If it’s Wednesday, it must be Colombia . . .

Not quite the ‘Road to Rio . . .’
I have just returned from one of the most hectic work trips I have taken in a very long time. I had meetings in three countries: Peru, Colombia, and Mexico in just over 6½ days.

And then, of course, there were four days of travel, from Birmingham to Lima (via Amsterdam), Lima to Cali (Colombia), then on to Mexico City, and back home (again via Amsterdam). That’s some going. Fortunately the two long-haul flights (BHX-AMS-LIM and MEX-AMS-BHX) were in business class on KLM. Even so the journeys from Lima to Cali (direct, on Avianca) and Cali to Mexico (via Panama City, on COPA) were 12 hours and 11 hours door-to-door, respectively, the former taking so long because we were delayed by more than 5 hours.

As I have mentioned in an earlier blog post, I am leading the evaluation of the program to oversee the genebank collections in eleven of the CGIAR centers (known as the Genebanks CRP). Together with my team colleague, Marisé Borja, we met with the genebank managers at the International Potato Center (CIP, in Lima), the International Center for Tropical Agriculture (CIAT, in Cali), and the International Maize and Wheat Improvement Center (CIMMYT, in Texcoco near Mexico City).

A drop of cognac.

It all started on Sunday 24 July, when I headed off to Birmingham Airport at 04:30 for a 6 o’clock flight to Amsterdam. Not really having slept well the night before, I can’t say I was in the best shape for flying half way round the world. I had a four hour stopover in Amsterdam, and managed to make myself more or less comfortable in the KLM lounge before boarding my Boeing 777-300 Lima flight sometime after noon. There’s not a lot to do on a long flight across the Atlantic except eat, drink and (try to) sleep. I mainly did the first two.

It never ceases to impress me just how vast South America is. Once we crossed the coast of Venezuela and headed south over the east of Colombia and northern Peru we must have flown for about three hours over rain forest as far as you could see. I wish I’d taken a few pictures of the interesting topography of abandoned river beds and oxbow lakes showing through all that dense vegetation. At one point we flew over a huge river, and there, on its banks, was a city, with an airport to the west. I checked later on Google Maps, and I reckon it must have been Iquitos in northern Peru on the banks of the Amazon. Over 2000 miles from the Atlantic, ocean going ships can sail all the way to Iquitos. I once visited Iquitos in about 1988 in search of cocoa trees, and we crossed the Amazon (about two miles wide at this point) in a small motorboat.

Then the majestic Andes came into view, and after crossing these we began our long descent into Lima, with impressive views of the mountains all the way and, nearer Lima, the coastal fogs that creep in off the Pacific Ocean and cling to the foothills of the Andes.

We landed on schedule at Jorge Chavez International Airport in Lima around 18:00 (midnight UK time) so I had been travelling almost 20 hours since leaving home. I was quickly through Immigration and Customs, using the Preferencial (Priority) line reserved for folks needing special assistance. My walking stick certainly gives me the edge these days on airlines these days.

Unfortunately, the taxi that had been arranged to take me to my hotel, El Condado, in the Lima district of Miraflores (where Steph and I lived in the 1970s) was a no-show. But I quickly hired another through one of the official taxi agencies inside the airport (necessary because of the various scams perpetrated by the cowboy taxi drivers outside the terminal) at half the price of the pre-arranged taxi.

After a quick shower, I met up with old friends and former colleagues at CIP, Dr Roger Rowe and his wife Norma. I first joined CIP in January 1973, and Roger joined in July that same year as CIP’s first head of Breeding & Genetics. He was my first boss!

20160724 001

They were in the bar, and we enjoyed several hours of reminiscences, and a couple of pisco sours (my first in almost two decades), and a ‘lite bite’ in the restaurant. It must have been almost 11 pm before I settled into bed. That was Sunday done and dusted. The work began the following morning.

