With hardly any time to get himself sorted after being outside Peru for 18 months, Zósimo and I organized a trip in May to collect potato varieties from two departments to the north of Lima: Ancash and La Libertad.

To say that I found the experiences beyond my expectations would be an understatement. Peru was everything I hoped it would be when I spent hours poring over a map of the country as a young boy. It is an extremely beautiful country, even if (at least in the 1970s) it was not the easiest country to travel around.

After 49 years, and without access to any notes we made, reports we wrote, or the books in which we recorded the germplasm samples collected, I am unable to detail the routes we took with any degree of confidence, except in the most broad terms. We were away from Lima for almost a month, and explored much of these two departments as best we could: by road, on foot, and on horseback.

At the end of the road, preparing to walk into a distant village; and below, riding back from a side-trip to a village

This was the first collecting trip that I had made. Time to put theory into practice. I bowed to Zósimo’s better knowledge, not only of potatoes and the terrain, but because he was a native Spanish speaker and after just a few months in Peru my Spanish was rudimentary to say the least. Also, as I mentioned earlier, Zósimo already had experience of collecting, having joined the Hawkes-led expedition to Bolivia in 1971.

We headed north on the Panamerican highway, destination Huaraz, the capital of Ancash located in the Callejón de Huaylas, a long north-south valley between the Cordillera Blanca to the east with the highest snow-covered peaks in the country and the Cordillera Negra to the west. Our aim was to explore regions right round these mountain ranges, and we certainly found ourselves in some remote locations.

We moved north into La Libertad, spending a little less time there than in Ancash before heading back to Trujillo on the coast for a well-deserved shower and rest at a good hotel, and better food before heading south to Lima, a journey of 575 km. I don’t recall if we attempted that last sector in one day or made an overnight stop about half way. In any case the journey would have taken about 10 hours or more, and given an incident on the way south that I’ll explain below, maybe we did split the journey.

In 1973, the Peruvian government was led by left-wing-leaning military junta headed by General Juan Velasco Alvarado who came to power in 1968 following a coup d’état. We encountered military checkpoints frequently on our travels in the mountains, often manned by young recruits or conscripts, teenagers even, armed with automatic weapons. Coming from a country where the police never carried firearms (at least then) nor were the armed forces deployed on the streets (that would change in Northern Ireland in the 1970s) I found it extremely disconcerting to be faced with soldiers pointing weapons at me and wondering if their discipline was as tight as I hoped. Needless to say we never encountered any specific threats or hostility.

What particularly struck me during this trip (and others that I made in 1974 and 1975, which I describe in Part 2) was the generosity of almost everyone we met. Farmers were generous with the potato varieties and knowledge they shared with us. Each potato variety collected was carefully labeled with a unique number inscribed on each tuber, and on the paper bags in which they were stored. All the details were recorded in a small booklet; I wonder if these are still archived in the CIP genebank in Lima.

Often we were invited to share a meal with a family, and only on one occasion did I baulk at what was put in front of me: fried cuy or guinea-pig (which are native to Peru and most households keep a small herd of them running around the house ready for the pot). I just couldn’t bring myself to tuck in. Guinea-pigs, to my mind, were furry pets. Needless to say that, as I grew older, such inhibitions diminished.

Despite being memory-deficient when it comes to the route or the places we stayed, there are several anecdotes that are still fresh today.

One experience was particularly emotional. Just 57 km north of Huaraz lies the town of Yungay, and a few kilometers closer to Huaraz, the town of Ranrahirca. On 31 May 1970 a powerful earthquake off the coast west of here, dislodged a massive landslide, a mixture of ice and rocks, that fell from Huascarán, Peru’s highest mountain.

Looking north along the Callejón de Huaylas towards the twin peaks of Huascarán

Travelling at speeds up to 335 kph the landslide quickly reached and obliterated both towns, killing tens of thousands. In Yungay, when we visited almost three years later, the only remains of the town still standing were the cemetery mound with a statue of Christ with outstretched arms, and four palm trees. They had survived, yet everywhere else the landscape was dotted with crosses marking where houses used to stand and presumably families perished. What a sobering sight indeed.

This was the site of Ranrahirca where the town had been obliterated by boulders the size of houses, May 1973

We followed the road south from Huaraz and round to the east of the Cordillera Blanca, to Chavín de Huántar.

The next day we headed north up a steep and extremely muddy road, slipping and sliding from side to side. Fortunately the road was wide and there were no drop-offs, until we reached the highest point. The road levelled off, snaking along the side of the valley, barely wide enough for our Toyota Landcruiser. It was also quite muddy there as well.

We could see there was a drop-off, but given that we were in cloud, couldn’t see more than about 50-100 m ahead. It was only on the return journey and checking our maps that we saw that the side of the road plunged about 1000 m to the valley below. Talk about a stressful situation.

Having enjoyed a good bistek in Chavín that evening, we both got very drunk on Ron Pomalca, regretting sincerely the following morning that we had imbibed so freely. Incidentally, Zósimo found that the rum was also a useful liniment after several hours on horseback, and kept a bottle for that purpose.

On one occasion, we drove as far as we could before walking to two villages some kilometers away. When we arrived at the first village, we found everyone celebrating the jubilee of its founding (and were informed that the next village was also in fiesta mode). We were made welcome, offered refreshments, and talked with village officials before explaining that we had to push on to the next village before it got dark. There we found almost everyone in an advanced state of inebriation, especially the schoolteacher, who spoke a little English.

As special guests on that auspicious day, the mayor invited us to a reception, where the whole village crammed into the town hall. Speeches were made, with Zósimo translating for me. It was clear we would have to respond, especially me as a representative of La Reina Isabel. I frantically whispered to Zósimo how to say such and such in Spanish, writing his translations on the palm of my hand. When it was my turn to make a short speech, I nervously complimented the village on its anniversary and how pleased we were to be there. On sitting down, everyone in that room, at least a hundred men and women, maybe more, came and shook my hand. What a memory.

Zósimo (on the right) beside the teacher, his wife and child in front of his house where we spent the night

Later in the trip in La Libertad, we arrived in one village looking for a hotel. There were two: one had been opened not many months before our arrival there; the other was quite run down. We chose the new hotel, ignoring ‘advice’ that it was flea-infested. Surely that couldn’t be the case? How wrong could we be, waking next morning covered in flea bites and itching madly. Those pesky fleas got everywhere, so we had to endure several days of purgatory until we reached the coast and could send all our gear for cleaning. And take a welcome shower.

Finally, on the return journey south on the Panamerican Highway south of Trujillo, there was a puncture in the rear nearside tyre. We quickly replaced it with the spare, and resumed our journey, hoping to find a grifo or garage soon where the tyre could be repaired. I was driving. Suddenly there was a bang, and the vehicle lurched wildly. I managed to bring it under control, even though the rear was touching the ground. You can imagine our surprise when the wheel passed beside us, travelling at speed ahead. Zósimo and I had each thought the other made a final check of the wheel nuts. They just worked their way loose until the wheel fell off. Our humble jack was not powerful enough to lift the vehicle, but we flagged down a truck driver who used his more robust jack. We retrieved the wheel several hundred meters down the road, and even located all four wheel nuts scattered across the highway. What luck! Fortunately there were no further incidents before we reached CIP’s headquarters in the La Molina district of the Lima.

What an experience, and despite some stressful incidents (and occasional differences of opinion with Zósimo) we returned to Lima after a successful collecting trip. Maybe there were a couple of hundred samples or more to add to CIP’s germplasm collection. That collection eventually grew to around 15,000 samples or accessions but was reduced to its current more manageable size of around 4000 accessions after possible duplicate samples were removed (although converted to botanical or true seed samples before discarding the tubers). On his trips to Peru after 1973 Jack would spend time in the collection at CIP’s high altitude station in Huancayo (3100 m), a six-hour drive east of Lima, working through the germplasm samples and giving his advice about their conservation status. In the photo below, taken in early 1974, I briefly left off my own research to join Jack as he studied different varieties.

In Part 2, I write about the trips I made to Cuyo Cuyo in the south of Peru in February 1974, then to Cajamarca in May the same year. Finally, I describe the trip over a long weekend I made in March 1981 with Jack and a CIP colleague to collect wild potatoes in the mountains northeast from Lima. This was the only time that I went collecting with Jack, but even in that short journey I learned so much.

The Commonwealth Potato Collection – it really is a treasure trove

A few days ago, a friend and former colleague, Dr Glenn Bryan posted a link on his Facebook page to a story—Treasure trove could hold secrets to potato problems—that appeared in the online edition of Dundee’s The Courier on 20 August.

It was all about the Commonwealth Potato Collection (CPC) that is held at The James Hutton Institute at Invergowrie, just west of Dundee.

Glenn leads the Potato Genetics and Breeding Group there, and also has overall responsibility for the CPC, ably assisted by collection curator Gaynor McKenzie.

Glenn and I go back almost 30 years when, as a young scientist at the John Innes Centre (JIC) in Norwich, he was a member of a rice research project, funded by the British government, that brought together staff at the International Rice Research Institute (IRRI) in the Philippines where I was Head of the Genetic Resources Center, the University of Birmingham (where I had been a faculty member for a decade from 1981), and the JIC to use molecular markers to study IRRI’s large and globally-important germplasm collection conserved in its International Rice Genebank.

The Commonwealth Potato Collection has a long and distinguished history, going back more than 80 years, much longer than the rice collection at IRRI. It is one of a handful of potato germplasm collections around the world in which breeders have identified disease and pest resistance genes to enhance the productivity of cultivated varieties. The CPC is particularly important from a plant quarantine perspective because the collection has been routinely tested and cleaned for various pathogens, particularly seed-borne pathogens.

Jack Hawkes

It is a collection with which Steph and I have both a personal and professional connection, from the 1970s and 80s. It’s also the legacy of one man, Professor Jack Hawkes (1915-2007) with whom I had the privilege of studying for both my MSc and PhD degrees.

Let me tell that story.

In December 1938, a young botanist—just 23 years old the previous June—set off from Liverpool, headed to Lima, Peru to join the British Empire Potato Collecting Expedition to South America, the adventure of a lifetime.

Jack in Bolivia in 1939

John ‘Jack’ Gregory Hawkes, a Christ’s College, Cambridge graduate, was destined to become one of the world’s leading potato experts and a champion of the conservation and use of plant genetic resources for food and agriculture.

He was the taxonomic botanist on the 1939 expedition, which was led by experienced plant collector Edwards Kent Balls (1892-1984). Medical doctor and amateur botanist William ‘Bill’ Balfour Gourlay (1879-1966) was the third member of the expedition. Balls and Gourlay had been collecting plants in Mexico (including some potatoes) in 1938 before moving on to Peru for the ‘Empire’ expedition.

The expedition had originally been scheduled to start in 1937, but had to be delayed because of ill health of the original expedition leader, Dr PS Hudson, Director of the Empire Bureau of Plant Breeding and Genetics in Cambridge. Jack had been hired as his assistant. Whilst waiting for the expedition to get underway, Jack took the opportunity—in August 1938—to visit Leningrad to pick the brains of Russian botanists, Drs SM Bukasov, VS Juzepczuk, and VS Lechnovicz who had already collected potatoes in South America. Jack openly acknowledged that ‘as a raw recently graduated student, [he] knew very little about potatoes’.

Nikolai Vavilov

Not only did Jack receive useful advice from these knowledgeable botanists, but he also met with the great geneticist and ‘Father of Plant Genetic Resources’ Nikolai Vavilov on several occasions during his visit to Leningrad and Moscow, ‘an experience that changed [his] life in many ways’. Vavilov had a profound effect on Jack’s subsequent career as an academic botanist and genetic resources pioneer. Alas there do not appear to be any surviving photos of Jack with Vavilov.

‘Solanum vavilovii’ growing at an experiment station near Leningrad in 1938

In Leningrad, Jack took this photo (right) of a wild potato species that had been described as Solanum vavilovii by Juzepczuk and Bukasov in 1937. Sadly that name is no longer taxonomically valid, and vavilovii is now considered simply as a variant of the species Solanum wittmackii that had been described by the German botanist Friedrich August Georg Bitter in 1913.

The Empire expedition lasted eight months from January 1939, covering northern Argentina, Bolivia, Peru, Ecuador, and ending in Colombia (a country where Jack was to reside for three years from 1948 when he was seconded to establish a national potato research station near Bogota).

Route taken by the Empire Potato Collecting Expedition

More than 1150 samples of cultivated and wild potatoes were collected in these five countries as well as a further 46 samples collected by Balls and Gourlay in Mexico in 1938.

Here is a small selection of photographs taken during the expedition, reproduced here by courtesy of the Hawkes family.

By the time the expedition ended in early September 1939, war with Germany had already been declared, and Jack’s return to the UK by ship convoy from Halifax, Newfoundland was not as comfortable as the outbound voyage nine months earlier, docking in Liverpool early in November.

Jack published an official expedition report in March 1941. Then, in 2003, he published an interesting and lengthy memoir of the expedition, Hunting the Wild Potato in the South American Andes.

Redcliffe N Salaman

Potato tubers (and presumably seeds) were shipped back to the UK, and after a quarantine inspection, were planted out in a glasshouse at the Potato Virus Research Station, Cambridge whose director was the renowned botanist (and originally a medical doctor) Redcliffe Nathan Salaman, author of the seminal work on potatoes, The History and Social Influence of the Potato, first published in 1949 and reprinted with a new introduction by Hawkes in 1985. I jealously guard the signed copy that Jack gave me.

On his return to the UK in 1939 Jack began to study the collected germplasm, describing several new species, and completing his PhD thesis (supervised by Salaman) at the University of Cambridge in 1941.

Among the species identified in the course of Jack’s dissertation research was Solanum ballsii from northern Argentina, which he dedicated to EK Balls in a formal description in 1944. However, in his 1963 revised taxonomy of the tuber-bearing Solanums (potatoes), Jack (with his Danish colleague Jens Peter Hjerting, 1917-2012) recognized Solanum ballsii simply as a subspecies of Solanum vernei, a species which has since provided many important sources of resistance to the potato cyst nematode.

The 1939 germplasm was the foundation of the Empire Potato Collection. When the collection curator Dr Kenneth S Dodds was appointed Director of the John Innes Institute in Bayfordbury in 1954, the collection moved with him, and was renamed the Commonwealth Potato Collection.

By the end of the decade (or early 1960s) the CPC was on the move again. This time to the Scottish Plant Breeding Station (SPBS) at Pentlandfield just south of Edinburgh when Dr Norman W Simmonds moved there in 1959. He rose through the ranks to become the station’s Director.

But that was not the end of the CPC’s peripatetic existence. It remained at the SPBS until the early 1980s, when the SPBS amalgamated with the Scottish Horticultural Research Institute (which became the Scottish Crop Research Institute or SCRI, and now known as the James Hutton Institute), and the collection moved to its present site near Dundee.

I am not sure how much the CPC grew in the intervening years, but there was a significant boost to the size and importance of the collection around 1987. Let me explain.

As I already mentioned, Jack spent three years in Colombia from 1948, returning to the UK in 1951 when he was appointed Lecturer in Taxonomy in the Department of Botany at the University of Birmingham. He was given a personal chair as Professor of Taxonomic Botany in April 1961, and became Head of Department and Mason Professor of Botany in July 1967. He remained at Birmingham until retirement in September 1982.

It was during his Birmingham years that Jack’s work on the tuber-bearing Solanums expanded significantly with several important monographs and taxonomic revisions published, based on his own field work over the years and experimental studies back at Birmingham on the potato samples he brought back to the UK and which formed an important collection in its own right. Because of the quarantine threat from these seeds (particularly of sexually-transmitted pathogens or new variants of potato viruses already present in the UK), Jack had a special licence from the then Ministry of Agriculture, Fisheries and Food (MAFF, now DEFRA) to maintain his collection at Birmingham. I’ve written about that special quarantine situation here.

In 1958, with Peter Hjerting and young research assistant Richard Lester (who later joined the Department of Botany as a Lecturer), Jack made a six month expedition to the USA , Mexico, and Central America. Here is an account of that trip. Besides potatoes, many other species were made for other institutions and botanic gardens.

Just three months after I arrived at Birmingham in September 1970 to enrol on the MSc course on plant genetic resources, Jack was off on his travels once again, this time to Bolivia (report) accompanied by Peter Hjerting once again, his research assistant Phil Cribb and, in South America by Zósimo Huamán from the International Potato Center (CIP) and Moisés Zavaleta and others from Bolivia. Jack and Peter made another trip to Bolivia in 1974 (with research assistant Dave Astley), and another in 1980. They published their monograph of The Potatoes of Bolivia in 1989.

Here are some images from the 1971 expedition, courtesy of Phil Cribb.

In September 1971, Zósimo Huamán and Moisés Zavaleta came to Birmingham to study on the genetic resources MSc course. In that same cohort was a young botanist, Stephanie Tribble, recently graduated from the University of Wales – Swansea (now Swansea University). During the summer of 1972, Steph and I became ‘an item’, so-to-speak. However, by then I was already making plans to leave the UK and join CIP in Lima by January 1973, and on graduation, Steph was keen to find a position to use the experiences and skills she had gained on the course.

Just at that time, a Scientific Officer position opened at the SPBS, as assistant to Dalton Glendinning who was the curator of the CPC. Steph duly applied and was appointed from about October that year. Jack must have supported her application. Coincidentally, the MSc course external examiner was no other that Norman Simmonds who met Steph during his course assessment.

I moved to Peru in January 1973, and within a few days discovered that Jack had mentioned Steph to CIP’s Director General, Richard Sawyer. Well, to cut a long story short, Steph was offered a position as Assistant Geneticist at CIP, to support management of CIP’s large potato collection, similar to the role she’d had at Pentlandfield. She resigned from the SPBS and joined me in Lima in July that year. We married there in October. We remained with CIP in Peru and Central America for another eight years

In April 1981 I was appointed Lecturer in Plant Biology at Birmingham, 18 months before Jack’s retirement, the aim being that I would assume Jack’s teaching commitments on the MSc course. When I also took over the Hawkes potato collection in 1982, I had high hopes of identifying funding for biosystematics and pre-breeding research. That was not the case, and as the collection needed a dedicated glasshouse and technician I could not justify (nor financially support) holding on to such valuable research space. And, in any case, continuing with the Hawkes collection was actually blocking the opportunities for other potato research because of the MAFF-imposed restrictions.

Dave Downing was the glasshouse technician who carefully managed the Hawkes collection at Birmingham for many years.

So, with some regret but also acknowledging that Jack’s collection would be better placed elsewhere, I contacted my colleagues at the CPC to see if they would be interested to receive it—lock, stock, and barrel. And that indeed was what happened. I’m sure many new potato lines were added to the CPC. The germplasm was placed in quarantine in the first instance, and has passed through various stages of testing before being added officially to the CPC. Throughout the 80s and 90s Jack would visit the CPC from time-to-time, and look through the materials, helping with the correct identification of species and the like.

His interest in and contributions to potato science remained with him almost up to his death in 2007. By then he had become increasingly frail, and had moved into a care home, his wife of more than 50 years, Barbara, having passed away some years previously. By then, Jack’s reputation and legacy was sealed. Not only has his scientific output contributed to the conservation and use of potato genetic resources worldwide, embodied in the CPC that he helped establish all those decades earlier, but through the MSc course that he founded in 1969, hundreds of professionals worldwide have continued to carry the genetic conservation torch. A fine legacy, indeed!

Growing potatoes – growing professionally

November 1980. After almost five years (from April 1976) Steph and I were preparing to leave Costa Rica, the small Central American country sandwiched between Nicaragua to the north and Panama to the south. Our elder daughter Hannah was born there in April 1978. But our time in that beautiful country was coming to an end, and we were headed back to Lima.

So how come I ended up in Costa Rica working on potatoes, since agriculture there is dominated by rice and beans? And coffee and bananas, of course. Potatoes are small beer [1].

Let me explain.

It all started in January 1973, when I joined the staff of the International Potato Center (CIP) in Lima and, in the process, fulfilled an ambition I’d had since I was a small boy: to visit Peru.

During the three years I was based in Lima, working as an Associate Taxonomist and helping to conserve CIP’s large collection of native Andean potato varieties, I completed research for my PhD degree, awarded by the University of Birmingham in December 1975.

Earlier that year, in April, I returned to Birmingham to complete the residency requirements for my degree, and to submit my thesis (which was examined in October). However, before leaving for the UK, I had discussions with CIP’s Director General, Richard Sawyer, about rejoining CIP after I had completed my PhD. I wanted to broaden my horizons and learn more about and contribute to potato production around the world, rather than continue working with the potato collection or taxonomy research. He offered me a post-doctoral position in CIP’s Outreach Program, being posted to one of the regional offices.

Exploring options
In 1975, CIP’s Region II program, encompassing Mexico, Central America, and the Caribbean, had its regional office in Toluca, Mexico (about 64 km west of Mexico City). Potatoes are not a major crop in this region—maize and beans being the staples—although they are locally and economically important in each country.