All things potatoes . . . and more
I haven’t been to CIP since the 1990s. Given the tight schedule of meetings arranged for us, I didn’t get to see much more than the genebank and dining room.

CIP has a genebank collection of wild and cultivated potatoes (>4700 samples or accessions, most from the Andes of Peru), wild and cultivated sweet potatoes (>6400, Ipomoea spp.), and Andean roots and tubers (>1450) such as ulluco (Ullucus tuberosus), mashua (Tropaeolum tuberosum), and oca (Oxalis tuberosa).

20160726 028

Native potato varieties.

Although potatoes are grown annually at the CIP experiment station at Huancayo, some six or more hours by road east of Lima, at over 10,000 feet in the Mantaro Valley, and sweet potatoes multiplied in greenhouses at CIP’s coastal headquarters at La Molina, the collections are maintained as in vitro cultures and, for potatoes at least, in cryopreservation at the temperature of liquid nitrogen. The in vitro collections are safety duplicated at other sites in Peru, with Embrapa in Brazil, and botanical seeds are safely stored in the Svalbard Global Seed Vault.

With a disease pressure from the many diseases that affect potato in its center of origin—fungal, bacterial, and particularly viruses—germplasm may only be sent out of the country if it has been declared free of these diseases. That requires growth in aseptic culture and treatments to eradicate viruses. It’s quite an operation. And the distribution does not even take into account all the hoops that everyone has to jump through to comply with local and international regulations for the exchange of germplasm.

The in vitro culture facilities at CIP are rather impressive. When I worked at CIP more than 40 years ago, in vitro culture was really in its infancy. Today, its application is almost industrial in scale.

Our host at CIP was Dr David Ellis, genebank manager, but we also met with several of the collection curators and managers.

20160725 009

L to R: Ivan Manrique (Andean roots and tubers), Alberto Salas (consultant, wild potatoes), Marisé Borja (evaluation team), me, René Gómez (Senior Curator), David Ellis.

20160725 010

Alberto Salas, now in his 70s, worked as assistant to Peruvian potato expert Prof. Carlos Ochoa. Alberto’s wealth of knowledge about wild potatoes is enormous. I’ve known Alberto since 1973, and he is one of the most humble and kind persons I have ever met.

Prior to our tour of the genebank, René Gómez and Fanny Vargas of the herbarium had found some specimens that I had made during my studies in Lima during 1973 and 1974. I was also able to confirm how the six digit germplasm numbering system with the prefix ’70’ had been introduced and related to earlier designations.

It was great to see how the support from the Genebanks CRP has brought about so many changes at CIP.

Lima has changed so much over the past couple of decades. It has spread horizontally and upwards. So many cars! In the district of Miraflores where we used to live, the whole area has been refurbished and become even smarter. So many boutiques and boutique restaurants. My only culinary regret is that the famous restaurant La Rosa Nautica, on a pier over the Pacific Ocean closed down about two months ago. It served great seafood and the most amazing pisco sours.

All too soon our two days in Lima were over. Next stop: Cali, Colombia.

Heading to the Cauca Valley . . . 
Our Avianca flight to Cali (an Embraer 190, operated by TACA Peru) left on time at 10:25. Once we’d reached our cruising altitude, the captain turned off the seat belt sign, and I headed to the toilet at the front of the aircraft, having been turned away from the one at the rear. Strange, I thought. I wasn’t allowed to use the one at the front either. It seems that both refused to flush. The captain decided to return to Lima, but as we still almost a full load of fuel, he had to burn of the excess so we could land safely. So, at cruising altitude and as we descended, he lowered the undercarriage and flaps to create drag which meant he had to apply more power to the engines to keep us flying, thereby burning more fuel. Down and down we went, circling all the time, for over an hour! We could have made it to Cali in the time it took us to return to Lima. We could have all sat there with legs crossed, I guess.

Once back on the ground, engineers assessed the situation and determined they could fix the sensor fault in about a couple of hours. We were taken back to the terminal for lunch, and around 15:30 we took off again, without further incident.

But as we waited at the departure gate for a bus to the aircraft, there was some impromptu entertainment by a group of musicians.

Unfortunately because of our late arrival in Cali, we missed an important meeting with the CIAT DG, who was not available the following days we were there.

CIAT was established in 1967, and is preparing for its 5oth anniversary next year.

Daniel Debouck, from Belgium, is CIAT’s genebank manager, and he has been there for more than 20 years. He steps down from this position at the end of the year, and will be replaced by Peter Wenzl who was at the Global Crop Diversity Trust in Bonn until the end of April this year. Daniel is an internationally-recognised expert on Phaseolus beans.

The CIAT genebank has three significant collections: wild and cultivated Phaseolus beans (almost 38,000 accessions), wild and cultivated cassava (Manihot spp., >6600 accessions in vitro or as ‘bonsai’ plants), and more than 23,000 accessions of tropical forages. Here’s an interesting fact: one line of the forage grass Brachiaria is grown on more than 100 million hectares in Brazil alone!

Bean varieties.

The bean collections are easily maintained as seeds in cold storage, as can most of the forages. But, like potato, the cassava accessions present many of the same quarantine issues, have to be cleaned of diseases, particularly viruses, and maintained in tissue culture. Cryopreservation is not yet an option for cassava, and even in vitro storage needs more research to optimise it for many clones.

20160729 040

QMS manuals in the germplasm health laboratory.

Like many of the genebanks, CIAT has been upgrading its conservation processes and procedures through the application of a Quality Management System (QMS). A couple of genebanks (including CIP) have opted for ISO certification, but I am of the opinion that this is not really suitable for most genebanks. Everything is documented, however,  including detailed risk assessments, and we saw that the staff at CIAT were highly motivated to perform to the highest standards. In all the work areas, laboratory manuals are always to hand for easy reference.

An exciting development at CIAT is the planned USD18-20 million biodiversity center, with state of the art conservation and germplasm health facilities, construction of which is expected to begin next year. It is so designed to permit the expected thousands of visitors to have good views of what goes on in a genebank without actually having to enter any of the work areas.

On our first night in Cali, our hosts graciously wined and dined us at Platillos Voladores, regarded as one of Cali’s finest restaurants.

1520778_329652313848934_5424856017809772967_n

We had the private room for six persons with all the wine bottles on the wall, which can be seen in this photo above.

Arriba, arriba! Andale!
On Saturday afternoon around 15:30, we headed to Mexico City via Tocumen International Airport in Panama City. Cali’s international airport is being expanded significantly and there are now international flights to Europe as well as the USA. This must be great for CIAT staff, as the airport is only 15 minutes or so from the research center.

After takeoff, we climbed out of the Cauca Valley and had great views of productive agriculture, lots of sugar cane.

  

Tocumen is lot busier than when I was travelling through therein the late 1970s. With several wide-bodied jets getting set to depart to Europe, the terminal was heaving with passengers and there was hardly anywhere to sit down. On our COPA 737-800 flight to Mexico I had chosen aisle seat 5D immediately behind the business class section, so had plenty of room to stretch my legs. Much more comfortable than had I stayed with the seat I was originally assigned. I eventually arrived to CIMMYT a little after midnight.

CIMMYT is the second oldest of the international agricultural centers of the CGIAR, founded in 1966. And it is about to celebrate its 50th anniversary in about 1 month from now. IRRI, where I worked for 19 years, was the first center.

Unlike many of the CGIAR centers that have multi-crop collections in their genebanks (ICARDA, ICRISAT, and IITA for example), CIMMYT has two independent genebank collections for maize and wheat in a single facility, inaugurated in 1996, and dedicated to two renowned maize and wheat scientists, Edwin Wellhausen and Glenn Anderson. But CIMMYT’s most famous staff member is Nobel Peace prize Laureate, Norman Borlaug, ‘Father of the Green Revolution’.