It was a year of transition. CIP’s regional representative at that time, Ing. Agr. MS Manuel J. Villareal González, had just been named leader of Mexico’s national potato program (in Toluca). My Lima colleague, Ing. Agr. MS Oscar Hidalgo, a plant pathologist, took over as Region II leader and moved to Mexico.

The other members of the CIP team in Toluca were local support staff: José Gómez and secretary Guillermina Guadarrama, formerly employees of the Rockefeller Foundation potato program, and some field and glasshouse technicians.

Jose and Guillermina

CIP management proposed setting up a sub-regional office in Costa Rica, without yet deciding what its programmatic responsibility and research focus might be.

To explore various possibilities, Steph and I were asked to visit Costa Rica and Mexico in April on our way back to the UK. And that’s what we did. I should add that I was nervous the whole trip. Why? I was carrying a briefcase full of my thesis research data. I was paranoid that some light-fingered individual might relieve me of the briefcase. There was no computer cloud storage in those days, let alone floppy disks or flash drives.

For many years it was not possible to fly direct between Lima and San José, the capital of Costa Rica. The journey inevitably required a stop-over in Panama City, usually overnight. On our trip north we stayed at the airport hotel but had time enough to explore parts of the city center (not the Canal Zone, unfortunately). And that’s when we had our first McDonald’s hamburgers. I have this distinct memory of my immediate boss, head of CIP’s Dept. of Plant Breeding & Genetics, Dr. Roger Rowe, coming back to Lima from one of his home leaves in the USA and telling us all about these ‘new’ hamburger joints that we should try when we had the opportunity. I had thought that, in 1975, McDonald’s was new to Panama, but from what I have found on the internet, McDonald’s opened its first restaurant there in 1971. Notwithstanding, it was a first for us.

Drs. Luis Carlos Gonzalez (L) and Rodrigo Gamez (R)

My Lima colleague, bacteriologist and head of CIP’s Dept. of Plant Pathology & Nematology, Dr. Ed French made arrangements for us to visit with fellow bacteriologist Dr. Luis Carlos Gonzalez Umaña and plant virologist Dr. Rodrigo Gámez Lobo (who, in later years went on to found and become President of the renowned INBio, the Instituto Nacional de Biodiversidad) at the University of Costa Rica.

Luis Carlos and Rodrigo made us very welcome and, with the leader of the Costarrican potato program, Ing. Agr. Luis Fernando Cartín, took us to see potatoes growing on the slopes of the Irazú Volcano east of San Jose, to labs in the university, and, as a side ‘tourist’ visit, to the Instituto Clodomiro Picado nearby where anti-snake venom serum is produced on a large scale (often in horses). Costa Rica has more than 20 highly venomous snake species.

I think we spent about four days in Costa Rica before travelling on to Mexico. We certainly came away from Costa Rica with a favorable impression. San José is dominated by a stunning landscape of volcanoes (Poás, Irazú, Turrialba), some active or recently active, covered in lush, tropical forest and, on the lower slopes, coffee plantations for which the country is famous. Back in the day, San José was a small city of about 456,000 inhabitants.

In Mexico, we stayed with our friends from Lima, John and Marian Vessey who had moved there in 1974 to work at the International Maize and Wheat Improvement Center (CIMMYT) near Mexico City. Apart from a visit to the potato program in Toluca, we had the opportunity for some sightseeing, with a memorable visit to the pre-Columbian pyramids at Teotihuacán about 32 km north from CIMMYT.

Settling on Costa Rica
Steph and I returned to Lima just after Christmas, all set to move on later in 1976. But where? A decision had not yet been made about Costa Rica.

Meanwhile, a new Director of CIP’s Outreach Program, Dr. Ken Brown, had been appointed while I was back in the UK, and joined CIP in January. In due course, Outreach became the Regional Research Program. As both Ken and his family (wife Geraldine, and five boys) and Steph and I were staying in the center’s guest house for several weeks, we got to know the Browns quite well.

Prof. Luis Sequeira

In order to hasten our move to Region II, we needed to identify an appropriate international institute to host my posting in Costa Rica. So, Roger Rowe, Ed French, and I flew to Costa Rica for a week in early January [2]. There we met with Luis Carlos and Professor Luis Sequeira from the University of Wisconsin at Madison, a world renowned plant bacteriologist (and Costarrican by birth) with whom Luis Carlos had completed his PhD, who happened to be visiting family at the time.

We visited sites on the Irazú Volcano and near Alajuela (a regional town northwest of San José) where Luis Carlos was testing potato breeding lines for resistance to bacterial wilt.

We also visited the Tropical Agricultural Research and Higher Education Center (CATIE), a regional center in Turrialba dedicated to research and graduate education in agriculture, and the management, conservation and sustainable use of natural resources, established originally in 1942 as the headquarters of the Inter-American Institute for Agricultural Sciences (IICA).

The CATIE ‘Henry Wallace’ administration building

CATIE plant pathologist Dr. Raul Moreno from Chile explains the focus of the center’s farming systems research to (L-R) Luis Sequeira, Ed French, and Roger Rowe.

Turrialba is a small town just over 70 km due east of San José, although at a much lower elevation—around 650m compared with almost 1200m in the city.

The drive to Turrialba from San José via Cartago was not straightforward. Until around 1978 (or maybe later) the section between Cartago and Turrialba was a dirt road, and quite dangerous. It was also the main route from the Caribbean port of Limón to San José so there was a continual stream of heavy (and noisy) trucks travelling between the two cities. The road passed through a zone of frequent low cloud (neblina) with reduced visibility, sometimes quite severely. And, passing through several sugarcane plantations, there would be tractors towing ‘trains’ of carts carrying harvested cane snaking along the road to local sugar mills, and often without displaying any hazard lights. With the state of the road, the frequency of the heavy traffic, and limited visibility, one could get stuck behind one of these slow-moving ‘trains’ for many kilometers. Very frustrating!

At CATIE, we met with the Acting Director, Dr. Jorge Soria (a cocoa breeder) to discuss signing an agreement between CIP and CATIE that would allow me to work from CATIE as a regional base, and set up a research program to breed potatoes for hot humid climates. Turrialba has an average annual temperature of 22.9°C (73.2°F), and more than 2854 mm (or 112.4 inch) of rainfall per year. The wettest months are May to December, with heaviest rainfall in June and July. This, we assumed, would be an ideal, if not challenging environment in which to attempt to grow potatoes.

Anyway, to cut a long story short, an agreement was signed between CIP and CATIE, under which I was to be attached to CATIE’s Crops Department. It was also agreed that CIP would contribute to CATIE’s cropping systems program (funded through USAID’s Regional Office for Central America and Panama, ROCAP) once suitable potato varieties had been identified.

Steph and I headed to Costa Rica in early April 1976, and we remained there until the end of November 1980. I’ve been back there just once, in 1997.

Getting started in Turrialba
Back in 1976, I can’t deny that I was rather daunted about setting out on my own. I’d turned 27 only the previous November. And communicating with colleagues back in Lima was not straightforward, as I have described in another post.

We didn’t plant our first potato experiments in Turrialba until May 1977 to check whether any varieties would yield under the warm and humid conditions there. Instead, we were faced with bacterial wilt, a devastating disease of potatoes and other related crops like tomato (as well as bananas!), about which I have blogged before.

Between arriving in Costa Rica the previous year and then, I’d had to renovate screenhouses for our research, acquire a vehicle (that took several months), hire a research assistant and a secretary, as well as attend to other regional duties that Oscar Hidalgo asked me to undertake. In fact within a few weeks of arriving in Costa Rica he whisked me off to Mexico for a month to participate in a potato production course, leaving Steph on her own in (to her) a very strange Turrialba.

Within a couple of months or so, I’d hired a young man, Jorge Aguilar Martinez, as my research assistant. Jorge lived in Santa Rosa, a small village just outside Turrialba, where his father grew coffee on a small farm (finca). Jorge was 20 in June that year, recently married to Carmen (a secretary in the animal husbandry department at CATIE), and with a small boy, Leonardo (who is now Head of Information and Communication Technology at CATIE).

Jorge Aguilar

Jorge had applied for a position in the Crops Department at CATIE before I arrived there, but there were no vacancies. He seemed an ideal candidate: keen, interested to get on in the world. He was studying at night at the local campus of the University of Costa Rica for a qualification in business management. Apart from his coffee background, he had no field experience in crop agronomy, let alone potatoes! But Jorge was a quick learner. In fact, we learned a lot together how to grow potatoes. What particularly impressed me about him was his willingness to innovate, look for solutions. And have a flexible attitude to how we worked. We got the job done, and that often meant leaving for our experimental field plots higher up one of the nearby volcanoes before daybreak, and not returning to Turrialba until late in the afternoon once everything had been completed.

Then a young woman, Leda Avila, from Alajuela joined my project as a bilingual secretary. Her support was fantastic. She had a bubbly and confident character, and was always curious to understand exactly what we were doing in the field. One day she asked me if she could join us on one of our visits to experimental plots we had planted on the slopes of the two local volcanoes, Irazú and Turrialba. She told me that as she typed research reports for Lima she had no idea what the work involved, but wanted to find out. So, one day, and donning her field boots, Leda joined the CIP team in the field.

She was so enthusiastic about her first field experience that she would join us thereafter as and when circumstances permitted. Much to the consternation of our CATIE colleagues. They’d never heard of such a thing. But to me, it just made sense to include Leda as a key member of the team.

Moisés Alonso Pereira

In late 1977, Oscar Hidalgo registered for his PhD at North Carolina State University, and left for the USA. On Ken Brown’s recommendation, Richard Sawyer asked me to take over leadership of the Region II Program. As a consequence, my travel schedule increased significantly (especially as we were developing an important cooperative program on potatoes involving six countries, PRECODEPA), and I had to find permanent technical support for Jorge. I hired Moisés Alonso Pereira as Research Technician, who was 17 or 18 then.

Searching for resistance to bacterial wilt (caused by the pathogen Ralstonia solanacearum) and ways to control it became an important focus of our research in Turrialba. But we also developed rapid multiplication techniques for seed production, and that work accelerated once my colleague and dear friend, Jim Bryan, joined the project in Costa Rica for one year in the late seventies, seen in some of the photos below passing on his encyclopedic knowledge about seed production and rapid multiplication techniques to Jorge and others. We also trained potato scientists from neighboring countries about these techniques through PRECODEPA.

At the same time as we were developing these rapid multiplication methods, my colleagues Bob Booth and Roy Shaw in Lima were adapting diffuse light potato storages for use on farm. We took one of their designs, and adapted it for use in Turrialba. With a double sandwich of fiberglass panels, a wide roof overhang to shade the sides, and an air conditioner to drop the temperature to a reasonable level (it was often more than 30ºC outside) we could successfully store potatoes for several months.

Turrialba became a prime site for testing potato varieties for their resistance to bacterial wilt, and CIP scientists from Lima would pass through to see for themselves how we were getting on. Given his interest and expertise in bacterial wilt it wasn’t surprising that Ed French visited us on at least one occasion.

We also worked with colleagues in the Ministry of Agriculture and Animal Husbandry (MAG) in San José to test different potato lines against various diseases such as viruses, and worked with farmers to find ways to increase productivity.

The productivity of many potato farms was quite low. Why? Overuse of fertilizers and agrochemicals, and not applying these in the most effective way to control pests and diseases, especially control of the late blight disease to which the two main varieties Atzimba and Rosita were highly susceptible. Many farmers worked on the basis that twice the dose of a fungicide, for example, would provide twice the control. Sadly that was never the case. Working with individual farmers was possible, but having the potato growers association on side was important. And their president was a young and forward-looking farmer, Olman Montero.

With Olman Montero on his farm on the slopes of the Irazu volcano.

Our work led to a few publications. Scientific publication was always welcome, but was never a driving force in our work. We were more concerned to make a difference in farmers’ fields by providing clean seed, improving productivity, identifying resistant potato varieties, or managing diseases in the field.

The five years that I spent in Costa Rica were among the best of my career. I really had to become self-reliant, learning to stand on my own two feet and grow professionally as a scientist and a project manager. There was no alternative. Being so far from CIP headquarters in Lima, and with communications vastly slower than today, I just couldn’t call on someone if I found myself in a spot of bother. Phone calls had to be booked at least a day in advance, or we could use telex – who remembers that? Otherwise I just mailed quarterly progress reports to keep everyone up to date with what was going on in Central America, and whether I was keeping to the work plans developed in December each year when the Regional Research staff from around the world congregated in Lima for a two week planning meeting. Ken Brown was an excellent Regional Research director; he let me and my Regional Research colleagues get on with things with only minor adjustments as and when necessary (keeping his staff ‘on a light rein’), so different from today when scientists are assailed frequently and from many quarters to account for their work and performance.

I owe a great debt to Jorge, Moisés, and Leda for all their contributions to the success of the CIP project in Costa Rica. And all my friends and colleagues in Costa Rica’s Ministry of Agriculture and Animal Husbandry, as well as other programs contributing to PRECODEPA.

It was with some sadness that Steph, Hannah, and I upped sticks and moved back to Lima. You might ask why we would make such a move when things were going well in the Costa Rica program. By November 1980 I felt that I had achieved what I’d been sent there for, and even if I stayed on for another year or so, the scope of the work wouldn’t have changed significantly. In any case, the PRECODEPA project was ticking along quite nicely, managed by the national programs themselves, and everyone felt that a more distant relationship with CIP would allow the project to grow and mature. In any case, I was also looking for another potato challenge. And I expected that to come with another Regional Research posting. Little did I know, at the end of November that year, what life would have in store for me in 1981 [3].

Where are they now?
Since leaving Costa Rica at the end of November 1980, I have only been back to Costa Rica once, in 1997 when I was managing a worldwide project on rice biodiversity for the International Rice Research Institute (IRRI) funded by the Swiss government. I did meet both Jorge and Leda on that trip; I don’t recall if I saw Moisés during that visit to Turrialba. I stayed a couple of days in Turrialba. Maybe Jorge, Moisés and I spent an evening at the hilltop bar-restaurant at Turrialtico (now a fancy lodge) near CATIE where we would venture to enjoy a few beers (and some typical bar snacks or bocas) after a day in the field. And I had mostly lost contact with all three former colleagues—until quite recently. Such is the power of social media!

Jorge, Leda, and Moisés are all now retired, more or less, although involved in various volunteer activities. They would be in their early to mid-sixties now.

Jorge continues to live in Turrialba, and still manages a small finca on a part-time basis. He and his wife Carmen have three sons and two granddaughters. Sofía and Amanda are Leonardo’s daughters.

After leaving CATIE in early 1980, Leda returned to Alajuela, and spent many years working at the headquarters of IICA on the outskirts of San José. She has enjoyed traveling in her retirement, most recently in Myanmar in 2019.

She has one son, Enrique (29) who I met in 1997. I stayed with Leda for a couple of nights in Alajuela, and Enrique graciously gave me his room.

Moisés now lives in the La Pitahaya neighborhood of Cartago, a city at the heart of the Costarrican potato industry, lying more or less halfway between San José and Turrialba.

Leda, Moisés, and José Alonso

With his second wife Leda, he has one son José Alonso, who celebrated his 11th birthday just a few days ago. Moisés also has two daughters Ana Amelia (26) and Karen (24) from his first marriage. He also has two granddaughters aged sixteen and fifteen.

It’s wonderful to have reconnected with old friends.

[1] In 1983, I contributed a short piece on potatoes in Costa Rican Natural History, a book edited by eminent tropical biologist, Daniel Janzen who spent many years studying biodiversity in Costa Rica.

[2] I have two enduring memories of that trip. Actually, of the flight from Lima to Panama, and the return. As I mentioned earlier, there were no direct flights from Lima to Costa Rica back in the day. We took an early morning flight (around 06:30 or so) on Air Panama from Lima to Panama City, with an onward connection there to San José. Hardly had the aircraft (a Boeing 727) lifted off the runway in Lima when it was ‘open bar’ for the remainder of the flight. I think Roger, Ed, and I all enjoyed rum cocktails before breakfast! Then on the return flight from Panama (I have this idea at the back of my mind that it was a Braniff DC8 flight), we hit an air pocket somewhere over the Colombian Andes, and it felt as though the plane dropped 1000 feet. Bang! That was my first experience of some serious turbulence, but not the last by a long chalk over the next 45 years.

[3] We returned to Lima, with the expectation of moving to Brasilia (for the southern cone countries of South America). When that fell through, the next option was to join the CIP program for Southeast Asia, based in Los Baños in the Philippines. In the event, that didn’t come about since I had applied for a faculty position in the Department of Plant Biology (formerly Botany) at the University of Birmingham, being offered the position in January 1981. We moved back to the UK in March that year. It would be another decade before landing up in the Philippines. But that’s another story.

Potatoes or rice?

I graduated in July 1970 from the University of Southampton (a university on England’s south coast) with a BSc Hons degree in botany and geography. ‘Environmental botany’ actually, whatever that meant. The powers that be changed the degree title half way through my final (i.e. senior) year.

Anyway, there I was with my degree, and not sure what the future held in store. It was however the beginning of a fruitful 40 year career in international agricultural research and academia at three institutions over three continents, in a number of roles: research scientist, principal investigator (PI), program leader, teacher, and senior research manager, working primarily on potatoes (Solanum tuberosum) and rice (Oryza sativa), with diversions into some legume species such as the grasspea, an edible form of Lathyrus.

Potatoes on the lower slopes of the Irazu volcano in Costa Rica, and rice in Bhutan

I spent the 1970s in South and Central America with the International Potato Center (CIP), the 1980s at the University of Birmingham as a Lecturer in the School of Biological Sciences (Plant Biology), and almost 19 years from July 1991 (until my retirement on 30 April 2010) at the International Rice Research Institute (IRRI) in the Philippines¹.

I divided my research time during those 40 years more or less equally between potatoes and rice (not counting the legume ‘diversions’), and over a range of disciplines: biosystematics and pre-breeding, genetic conservation, crop agronomy and production, plant pathology, plant breeding, and biotechnology. I was a bit of a ‘jack-of-all-trades’, getting involved when and where needs must.

However, I haven’t been a ‘hands-on’ researcher since the late 1970s. At both Birmingham and IRRI, I had active research teams, with some working towards their MSc or PhD, others as full time researchers. You can see our research output over many years in this list of publications.

Richard Sawyer

Very early on in my career I became involved in research management at one level or another. Having completed my PhD at Birmingham in December 1975 (and just turned 27), CIP’s Director General Richard Sawyer asked me to set up a research program in Costa Rica. I moved there in April 1976 and stayed there until November 1980.

In these Covid-19 lockdown days, I’m having ample time to reflect on times past. And today, 30 April, it’s exactly 10 years since I retired.

Just recently there was a Twitter exchange between some of my friends about the focus of their research, and the species they had most enjoyed working on.

And that got me thinking. If I had to choose between potatoes and rice, which one would it be? A hard decision. Even harder, perhaps, is the role I most enjoyed (or gave me the most satisfaction) or, from another perspective, in which I felt I’d accomplished most. I’m not even going to hazard a comparison between living and working in Peru (and Costa Rica) versus the Philippines. However, Peru has the majesty of its mountain landscapes and its incredible cultural history and archaeological record (notwithstanding I’d had an ambition from a small boy to visit Peru one day). Costa Rica has its incredible natural world, a real biodiversity hotspot, especially for the brilliant bird life. And the Philippines I’ll always remember for all wonderful, smiling faces of hard-working Filipinos.

And the scuba diving, of course.

Anyway, back to potatoes and rice. Both are vitally important for world food security. The potato is, by far, the world’s most important ‘root’ crop (it’s actually a tuber, a modified underground stem), by tonnage at least, and grown worldwide. Rice is the world’s most important crop. Period! Most rice is grown and consumed in Asia. It feeds more people on a daily basis, half the world’s population, than any other staple. Nothing comes close, except wheat or maize perhaps, but much of those grains is processed into other products (bread and pasta) or fed to animals. Rice is consumed directly as the grain.

Just 24 when I joined CIP as a taxonomist in January 1973, one of my main responsibilities was to collect potato varieties in various parts of the Peruvian Andes to add to the growing germplasm collection of native varieties and wild species. I made three trips during my three years in Peru: in May 1973 to the departments of Ancash and La Libertad (with my colleague, Zósimo Huamán); in May 1974 to Cajamarca (accompanied by my driver Octavio); and in January/February 1974 to Cuyo-Cuyo in Puno and near Cuzco, with University of St Andrews lecturer, Dr Peter Gibbs.

Top: with Octavio in Cajamarca, checking potato varieties with a farmer. Bottom: ready for the field, near Cuzco.

My own biosystematics/pre-breeding PhD research on potatoes looked at the breeding relationships between cultivated forms with different chromosome numbers (multiples of 12) that don’t naturally intercross freely, as well as diversity within one form with 36 chromosomes, Solanum x chaucha. In the image below, some of that diversity is shown, as well as examples of how we made crosses (pollinations) between different varieties, using the so-called ‘cut stem method’ in bottles.