Tom Payne and Denise Costich are the wheat and maize genebank managers. CIMMYT’s genebank has ISO 9001:2008 accreditation.

Ayla Sençer

Tom has been at CIMMYT in various wheat breeding capacities for more than 25 years. In addition to managing the wheat genebank, Tom manages the wheat international nurseries. One of the first curators of the wheat collection was Ayla Sençer from Turkey, and a classmate of mine when we studied at Birmingham in 1970 for the MSc in Conservation and Utilisation of Plant Genetic Resources. The CIMMYT wheat collection is unlike many other germplasm collections in that most of the 152,800 samples are actually breeding lines (in addition to landrace varieties and wild species).

Denise joined CIMMYT just a year or so ago, from the USDA. She has some very interesting work on in situ conservation and management of traditional maize varieties in Mexico and Guatemala. A particular conservation challenge for the maize genebank is the regeneration of highland maizes from South America that are not well-adapted to growing conditions in Mexico. The maize collection comprises over 28,000 accessions including a field collection of Tripsacum (a wild relative of maize).

In recent years has received major infrastructure investments from both the Carlos Slim Foundation and the Bill & Melinda Gates Foundation. New laboratories, greenhouses and the like ensure that CIMMYT is well-placed to deliver on its mission. And the support received through the Genebanks CRP has certainly raised the morale of genebank staff.

On our last day at CIMMYT (Wednesday), we met with Janny van Beem from the Crop Trust. Janny is a QMS expert, based in Houston, Texas, and she flew over to Mexico especially to meet with Marisé and me. When we visiited Bonn in April we only had opportunity to speak by Skype with Janny for jsut 30 minutes. Since the implementation of QMS in the genebanks seems to be one of the main challenges—and success stories—of the Genebanks CRP, we thought it useful to have an in-depth discussion with Janny about this. And very useful it was, indeed!

On the previous evening (Tuesday) Tom, Denise, Marisé, Janny and I went out for dinner in Texcoco, to a well-known tacqueria, then into the coffee shop next door afterwards. No margaritas that night – we’d sampled those on Monday.

20160802 044

L to R: Janny, me, Tom, Marisé, and Denise.

But on this trip we did have one free day, Sunday. And I met up with members of CIMMYT’s Filipino community, many of them ex-IRRI employees, some of who worked in units for which I had management responsibility. They organised a ‘boodle fight‘ lunch, and great fun was had by one and all.

Hasta la vista . . .
At 6 pm on Wednesday I headed into Mexico City to take the KLM flight to Amsterdam. It was a 747-400 Combi (half passengers, half cargo). I haven’t flown a 747 for many years, and I’d forgotten what a pleasant experience it can be. It’s remarkable that the 747 is being phased out by most airlines; they are just not as economical as the new generation twin engine 777s, 787s, and A350s.

With the new seating configuration, I had a single seat, 4E, in the center of the main deck forward cabin. Very convenient. I was glad to have the opportunity of putting my leg up for a few hours. Over the previous 10 days my leg had swelled up quite badly by the end of each day, and it was quite painful. The purser asked if I had arranged any ground transport at Schipol to take me from the arrival to departure gates. I hadn’t, so she arranged that for me before we landed. The distances at Schipol between gates can be quite challenging, so I was grateful for a ride on one of the electric carts.

 

But after we went through security, my ‘assistant’ pushed me to my gate in a wheelchair. I must admit I felt a bit of a fraud. An electric cart is one thing, and most welcome. But a wheelchair? Another was waiting for me on arrival at Birmingham. Go with the flow!

  

20160804 014

I was all alone in Business Class from Schipol to Birmingham. We were back at BHX on time, and I was out in the car park looking for my taxi home within about 20 minutes, and home at 6 pm.

Now the hard work really begins—synthesising all the discussions we had with so many staff at CIP, CIAT, and CIMMYT. For obvious reasons I can’t comment about those discussions, but visiting these important genebanks in such a short period was both a challenging but scientifically enriching experience.