Several PhD students of mine at Birmingham studied resistance to pests and diseases in the myriad of more than 100 wild species of potato that are found from the southern USA to southern Chile. We even looked at the possibility of protoplast fusion (essentially fusion of ‘naked’ cells) between different species, but not successfully.

I developed a range of biosystematics projects when taking over leadership of the International Rice Genebank at IRRI, publishing extensively about the relationships among the handful (about 20 or so) wild rice species and cultivated rice. One of the genebank staff, Elizabeth Ma. ‘Yvette’ Naredo (pointing in the image below) completed her MS degree under my supervision.

Although this research had a ‘taxonomic’ focus in one sense (figuring out the limits of species to one another), it also had the practical focus of demonstrating how easily species might be used in plant breeding, according to their breeding relationships, based on the genepool concept of Harlan and de Wet, 1971 [1], illustrated diagrammatically below.

When I transferred to Costa Rica in 1976, I was asked to look into the possibility of growing potatoes under hot, humid conditions. At that time CIP was looking to expand potato production into areas and regions not normally associated with potato cultivation. One of the things I did learn was how to grow a crop of potatoes.

I was based in Turrialba (at the regional institute CATIE), at around 650 masl, with an average temperature of around 23°C (as high as 30°C and never much lower than about 15°C; annual rainfall averages more than 2800 mm). Although we did identify several varieties that could thrive under these conditions, particularly during the cooler months of the year, we actually faced a more insidious problem, and one that kept me busy throughout my time in Costa Rica.

Shortly after we planted the first field trials on CATIE’s experiment station, we noticed that some plants were showing signs of wilting but we didn’t know the cause.

Luis Carlos González

Fortunately, I established a very good relationship with Dr Luis Carlos González Umaña, a plant pathologist in the University of Costa Rica, who quickly identified the culprit: a bacterium then known as Pseudomonas solanacearum (now Ralstonia solanacearum) that causes the disease known as bacterial wilt.

I spent over three years looking into several ways of controlling bacterial wilt that affects potato production in many parts of the world. An account of that work was one of the first posts I published in this blog way back in 2012.

The other aspect of potato production which gave me great satisfaction is the work that my colleague and dear friend Jim Bryan and I did on rapid multiplication systems for seed potatoes.

Being a vegetatively-propagated crop, potatoes are affected by many diseases. Beginning with healthy stock is essential. The multiplication rate with potatoes is low compared to crops that reproduce through seeds, like rice and wheat. In order to bulk up varieties quickly, we developed a set of multiplication techniques that have revolutionised potato seed production systems ever since around the world.

AS CIP’s Regional Representative for Mexico, Central America, and the Caribbean (known as CIP’s Region II), I also contributed to various potato production training courses held each year in Mexico. But one of our signature achievements was the launch of a six nation research network or consortium in 1978, known as PRECODEPA (Programa REgional COoperativo DE PApa), one of the first among the CGIAR centers. It was funded by the Swiss Government.

Shortly after I left Costa Rica in November 1980, heading back to Lima (and unsure where my next posting would be) PRECODEPA was well-established, and leadership was assumed by the head of one of the national potato program members of the network. PRECODEPA expanded to include more countries in the region (in Spanish, French, and English), and was supported continually by the Swiss for more than 25 years. I have written here about how PRECODEPA was founded and what it achieved in the early years.

I resigned from CIP in March 1981 and returned to the UK, spending a decade teaching at the University of Birmingham.

Did I enjoy my time at Birmingham? I have mixed feelings.

I had quite a heavy teaching load, and took on several administrative roles, becoming Chair of the Biological Sciences Second Year Common Course (to which I contributed a module of about six lectures on agricultural ecosystems). I had no first teaching commitments whatsoever, thank goodness. I taught a second year module with my colleague Richard Lester on flowering plant taxonomy, contributing lectures about understanding species relationships through experimentation.

Brian Ford-Lloyd

With my close friend and colleague Dr Brian Ford-Lloyd (later Professor), I taught a final year module on plant genetic resources, the most enjoyable component of my undergraduate teaching.

One aspect of my undergraduate responsibilities that I really did enjoy (and took seriously, I believe—and recently confirmed by a former tutee!) was the role of personal tutor to 1st, 2nd and 3rd year students. I would meet with them about once a week to discuss their work, give advice, set assignments, and generally be a sounding board for any issues they wanted to raise with me. My door was always open.

Most of my teaching—on crop diversity and evolution, germplasm collecting, agricultural systems, among others—was a contribution to the one year (and international) MSc Course on Conservation and Utilization of Plant Genetic Resources on which I had studied a decade earlier. In my travels around the world after I joined IRRI in 1991, I would often bump into my former students, and several also contributed to a major rice biodiversity project that I managed for five years from 1995. I’m still in contact with some of those students, some of whom have found me through this blog. And I’m still in contact with two of my classmates from 1970-71.

Research on potatoes during the 1980s at Birmingham was not straightforward. On the one hand I would have liked to continue the work on wild species that had been the focus of Professor Jack Hawkes’ research over many decades.

With Jack Hawkes, collecting Solanum multidissectum in the central Andes north of Lima in early 1981 just before I left CIP to return to the UK. This was the only time I collected with Hawkes. What knowledge he had!

He had built up an important collection of wild species that he collected throughout the Americas. I was unable to attract much funding to support any research projects. It wasn’t a research council priority. Furthermore, there were restrictions on how we could grow these species, because of strict quarantine regulations. In the end I decided that the Hawkes Collection would be better housed in Scotland at the Commonwealth Potato Collection (or CPC, that had been set up after the Empire Potato Collecting Expedition in 1938-39 in which Jack participated). In 1987, the Hawkes Collection was acquired by the CPC and remains there to this day.

Dave Downing was the department technician who looked after the potato collection at Birmingham. He did a great job coaxing many different species to flower.

Having said that, one MSc student, Susan Juned, investigated morphological and enzyme diversity in the wild species Solanum chacoense. After graduating Susan joined another project on potato somaclones that was managed by myself and Brian Ford-Lloyd (see below). Another student, Ian Gubb, continued our work on the lack of enzymic blackening in Solanum hjertingii, a species from Mexico, in collaboration with the Food Research Institute in Norwich, where he grew his research materials under special quarantine licence. A couple of Peruvian students completed their degrees while working at CIP, so I had the opportunity of visiting CIP a couple of times while each was doing field work, and renew my contacts with former colleagues. In 1988, I was asked by CIP to join a panel for a three week review of a major seed production project at several locations around Peru.

With funding of the UK’s Overseas Development Administration (ODA, or whatever it was then), and now the Department for International Development (DFID), and in collaboration with the Plant Breeding Institute (PBI) in Cambridge and CIP, in 1983/84 we began an ambitious (and ultimately unsuccessful) project on true potato seed (TPS) using single seed descent (SSD) in diploid potatoes (having 24 chromosomes). Because of the potato quarantine situation at Birmingham, we established this TPS project at PBI, and over the first three years made sufficient progress for ODA to renew our grant for a second three year period.

We hit two snags, one biological, the other administrative/financial that led to us closing the project after five years. On reflection I also regret hiring the researcher we did. I’ve not had the same recruitment problem since.

Working with diploid potatoes was always going to be a challenge. They are self incompatible, meaning that the pollen from a flower ‘cannot’ fertilize the same flower. Nowadays mutant forms have been developed that overcome this incompatibility and it would be possible to undertake SSD as we envisaged. Eventually we hit a biological brick wall, and we decided the effort to pursue our goal would take more resources than we could muster. In addition, the PBI was privatized in 1987 and we had to relocate the project to Birmingham (another reason for handing over the Hawkes Collection to the CPC). We lost valuable research impetus in that move, building new facilities and the like. I think it was the right decision to pull the plug when we did, admit our lack of success, and move on.

We wrote about the philosophy and aims of this TPS project in 1984 [2], but I don’t have a copy of that publication. Later, in 1987, I wrote this review of TPS breeding [3].

Susan Juned

As I mentioned above, Brian Ford-Lloyd and I received a commercial grant to look into producing tissue-culture induced variants, or somaclones, of the crisping potato variety Record with reduced low temperature sweetening that leads to ‘blackened’ crisps (or chips in the USA) on frying. We hired Susan Juned as the researcher, and she eventually received her PhD in 1994 for this work. Since we kept the identity of each separate Record tuber from the outset of the project, over 150 tubers, and all the somaclone lines derived from each, we also showed that there were consequences for potato seed production and maintenance of healthy stocks as tissue cultures. We published that work in 1991. We also produced a few promising lines of Record for our commercial sponsor.

One funny aspect to this project is that we made it on to Page 3 of the tabloid newspaper The Sun, notorious in those days for a daily image of a well-endowed and naked young lady. Some journalist or other picked up a short research note in a university bulletin, and published an extremely short paragraph at the bottom of Page 3 (Crunch time for boffins) as if our project did not have a serious objective. In fact, I was even invited to go on the BBC breakfast show before I explained that the project had a serious objective. We weren’t just investigating ‘black bits in crisp packets’.

Brian and I (with a colleague, Martin Parry, in the Department of Geography) organized a workshop on climate change in 1989, when there was still a great deal of skepticism. We published a book in 1990 from that meeting (and followed up in 2013 with another).

Despite some successes while at Birmingham, and about to be promoted to Senior Lecturer, I had started to become disillusioned with academic life by the end of the 1980s, and began to look for new opportunities. That’s when I heard about a new position at IRRI in the Philippines: Head of the newly-established Genetic Resources Center, with responsibility for the world renowned and largest international rice genebank. I applied. The rest is history,

Klaus Lampe

I was appointed by Director General Klaus Lampe even though I’d never actually run a genebank before. Taking on a genebank as prestigious as the International Rice Genebank was rather daunting. But help was on the way.

I knew I had a good team of staff. All they needed was better direction to run a genebank efficiently, and bring the genebank’s operations up to a higher standard.

There was hardly an aspect of the operations that we didn’t overhaul. Not that I had the genebank team on my side from the outset. It took a few months for them to appreciate that my vision for the genebank was viable. Once on board, they took ownership of and responsibility for the individual operations while I kept an overview of the genebank’s operation as a whole.

With Pola de Guzman inside the Active Collection store room at +4C. Pola was my right hand in the genebank, and I asked her to take on the role of genebank manager, a position she holds to this day.

I’ve written extensively in this blog about the genebank and genetic resources of rice, and in this post I gave an overview of what we achieved.

You can find more detailed stories of the issues we faced with data management and germplasm characterization, or seed conservation and regeneration (in collaboration with my good friend Professor Richard Ellis of the University of Reading). We also set about making sure that germplasm from around Asia (and Africa and the Americas) was safe in genebanks and duplicated in the International Rice Genebank. We embarked on an ambitious five year project (funded by the Swiss government) to collect rice varieties mainly (and some wild samples as well), thereby increasing the size of the genebank collection by more than 25% to around 100,000 samples or accessions. The work in Laos was particularly productive.

We did a lot of training in data management and germplasm collecting, and successfully studied how farmers manage rice varieties (for in situ or on farm conservation) in the Philippines, Vietnam, and India.

One of IRRI’s main donors is the UK government through DFID. In the early 1990s, not long after I joined IRRI, DFID launched a new initiative known as ‘Holdback’ through which some of the funding that would, under normal circumstances, have gone directly to IRRI and its sister CGIAR centers was held back to encourage collaboration between dneters and scientists in the UK.

Whenever I returned on annual home leave, I would spend some time in the lab at Birmingham. John Newbury is on the far left, Parminder Virk is third from left, and Brian Ford-Lloyd on the right (next to me). One of my GRC staff, the late Amy Juliano spent a couple of months at Birmingham learning new molecular techniques. She is on the front row, fourth from right.

With my former colleagues at the University of Birmingham (Brian Ford-Lloyd, Dr John Newbury, and Dr Parminder Virk) and a group at the John Innes Centre in Norwich (the late Professor Mike Gale and Dr Glenn Bryan) we set about investigating how molecular markers (somewhat in their infancy back in the day) could be used describe diversity in the rice collection or identify duplicate accessions.

Not only was this successful, but we published some of the first research in plants showing the predictive value of molecular markers for quantitative traits. Dismissed at the time by some in the scientific community, the study of associations between molecular markers and traits is now mainstream.

In January 1993, I was elected Chair while attending my first meeting of the Inter-Center Working Group on Genetic Resources (ICWG-GR) in Ethiopia (my first foray into Africa), a forum bringing expertise in genetic conservation together among the CGIAR centers.

ICWG-GR meeting held at ILCA in Addis Ababa, Ethiopia in January 1993.

Over the next three years while I was Chair, the ICWG-GR managed a review of genetic resources in the CGIAR, and a review of center genebanks. We also set up the System-Wide Genetic Resources Program, that has now become the Genebank Platform.

I never expected to remain at IRRI as long as I did, almost nineteen years. I thought maybe ten years at most, and towards the end of the 1990s I began to look around for other opportunities.

Then, in early 2001, my career took another course, and I left genetic resources behind, so to speak, and moved into senior management at IRRI as Director for Program Planning and Coordination (later Communications, DPPC). And I stayed in that role until retiring from the institute ten years ago.

Ron Cantrell

The Director General, Ron Cantrell, asked me to beef up IRRI’s resource mobilization and project management. IRRI’s reputation with its donors had slipped. It wasn’t reporting adequately, or on time, on the various projects funded at the institute. Furthermore, management was not sure just what projects were being funded, by which donor, for what period, and what commitments had been set at the beginning of each. What an indictment!

I wrote about how DPPC came into being in this blog post. One of the first tasks was to align information about projects across the institute, particularly with the Finance Office. It wasn’t rocket science. We just gave every project (from concept paper to completion) a unique ID that had to be used by everyone. We also developed a corporate brand for our project reporting so that any donor could immediately recognise a report from IRRI.

So we set about developing a comprehensive project management system, restoring IRRI’s reputation in less than a year, and helping to increase the annual budget to around US$60 million. We also took on a role in risk management, performance appraisal, and the development of IRRI’s Medium Term Plans and its Strategy.

Bob Zeigler

Then under Ron’s successor, Bob Zeigler, DPPC went from strength to strength. Looking back on it, I think those nine years in DPPC were the most productive and satisfying of my whole career. In that senior management role I’d finally found my niche. There’s no doubt that the success of DPPC was due to the great team I brought together, particularly Corinta who I plucked out of the research program where she was working as a soil chemist.

Around 2005, after Bob became the DG, I also took on line management responsibility for a number of support units: Communication and Publications Services (CPS), Library and Documentation Services (LDS), Information Technology Service (ITS), and the Development Office (DO). Corinta took over day-to-day management of IRRI’s project portfolio.

With my unit heads, L-R: Gene Hettel (CPS), Mila Ramos (LDS), Marco van den Berg (ITS), Duncan Macintosh (DO), and Corinta Guerta (DPPC).

So, ten years on, what memories I have to keep my mind ticking over during these quiet days. When I began this post (which has turned out much longer than I ever anticipated) my aim was to decide between potatoes and rice. Having worked my way through forty years of wonderful experiences, I find I cannot choose one over the other. There’s no doubt however that I made a greater contribution to research and development during my rice days.

Nevertheless, I can’t help thinking about my South American potato days with great affection, and knowing that, given the chance, I’d be back up in the Andes at a moment’s notice. Potatoes are part of me, in a way that rice never became.

Everyone needs good mentors. I hope I was a good mentor to the folks who worked with me. I was fortunate to have had great mentors. I’ve already mentioned a number of the people who had an influence on my career.

I can’t finish this overview of my forty years in international agriculture and academia without mentioning five others: Joe Smartt (University of Southampton); Trevor Williams (University of Birmingham); Roger Rowe (CIP); John Niederhauser (1990 World Food Prize Laureate); and Ken Brown (CIP)

L-R: Joe Smartt, Trevor Williams, Roger Rowe, and John Niederhauser.

Joe, a lecturer in genetics, encouraged me to apply for the MSc Course at Birmingham in early 1970. I guess without his encouragement (and Jack Hawkes accepting me on to the course) I never would have embarked on a career in genetic conservation and international agriculture. I kept in regular touch with Joe until he passed away in 2013.
At Birmingham, Trevor supervised my MSc dissertation on lentils. He was an inspirational teacher who went on to become the Director General of the International Board for Plant Genetic Resources (IBPGR) in Rome. The last time I spoke with Trevor was in 2012 when he phoned me one evening to congratulate me on being awarded an OBE. He passed away in 2015.
Roger joined CIP in July 1973 as Head of the Breeding and Genetics Department, from the USDA Potato Collection in Wisconsin. He was my first boss in the CGIAR, and I learnt a lot from him about research and project management. We are still in touch.
John was an eminent plant pathologist whose work on late blight of potatoes in Mexico led to important discoveries about the pathogen and the nature of resistance in wild potato species. John and I worked closely from 1978 to set up PRECODEPA. He had one of the sharpest (and wittiest) minds I’ve come across. John passed away in 2005.
Ken Brown

Ken was a fantastic person to work with—he knew just how to manage people, was very supportive, and the last thing he ever tried to do was micromanage other people’s work. I learnt a great deal about program and people management from him.

Dr Richard L Sawyer (1921-2015), first Director General of the International Potato Center (CIP)

Sawyer3 I opened my email this morning to find one with the sad news that Richard Sawyer, the first Director General of the International Potato Center (CIP) had died at his home in North Carolina on 9 March. He was 93, just a week short of his 94th birthday.

Richard was my first boss from January 1973 when I joined the International Potato Center (CIP) as an associate taxonomist in Lima, Perú. In fact, Richard was one of the first Americans I had ever met, and it was quite an eye-opener, as a young British graduate, to be working for an organization led by an American.

I first met Richard in early summer 1971 or thereabouts, while I was a graduate student at the University of Birmingham. My major professor, and head of the Department of Botany at the university was renowned potato taxonomist Jack Hawkes. Jack had made a collecting expedition for wild potatoes to Bolivia in the first couple months of 1971. And his trip was supported by the USAID-funded North Carolina State University – Peru potato project. Richard had been in Lima since 1966 as head of that mission. I believe that Jack stayed in Lima with Richard and his wife, and had the opportunity to discuss with Richard how the recently-founded MSc course on Conservation and Utilization of Plant Genetic Resources could support the genetic resources activities at what would soon become the International Potato Center. Richard wanted to send a young Peruvian scientist (Zosimo Huaman) for training at Birmingham, but wondered if Jack had anyone in mind who could accept a one-year assignment in Peru while Zosimo was away in Birmingham studying for his MSc degree.

During a visit to meet with potential donors for the fledgling CIP in the UK, Richard came up to Birmingham from London to discuss some more about training possibilities, and the one-year assignment. And Jack invited me to meet Richard. I remember quite clearly entering Jack’s office, and my first impression of Richard Sawyer. “Good grief,” I thought to myself, “I’ve come to meet Uncle Sam!” At that time, Richard sported a goatee beard and, to my mind, was the spitting image of ‘Sam’.

I eventually moved to Lima in January 1973, and spent the next eight happy and scientifically fruitful years with CIP in Perú and Central America.

A family man. There are several things I remember specially about Richard. When I joined CIP he had recently remarried, and was devoted to his young wife Norma who was expecting their son Ricardo Jr. The Sawyers hosted a cocktail at their San Isidro apartment during that first week I was in Lima for the participants of a potato genetic resources and taxonomy planning workshop. Almost the whole staff of CIP had been invited – we were so few that everyone could easily fit into their apartment.

During that workshop we traveled to Huancayo to see the germplasm collection, and Richard drove one of the vehicles himself. Staying at the Turista hotel in the center of Huancayo, we spent that first night drinking pisco sours and playing dudo for a couple of hours.

Richard practiced what he preached. He was very supportive of CIP scientists and their families, and always encouraged his staff to maintain a healthy balance between work and home. At 4 pm each day he was the first out of the office and on to the frontón court; he was very competitive.

A TPS incident. I remember one (potentially disastrous) incident, in about 1978 or 1979, during the annual review meeting held in Lima, and in which all staff from around the world also participated. I came down to Lima from Costa Rica where I was leading CIP’s Region II Program (Mexico, Central America and the Caribbean). After several presentations about the emerging technology of true potato seed (TPS) during the first couple of days, the then Director of Research, Dr Ory Page from Canada, opened the floor for general comments and questions. I’d been storing up some comments and, nothing venture, nothing gained, stuck my hand up and began to make several critical comments about the TPS program and how it was not currently applicable to the farmers of Central America.

Well, as they say, the ‘proverbial’ hit the fan. Richard was seated immediately in front of me, among the CIP staff. He turned on me, and gave me a public dressing down. I decided not to accept this quietly, and responded as vigorously. As tempers began to fray, the Chair of the CIP Board Program Committee, British scientist Dr Glyn Burton, suspended the meeting. Richard stormed out to his office, followed by Dr Ken Brown, head of Regional Research and my immediate boss who was upset at Richard’s reaction. Several colleagues came up to me during the enforced break, and while they might have concurred with my point of view, felt that I had burned my bridges at CIP, and was likely to lose my job.

Far from it. A couple of days later, Richard came looking for me and apologized for how he’d behaved towards me; he told me that I’d had every right to question aspects of CIP’s research. I think this whole incident strengthened the relationship I had with Richard, and he was very supportive. It also indicated to me that Richard was a supremely confident person, and a strong leader.

Moving on. In 1980, a teaching position opened at the University of Birmingham. I was keen to apply, but felt I had to discuss the various options first. Ken Brown advised me to talk directly with Richard, and it was fortunate that I was already back in Lima, having left Costa Rica in November just before the Birmingham position was announced. Richard strongly encouraged me to apply for the Birmingham lectureship, but at the same time offering me a new five-year contract with CIP should I fail with my application. Now that was, as you can imagine, an unbelievable way to approach a job interview. I was offered the position and resigned from CIP in March 1981 to return to the UK.

But that wasn’t the end of my relationship with CIP. The UK Department for International Development (then the Overseas Development Institute) supported my research project with CIP on TPS of all things during the 1980s. And I also carried out a couple of consultancies for CIP, the more significant being an evaluation of a Swiss-funded seed potato project in Perú, during which I always had the opportunity to meet with Richard. He was always interested in what I was up to and how the family was getting on. After all, my wife Stephanie had also personally been offered a position at CIP by Richard from July 1973.

Richard’s legacy. There are so many things I could point out, but three come most readily to my mind:

Richard was a compassionate individual, very supportive of his staff and their families. But having a clear vision, he could also be determined and make the tough decisions. This served CIP extremely well during his tenure.
He placed the conservation of the germplasm collection and its use at the heart of CIP’s strategy and research. Later this was expanded to include sweet potatoes and several ‘minor’ Andean tuber crops. Focusing only on potato for the first decade enabled CIP to establish and maintain a strong research program, that had the strong foundation for expansion into other tuber crops.
His vision of regional research and collaboration with potato researchers around the world – and the use of CIP funding to support these scientists as part of CIP’s core research program – was not always appreciated around the CGIAR in the early 1970s. It was innovative, and CIP was able to have an early impact on and bring new technologies to potato programs and systems right around the world. The establishment of PRECODEPA in 1978 was one of these important initiatives. Not only did Richard persevere, but he showed that this model of collaboration was one applicable to other centers and their mandate crops. It is the modus operandi today.

It is always sad when a colleague and friend passes away. While we – his family, friends and former colleagues – mourn his passing, let us also celebrate a life of service to international agriculture by this extraordinary individual. It has been my privilege to count Richard Sawyer as a friend and mentor. My life has certainly been profoundly changed by knowing and working with him.

Deepest condolences to his wife Norma, son Ricardo Jr., his daughters from his first marriage, and all his family.

From a single potato tuber to one tonne in a year? Yes, it can be done.

After I’d completed my PhD in October 1975, I stayed on in the UK for a couple of months to sort out ideas and initial drafts for several journal papers, before returning to Lima, Peru just before the end of December, where I was to begin a post-doctoral fellowship with the International Potato Center (CIP). I’d already been working with CIP since January 1973 but I was uncertain in January 1976 where I was going to be located, or what my responsibilities would be. I had spent the previous three years working in CIP’s germplasm program, collecting native varieties of potatoes throughout the Peruvian Andes, and studied the evolution and ethnobotany of cultivated potato species (which formed the basis of the thesis I submitted to the University of Birmingham).

Moving to Costa Rica
CIP Director General Richard Sawyer asked me to move to Costa Rica in Central America to establish a research program on adaptation of potatoes to warm, humid environments, and also to participate in and support other regional activities from CIP’s regional office in Toluca, Mexico. Following a reconnaissance and feasibility mission with CIP colleagues Drs Roger Rowe (head of breeding and genetics) and Ed French (head of plant pathology) to Costa Rica in early January, my wife Steph and I moved to Turrialba in April to be based at CATIE (Centro Agronómico Tropical de Investigación y Enseñanza).

Those first few months were a wake-up call. Not only did I have to establish my own program, hire support staff (Leda Avila as secretary, Jorge Aguilar as research assistant, and Moisés Pereira as technician), and develop the facilities I might need, I also had to navigate rather carefully through the ‘politics’ of a host institution that felt – certainly at that time and for several years subsequently – very insecure. With its limited budget, CATIE management saw my assignment in Turrialba merely as a ‘cheap pair of hands’ to contribute to its research program on inter-cropping systems. I had a hard time convincing CATIE colleagues that, in the first instance, my research should focus on testing and identifying germplasm that showed broad adaptation and could be included in the broader systems research. I also had those other commitments outside Costa Rica that had to be managed as well.

Well, the long and short of it, was that we encountered a serious problem with bacterial wilt, caused by Ralstonia solanacearum, and from then, the focus of my research turned from warm environment adaptation to resistance studies and agronomic management.

Potatoes in Costa Rica during the 1970s
Bacterial wilt was also a serious problem for farmers in certain areas of the lower elevation production zones in Costa Rica. Potatoes have never been a major crop in Costa Rica (rice and beans are much more important staples), but on the slopes of the Irazú volcano near Cartago to the east and northeast of San José (the capital of Costa Rica), potato production is the main economic activity. In the mid- to late-1970s there were only about 10,000 ha of potatoes grown, and about 95% of the production was centered on this Cartago region. Within the Ministry of Agriculture there were only a couple of staff dedicated to potatoes, one agronomist and one pathologist. The small size of the Costa Rican potato program (and others in Central America) was the justification for developing the Regional Cooperative Potato Program (PRECODEPA) in 1978.

Two varieties of Mexican origin, Atzimba and Rosita, made up almost 100% of the production. Atzimba had been developed originally for its resistance to late blight, caused by Phytophthora infestans.

Potato fields of white-flowered var. Atzimba. Because of the steep slopes on the flanks of the Irazu volcano, farmers still use ox-drawn ploughs. These volcanic soils are very deep and fertile.

Mike Jackson using a motorized back-pack sprayer to fumigate potato seedlings in a virus resistance trial. Sprayers of this type produce a turbulent fine mist that effectively applies the pesticide. We were perhaps a little lax in terms of health and safety in the 70s!

In Costa Rica, however, it was extremely susceptible, because the climatic conditions permitted the cultivation of potatoes all year round somewhere in this rather restricted area on the flanks of the volcano. There was always fungal inoculum floating around, and farmers were often obliged to spray their crops at least once a week or more often. Believing that higher doses of fungicides would be more effective than the recommended dosage, the quantity of fungicide used was unacceptable. But it was difficult to persuade farmers to spray more effectively, to use machine powered back-pack sprayers rather than hand-pumped equipment that merely soaked the upper surfaces of the potato leaves. This is not very effective. The machine sprayers create a finer mist and also turbulence among the potato canopy and reach the undersides of the leaves where the fungus actually sporulates.

No healthy seed potatoes
As a vegetatively-propagated crop, potatoes are prone to the build up of several virus diseases that can, unless kept in check, result in a reduction of yield (or degeneration) year on year. That’s why in many countries there are seed production systems to provide potato farmers with healthy planting stock each year. Three common viruses were prevalent in Costa Rica: potato virus X (PVX), potato virus Y (PVY), and potato leafroll virus (PLRV) – singly, or more commonly, in combination, and as such were a serious threat to the long-term viability of national potato production. More so, it has to be said, than other pests and diseases that affected the crop that could be controlled – if applied effectively and safely – by a range of chemical treatments.

Costa Rica did not have a seed production program in the 1970s (and I haven’t been able to determine whether the foundations we at CIP laid in terms of seed production were maintained) even though many farmers did try to source their seed tubers from farms located at the highest elevations. Many farmers kept the smallest tubers from a commercial production or ware crop as ‘seed potatoes’ with the inevitable degeneration this practice brought with it. The main problem was that seed stocks were not being constantly being replenished with healthy tubers in a foundation seed initiative. The challenge was therefore to develop a seed production program that could effectively supply the seed potato needs of the country – several thousand tonnes annually.

Although healthy, virus-free stocks of Atzimba and Rosita were readily available, as well as bacterial wilt resistant varieties like MS-35-22 from tissue cultures initially but most often as a small number of virus-free tubers, how was it going to be possible to quickly multiply these seed stocks to a quantity that would begin to have some impact on potato yields in the short term?

The challenge
In 1979, CIP seed production specialist Jim Bryan joined me in Costa Rica on a one-year sabbatical to focus on the seed production needs of the Central American region. And together – with colleagues from the Ministerio de Agricultura y Ganadería – we developed a rapid multiplication program, not only to provide the foundation seed for Costa Rica, but also to put into practice many of the ideas that Jim had been developing at CIP headquarters in Peru, but which had not been tested in an actual production context. And at the same time we set ourselves a challenge: to produce one tonne of potatoes from a single tuber in a year (since the growing conditions in Costa Rica permitted more or less all-year-round production).

We converted our screen-houses in Turrialba full-time to this rapid multiplication project. We were sent a small quantity of basic seed tubers that had passed through tissue culture in Lima to eradicate viruses, or received actual tissue culture stocks that we grew on in a makeshift chamber at the plant pathology laboratory in the University of Costa Rica in San José, managed by my good friends and colleagues Drs Luis Carlos González Umaña (a bacteriologist with whom I collaborated over several years on bacterial wilt research) and virologist Rodrigo Gámez Lobo (who became the first director of the biodiversity institute, INBio).

But how to rapidly multiply limited seed stocks? Obviously we had to maintain the health of this basic seed, so only grew the tubers in pots inside the screen-house, in a ‘compost’ of sugarcane bagasse mixed with coarse river sand for better drainage. Having first sterilized this mixture, it was an excellent medium for growing potatoes in pots.

Once we had these plants established we could then start to take a whole range of cuttings: stem cuttings, single node cuttings (usually from young seedlings), sprout cuttings, and leaf-bud cuttings. Rooted cuttings could be grown on in the screen-house to produce more ‘mother plants’ or transplanted directly to the field. The same with single node cuttings and sprout cuttings. Leaf bud cuttings were made from senescing stems (or potato vines) and the axillary buds swelled to form a small tuber.

Each cutting was derived from an axillary bud, and these were stimulated to grow once the apical meristem had been removed from each stem. Cuttings were ‘planted’ in coarse river sand, kept constantly watered, and after a couple of weeks or thereabouts, most had produced healthy roots. Sometimes we used a rooting hormone, but mostly this was not necessary.

With the mixture of rooted cuttings planted directly in the field, plus the numerous tubers from cuttings in the screen-house, it was possible to produce hundreds of ‘daughter’ plants from each ‘mother’ plant that we grew only in the screen-house. And taken over a year, we did show that it was possible to produce one tonne of potatoes from a single tuber. Establishing a basic seed program based on the rapid multiplication of important varieties ensured that there was a constant replenishment of healthy seed available to farmers.

Spreading the word
Through PRECODEPA, we held several training courses in Turrialba on rapid multiplication techniques, and also produced a small brochure (in English and Spanish).

Storing seed tubers
Once we had harvested tubers from the screen-house – and for our other research projects – we had to have somewhere to store our seed stocks. At that time, my two colleagues from CIP headquarters in Lima, Dr Bob Booth and Mr Roy Shaw, had designed and promoted in many parts of the world low coast diffused light storage units. And based on their design, we built a prototype for warm humid conditions in Turrialba. It consisted of a double skin of corrugated fiberglass sheets, a wide overlapping roof to provide shade in the strong tropical sun, and an air conditioner to keep the temperature around 20C or so.

We placed bags of sand inside the store and kept them constantly wet, and therefore increased the humidity inside. We also monitored both the temperature and relative humidity as can be seen in one of the photos in the gallery below. Under these diffused light conditions, potato sprouts grow slowly and sturdy. certainly for our needs it was a viable and efficient option for potato storage.

Did we succeed?
I have no idea to what extent the seed production program prospered. One of the issues was commitment from the Ministry itself, but also the continuity of personnel in the potato program.

I left Costa Rica in November 1980 and returned to Lima, expecting to move to another CIP regional office early in 1981. The regional office in Los Baños, Philippines was mooted as a likely venue. As it turned out I resigned from CIP in March 1981 and joined the School of Biological Sciences – Department of Plant Biology at the University of Birmingham. Ten years later I did end up in Los Baños when I joined IRRI. But that’s another story.

Birmingham – a center for potato studies

When the late Professor Jack Hawkes was appointed to a lectureship in botany at the University of Birmingham in 1952, he had already been working on potatoes for more than a decade. And immediately prior to arriving in Birmingham he’d spent three years in Colombia helping to establish a national potato breeding program. From then until his retirement in 1982 – and indeed throughout the 1980s – Birmingham was an important center for potato studies.

The potato germplasm that Hawkes collected (with EK Balls and W Gourlay in the 1938-39 expedition to South America) eventually formed the basis of the Empire then Commonwealth Potato Collection, maintained at the James Hutton Institute in Scotland. Throughout the 50s, 60s, 70s, and 80s Jack also had a large collection of wild potato (Solanum) species at Birmingham. This was a special quarantine collection; in the 1980s for potato quarantine purposes, Birmingham was effectively outside the European Union! For more than two decades Jack was assisted by horticultural technician Dave Downing, seen in the photo below. At the end of the 1980s we decided to donate the seed stocks from Jack’s collection to the Commonwealth Potato Collection, and it went into quarantine in Scotland. As the various lines were tested for viruses diseases they were introduced into the main collection. Jack used this collection to train a succession of PhD students on the biosystematics of potatoes. I continued with this tradition after I joined the University of Birmingham in 1981. My first student graduated in 1982 (after I had taken over supervision from Jack).

Here is the list of University of Birmingham PhD students who worked on potatoes, as far as I can remember. All of them from 1975 (with the exception of Ian Gubb) had also attended the MSc course on genetic resources:

Richard Lester (UK), 1962. Taught at Makerere University in Uganda, before joining the Dept. of Botany at Birmingham in 1969. Retired in 2002, and died in 2006. Studied the biochemical systematics of Mexican wild Solanum species. The species Solanum lesteri is named after him.

Richard Tarn (UK), 1967. Emigrated to Canada in 1968, and joined Agriculture Canada as a potato breeder in Fredericton, New Brunswick. Retired in 2008. Studied the origin of ploidy levels in wild species.

Katsuo Armando Okada (Argentina), 1970 (?). Retired. Was with IBPGR for a while in the 1980s (?) in Colombia. Studied the origin of Solanum x rechei from Argentina.

Phillip Cribb (UK), 1972. He joined the Royal Botanic Gardens – Kew, and became a renowned orchid taxonomist. Studied the origin of the tetraploid Solanum tuberosum ssp. andigena.

Mike Jackson (UK), 1975. Studied the triploid cultigen Solanum x chaucha. Joint with CIP and Roger Rowe.

David Astley (UK), 1975. Became the curator of the vegetable genebank at Wellesbourne (now the Warwick Crop Centre). Studied the Bolivian wild species Solanum sucrense. The species S. astleyi is named after Dave.

Zosimo Huaman (Peru), 1976. He returned to the International Potato Center (CIP) in Lima, and continued working with the germplasm collection until December 2000; he then began work with several NGOs on biodiversity issues in Peru. Studied the origin of the diploid cultigen Solanum x ajanhuiri. Joint with CIP and Roger Rowe.

Peter Schmiediche (Germany), 1977. He continued working with CIP as a potato breeder (for resistance to bacterial wilt), and was later CIP’s regional leader based in Indonesia. Now retired and sharing his time between Texas (where his children settled) and his native Berlin. Studied the bitter potatoes Solanum x juzepczukii (3x) and S. x curtilobum (5x). Joint with CIP and Roger Rowe.

Luis Lopez (Colombia), 1979. Studied wild species in the Series Conicibaccata.

Lenny Taylor (UK), late 1970s. I don’t remember his thesis topic, but I think it had something to do with tetraploid forms. He joined the Potato Marketing Board (now the Potato Council) but I’ve lost contact.

Lynne Woodwards (UK), 1982. Studied the Mexican tetraploid Solanum hjertingii, which does not show enzymic blackening in cut tubers.

Rene Chavez (Peru), 1984. He returned to the University of Tacna, Peru, but also spent time at CIAT in Cali, Colombia studying a large wild cassava (Manihot spp.) collection. He sadly died of cancer a couple of years ago. Studied wide crossing to transfer resistance to tuber moth and potato cyst nematode. Joint with CIP and Peter Schmiediche.

Elizabeth Newton (UK), 1987? Studied sexually-transmitted viruses in potato. Joint with former CIP virologist Roger Jones (now at the University of Western Australia) at the MAFF Harpenden Laboratory.

Denise Clugston (UK), 1988. Studied embryo rescue and protoplast fusion to use wild species in potato breeding.

Carlos Arbizu (Peru), 1990. An expert on minor Andean tuber crops, he came from the University of Ayacucho. Spent time working in the germplasm program at CIP. Studied the origin and value of resistance to spindle tuber viroid in Solanum acaule. Joint with CIP and principal virologist Luis Salazar (who gained his PhD while studying at the Scottish Crop Research Institute in Dundee).

Ian Gubb (UK), 1991. Studied the biochemical basis of non-blackening in Solanum hjertingii. Joint with the Food Research Institute, Norwich.

Susan Juned (UK), 1994. Now a sustainable technology consultant, Sue is an active local government councillor, and has stood for election to parliament on a couple of occasions for the Liberal Democrats. Studied somaclonal variation in potato cv. Record; this commercial contract research was commissioned by United Biscuits.

David Tay (Malaysia), 2000. He worked in Australia and then was Director of the USDA Ornamental Plant Germplasm Center in Columbus, Ohio, but returned to CIP as head of the genetic resources unit in 2007. He’s now left CIP. I think he worked on diploid cultivated species. Joint with CIP. Not sure why his PhD is dated 2000, as he’d been in CIP in the late 70s.

I also supervised several MSc students who completed dissertations on potatoes (Reiner Freund from Germany, and Beatrice Male-Kayiwa and Nelson Wanyera from Uganda).

The Birmingham link with CIP is rather interesting. In the early 70s, staff at CIP seemed to have a graduate degree in the main from one of four universities: Cornell, North Carolina State, Wisconsin, or Birmingham.

Besides the Birmingham PhD students who went on to work at CIP, my wife Stephanie (MSc 1972, who had been working with the Commonwealth Potato Collection from November 1972 – June 1973 when it was still based at the Scottish Plant Breeding Station – now closed) joined the Breeding and Genetics Dept. at CIP in July 1973.

Roger Rowe, who had been in charge of the US potato genebank in Sturgeon Bay, Wisconsin, also joined CIP in July 1973 as head of the Breeding and Genetics Dept. He co-supervised (with Jack Hawkes) a number of Birmingham PhD students.

With the closure of Jack’s collection at Birmingham we were able to develop other potato research ideas since there were no longer any quarantine restrictions. In 1984 we secured funding from the Overseas Development Administration (now the Department for International Development – DfID) to work on single seed descent (SSD) from diploid potatoes to produce true potato seed (TPS). Diploids are normally self-incompatible, but evidence from a range of species had shown that such incompatibility could be broken and transgressive segregants selected. The work was originally started in collaboration with the Plant Breeding Institute (PBI) in Cambridge, but when the Thatcher government privatized the PBI and sold it to Monsanto in 1988, we continued the work at Birmingham. After a further year we hit a ‘biological brick wall’ and decided that the resources needed would be too great to warrant continued effort. This paper reflects our philosophy on TPS [1]. Another paper [2] spells out the approach we planned.

Potatoes – the real treasure of the Incas . . .

Home of the potato
The Andes of South America are the home of the potato that has supported indigenous civilizations for thousands of years. As many as 4,000 native potato varieties are still grown. The region around Lake Titicaca in southern Peru and northern Bolivia is particularly rich in genetic diversity, and the wild potatoes from here are valuable for their disease and pest resistance [1].

For three years, from 1973-1975 I had the privilege of living and working in Peru (fulfilling an ambition I’d had since I was a boy) and studying the potato in its homeland. My work took me all over the mountains to collect potato varieties (for conservation in the germplasm collection of the International Potato Center (CIP), and to carry out studies of potato cultivation that I hoped would throw some light on different aspects of potato evolution [2].

I joined CIP in January 1973 as Associate Taxonomist, charged with the task of collecting potato varieties and helping them to maintain the large germplasm collection, that grew to at least 15,000 separate entries (or clonal accessions), but was reduced to a more manageable number through the elimination of duplicate samples. The germplasm collection was planted each year from October through April, coinciding with the most abundant rains, in the field in Huancayo, central Peru at an altitude of more than 3,100 meters.