 

 

 

 

Plant Genetic Resources: Our challenges, our food, our future

phillips-jade

Jade Phillips

That was the title of a one day meeting on plant genetic resources organized by doctoral students, led by Jade Phillips, in the School of Biosciences at The University of Birmingham last Thursday, 2 June. And I was honoured to be invited to present a short talk at the meeting.

Now, as regular readers of my blog will know, I began my career in plant genetic resources conservation and use at Birmingham in September 1970, when I joined the one year MSc course on genetic conservation, under the direction of Professor Jack Hawkes. The course had been launched in 1969, and 47 years later there is still a significant genetic resources presence in the School, even though the taught course is no longer offered (and hasn’t accepted students for a few years). Staff have come and gone – me included, but that was 25 years ago less one month, and the only staff member offering research places in genetic resources conservation is Dr Nigel Maxted. He was appointed to a lectureship at Birmingham (from Southampton, where I had been an undergraduate) when I upped sticks and moved to the International Rice Research Institute (IRRI) in the Philippines in 1991.

Potential for genetic diversity conservation – the ‘Fifth Dimension’ – within wider biodiversity protection

I guess there were about 25-30 participants in the meeting, mainly young scientists just starting their careers in plant genetic resources, but with a few external visitors (apart from speakers) from the Millennium Seed Bank at Kew-Wakehurst Place, the James Hutton Institute near Dundee, and IBERS at Aberystwyth.

The meeting grew out of an invitation to Åsmund Asdal from the Nordic Genetic Resources Center (NordGen) to present a School of Biosciences Thursday seminar. So the audience for his talk was much bigger.

asmund

Åsmund is Coordinator of Operation and Management for the Svalbard Global Seed Vault, and he gave a fascinating talk about the origins and development of this important global conservation facility, way above the Arctic Circle. Today the Vault is home to duplicate samples of germplasm from more than 60 depositor genebanks or institutes (including the international collections held in the CGIAR genebank collections, like that at IRRI.

Nigel Maxted’s research group has focused on the in situ conservation and use of crop wild relatives (CWR), although they are also looking at landrace varieties as well. Several of the papers described research linked to the CWR Project, funded by the Government of Norway through the Crop Trust and Kew. Postdocs and doctoral students are looking at the distributions of crop wild relatives, and using GIS and other sophisticated approaches that were beyond my comprehension, to determine not only where there are gaps in distributions, lack of germplasm in genebank collections, but also where possible priority conservation sites could be established. And all this under the threat of climate change. The various PowerPoint presentations demonstrate these approaches—which all rely on vast data sets—much better than I can describe them. So I encourage you to dip into the slide shows and see what this talented group of scientists has been up to.

Neil Munro from Garden Organic described his organization’s approach to rescue and multiply old varieties of vegetables that can be shared among enthusiasts.

n_munro

Seeds cannot be sold because they are not on any official list of seed varieties. What is interesting is that one variety of scarlet runner bean has become so popular among gardeners that a commercial seed company (Thompson & Morgan if I remember what he said) has now taken  this variety and selling it commercially.

julian

Julian Hosking from Natural England gave some interesting insights into how his organization was looking to combine the conservation of genetic diversity—his ‘Fifth Dimension’—with conservation of natural habitats in the UK, and especially the conservation of crop wild relatives of which there is a surprisingly high number in the British flora (such as brassicas, carrot, and onions, for example).

So, what about myself? When I was asked to contribute a paper I had to think hard and long about a suitable topic. I’ve always been passionate about the use of plant genetic diversity to increase food security. I decided therefore to talk about the value of genebank collections, how that value might be measured, and I provided examples of how germplasm had been used to increase the productivity of both potatoes and rice.

m_jackson

Nicolay Vavilov is a hero of mine

Although all the speakers developed their own talks quite independently, a number of common themes emerged several times. At one point in my talk I had focused on the genepool concept of Harlan and de Wet to illustrate the biological value (easy to use versus difficult to use) of germplasm in crop breeding.