When CIP was founded in 1971, several germplasm collections from various institutes in Peru and elsewhere were donated to the new collection, but from 1973 CIP organized a program of collecting throughout Peru – and I was fortunate to be part of that endeavour. In May 1973 I joined my colleague Zosimo Huaman to collect potatoes in the Departments of Ancash and La Libertad, to the north of Lima. The highest mountains in Peru are found in Ancash, and our route took us through into the Callejón de Huaylas (between two ranges of the highest mountains in Peru, the Cordillera Blanca on the east, and Cordillera Negra on the west), and over the mountains to valleys on the eastern flanks. This was my first experience of collecting germplasm, and it was exhilarating. I think we did quite well in terms of the varieties collected, and the photograph below illustrates some of their immense genetic diversity.

Genetic diversity in cultivated potatoes

The following year I traveled with just a driver, Octavio (who was unfortunately killed in a road accident a couple of years later) further north into the Department of Cajamarca during April-May 1974. The photograph below shows the view, in the early morning sun, south towards Cajamarca city. The mist hanging over the city comes from hot springs that were utilized centuries ago by the Incas to build bath houses.

We collected potatoes in the field at the time of harvest, but also in markets (here is shown the market of Bambamarca), and from farmers’ own potato stores. Incidentally, the tall straw hats are very typical Cajamarca, as are the russet-colored ponchos.

MTJ collecting cultivated potatoes in 1974

In January 1974 I made a trip south, with Dr Peter Gibbs, a taxonomist from the University of St Andrews, Scotland, who was interested in the tri-styly pollination of a minor Andean tuber crop called oca (Oxalis tuberosa). We went to the village of Cuyo Cuyo, more than 100 km north of Puno in southern Peru. Dropping down from the altiplano, the road hugs the sides of the valley, and is often blocked by landslides (a very common occurrence throughout Peru in the rainy season). Along the way – and due to the warmer air rising from the selva (jungle) to the east – the vegetation is quite luxurious in places, as the white begonia below shows (the flowers were about 8 cm in diameter). Eventually the valley opens out, with terraces on all sides. These terraces (or andenes) are ancient structures constructed by the Incas to make the valley more productive.

In Cuyo Cuyo, I studied the varieties growing in farmers’ fields, and their uses [3].

Getting to some locations by four-wheel drive vehicle was often difficult. Then it was either ‘shanks’ pony’, or real pony. I do remember that I became very sore after many hours in the saddle. Incidentally, I still have that straw hat and it’s as good as the day I bought it in January 1973.

But studying potato systems, and working with farmers was fascinating. Here I am collecting flower buds, and preserving them in alcohol ready to make chromosome counts in the laboratory, back in Lima.

The next photograph shows a community we visited close to Chincheros, near Cuzco in southern Peru. While farmers grew commercial varieties to send to market in Cuzco – the large plantings of potatoes in the distance -closer to their dwellings they grew complex mixtures of varieties, with different cooking and eating qualities.

Most farmers do not have access to mechanization, apart from manual labor and oxen to pull ploughs. In any case, much of the land in these steep valleys is unsuitable for mechanization. For centuries, farmers use the chakitaqlla or foot plough illustrated by Peruvian chronicler Felipe Guaman Poma de Ayala in the early 17th century. There are many different foot ploughs in used throughout Peru. The foot plough shown below in one of Poma de Ayala’s illustrations is the same as that used by farmers in Cuyo Cuyo. The photograph underneath shows farmers near Huanuco in central Peru.

I never collected wild potatoes as such, but it was fun on two occasions to accompany my thesis supervisor and mentor, Jack Hawkes (a world-renowned expert on the taxonomy and evolution of potatoes, and one of the founders of the genetic resources movement in the 1960s) on short trips. In January 1973 we visited Cuzco, and Jack found Solanum raphanifolium growing among the ruins of the Inca fortress of Sacsayhuaman.

Sacsayhuaman at Cuzco

Early 1975 (during one of his annual trips to CIP) Jack, Juan Landeo (then a research assistant, who later became one of CIP’s potato breeders), and I traveled over four days through the central Andes just north and east of Lima, in the Departments of Cerro de Pasco, Huanuco, and Lima. It was fascinating watching an expert at work, especially someone so familiar with the wild potatoes and their ecology. We’d be driving along, and suddenly Jack would say “Stop the car! I can smell potatoes”. And more than nine times out of ten we’d find clumps of wild potatoes after just a few minutes of searching. Here we are (looking rather younger) about to make a herbarium collection just south of Cerro de Pasco (I don’t remember which wild species, however).

Markets are always fascinating places to collect germplasm of many different crops. The next two photographs show colorful diversity in maize and peppers.

Among the many you can find in the market is chuño, a type of freeze-dried potato, made from several varieties of so-called bitter potatoes, which have a high concentration of alkaloids which must be removed before eating. This is done by first leaving the tubers on the ground on frosty nights to freeze, and then thaw the following morning. After several cycles of freezing and thawing the tubers are then soaked for several weeks in fast-flowing streams to leach out the bitter compounds. Afterwards, they are left to dry in the sun, and in this preserved state will last for months. This photograph was taken in the Sunday market at Pisac, near Cuzco.

Clearly the potato is an ancient crop in Peru (and other countries of the South American Andes), and domesticated several thousand years ago. It was revered by ancient civilizations, as these anthropomorphic potato pots (or huacos) show. The national anthropological museum in Lima has a fine collection of these pots showing a vast array of different crop plants. It also holds an extensive collection of erotic ceramics for which the Incas, Moche, and other coastal civilizations were equally famous.

After the conquest of the Incan empire by Francisco Pizarro González in the 16th century, the Spanish plundered all the gold and other precious items they could find, and sent everything back to Spain. It’s often said, however, that the value of all this gold fades into insignificance compared to the value of the potato crop today worldwide. The real treasure of the Incas has certainly been put to better use.

Memories of Russian geneticist Nikolai Ivanovich Vavilov (1887-1943)

A recent article brought to mind what I learned about Nikolai Ivanovich Vavilov (left) when I was a student, and also conversations I had with two eminent scientists who actually met Vavilov in Leningrad more than 80 years ago.

Vavilov was a brilliant geneticist, whose story the whole world deserves to know. The Crop Trust has just launched a new web series, Seed Heroes, with this first story, Nikolai Vavilov: The Father of Genebanks.

Surprisingly, as an undergraduate student studying botany in the late 1960s, I never heard anything about Vavilov or his pioneering work. In retrospect, I’m of the firm opinion that he should be part of every plant sciences or genetics degree curriculum. He was such a colossus, and one of my science heroes, about whom I have written or referred to in many blog posts.

It was only when I began a one-year MSc course on the Conservation and Utilization of Plant Genetic Resources at the University of Birmingham in September 1970 that I became acquainted with Vavilov and what he achieved to collect and study different varieties of crop plants from more than 100 countries. All with the aim of using the varieties—or genetic resources as we now can describe them—to breed new crops and make Soviet agriculture more resilient. Indeed, Vavilov is often referred to as the father of plant genetic resources, and correctly so, nevermind father of genebanks.

Vavilov was highly respected in the West, and he visited the UK spending time in the early years of the last century at the John Innes Horticultural Institution near London. His study of crop variation also opened new perspectives on the nature and distribution of genetic diversity in crop plants and their wild relatives, and where crops were domesticated thousands of years ago.

What would Vavilov have gone on to achieve had he not fallen foul of Stalin’s Soviet regime and his nemesis, Trofim Denisovich Lysenko, dying of starvation in prison in Saratov in 1943 at the age of 55?

So, what was Vavilov like as a man and scientist? Having spoken at length with Professor Jack Hawkes and Dr John Niederhauser about their visits to Russia in the 1930s, and meeting Vavilov, I almost feel that I knew him myself, albeit vicariously.

Jack Hawkes (right, 1915-2007), a potato taxonomist and head of the Department of Botany at the University of Birmingham founded the genetic resources MSc course there in 1969. Jack was also the co-supervisor (with Dr Roger Rowe of the International Potato Center in Peru) of my PhD research and dissertation.

In 1937, having just graduated from the University of Cambridge, Jack applied for an assistant’s position to join Dr PS Hudson, Director of the Imperial Bureau of Plant Breeding and Genetics in Cambridge, on an expedition to Lake Titicaca in the South American Andes to collect wild and cultivated potatoes. That expedition was delayed, and it wasn’t until early January 1939, under a new expedition leader, that Jack finally found himself in South America. The germplasm that was collected—from Argentina in the south to Venezuela in the north of the continent—became the founding accessions of what is now known as the Commonwealth Potato Collection.

You can read all about the Empire Potato Collecting Expedition to South America on this website (and view films that Jack made more than 80 years ago) based on Jack’s expedition notes and a 2003 memoir of the expedition, which he titled Hunting the Wild Potato in the South American Andes.

In Chapter 1 of that memoir, Jack describes at length the two week visit he made to Russia to meet with potato experts SM Bukasov, VS Juzepczuk, and VS Lechnovicz, to understand more about potato diversity (he’d never worked on potatoes until then), and discuss where and when to collect in South America since the Russians had already made collections there.

Jack writes that the visit to Leningrad was an experience that changed [his] life in many ways. He never forgot the kindness shown to him, a young man of only 23, by Vavilov and his colleagues.

Arriving in Leningrad on 26 August (or thereabouts), he first met Professor Bukasov, and almost immediately that same afternoon he was taken to the Lenin Academy of Sciences to meet Vavilov. Jack was invited to Vavilov’s apartment in Leningrad and his house in Moscow. They visited research stations together, and Vavilov even took Jack to the opera in Leningrad.

They discussed Vavilov’s ideas on the origin of crop plants and his theory of centers of diversity, his ‘Law of Homologous Series’ (which I applied in a paper on potatoes I presented at a Vavilov Centenary Symposium in 1987), the Russian system of potato taxonomy (which Jack initially used but found it over-complicated), and comparisons of British and Soviet agriculture.

They couldn’t avoid discussing Lysenko and his strong rejection of Mendelian genetics. Vavilov acknowledged Lysenko’s good work on wheat vernalization, and did not seem upset at Lysenko’s rejection of [Vavilov’s] results. Inevitably Jack and Lysenko crossed paths. Jack found him a dangerous, bigoted personality, entirely wrapped up in his own ideas. He was a . . . wholly repellent person. He was a politician rather than a scientist, and very much able to ingratiate himself with the communist politicians in Moscow. Here was, they thought, a Soviet man, born an unlettered peasant and now the sort of “first class” scientist that the communist system had created.

By 1938, Lysenko was in the ascendance, and obtaining more money for his work than Vavilov. In 1940, Vavilov was arrested and sent to prison on a trumped-up charge, and died there three years later, apparently of starvation. Ironic really, given that Vavilov had devoted his life to making agriculture more sustainable and increase crop productivity with the aim of defeating famine.

After he retired from Birmingham in 1982 (I had been appointed lecturer in plant biology the year before), Jack and I would often meet for lunch and a beer, and he would tell me all about that visit to Russia and meeting Vavilov. He said it had been a great experience, and still couldn’t quite believe that Vavilov, a world-famous scientist, had treated him, a young man embarking on his scientific adventure, as an honored guest.

Jack’s lasting impression of Vavilov (who he admired immensely) more than 60 years later was a large, jovial, hospitable and friendly person, putting [Jack] at ease and talking to [him] as an equal about his work and that of his colleagues.

I first met John Niederhauser (left, 1916-2005) in the early 1970s when I was an Associate Taxonomist at the recently-founded International Potato Center (CIP) in Lima, Peru and he was a consultant/advisor to CIP’s Director General, Dr Richard Sawyer.

John was the 1990 World Food Prize Laureate. A plant pathologist, he spent much of his career as a member of the Rockefeller Foundation’s agriculture program in Mexico (where his colleague in the wheat program was Norman Borlaug, the Nobel Peace Laureate in 1970), and researching resistance to the late blight pathogen of potatoes, Phytophthora infestans, the cause of the Irish Potato Famine of the 1840s.

In 1976, I had moved to Costa Rica and by 1977 I had been appointed CIP’s regional representative covering Mexico, Central America, and the Caribbean. About then, John’s and my paths crossed again, and we worked closely together for a year to design and launch a regional potato program, PRECODEPA, in six countries (later expanded to several more countries, and funded by the Swiss government for at least 25 years).

John and I traveled frequently together to those initial six countries, spending hours in airports and on the various flights, so had ample opportunity to really get to know one another.

He had been brought up on a farm in Washington state, but at the age of 17 in 1934 he bought himself a ticket to travel to Russia (I subsequently learned he had relatives there). So why choose Russia? Well, as John recounted the story, he had gone to a travel agent in San Francisco, and asked how far he could travel on his available funds. A return ticket to Leningrad was the outcome.

It seems that he and Vavilov met quite by chance. John had been visiting a botanical garden in Moscow, when a gentleman stopped and asked (in English) who he was and where he had come from. It was Nikolai Vavilov, of course. Well, the outcome (based apparently in part on John’s self-declared knowledge of tractor mechanics) was that Vavilov offered him a summer job on a state farm in the Ukraine where important germplasm collections were being multiplied. I’ve subsequently learnt that John spent an academic year in Moscow, all at the behest of Vavilov, before moving to Cornell University, where he also obtained his PhD in 1943 (the year of Vavilov’s death).

And like Jack Hawkes, John was full of admiration for Vavilov. He said that meeting him had changed the course of his life.

In the field of conservation and use of plant genetic resources, Vavilov is a giant. His scientific ideas about crop diversity have mainly stood the test of time. The collections he made are still held in the genebank that now bears his name. And his descriptions of crop diversity (I’ll never forget those of the rosaceous tree fruit forests—apples, pears and the like—in the mountain foothills of Kazakhstan), have inspired later generations of germplasm scientists, me in particular. As an MSc student, I wrote a dissertation on the origin of lentils, Lens culinaris. One of the major publications I had to consult was a monograph by Russian scientist Elena Barulina, Vavilov’s second wife.

Again I find myself wondering just what else Vavilov might have achieved had the Soviet regime never persecuted him so cruelly.

That was the year that was . . .

Let me begin this round-up of my 2023 blogging activity by wishing all my readers A Happy and Prosperous New Year 2024.

When I began thinking about this end-of-year post, it seemed to me that I’d been much less active on my blog during 2023 than in previous years. However, when I checked the stats, I saw that this is post number 45 for the year (compared with 43 in 2021 and 42 last year), and a slightly higher number of words overall.

There was, however, a particular blog milestone back in mid-August: my 700th post since I began in February 2012.

So why did I have this impression about my blog productivity this year?

Throughout 2023, I’ve had this constant feeling that Steph and I just didn’t do so much this past year compared to previous ones. That’s partly due to the fact that from the beginning of March (until quite recently) my mobility has been seriously constrained by lower back and leg pains, caused by spinal stenosis (that was finally diagnosed in August after an MRI scan). In recent weeks, things have improved compared to earlier in the year, but I still need to take daily pain medication and I have a regime of exercises first thing in the morning. It meant that for several months I just wasn’t able to get out and about on my daily walk or, if I did, just a short shuffle close to home.

Then, in July and August in particular, the weather here in the UK was particularly wet, and it hasn’t been much better ever since. So whenever we saw a break in the weather we tried to make an excursion somewhere: to some of the magnificent beaches on the Northumberland coast or inland to explore the awe-inspiring Northumberland landscapes. But those days have been few and far between.

Chew Green, a Roman fort in the Cheviot Hills, close to the border with Scotland.

But we have enjoyed our visits to The Alnwick Garden (where we have Friend of the Garden membership) every few weeks, to enjoy a coffee in the excellent cafe there before making a tour (lasting about an hour) around the garden. It’s always a pleasure to see the Garden in its different moods throughout the seasons.

And then it’s on to the coast or inland for one of our favorite views over the Northumberland landscape. We are so lucky to live close to the North Sea coast and its awesome beaches, such as this one at Cresswell.

Mid-year we spent three weeks in the USA, visiting our elder daughter Hannah and her family in Minnesota.

This was our first overseas trip since 2019. The Covid pandemic prevented us traveling to the USA in 2020 and 2021. In 2022 we still felt somewhat uncomfortable about air travel, so Hannah and family came over to the UK.

Then in September, we spent a week in North Wales, enjoying the landscapes that neither I nor Steph had explored since we were children. Staying in a farm cottage just south of Caernarfon we visited several National Trust properties such as Bodnant Garden and Penrhyn Castle, as well as Edward I’s 12th century castles owned by Cadw, the Welsh heritage organization (equivalent to English Heritage).

Caernarfon Castle

All in all, a great week away with much better than expected weather, which deteriorated quite rapidly thereafter. At the end of September, Storm Agnes barreled in off the Atlantic, and there have been six since then named jointly by UK Met Office, Met Éireann and the Dutch National Weather Service (KNMI). And just these past days, Storm Gerrit (following on almost immediately after Storm Pia that had been named by the Danish Met Service) caused major disruption across the country (especially in Scotland), including a tornado in the Manchester area.

If you browse through my posts for 2023 you will see they cover a whole range of topics — just as the name, A Balanced Diet, of my blog suggests. Obviously there were several posts about our Minnesota visits, and the holiday in North Wales. But often something in the news catches my eye, and inspires me to write something. Like the time I shared my thoughts about proposed changes to England’s education system and the introduction of a broader curriculum. Or the post I wrote about bridges after reading about someone inspired by these awesome constructions. Then Steph and I celebrated our 50th wedding anniversary in October and I turned 75 in November. Two more stories there.

For several years now, I haven’t commented on politics or the state of the world as I see it. But 2023 has been an extraordinary year, both nationally and internationally, for all the wrong reasons, that I feel I cannot end the year without making some comments.

In the UK, the Tory government (if you can call it that) lurches from one catastrophe to another. The dismissal and appointment of Cabinet members has seemed like a game of musical chairs. Fortunately, the ever cruel Suella Braverman has gone from the Home Office but her decidedly far right agenda with regard to immigration (legal or illegal) still pervades the Tories.

Rishi Sunak (or Rish! Pipsqueak as I prefer to refer to him) is a weak, arrogant, and inept Prime Minister, who has been found wanting in several areas. His appearance before the Covid Inquiry didn’t help his image. And where did all those WhatsApp messages go?

Former Prime Minister Boris Johnson’s appearance before the same inquiry just confirmed what we already knew about this self-serving, narcissistic liar.

Hopefully, there will be a General Election before long (there must be one by the end of 2024), and Labour will sweep to power with an overwhelming majority. That’s if the polls are to be believed.

I can’t say I have too much faith in Labour leader Sir Keir Starmer, but he should be a damn sight better as Prime Minister than the present incumbent (or immediate predecessors). However, I fear that the Tories will engineer the nation’s finances in such a way to leave Labour with a toxic legacy to deal with. For the Tories it’s definitely ‘Party before Country’.

Over in the United States, it’s hard to believe that Donald Trump has a good chance of winning back the White House in 2024. I was amazed (and equally appalled) when Trump won in 2016, but to think that he can make a comeback after all he has been accused of (and indicted for) beggars belief. The MAGA Republicans are no better than a Trump cult.

But the Democrats have their own problems. While the country has prospered under Joe Biden (who has kept quite a low profile compared to Trump when in office), does it really make sense for an octogenarian (he’ll be almost 82) to contest this general election? But who to take his place?

The outrageous invasion of Ukraine by Russia has slipped somewhat from the headlines in recent months, but every day still brings news of Russian aggression against civilians, with a flare-up just over the past couple of days. Day 676! Can it really be almost two years since the war began, and remaining stalemated to some extent? The prognosis for 2024 is not optimistic.

I have hesitated to make any public comments about the current situation in the Middle East, concerned that anything I might add would be construed as being anti-semitic. But read this from political commentator here in the UK, Robert Peston.

What Hamas perpetrated against innocent Israeli civilians on 7 October was beyond abhorrent, and bound to trigger a military response. But has Israel’s response been proportionate?

What the Israeli government and the Israel Defence Force have subsequently have inflicted upon millions of innocent Palestinian civilians in Gaza, and thousands of deaths (many of whom were women and children) is equally abhorrent, if not more so. And Israeli aggression continues in the occupied West Bank, where illegal settlements continue to spread, and settlers continue their attacks on Palestinians, supported by the Israeli government. What a depressing circle of violence.

And don’t get me started on climate change . . .

‘Teaching is the one profession that creates all other professions.’ (Unknown)

I was surprised recently to read a tweet (or whatever they’re now called) on X suggesting that all university lecturers should be required to receive formal teacher training and an appropriate qualification. Just as teachers of schoolchildren must complete the Postgraduate Certificate in Education (or PGCE). Not that the PGCE automatically makes everyone a good teacher. Far from it. But the training must surely provide or hone the skills needed to teach better.

Well, whoever it was who tweeted that comment is behind the times. Many (most/all?) universities here in the UK now require incoming, probationary staff at least to take courses, such as the Postgraduate Certificate in Higher Education (PGCHE, a Masters level qualification) and also offer various teaching support modules to more established staff, that cover topics such as small/large group teaching, curriculum design, supervision, and many more.

But when I joined the University of Birmingham as a lecturer in the Department of Plant Biology (School of Biological Sciences) in April 1981 there was no such requirement for teacher training, nor do I remember much if any support being provided. You simply got on with it – for better or worse. Furthermore, teaching loads or commitments, or ability never counted much towards promotion prospects. Research (and research income) was the be-all and end-all.

I’d never aspired to be an academic. Before joining the university, I was working in the Americas over the previous eight years. In November 1980, I had just returned from a five-year assignment in Central America to the headquarters of the International Potato Center (CIP) in Lima, Peru while waiting for my next assignment in the Philippines. I had, however, already applied to Birmingham.

In January 1981 I flew to the UK for an interview and was offered the position immediately. So I returned to Lima knowing that my wife Steph and young daughter Hannah and I would be resettling in the UK before long.

Initially I had no teaching commitments, and I was able to get myself settled and oriented as a faculty member. I knew my way around the Birmingham campus since I was awarded my MSc degree in genetic resources there in 1971, and PhD in botany in 1975. But being a faculty member was very different from being a graduate student.

Come the beginning of the Summer Term in May however, I found myself facing a group of about 35 second year plant biology students for the first time to teach them some aspects of flowering plant taxonomy (along with my colleague Dr Richard Lester, at right, with whom I didn’t always see eye-to-eye over many aspects of course content and delivery).

Anyway, until then I had never taught a class in my life, although I was quite comfortable with public speaking, even enjoying it. I think I must have inherited my ‘love’ of public speaking from my father. Anyway, getting up in front of an audience never particularly fazed me, talking to my peers about my work, and the like. Nevertheless, I always had ‘butterflies in my stomach’ before facing a class for the first time.

Fortunately during the decade I spent at Birmingham I never had to teach any first year classes. Much of my teaching focused on graduate students (many from overseas) attending the 1-year MSc course on Conservation and Utilisation of Plant Genetic Resources (the very course I had attended in 1970-71). I taught a semester long (10 week term) course on crop evolution, two lectures and three hour practical classes per week, principles of germplasm exploration and collection (also with a practical component using a synthetic population made up of many different barley varieties), and a small module on agroecosystems. I also helped my colleague Professor Brian Ford-Lloyd (right) in some aspects of his data management module.

Then, during the summer months (when undergraduates were on vacation) we would supervise the dissertation projects of the MSc students. I guess I must have averaged two or three each year.

Brian and I jointly taught a five week undergraduate course on plant genetic resources, with at least one lecture per day, for final year undergraduates who would graduate with a Biological Sciences (Plant Biology) degree. I guess we must have between 10 and 15 students on average each year, who also had to complete an independent research project over the same period. It was always a challenge to devise projects that could be completed in the time available and that would (generally) generate positive results. Each student would take four of these five week modules.

I also gave a lecture on potato diseases on the third year plant pathology module taught by my colleague Dr Gillian Butler.

Around the mid-1980s I was asked to become chair of the Second Year Common Course, one that all biological sciences students had to take and which was taught by staff from all the four departments (Plant Biology, Zoology and Comparative Physiology, Genetics, and Microbiology) that made up the School of Biological Sciences. I contributed five or six lectures on agriculture and agroecosystems, based on my own experiences of working with crops in the Americas.

To some extent I agree with American novelist Gail Godwin that Good teaching is 1/4 preparation and 3/4 theatre. When you get up in front of a class of students, whether you feel up to it or not, whether it’s a topic you are enthusiastic or not, you have to ‘perform‘. Engage with the class.

The feedback I had from my students was that I was quite an effective teacher. That was gratifying to know. Back in the day, there was no Powerpoint or other digital props. Just the blackboard and chalk (which I hated as I had a slight allergy to chalk), the overhead projector with acetates, and 35 mm slides.

The tools which are available today permit a much more dynamic use of information, provided that there isn’t information overload. Less is often more. And you don’t try to use all 56 million colours in the Powerpoint pallette (as I have seen some speakers attempt to do!).

I think I became a more effective because I had to teach many graduate students who did not have English as their first language. We worked closely with a unit in the English department who assisted these students, to make their Birmingham experience better and help them through the rigors of graduate study. Lecturing to these students, I learned how to pace myself, and also how better to explain, often in different ways, aspects of the topics I was teaching. And working with the English unit staff (who would analyse our recorded lectures) I came to realise (as did my colleagues) just how often we use colloquialisms in everyday speech, and which are not easily translated for someone who is not a native English speaker.

Anyway, that experience of a decade’s worth of teaching overseas students stood me in good stead when I moved to the Philippines in 1991 and often had to give talks to diverse groups of visitors.

But returning to the opening premise of this post, about teaching qualifications for university staff, I think I would have welcomed much more formal feedback. Nowadays, there are mechanisms in place in universities to provide feedback. After all, the students are the clients who are paying handsomely for their education, and are not shy about denouncing poor teaching (and value for money) when warranted.

Three score and ten . . . plus five

It was my birthday yesterday.

Let me take this opportunity of thanking friends and former colleagues – from all over the world – who sent me birthday greetings. Very much appreciated.

One friend greeted me on achieving three quarters of a century. Now that sounds really old. Another wished me 25 years more. I replied that 10-15 would do me nicely.

In 1948, average life expectancy for males in England and Wales was only 65.9 years. Now it’s 79, due undoubtedly to increased living standards over the intervening decades leading to healthier diets, and better health propped up by the National Health Service that had been founded just a few months before my birth.

I wonder what hopes my Mum had for me on that day.

I was living in Congleton, Cheshire with my parents, Fred and Lilian Jackson, my brothers Martin (b. 1939) and Edgar (b. 1946), and sister Margaret (b. 1941). I started school around 1953.

Come 18 November 1958 – my 10th birthday – we had been living in Leek, Staffordshire for 2½ years already. I attended the local Catholic primary school, St Mary’s, just a few minutes walk from home, and hoped eventually to win a place at the Catholic grammar school in Stoke-on-Trent a couple of years later. Which I did.

Christmas 1958 in Leek (with my elder brother Edgar).

Moving on to 18 November 1968, I had just started the second year of my BSc degree course in environmental botany and geography at the University of Southampton. I had enjoyed my first year there, living in South Stoneham House, one of the halls of residence southeast of the university campus. I’d been elected Vice President of the Junior Common Room at the end of the first year, and that guaranteed me a second year at Stoneham. I guess I celebrated my 20th birthday in the pub with a few friends.

Over the previous summer vacation I’d attended an excellent botany field course on the west coast of island. And afterwards had spent several weeks with my girlfriend at her home just south of York or at my parents’ home in Leek. We also enjoyed a walking tour together of the North York Moors, staying at youth hostels (YHA) each night.

But our relationship was not to last. Just before the beginning of term in October, I received a Dear John letter from her. But not one to be downhearted for long, I picked myself up but forswore dating for a while.

And I threw myself into a new interest: morris dancing. Together with one of the botany department lecturers, Dr Joe Smartt, we founded the university morris side, the Red Stags (still active today, but in a different format and no longer associated with the university).

The Red Stags Morris Men after performing at the University of Southampton Open Day in March 1970. That’s me, kneeling on the right.

Along with my continuing enjoyment of English and Scottish folk dancing, this foray into morris dancing became one of my principal hobbies for the rest of my time at Southampton, and afterwards for several years.

I graduated from Southampton in June 1970, and by September I was studying once again at the University of Birmingham.

By my 30th birthday in November 1978, I already had MSc and PhD degrees from Birmingham under my belt, and had been working for the International Potato Center (CIP), an international agricultural research institute based in Lima, Peru for five years.

Steph (who I met in Birmingham) and I had been married for just over five years, and our first daughter Hannah was born in April. We were living in Costa Rica, but my work with CIP took me throughout the region, as well as to Mexico and the islands of the Caribbean.

If my memory serves me right, I ‘celebrated’ this birthday, a Saturday, on the Caribbean island of Montserrat. I was stuck in my hotel room in Plymouth (the island’s capital until it was destroyed in the Soufrière Hills volcanic eruption of the 1990s) while it rained cats and dogs outside.

In 1988, I had been teaching at the University of Birmingham for over seven years, in the Department of Plant Biology. It was a Friday. My 40th birthday. By then, my colleagues and I had developed a ‘tradition’ of celebrating in the Staff House bar at lunchtime (disgraceful!) with a bottle or two of Beaujolais Nouveau, the release of which always occurs around my birthday. Enjoying a bottle of the ‘new release’ was quite the rage in the UK back in the 1980s, perhaps less so today.

Hannah had turned 10 that year, and Philippa (born in Bromsgrove in 1982) turned six.

I left the university in 1991, to head the Genetic Resources Center (GRC) at the International Rice Research Institute (IRRI) at Los Baños, south of Manila, in the Philippines. In 1998, my GRC staff helped me celebrate my milestone 50th birthday. There must have been lots of snacks such as pancit and spring rolls and the like, ice cream (always vanilla!) and lots of cake. Probably donuts.

Then, in the evening, Steph and Philippa served champagne, and our helper Lilia had made a cake. Hannah was already away at university in Minnesota (where she still lives).

Steph and I celebrated our 25th (Silver) wedding anniversary just a month earlier.

A decade on, and I had changed jobs at IRRI, having moved from GRC to become the institute’s Director for Program Planning and Communications in May 2001.

I had an office suite in the main administration building, and my staff and others from nearby offices in HR and finance joined me to celebrate my 60th birthday.

With IRRI DG Bob Zeigler

Then, in the evening, Steph and I enjoyed the company of very close friends Corinta Guerta from my office, plant physiologist (and my closest friend at IRRI) John Sheehy, and Director for Development Duncan Macintosh (from Australia) and Cel (his Filipina girlfriend and now his wife) for an intimate dinner that almost ended in disaster before it had begun.

Nevertheless,we had a great time, but I think I must have drunk too much because I chose the wrong settings on my camera and the resulting images were not the best quality.

L-R: Corinta, me, Cel, John, and Steph

I retired from IRRI in 2010, and Steph and I returned to our home in Bromsgrove that we had first moved into way back in 1981, but which we’d kept furnished by unoccupied during the 19 years we stayed in the Philippines.

I celebrated my 70th birthday in 2018, and we did something I’d wanted to do for several years: a weekend away in Liverpool, visiting the childhood homes of Paul McCartney and John Lennon (both managed by the National Trust), as well as The Beatles Story beside the Royal Albert Dock.

We had a great weekend, taking the train from Bromsgrove (via Birmingham New Street) to Liverpool Lime Street. That was an added bonus. I love train journeys!

So here we are in 2023. It has become a tradition over the years for Steph to prepare my favorite meal on my birthday: homemade steak and kidney pie. I always look forward to that one special meal. And, as always, it was delicious, served with a bottle of good Portuguese red: Montaria Gold 2020 from the Lisbon region, a blend of Syrah, Alicante Bouschet, Trincadeira, and Aragonez grape varieties, made by Luis Vieira.

Had the weather been better we would have taken an excursion yesterday. But since the forecast had promised rain (which was the case) we headed north on Friday to the Alnwick Garden and the beach at Amble afterwards.

More plant blindness?

Tomorrow, 22 October, BBC1 will air Sir David Attenborough‘s next blockbuster 8-part series, Planet Earth III¹, just a year after his last series Frozen Planet II was broadcast.

Planet Earth III? From what I have seen in the trailer for the series, perhaps this should—once again—be titled [Animal] Planet Earth III.

There’s no doubt that the filming is spectacular, the ‘stories’ riveting. As one of the cinematographers has written, [the series] is set to be the most ambitious natural history landmark series ever undertaken by the BBC. It will take audiences to stunning new landscapes, showcase jaw-dropping newly-discovered behaviors, and follow the intense struggles of some of our planet’s most amazing animals (my underlining emphasis).

It’s not very likely that the series will feature plants much, if at all. Are plants being short-changed yet again? Of course there are many programs on television about gardening. But these don’t count, in my opinion, towards any greater understanding of and knowledge about plants and their uses.

That’s not to say that the BBC (or Sir David) have completely ignored plants. In January 2022, his five episode The Green Planet series was broadcast. It was, for me however, a bit like the curate’s egg²: good in parts.

And you have to go way back to 2003 for his The Private Life of Plants series, described as a study of the growth, movement, reproduction and survival of plants.

Before that, I can only think of Geoffrey Smith‘s World of Flowers double series, broadcast on BBC2 in 1983 and 1984, and apparently attracting an audience of over five million.

Who said there was no appetite for programs about plants? These programs weren’t your run-of-the-mill gardening programs. No, in each program Smith highlighted the origin and development of different groups of plant species commonly grown in British gardens.

Furthermore, conservation for many relates to animals. This is something my former Birmingham colleague Brian Ford-Lloyd and I wrote back in 1986.

So what has brought about this latest concern of mine? Well, I first came across the announcement for Planet Earth III‘s imminent broadcast on the same day recently that I subscribed to a new plant-based blog: Plant Cuttings. And there, on the home page, was the blog’s goal for all to see: to reduce plant blindness.

The blog is the creation of Mr P Cuttings (aka Dr Nigel Chaffey, a former senior lecturer in botany at Bath Spa University, and a self proclaimed freelance plant science communicator), and is dedicated to all those who find fascination in plants (and how they are used by people). You can find more about the rationale for and antecedents of Plant Cuttings here. It’s a continuation of the series of articles he published in Annals of Botany, the last one, Check beneath your boots . . ., being published in 2019 (also about ‘plant blindness’).

Unfortunately, plants are often seen as boring, especially by high school students who we need to attract to the plant sciences if the discipline (in all its aspects) is to thrive. Thus this initiative by PlantingScience, a Student-Teacher-Scientist partnership in the USA that was founded in 2005 by the Botanical Society of America.

Let me wish Nigel all the best as he develops this new Plant Cuttings blog. I’m very much in accord with his goals. After all, much of my career in the plant sciences has focused on the origin of the plants that feed us, how they can preserved for posterity in genebanks, and used to increase crop productivity.

So what sparked my interests in plants and human societies?

While a high school student, I first thought I’d become a zoologist. But I saw the light and my interests turned towards plants, and I took a botany degree (combined with geography) in the late 1960s at the University of Southampton.

One of the books that I read was first published in 1952 (I have the 1969 reprint) by American botanist Edgar Anderson. He wrote it for readers with little technical understanding of plants. After 70 years it has stood the test of time, and I thoroughly recommend anyone who has the slightest interest of the relationships between humans and plants to delve into Plants, Man & Life.

Thus I’ve been fascinated for decades about the beginnings of agriculture and how humans domesticated wild plants, and where, and to what uses they have put the myriad of varieties that were developed. My own expertise in conservation of genetic resources has permitted me to explore the Andes of Peru to find many different varieties of potato, the foundation on which Andean civilizations such as the Incas became successful.

Collecting potatoes from a farmer in northern Peru, May 1974.

A graduate student of mine worked out the probable origin of the grasspea, a famine crop in some parts of the world. And I’ve managed the largest genebank for rice in the world (rice feeding half the world’s population every day), and with my colleagues expanded our knowledge of the relationships of cultivated rices to their wild ancestors. I directed a five year program in the mid-1990s to collect cultivated rices from many countries in Asia and Africa, especially from the Lao PDR.

These are just three examples from all the plants which societies use and depend on. So many more, and so many fascinating stories of how civilization and agriculture developed.

Just recently, on holiday in North Wales, my wife and I came across the site of about 20 hut circles on the northwest tip of Anglesey, dating back to the Iron Age, some 2500 years ago.

Holyhead Mountain Hut Circles

What is particularly fascinating for me is that there is good evidence that crops like wheat, barley, and oats among others were being cultivated there 3000 years earlier. That’s about 4500 years after these crops were first domesticated in the Near East in Turkey and along the river valleys of the Tigris and Euphrates. In the intervening years, these crops were carried across Europe by migrating peoples as they headed west until they became staples on the far west of mainland Britain. The domestication and expansion of these crops is also the story of those societies.

Plants are definitely not boring. Botany opens up a host of career opportunities. Today we need to harness the whole range of plant sciences, from molecule to field, to understand and use all the genetic diversity that is safely conserved in genebanks around the world, and backed up in many cases in the Svalbard Global Seed Vault. We now have so many more tools, particularly molecular ones, at our fingertips to study plants.

Be sure to follow Plant Cuttings to find out more about the joy of plants and their value to humankind. I trust many more generations will be proud to say they became botanists (or, at the very least, took up one of the allied plant sciences).

¹I watched the first episode of Planet Earth III on BBC IPlayer catch up. Verdict: stunning photography but boring content, seemingly a rehash of so many nature programs. All animals. However, at 97, Sir David Attenborough is a remarkable presenter.

² A curate’s egg is something described as partly bad and partly good.

It doesn’t add up

Several weeks ago (or was it months?) UK Prime Minister Rishi Sunak (right) announced that his government would soon propose plans to reform secondary education for all pupils to study mathematics and English up to the age of 18, like many other countries.

After GCSEs (known as ‘O Levels’ back in the day when I was at school in the 1960s), taken at 15/16, many pupils receive no further tuition in maths (or English for that matter), and specialise in their final two years of high school, taking just three subjects, known as ‘A Levels’ (Advanced Level) as university entrance exams.

During his speech to the Tory Party conference on 4 October Sunak pledged to introduce this ‘revolutionary’ change. That’s assuming, of course, that the Tories remain in power after the next General Election. Which seems highly unlikely if the latest polls are to be believed. (Should Labour win the next election, I have no idea what its policy on continuing maths and English education will be, although as far back as 2014 they made it one of their policy pledges¹).

By teatime on the 4th, the Prime Minister’s Office had posted a press release on the government’s website.

Justifying this proposal, Sunak indicated that this new qualification for 16-19 year olds will put technical and academic education on an equal footing and ensure that all young people leave school knowing the basics in maths and English.

The new Advanced British Standard will bring together the best of A Levels and T Levels into a single new qualification. Students will take a larger number of subjects at both ‘major’ and ‘minor’ level, with most studying a minimum of five subjects at different levels – for example, three majors alongside two minors. Importantly, students will have the freedom to take a mix of technical and academic subjects, giving them more flexibility over their future career options.

However, it would take at least a decade to introduce such a change apparently. Very quickly, unions and teachers dismissed this proposed reform. Not, I hope, because they were opposed to reform in principle, but because schools do not have the staff or resources to teach English and maths to age 18. Yes, that is a real issue, and it will take political courage from the next government to tackle this issue head on, and support education at the level required. And to increase standards and achievements for GCSE students.

Notwithstanding there little or nothing about this Tory government I can support – and they certainly won’t have my vote in 2024 or whenever the election is called – I am actually in favor of this proposed educational reform. Let me explain.

When I was in high school (1960-1967), maths was one of my least favorite subjects. I dreaded maths lessons. But I did manage a pass in ‘O’ Level maths in 1964, but never took a maths course per se ever since. Much to my regret. And there are thousands of schoolchildren in exactly the same boat as me. Cowed by maths, and thus uninterested in the beauty of the discipline.

I often wish I had been able, had the ability, and perhaps more importantly had the support of good maths teachers to instill a continuing interest. I had really poor teachers at my high school, only interested in those who could and tolerating (just) those who struggled.

Having said all this, I have spent much of my career in agricultural science working with numbers, and thoroughly enjoying it. Indeed, in 2017 I wrote this blog post, There’s beauty in numbers, about my enjoyment of playing with data, looking for patterns and trends, and coming to conclusions about the behavior of the plants and crops I was studying. But although I became reasonably proficient (under guidance and advice from those better experienced than me) in the use of statistics, I do wish I had a better theoretical background underlying some of the statistical concepts I applied.

But beyond the basics of algebra, geometry, or trigonometry that high school pupils receive leading up to GCSEs, most do not need higher levels of mathematical education, like calculus for example. What they do need, in my opinion, are good numeracy skills, and how maths operates in the real world.

And as far as English is concerned, my emphasis for many students would be having the ability to write coherent prose and learning how to communicate effectively, both in written form and verbally. No need for deep analysis of set texts by Shakespeare or others.

So how would they achieve this? Sunak’s proposed Advanced British Standard qualification is his solution.

Often referred to (in previous government statements) as an English or British Baccalaureate, the Advanced British Standard seems remarkably similar to an existing and widely accepted qualification: the International Baccalaureate Diploma, offered in over 3600 state and private schools worldwide (but in just 22 state schools in the UK, although offered in 71 private ones).

If a widely-accepted qualification is up and running, and has been for decades, since 1968 in fact, why bother to reinvent the wheel with the Advanced British Standard? Is this another case of British exceptionalism?

This is what one headmistress, Victoria Hearn (right), Principal of state-assisted Impington Village College and Impington International College near Cambridge had to say about the proposal in a letter to The Guardian on 27 September last:

While Rishi Sunak’s plans to reform post-16 education are welcome news, I can’t help but feel that valuable resources could be saved by utilising a tried and tested education framework that students are already benefiting from. The international baccalaureate (IB) diploma enables students to study six subjects including mathematics, English and a foreign language until the age of 18, providing a broader and more rewarding syllabus compared with that of the UK’s national curriculum.