Jackson FINAL - Valuing Genebank Collections

In the CWR Project research several speakers showed how the genepool concept could be used to set priorities for conservation.

Finally, there was one interesting aspect to the meeting—from my perspective at least. I had seen the titles of all the other papers as I was preparing my talk, and I knew several speakers would be talking about future prospects, especially under a changing climate. I decided to spend a few minutes looking back to the beginning of the genetic conservation movement in which Jack Hawkes was one of the pioneers. What I correctly guessed was that most of my audience had not even been born when I started out on my genetic conservation career, and probably knew very little about how the genetic conservation movement had started, who was involved, and what an important role The University of Birmingham had played. From the feedback I received, it seems that quite a few of the participants were rather fascinated by this aspect of my talk.

Through hard work, great things are achieved

BirminghamUniversityCrestPer Ardua Ad Alta

That’s the motto of The University of Birmingham, and ‘these sentiments sum up the spirit of Birmingham and illustrate the attitude of the people who have shaped both the city and the University.’

Almost 50 years ago, I had no inkling that I would have more than half a lifetime’s association with this university. Receiving its royal charter in 1900 (although the university was a successor to several institutions founded in the 19th century as early as 1828), Birmingham is the archetypal ‘redbrick university‘, located on its own campus in Edgbaston, about 3 miles southwest of Birmingham city center.


First encounter in 1967

My first visit to the university was in May or June 1967—to sit an exam. Biology was one of the four subjects (with Geography, English Literature, and General Studies) I was studying for my Joint Matriculation Board Advanced Level high school certificate (essentially the university entrance requirement) here in the UK. We were only four or five biology students at my high school, St Joseph’s College in Trent Vale, Stoke-on-Trent (motto: Fideliter et Fortiter).

Now, I don’t remember (maybe I never knew) whether we were too few in number to sit our biology practical exam at the school, or all students everywhere had to attend an examination venue, but we set off by train from Stoke to Birmingham, and ended up at the School of Biological Sciences building. It was a new building then, and the (federal) School had only recently been formed from the four departments of Botany, Zoology & Comparative Physiology, Genetics, and Microbiology.

Just before 2 pm, the five of us—and about 100 other students—trooped into the main laboratory (that I subsequently came to know as the First Year Lab) on the second floor. Little did I know that just over three years later I’d be joining the Department of Botany as a graduate student, nor that 14 years later in 1981 I would join the faculty as Lecturer in Plant Biology. Nothing could have been further from my mind as I settled down to tackle a dissection of the vascular system of a rat, and the morphology of a gorse flower, among other tasks to attempt.

Birmingham was not on the list of universities to which I had applied in December 1966. I’d chosen King’s College, London (geography), Aberystwyth (zoology and geography), Southampton (botany and geography), York (biology), Queen Mary College, London (general biological sciences), and Newcastle (botany and geography). In the end, I chose Southampton, and spent three very happy if not entirely fruitful years there.

Entering the postgraduate world

Jack Hawkes

Jack Hawkes

The next time I visited Birmingham was in February 1970. I had applied to join the recently-founded postgraduate MSc Course on Conservation and Utilization of Plant Genetic Resources. I was interviewed by Course Director and Head of the Department of Botany, Professor JG Hawkes and Senior Lecturer and plant ecologist, Dr Denis Wilkins.

Despite the grilling from both of  them, I must have made an impression because I was offered a place for the following September. The only problem: no support grant. Although Hawkes had applied for recognition by one of the research councils to provide postgraduate studentships, nothing had materialized when I applied (although he was successful the following year, and for many years afterwards providing studentships to British students). So, after graduation from Southampton in July 1970 I was on tenterhooks all summer as I tried to sort out a financial solution to attend the course. Finally, around mid-August, I had a phone call from Hawkes telling me that the university would provide a small support grant. It was only £380 for the whole year, to cover all my living expenses including rent. That’s the equivalent of about £5600 today. The university would pay my fees.