The development of a “British baccalaureate” will be costly, and funding this new vision will be a concern to many, particularly for state-funded schools that are already overstretched. In the UK, the IB is often seen as only accessible to independent schools, but with some creative budgeting and timetable management, a comprehensive IB programme can be delivered by state schools. We have been offering the IB at the state-maintained Impington Village college for more than 30 years as we believe it places our students in the best position to succeed in the global workplace.

Adapting the current curriculum framework is going to be lengthy and costly. The IB represents a proven alternative that can give students the broad range of skills required to thrive in the future.

Also, these are the IB values:

valuing inquiry and reflection, encouraging students to be open minded in their learning;
being principled and encouraging a caring attitude;
promoting high quality communication and discussions within the school community; and
encouraging international-mindedness and building respectful relationships.

I couldn’t agree more. And here are some reasons why.

First, from my own experience, I believe keeping your options broad is a positive perspective. In fact,

I studied both humanities and sciences at ‘A Level’: English Literature, Geography, and Biology (and General Studies).
I read for a combined BSc degree at the University of Southampton (1967-1970) in Environmental Botany and Geography.
For my MSc degree at the University of Birmingham in the conservation and use of plant genetic resources (1970-1971) many different topics were included.
It wasn’t until I began my PhD on potatoes (awarded 1975) that I settled into a narrow discipline.

Second, I don’t agree with either the retired teacher who thinks that additional ‘useless’ subjects in a baccalaureate would not be appropriate for many pupils, or the Emeritus Professor of Mathematical Education, who felt that students applying for maths at university would not have appropriate preparation. Both expressed their views in letters to The Guardian. The professor seemingly doesn’t appreciate that IB subjects are taught at both a higher and lower level. And, in any case, from my experience as a university lecturer (1981-1991, in plant biology in the School of Biological Sciences at the University of Birmingham) many first year university courses are designed to bring everyone up to the same level.

Furthermore, and again from my university days as a tutor, many students would certainly benefit from having a received a broader pre-university education, that would have given them a broader perspective on life, with access to the humanities as well as sciences, and would have enhanced, I believe, their ability to think and discuss more critically, and present their ideas verbally as well as written.

And lastly, both my daughters took the IB Diploma, and emerged with highly creditable grades at age 17, with subsequent access to good universities in the USA and UK, and endowing them with the academic capabilities and discipline to graduate with excellent degrees, and subsequently taking a PhD each in psychology.

But, I should add, their IB Diplomas were not earned at a British state school. In July 1991, I took a senior position with the International Rice Research Institute (IRRI) in the Philippines. My wife Steph and daughters followed me out to the Philippines by the end of the year, when Hannah and Philippa were 13 and nine (and had just moved up to high school and middle school respectively just three months previously in our home town, Bromsgrove, in Worcestershire).

Steph and I discussed the various education options. We were not keen in sending them to boarding school in the UK. There was a British School in Manila, but that did not, in the 1990s, offer an ‘A Level’ curriculum. So, after GCSEs, we would have had to send them back to the UK. Again not something we considered.

So both were enrolled in the fee-paying International School Manila (ISM), with the expectation from the outset that the IB Diploma would be their pre-university goal. Fees were subsidised by my employer as many IRRI children were also enrolled there, and traveled the 70 km daily each way north from Los Baños, where IRRI’s research center is located, into the city.

Yes, the courses were tough. Since besides the six academic subjects (three at higher, three at lower), IB students took a Theory of Knowledge course. Both our daughters studied English, history, and biology at higher level, and maths studies, French, and psychology at lower level.

Each had to complete a 4000 word essay based on independent research. Hannah’s history project was an analysis of the impact of the railways on the canals in mid-19th century England. Philippa made an analysis of A Shropshire Lad, an epic poem by Bromsgrove classical scholar poet, AE Housman (whose statue, right, proudly stands in the High St there) and interpreting his repressed sexuality through the poem’s themes.

For her community project, Hannah helped each weekend at a Montessori school in Los Baños, while Philippa joined a group for two weeks helping to construct a road in the mountains north of Manila.

There was one last challenge: the daily journey into Manila. Classes began at 07:15, and by the time my younger daughter graduated in 1999, the IRRI bus for ISM was departing from Los Baños at 04:30, and not returning until 16:30 or later. Then there were homework assignments to complete until late evening. All the family was relieved come graduation!

I’ve asked them about the IB experience. Both were unequivocal. The Diploma gave them enhanced skills for critical thinking, time organization, as well as covering the various subjects in depth. They both said the Diploma was a worthwhile qualification. It certainly hasn’t held them back.

So as the discussion continues over post-16 education and whether to replace ‘A Levels’ with a broader curriculum qualification, it’s certainly worthwhile looking at the IB mix, and what level of maths and English education and skills most students really need to prepare them for the workplace, and life in general.

Traveling for 55 years

I have been very fortunate. There’s no denying. Since I made my first trip outside the UK, to the west coast of Ireland for a botany field course in July 1968, followed a year later, in September 1969 to participate in a folk festival in Czechoslovakia, I’ve had so many opportunities to travel around the globe—to more than 60 countries (sometimes on vacation, but mostly on business associated with my work in international agricultural research).

Morris dancing at the folk festival in Strakonice, Czechoslovakia in 1969. That’s me on the extreme right.

I’ve lived and worked in three countries (besides the UK of course): Peru (1973-76); Costa Rica (1976-1980); and the Philippines (1991-2010). I’ve visited several countries multiple times, and others just the once. Whenever I was traveling on business, I would also try to fit in some tourism over a weekend if possible. I have so many memories over those 55 years. Here are some that spring to mind.

The Americas
I guess I should begin this section with Peru. In 1971 I was thrilled to be offered a job in Peru, at the newly-founded International Potato Center (CIP), although I didn’t actually travel there until January 1973.

13 October 1973

So many memories. Steph and I were married in Lima in October 1973.

My work took me all over the Andes collecting native varieties of potatoes (and some of the hundreds of wild species of potato that are indigenous to Peru). And Steph and I made several road trips to the north, central, and southern Andes. I visited Machu Picchu twice, and we saw some remarkable sights and sites.

It’s almost impossible to choose any one aspect that stands out. The diversity of landscapes, with desert on the coast, the high Andes, and the jungle on the eastern side. The long history of agriculture in difficult environments, and the archaeology of civilizations that go way back before the invasion by the Spanish in the 16th century.

Then we moved to Costa Rica in April 1976, living in Turrialba, about 70 km east of the capita, San José. Once again I was working on potatoes and with farmers.

We enjoyed our five years in that beautiful country, and our elder daughter Hannah was born there in April 1978.

A land of volcanoes (some very active), Costa Rica is a verdant country, and there are national parks everywhere. The bird and plant life is extraordinary, so I guess this is what stands out for me in particular.

On a visit to the Poas volcano

My work took me to all the countries of Central America, as well as to Mexico where, until 1977, CIP’s regional headquarters was based just outside Mexico City at Toluca. And also out into the Caribbean islands, to Haiti and the Dominican Republic, to Jamaica, St Kitts, Antigua, Montserrat, Barbados, and Trinidad.

In Mexico, most of my visits were to Toluca. But on one visit there, I joined the participants of a potato training course to study potato production in Mexico State, Michoacán, Puebla, Jalisco, and Guanajuato. Later, in the 1980s I also visited Nuevo Leon in the north, and Morelos south of Mexico City.

But if I had to choose one highlight, it would be the pyramids at Teotihuacán, northeast of Mexico City that Steph and visited in 1975 when we visited some friends at CIMMYT (a sister center to CIP) on our way back to the UK.

Guatemala is a fascinating and beautiful country, and I was a regular visitor. A land of lakes and volcanoes, it has a high indigenous population, who wear the most colorful fabrics.

In 1977, Steph and I flew into the Mayan city of Tikal, deep in the jungle, for an overnight stay.

On another trip I spent a few days in Belize, first in Belize City on the coast, then in Belmopan, the smallest capital city in the Americas.

The overriding memory I have of Honduras was the white-knuckle landings in Tegucigalpa. How they managed to land jets there is beyond me. What pilot skill!

I visited El Salvador and Nicaragua just once each, and then only overnight. They had virtually no potato sector.

Flying in and out of Panama City was quite a regular occurrence. It was a transit for Costa Rica from South America. The main potato area was in the west of the country near the frontier with Costa Rica (map), north of the city of David at Volcán and Boquete. A region of deep volcanic soils, it was very good potato-growing country, and one I traveled to by road from my base in Turrialba on a couple of occasions.

Potato fields in Boquete, northern Panama

It was only after I moved to the Philippines in 1991 that my work took me back to Costa Rica for the first time in about 15 years, and one other country, Venezuela, which I’d not visited before although landing at Caracas airport on several occasions. This airport is located on the Caribbean coast north of the city, and is connected by a 27 km motorway that crosses the mountains, a spectacular drive over what I assume is a northern extension of the Andes.

In the 1990s I spent a week in Caracas attending a potato network meeting, but seeing very little of the city, just the metro from hotel to meeting venue and back!

Another international agricultural research center in Cali, Colombia is CIAT (map), supported in the same way as CIP and CIMMYT (and the rice institute, IRRI, in the Philippines, that I joined in 1991). Located in the Cauca Valley, CIAT is surrounded by huge plantations of sugar cane, but the rice-growing area is nearby as well. The last time I was there (and in Peru and Mexico) was in July 2016 conducting a review of the CIAT genebank.

I was in Chile just the once, for a week in Santiago in July 1979. I’d flown down from Costa Rica to join two colleagues from Lima to carry out a short review of the Chilean potato program. Two things come to mind: wine and ABBA. Wine, because we were taken to dinner at Enoteca, a fine restaurant overlooking the city on Camino Real, where all the wines produced in Chile were on display, and we were invited to sample many of them. On one evening, while out enjoying some souvenir shopping, I heard (for the first time) the refrains of Chiquitita by ABBA emitting from one of the shops. My visit to Santiago will always be associated with ABBA.

What can I say about Brazil? It’s huge. My first visit there was in 1979 when I attended a potato conference at Poços de Caldas in Minas Gerais (map), followed by a couple of nights in Rio de Janeiro. On another occasion I attended a conference in Foz do Iguaçu (in Paraná state) close to the border with Argentina and Paraguay, and site of the impressive Iguazu Falls.

I’ve been to Brasilia twice, and once upon a time, that nearly became home for Steph and me when CIP’s Director General deliberated whether to post me to Brazil or the Philippines. In the event we returned to the UK in 1981 when I joined the faculty of the University of Birmingham.

I guess the most impressive thing I’ve experienced in Brazil is the statue of Christ at Corcovado, high above Rio de Janeiro, with the most spectacular views over the city. My dad was there in the 1930s.

I’ve been to Canada twice, the first time in 1979 (with Steph and 15 month-old Hannah) when I attended a potato conference in Vancouver, then we drove across the Rockies to meet up with my late elder brother Ed and his wife Linda in Edmonton, AB.

In the early 2000s, I made a short visit to Ottawa to meet with representatives of Canadian overseas development assistance agencies, and managed to spend a day getting to know the city, before heading back to the USA.

Over the decades I’ve traveled to the USA many times, and have now visited all states and DC except Hawaii, Alaska (although one flight touched down in Anchorage), Idaho, Nevada (I changed flights in Las Vegas), Oklahoma, Kansas, North Dakota, Louisiana, Mississippi, and Alabama. It’s such a vast country, but since 2011, Steph and I have managed several mega road trips and seen so many wonderful sights. It’s hard to pick any one. I have written about these trips and you can find a link here; just scroll down to the USA section).

But what highlights do I choose? The Oregon coast, Crater Lake, or the redwoods of northern California? Or would it be canyon country in Arizona? How about Yellowstone National Park, the Appalachians, the Mississippi River, Mt Washington in New Hampshire, or the coast of Maine? What about the Civil War sites like Gettysburg?

However, I’ve often said since we made the visit there in 2011, that if I ever got the opportunity to return, it would be to Canyon de Chelly in northeast Arizona. It’s a special place.

Canyon de Chelly, AZ

Spider Rock in the Canyon de Chelly

There’s not a lot of potatoes grown throughout the Caribbean, with only the Dominican Republic having any significant potato program, in the central highlands close to the border with Haiti. The Dominican Republic became one of the founder members of a regional potato program, PRECODEPA, set up in 1978, so I guess I must have traveled there five or six times.

I was just the once in Haiti, in the late 1970s attending a conference for about a week. We stayed in a nice hotel overlooking Port-au-Prince, and ventured out into the city just the once. Even then the city was not a safe place to wander round, and following the disastrous 2010 earthquake followed by the cholera outbreak, the country has become even more ungovernable, and not somewhere I would want to visit again. It’s one of the poorest countries in the Western Hemisphere.

I also paid short visits to Jamaica, St Kitts, Montserrat (which had a small but thriving potato sector before the Soufrière Hills volcano erupted in 1995, covering half the island with ash), Barbados, and Trinidad. Before long-haul jets could make the flight direct from Europe to South America, Antigua was a refuelling stop, which I made a couple of times. And after being being bumped off a flight to Montserrat, I spent the night in Antigua at a luxury resort (the only hotel bed I could find on the island!) and enjoying a delicious lobster dinner for the same price as a steak.

Asia
Let’s turn to Asia now. I spent almost 19 years in the Philippines, joining the International Rice Research Institute (IRRI) in 1991, first as head of the Genetic Resources Center (GRC, and managing the world’s largest genebank for rice) until 2001, when I became the institute’s Director for Program Planning and Communications (DPPC). In both roles my work took me all over the world. But let’s focus on the countries in the region to begin with.

My first trip to Asia, to Indonesia in fact, was in the early 1980s, when I attended a genetic resources meeting in Jakarta, but spending a weekend at the Bogor Botanical Garden beforehand. The oil palm tree on the right below is one of the original trees introduced into Asia and became the foundation of the oil palm industry.

Over the 19 years I spent living in the Philippines, I returned to Indonesia several times, the most memorable being in September 2005 when the IRRI Board of Trustees held one of it bi-yearly meetings there. Steph was able to join me on that trip, and along with excursions into the Bali countryside, we also enjoyed a long weekend break at our hotel before returning to the Philippines.

Bali landscape, Indonesia

In the Philippines, we lived in Los Baños, some 60 km south of Manila, where IRRI had its research center.

On the IRRI experiment station, with Mt Makiling (a dormant volcano) in the background.

Although we didn’t travel much around the Philippines (and apart from one short trip to Cebu, we didn’t wander beyond the island of Luzon), we went to the beach most months, and in March 2009, Steph joined me and my DPPC staff when we took an office outing over five days to the rice terraces in the mountains north of Manila. Very impressive.

Looking south towards Banaue town center.

In 1993 I learnt to scuba dive, one of the best things I’ve ever done, opening up a totally new world for me. The Philippines has some of the best diving in the world, especially at Anilao south of Manila.

Diving at Anilao, Philippines

But one of the best things about the Philippines? The Filipinos! Always smiling. Such friendly people. And I had great Filipino colleagues working with and for me in both the roles I took on at IRRI.

In 1995, I launched a major rice biodiversity project (funded by the Swiss government), and one of my staff, Dr Seepana Appa Rao was recruited to help the national rice program in Laos to collect native varieties of rice. Over five years, I visited Laos at least twice a year, taking part several times in a baci ceremony to welcome me to the country, and other visitors as well. Steph joined me on one trip, and here we are during one such ceremony at the house of my colleague, the late Dr John Schiller.

On that particular trip, we took a weekend off, flying to Luang Prabang and enjoying a river trip on the Mekong.

Mekong River, nr. Luang Prabang, Laos

IRRI had a country program in Cambodia, and I visited a couple of times to discuss rice germplasm conservation, and stayed in Phnom Penh. But after Christmas 2000, Steph and I were joined by our younger daughter Philippa (who had just begun her undergraduate studies at the University of Durham in the UK) for a mini-break in Cambodia (and Singapore).

We flew from Phnom Penh to Siem Reap, and spent three nights there visiting the amazing Angkor Wat temple complex, and a boat trip on the Tonle Sap, before flying back to the capital for one night, and back to Singapore.

We celebrated the New Year in Singapore, taking in the beautiful botanic gardens. Work has taken me to Singapore on several occasions, and Changi airport has to be one of the world’s aviation destinations. How it must have changed since I was last there.

Work took me to Seoul in South Korea on several occasions, and Japan. Steph joined me on one trip to Japan in September 2009 when the IRRI Board of Trustees met in Tsukuba north of Tokyo. We stayed on for a long weekend sightseeing in Tokyo, although she got to see more than I did earlier in the week, when a series of excursions for IRRI and Trustee wives were organised from Tsukuba.

Narita airport was also a hub for Northwest Airlines (now Delta) for flights from Manila to the USA, so I would fly through there at least a couple of times a year, also Osaka.

I’ve been to Beijing in China a couple of times, taking in the Great Wall during my first visit in 1995.

With my colleague, Bao-Rong Lu (middle) on the Great Wall, north of Beijing

On that trip we also took in Hangzhou and Guangzhou. I was in Beijing again around 2005 for a meeting, and in 2004, Steph and I flew to Hong Kong over Christmas and New Year. We also crossed to Macau on that trip.

Ruins of St Paul’s, Macau

Again, Hong Kong was one of those hub airports that I passed through many times, first at the old Kai Tak airport alongside Kowloon harbor (an interesting approach), and later at the new airport reclaimed from the sea.

I’ve only been to India a handful of times, always to meetings, and only then to Delhi and Hyderabad, so I can’t say that I’ve ever seen much of the country. There’s no doubt it’s a fascinating country, but I’m not sure it’s really on my bucket list – except if I could travel on one of those luxury trains, perhaps.

The same goes for Bangladesh, with just a couple of visits to Dhaka so I can’t say that I’ve ever known the country.

I was in Sri Lanka just the once, spending most of my time in Kandy. The hotel where I stayed was outside the city, on a hill, with breath-taking views over the surrounding hills. And I remember waking up early one still morning, and listening to the bird calls echoing all around. Magic!

I been to the north and south of Vietnam. On my first trip, I traveled to Can Tho in the Mekong Delta, and on the return journey to the airport in Ho Chi Minh City, I had to cross the river in a small boat (the bridge was down) and flag down a tuk-tuk for the last 20 km or so. I caught my flight!

Then I was in Hanoi several times in connection with the rice biodiversity project, but in 2010 I was the chair of the science committee for the 3rd International Rice Congress held in that city.

Myanmar has been closed off to visitors for many years, but I was able to visit just the once in the late 1990s, to the rice genebank at Yezin, about 250 miles north of the old capital Yangon. The train ride was interminable, and the sleeper on the return journey left a lot to be desired in terms of comfort and cleanliness. Nevertheless it was an interesting visit, but compared to the cuisine of other countries in the region (especially Thailand and Indonesia) the food was not inspiring: served quite cold and swilling in oil.

I’ve been in Bangkok many times, as it where I would change flights for Vientiane in Laos, having to spend one night to catch the early morning flight on Thai or Lao Airlines. But I never got to know the country, just a couple of visits to Chiang Mai in the north (again for meetings but no tourism). The same goes for Malaysia, with meetings in Kuala Lumpur and Penang.

In 2014 IRRI once again asked me to chair the science committee for the 4th International Rice Congress that was held in Bangkok, so I made several visits there (and on to the Philippines) before the congress was held in November.

Australia
I’ve been in Australia four times. As a family, Steph, our elder daughter Hannah, Philippa and I flew from the Philippines just after Christmas 1998 to Sydney, spending just under a week there, enjoying a trip up into the Blue Mountains, and watching the awesome fireworks display over Sydney Harbour on New Year’s Eve.

I made a work trip there around 2001, taking in Canberra, the rice-growing area in the Riverina, Adelaide, and Melbourne.

In December 2003, Steph and I drove from Sydney to Melbourne over the course of a week, taking the train back to Sydney, where we enjoyed a harbour dinner cruise.

We spent New Year’s Eve on the south coast near Melbourne.

Next stop: Antarctica

The last time I was there was November 2016, when my friend and former colleague, Professor Brian Ford-Lloyd flew from Birmingham to Melbourne for three days as part of a review of genebanks.

Enjoying a stiff one on the Emirates A380 flight from Melbourne to Dubai.

Africa
Africa now, where I have visited Morocco in the north, Ghana, Ivory Coast, and Nigeria in West Africa, Ethiopia and Kenya in East Africa, and Zambia, South Africa, Mozambique, and Madagascar in southern Africa. I wrote this general account in 2013.

There are several international agricultural research centers in Africa: ILRI (a livestock center) in Kenya and Ethiopia; World Agroforestry (ICRAF) in Kenya; IITA in Ibadan, Nigeria; and Africa Rice (WARDA) in Bouaké, Ivory Coast. I have attended meetings there on several occasions. In Ethiopia, the ILRI campus is located in Addis Ababa, and during my first visit there, in January 1993, I had the opportunity of traveling down into the Rift Valley. What I most remember about that trip, and the stay in Addis, was the incredible bird life. An ornithologist’s paradise. Likewise on the campus of IITA in Nigeria. IITA has a 1000 ha campus, and part of it has been left as pristine rainforest with its assemblage of species, some of them crop wild relatives.

Looking for wild yams on the IITA Forest Reserve.

I made my first visit to Nigeria and Ivory Coast after the genetic resources meeting in Addis Ababa in 1993. For security reasons, visitors to IITA who arrive in Lagos in the afternoon and evening spend the night there, before being escorted to Ibadan, around 2 hours by road to the northeast. I always enjoyed my visits to IITA. But Lagos airport was another thing. The situation there did improve, but throughout the 1990s, I always felt uneasy passing through, as officials (some in uniform, others in plain clothes) would often ask for a bribe.

I must have visited Ivory Coast a couple of times, the first time flying from Abidjan (the capital) to Bouaké on the national airline, a Boeing 727 that had once been the presidential aircraft! I made those visits before the disastrous civil wars of 2002-2004 and 2010-2011.

Africa Rice had to abandon its research center in Bouaké for many years, although the institute has now returned there. I planted a tree during my first visit. I wonder if it’s still there?

On another occasion, I was in Ghana for a week, attending a planning meeting, and didn’t see much of Accra outside my hotel.

I’ve been in Kenya probably half a dozen times, straddled the Equator, and enjoyed the wildlife in the Nairobi National Park.

With my dear friend from CIMMYT, the late Sir Bent Skovmand (from Denmark), wheat pathologist and then head of the CIMMYT wheat genebank.

In October 2005, I was in Marrakech, Morocco to attend the annual meeting of the CGIAR, the consortium of donors and international centers. I got sick, and I had to work on a project proposal so spent much of my time in my hotel room, with just one excursion to the souk for some souvenir shopping.

Looking for silver beads for Steph.

In southern Africa, I spent several days in Lusaka, Zambia visiting the SADC genebank there. I’ve passed through Johannesburg several times, and on my transit there (on my way to Lusaka) was caught up in a car bomb incident on the day of the election that first brought Nelson Mandela to power in April 1994. On another occasion I spent a week in Durban (meetings once again) with a side trip to Pietermaritzburg, almost 90 km inland from Durban,

IRRI had a country program in Mozambique, and I was there a couple of times. The rice program joined our biodiversity project, and the CGIAR held its annual meeting there in 2009.

I was in Madagascar just the once, staying in the capital Antananarivo on the east coast, and traveling along dreadful roads north to the rice experiment station. Madagascar also participated in the rice biodiversity project.

At a training course on rice genetic resources in Madagascar in 1998.

Middle East
I had the opportunity of visiting Izmir in Turkey in April 1972, one of my first overseas trips from Birmingham, to attend a genetic resources conference. There was an excursion to Ephesus.

On another visit (also to Izmir) in the late 1970s, I spent a day in Istanbul before taking an evening flight to the UK, enjoying the Topkapi Palace and various mosques.

The Blue Mosque

I was fortunate to travel to Syria several times, to Aleppo, before the civil war pulled the country apart. Another agricultural research center, ICARDA, had its headquarters there and genebank. I even went for a job interview once. It’s a beautiful country, and I guess many of the beautiful almond orchards have probably been destroyed in the fighting. I also spent some time in Damascus, visiting the famous souk there.

In 1982, I took a party of graduate students from the University of Birmingham to Israel for a two week course on genetic resources of the Mediterranean. I wrote about that visit here.

And then there’s Dubai in the United Arab Emirates. I’ve spent a few nights there in between flights but never had enough time to explore the city. When Emirates Airlines began a service from Manila (MNL) to Dubai (DXB), and on to Birmingham (BHX), we flew that route each year on home leave, and Emirates also became my airline of choice for trips into Europe. In the 1990s it had either been with Lufthansa into Frankfurt (FRA) or KLM into Amsterdam (AMS).

Europe
Steph and I have been married almost 50 years but we’ve never taken a vacation on mainland Europe. But my work has taken me there quite often, and to three countries, Germany, Switzerland and especially Italy, several times a year between 1991 and 2010.

On that first trip to Czechoslovakia in 1969, we traveled by road, through the Netherlands, southern German, and into Czechoslovakia.

I was next in Germany in the late 1980s, when I visited agricultural research institute near Hannover (also taking in the scenic town of Celle), before crossing into East Germany. I spent several interesting days at the genebank in Gatersleben (now part of The Leibniz Institute of Plant Genetics and Crop Plant Research), before flying on to Warsaw in Poland.

There I gave a series of seminars on crop evolution and genetic conservation (focusing on potatoes) to staff of the agricultural research institute (IHAR). My hosts took me to the family home of Frédéric Chopin west of Warsaw. As we walked around the gardens, we could hear several of Chopin’s piano pieces broadcast over speakers there. His Mazurka in D Major has remained a firm favorite ever since (here interpreted by acclaimed pianist Vladimir Horowitz), and is always a reminder of that visit whenever I hear it.

I also took in Cracow in the south of the country, a most elegant city.

While I was DPPC at IRRI, my work with the institute’s donors took me many times into Europe, particularly to Germany (Bonn and Frankfurt), to Switzerland (at Bern), and to Rome in Italy.

I had a good friend, plant pathologist Dr Marlene Diekmann, who lived near Bonn, and who worked for one of the German aid agencies. Whenever I was in Bonn, we’d try and spend some time walking the wine terraces of the Ahr Valley south of Bonn.

The last time I was in Bonn was 2016 during the genebank review I mentioned earlier.

I love trains, and have often traveled that way from one European capital to another. In fact I have traveled from my former home of Bromsgrove in Worcestershire to Rome, with stops in Belgium, Germany, and Switzerland on the way.

One of the best trips I made was to view the Matterhorn in Switzerland near Zermatt. I had a free weekend before I had to travel on to Rome, so I took the opportunity of a day excursion from Bern.

My trips to France have taken in Paris, where I spent a very wet weekend once walking around the city. But it was worth it. And to Montpellier on the Mediterranean coast several times, the last being in 2016.

Brussels (in Belgium) has a beautiful central square, but I’ve never had much time to explore there.

For many years, Amsterdam was a hub airport for home leave flights back to the UK. In the Netherlands, I’ve spent time in the university town of Wageningen (east of Amsterdam), in the capital, The Hague, and in Amsterdam itself. A boat tour of the canals is well worth it.

My donor trips took me to Lisbon in Portugal and Madrid in Spain, which I wrote about in this blog post from 2019. Then in 2012, Steph and I visited my late eldest brother Martin and wife Pauline at their beautiful home in Tomar, north of Lisbon. What a glorious 10 days.

I was in the Canary Islands (part of Spain) a couple of times, collecting various wild crop relatives. Steph, the girls, and me had a holiday there in 1989.

Looking over the Tenerife landscape.

However, the country I have visited most in Europe is Italy, and Rome in particular. I was once in the Po Valley southwest of Milan, looking at the rice research there. The Food and Agriculture Organization of the United Nations (FAO) has its headquarters in Rome, as does Bioversity International (formerly the International Plant Genetic Resources Institute, IPGRI). I guess over the 19 years I spent in the Philippines, I must have traveled to Rome at least once a year for one meeting or another, and up to five times in one year. It’s a magnificent place, although my elder daughter Hannah who has just spent a few days there commented on how dirty it was, and full of tourists. But I’ve always enjoyed my stays there, and have had ample opportunity to enjoy the history and archaeology, and the fantastic cuisine.

I’ve only been in Austria, Norway, and Denmark on one occasion each, and in the capitals Vienna, Oslo, and Copenhagen. In Vienna, I spent a week at the International Atomic Energy Agency (where they have a program in mutation breeding) consulting on germplasm databases. I visited donor agencies in Norway and Denmark, but had no time for any tourism in Oslo. It was a different situation in Copenhagen where I looked round the pretty city over a weekend.

I started this blog post in the Republic of Ireland, and Steph and I have returned there three times, two with Hannah and Philippa in the 1990s, and also in 2017 after we’d spent a little over a week touring Northern Ireland.

Northern Ireland was a revelation. Prosperous, and beautiful. We visited many National Trust properties over there, and I wrote about our 10 days there afterwards, with links in the post to many of the properties we visited.

Giant’s Causeway, Northern Ireland

In Great Britain (United Kingdom minus Northern Ireland), Steph and I have visited so many National Trust and English Heritage properties around the country. This link gives a complete list (and maps) of all those we have visited.

Since we returned to the UK in 2010, we have toured Scotland, spent time in the south and southeast of England, and in Cornwall.

Now that we are living in the northeast of England, we have spent time exploring Northumberland, including its incredible Roman heritage.

The Whin Sill along Hadrian’s Wall

As a small boy, I spent many holidays with my parents in different parts of Wales, and Steph and I will be returning there at the beginning of September to renew our acquaintance with North Wales after so many decades.

So, there we have it. Fifty-five years of travel. So many special experiences.

Time out in Minnesota: 2. Beside, above, and on the Mississippi

I’m totally unfamiliar with the convention that gives names to rivers.

The Mississippi is only the second longest river in the United States. At 2,340 miles it’s shorter than the Missouri, by just one mile apparently. Yet, when they come together (or the Missouri flows into the Mississippi) north of St Louis, the river takes on the name of the Mississippi. And again, near Cairo in southern Illinois, the Ohio joins the Mississippi, and loses its identity thereafter even though the Ohio is a much bigger river in terms of discharge (but shorter) at that point.

The Mississippi flows through 10 states: Minnesota, Wisconsin, Iowa, Illinois, Missouri, Kentucky, Tennessee, Arkansas, Mississippi, and Louisiana. It flows through Minnesota for 681 miles, the most miles of any state.

By the time the Mississippi reaches Minneapolis-St Paul (the Twin Cities) from its origin at Lake Itasca in the northern part of the state (which we visited in 2016), it’s already an impressive river, fast flowing, deep, and wide. Our elder daughter Hannah lives just a stone’s throw from the bluff overlooking the river, which you would easily see if it wasn’t for the dense stand of trees on both banks.

That line of trees across the road from Hannah’s is the top of the Mississippi Gorge bluff.

Nevertheless, there are various scenic viewpoints, riverside regional parks, and overlooks in the Twin Cities where you can admire the majesty of the river. Whenever we visit our daughter and her family, we always take the opportunity of spending some time beside the Mississippi. I somehow feel it drawing me to its banks.

During this year’s Minnesota vacation, we decided not to make any long distance road trips as we have done in previous years (and which you can read about in the USA section of my blog here). Except for one overnight stay at La Crosse on the Mississippi in Wisconsin, about 150 miles south of the Twin Cities. And for a very special reason, that I’ll come to in a moment.

The route south on US61 and US14 follows the river, and you’re never very far from it. In several places the Mississippi opens out into large lakes before continuing its flow south to the Gulf of Mexico. And it was while we were driving along that I realised just how close to the river the railroad line was built, and which we experienced in 2015 on Amtrak’s Empire Builder to Chicago and back.

So why the visit to La Crosse? A couple months back I was contacted by an old friend of 50 years, Roger Rowe, who lives in Peru with his wife Norma. Now 87, Roger was planning to visit central Illinois where his younger brother farms corn and soybeans, and would be celebrating his 80th birthday. Knowing of our visit to St Paul, Roger enquired whether we could meet up, halfway (more or less) between Princeton, IL and the Twin Cities. And that’s precisely what we did on 6/7 June.

Just after I joined the International Potato Center (CIP) in January 1973, a workshop was held to plan for a research program on the conservation of cultivated and wild potatoes from the Andes, and their taxonomy. At that time, Roger was the geneticist/curator of the USDA’s potato collection at Sturgeon Bay in Wisconsin, and one of the participants of the workshop.

Here we are in the field in Huancayo, in central Peru where CIP grew its large potato collection.

L-R: David Baumann (CIP), Dr Frank Haynes (North Carolina State University), Professor Jack Hawkes (University of Birmingham), Dr Roger Rowe (USDA-Sturgeon Bay), and Dr Donald Ugent (University of Southern Illinois-Carbondale).

Several months later, in May 1973, Roger joined CIP as the head of the breeding and genetics department and became my first boss there. He also became a co-supervisor (with Jack Hawkes) of my PhD dissertation. Steph joined CIP in July as an associate geneticist in the same department.

So, 50 years later, we were again reunited on the banks of the Mississippi in La Crosse.

We enjoyed several beers and dinner together, reminiscing over old times, as well as putting the world and the CGIAR to rights.

After I left CIP in 1981 to take up a faculty position at the University of Birmingham, I didn’t meet up with him again until 1993, although I’d met Norma in Mexico during a British Council-sponsored visit to that country in 1988.

In the late 1980s, Roger became the Deputy Director General for Research at the International Maize and Wheat Improvement Center (CIMMYT) after a spell working in Africa. We met for the first time after many years when attending the annual meeting of the CGIAR’s Inter-Center Working Group on Genetic Resources, held at the ILCA campus in Addis Ababa in January 1993. By then I was leading the genetic resources program at the International Rice Research Institute (IRRI) in the Philippines.

From CIMMYT, Roger joined another CGIAR center, ICLARM (later becoming WorldFish) as Deputy Director General for one of its programs based in Egypt. Steph and I would meet up with Roger for Sunday breakfast in Manila whenever he was in town since ICLARM then had its headquarters in Manila.

Before our reunion in La Crosse, the last time I’d seen Roger and Norma was in Lima in July 2016, when I was the lead author for a review of the center genebanks and their management, and I was visiting CIP. We managed to catch a couple of hours together for pisco sours.

At my hotel in Lima, just after I had arrived from the UK.

As I mentioned, our hotel in La Crosse was right beside the Mississippi, and ‘underneath’ the Big Blue Bridges (actually the Cass Street Bridge and the Cameron Avenue Bridge) that cross from the Minnesota side to Wisconsin.

That got me thinking. The population expansion across the USA in the 19th and 20th centuries involved crossing many rivers, and building many bridges. On the Mississippi alone there are at least 130 bridges along its length. In the Twin Cities alone there are nine major crossings and several minor ones. One of the most impressive is the Smith Avenue or High Level Bridge, from where there is a magnificent view of the St Paul skyline and the river.

As this video pans right, you can first see the magnificent Catholic cathedral, then the white Capitol building, followed by downtown St Paul.

Finally, on our last Thursday in St Paul, we took our grandchildren Callum and Zoë on a relaxing 90 minute river cruise up the Mississippi to the confluence of the Minnesota River with the Mississippi, which is a short distance downriver from where Hannah and Michael live. They tell us that the Fall cruises, when the autumn colors are at their height is a great time to cruise the river.

Chance – but brief – encounters of a special kind

Have you ever bumped into an old acquaintance, even a relative, who you haven’t seen for a long time, just by chance?

This has happened to me on several occasions. The planets must have been in an appropriate alignment.

It was 1969. I was an undergraduate student at the University of Southampton, studying for a BSc degree in Environmental Botany and Geography. On one of the infrequent occasions that I actually used the university library (I burnt the candle at one end more than the other), I was leaving the building on my way to grab a bite to eat, when two young women who I didn’t know asked if I would like to buy a raffle ticket for the city-wide student rag events and charities.

I happily coughed up, and having thanked me, they turned to walk away. But I had to stop them. During our brief encounter, I’d had a very strong feeling that I knew one of them. Not only that, but we were related. How odd. I couldn’t let them walk away without asking.

I turned to the one with very long, almost black hair and asked: ‘Is your surname Jackson?‘ Her jaw dropped, and she replied ‘Yes‘. ‘Then‘, said I, ‘I think your name is Caroline and you’re my cousin [daughter of my dad’s younger brother Edgar]’. And, of course it was Caroline.

I had last seen her around the summer of 1961 or 1962 when my parents and I took our caravan to the New Forest (west of Southampton) and met up with my Uncle Edgar and his wife Marjorie, and cousins Timothy and Caroline.

L-R: Caroline, Timothy, me, and Barley the labrador, and my mum in the background talking to her brother-in-law Edgar, and Marjorie.

It wasn’t until the summer of 2008 that I met her again, when Steph and I joined Caroline’s eldest brother Roger at a special steam event in Wiltshire.

After Southampton, I began my graduate studies in genetic conservation and potato taxonomy at the University of Birmingham. One of my classmates the following academic year, Dave Astley, was, for several years, the research assistant of our joint PhD supervisor, Professor Jack Hawkes.

In January 1973 I joined the International Potato Center (CIP) in Lima, Peru. By August, Steph and I were settled in a larger two bedroom apartment on Avda. Larco in the commercial Miraflores district of Lima, close by the Pacific Ocean. So, the following January, Dave stayed with us for a few days before continuing on to Bolivia where he joined a potato germplasm expedition led by Jack Hawkes.

By 1976, Steph and I had moved to Costa Rica, where I was CIP’s regional leader for Mexico, Central America, and the Caribbean. In early 1980, I was returning from a trip to the Dominican Republic, and transiting overnight in Miami. Joining one of the (interminable) immigration queues, I looked over to my right and, lo and behold to my surprise, Dave was just a couple of passengers ahead of me in the parallel queue. He had just flown in from the UK, on his way to Bolivia, his second expedition there. He had a connecting flight, and once we were both through immigration we only had about 15 minutes to chat before he had to find his boarding gate. What a coincidence!

During that expedition in Bolivia, Dave collected a new species of Solanum that was described by Hawkes and his Danish colleague Peter Hjerting in 1985 and named after Dave as Solanum astleyi (right, from JG Hawkes and JP Hjerting, 1989, The Potatoes of Bolivia, Fig. 22, p. 206. Oxford University Press).

In 1991, I resigned from the University of Birmingham where I had worked for the previous decade as a lecturer in the Department of Plant Biology and joined the International Rice Research Institute (IRRI) in the Philippines as Head of the Genetic Resources Center (GRC)

I made my first visit to China in March 1995, accompanied by one of my colleagues in GRC, Dr Lu Bao-Rong, a Chinese national who had just completed his PhD in Sweden before starting at IRRI in 1993 as a rice taxonomist/cytogeneticist in GRC.

With my colleague, Lu Bao-Rong (middle) on the Great Wall, north of Beijing, and a staff member from the Institute of Botany, Chinese Academy of Sciences.

The first part of our trip took us to Beijing (followed by visits to Hangzhou and Guangzhou). And it was while we were in Beijing that I had my third unexpected encounter.

I think it must have been our last night in Beijing. Our hotel had a very good restaurant serving delicious Sichuan cuisine (Bao-Rong’s native province), and after dining, Bao-Rong and I retired to the hotel bar for a few beers. The bar was on a raised platform with a good view over the hotel foyer and main entrance.

I happened to casually glance towards the foyer and saw, I thought, someone I knew heading for the restaurant. Curiosity didn’t kill the cat, but I had to find out. And sure enough, it was that person: Dr Trevor Williams, who supervised my MSc dissertation on lentils in 1971, and who left the University of Birmingham in 1976 to join the International Board for Plant Genetic Resources (IBPGR) in Rome. The last time I saw Trevor as a Birmingham faculty member was in 1975 when I returned there to complete my PhD dissertation and graduate.

I met him again in 1989 at IBPGR, which had approved a small grant to enable a PhD student of mine from the Canary Islands to collect seeds of a forage legume there as part of his study. And also later that same year when he attended the 20th anniversary celebration of the MSc Course on Conservation and Utilisation of Plant Genetic Resources.

However, by 1990, Trevor had left IBPGR and was working out of Washington, DC, helping to set up the International Network for Bamboo and Rattan (INBAR, now the International Bamboo and Rattan Organization) that was founded in Beijing in 1997. And that’s how our paths came to cross.

Lastly, I had an encounter last year with someone who I hadn’t seen for 63 years.

I was born in Congleton, Cheshire in 1948 and until 1956, when my family moved to Leek (about 12 miles away), my best friend from our toddler years was Alan Brennan who lived a few doors away on Moody Street. Although we made contact with each other in recent years (he found me through this blog) we never met up.

At the end of April last year, Steph and I visited the National Trust’s Quarry Bank mill, just south of Manchester, on our way north from a week’s holiday in the New Forest. Making our way to the mill entrance, we crossed paths with a couple with a dog. I took no notice, but just as we passed, the man called me by name. It was Alan, and his wife Lyn. He recognised me from a recent photo on the blog!

L-R: Steph, me, Alan, and Lyn

Neither of us had too much time to catch up unfortunately. Alan and Lyn were coming to the end of their visit to Quarry Bank (essentially just down the road from Congleton where they still live), and we had yet to look round the cotton mill before completing the remainder of our journey north, around 170 miles. But the planets were definitely lined up on that day. What were the chances that we’d be in the same place at the same time – and actually meet?

So, there you have it. Chance but brief encounters close to home and on the other side of the globe. It really is a small world.