All set then. I found very comfortable bed-sit accommodation a couple of miles from the university, and turned up at the department in early September to begin my course, joining four other students (from Nigeria, Pakistan, Turkey and Venezuela). It was during this one year course that I really learned how to study, and apart from my weekly Morris dancing night, I had few other distractions. It was study, study, study: and it paid off. The rest is history. I graduated in September 1971, by which time I’d been offered a one-year position at the newly-founded International Potato CenterCIP logo (CIP) in Lima, Peru, and I was all set for a career (I hoped) in the world of genetic resources and conservation. As it turned out, my travel to South America was delayed by more than a year during which time I registered for and commenced a PhD study on potatoes, finally landing in Lima in January 1973 and beginning a career in international agricultural research that lasted, on and off, until my retirement in 2010. I carried out most of my PhD research in Peru, and submitted my thesis in October 1975.

Graduation December 1975. L to R: Jack Hawkes (who co-supervised my PhD), me, and Trevor Williams (who became the first Director General of the International Board for Plant Genetic Resources). Trevor supervised my MSc dissertation.

Then I returned to Lima, spending another five years with CIP in Costa Rica carrying out research on bacterial diseases of potatoes among other things.

I should add that during the academic year 1971-72, a young woman, Stephanie Tribble, joined the MSc course. A few months later we became an ‘item’.

Steph’s MSc graduation at the University of Birmingham in December 1972, just weeks before I flew to South America and join the International Potato Center in Lima, Peru.

After graduation, she joined the Scottish Plant Breeding Station just south of Edinburgh, but joined me in Lima in July 1973. We married there in October, and she also had a position with CIP for the years we remained in Lima.

A faculty position
On 1 April 1981 I joined the University of Birmingham as a lecturer in the Department of Plant Biology.

Richard Sawyer

By mid-1980, after almost five years in Costa Rica, I felt that I had achieved as much as I could there, and asked my Director General in Lima, Dr Richard Sawyer, for a transfer to a new position. In November, we moved back to Lima, and I was expecting to be posted either to Brazil or possibly to the Philippines. In the meantime, I had been alerted to a recently-established lectureship in the Department of Plant Biology (formerly Botany) at Birmingham, and had been encouraged to apply¹. With encouragement from Richard Sawyer², and having been invited for interview, I made the trek back to the UK from Lima towards the end of January 1981. The interview process then was very different from what might be expected nowadays. No departmental seminar. Just a grilling from a panel chaired by the late Professor John Jinks, FRS, Dean of the Faculty of Science and head of the Department of Genetics. There were three staff from Plant Biology (Hawkes, Dennis Wilkins, and Brian Ford-Lloyd), and the head of the Department of Biochemistry and Deputy Dean, Professor Derek Walker.

We were three candidates. Each interview lasted about 45 minutes, and we all had to wait outside the interview room to learn who would be selected. I was interviewed last. Joining the other two candidates afterwards, we sat side-by-side, hardly exchanging a word between us, nervously waiting for one of us to be called back in to meet the panel. I was the lucky one. I was offered the position, accepted immediately, and a couple of days later flew back to Lima to break the news and make plans to start a new life with Steph and our daughter Hannah (then almost three) in Birmingham.

Over the 10 years I spent at Birmingham I never had the worry (or challenge) of teaching any First Year Course – thank goodness. But I did contribute a small module on agricultural systems to the Second Year common course (and became the Second Year Chair in the School of Biological Sciences), as well as sharing teaching of flowering plant taxonomy to plant biology stream students mtj-and-bfl-book-launchin the Second Year. With my colleague Brian Ford-Lloyd (with whom I’ve published three books on genetic resources) I developed a Third Year module on genetic resources that seems to have been well-received (from some subsequent feedback I’ve received). I also contributed to a plant pathology module for Third Year students. But the bulk of my teaching was to MSc students on the graduate course on Conservation and Utilization of Plant Genetic Resources – the very course I’d attended a decade earlier. My main focus was crop evolution, germplasm collecting, and agricultural systems, among others. And of course there was supervision of PhD and MSc student research projects.

One of the responsibilities I enjoyed was tutoring undergraduate students, and always had an open door if they needed to see me. It quite shocked me in the late 1990s when my elder daughter, then a student at Swansea University, told me that her tutors had very limited and defined access hours for students. Of course you can’t be on call all day, every day, but you have to be there if a student really need to see you. And my tutees knew that if my office door was open (as it mostly was) they were free to come in and see me.

Once the four departments of the School of Biological Sciences merged into a single department in 1988, I aligned myself with and joined the Plant Genetics Group, and found a better role for myself. I also joined and became Deputy Chair of a cross-disciplinary group called Environmental Research Management (ERM) whose aim was to promote the strength of environment-related research across the university. Through ERM I became acquainted with Professor Martin Parry, and together with Brian Ford-Lloyd we published a book on genetic resources and climate change in 1990, and another in 2014 after we had retired.

Moving on
Even though the prospect of promotion to Senior Lecturer was quite good (by 1989 I’d actually moved on to the Senior Lecturer pay scale), I was becoming somewhat disillusioned with university life by that time. Margaret Thatcher and her government had consistently assaulted the higher education sector, and in any case I couldn’t see things getting any better for some years to come. In this I was unfortunately proved correct. In September 1990 a circular dropped into my post, advertising a new position at the International Rice Research Institute (IRRI) in the Philippines. This was for a germplasm specialist and first head of the Genetic Resources Center. So I applied, was interviewed in January 1991, and accepted the position with a view to joining the institute from 1 July. They actually wanted me to start on 1 April. But as I explained—and IRRI Management accepted—I had teaching and examination commitments to fulfill at the university. In February I began to teach my third year module on genetic resources for the last time, and set the exams for all students to take in May and June. Once the marking and assessments had been completed, I was free to leave.

Friday 28 June was my last day, ending with a small farewell party in the School. I flew out to the Philippines on Sunday 30 June. And, as they say, the rest is history. I never looked back. But now, retirement is sweet, as are my memories.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
¹ Jack Hawkes was due to retire in September 1982 and, recognizing that his departure would leave a big hole in the MSc teaching, the university approved the recruitment of a lecturer in plant genetic resources (with a focus on crop evolution, flowering plant taxonomy, and the like) essentially covering those areas where Jack had contributed.
² Dick Sawyer told me that applying for the Birmingham position was the right thing to do at that stage of my career. However, the day before I traveled to the UK he called me to his office to wish me well, and to let me know whichever way the interview went, he would have a new five-year contract waiting on his desk for me on my return. From my point of view (and I hope CIP’s) it was a win-win situation. Thus I left for the interview at Birmingham full of confidence.

 

How many crop varieties can you name?

Do you ever look at the variety name on a bag of potatoes in the supermarket? I do. Must get a life.

How many potato varieties can you name? Reds? Whites? Or something more specific, like Maris Piper, King Edward, or Desiree to name just three? Or do you look for the label that suggests this variety or that is better for baking, roasting, mashing? Let’s face it, we generally buy what a supermarket puts on the shelf, and the choice is pretty limited. What about varieties of rice? Would it just be long-grain, Japanese or Thai, arboreo, basmati, maybe jasmine? 

When I lived in the Philippines, we used to buy rice in 10 kg bags (although you could buy 25 kg or larger if you so desired). On each, the variety name was printed. This was important because they all had different cooking qualities or taste (or fragrance in the case of the Thai jasmine rice). In Filipino or Thai markets, it’s not unusual to see rice sold loose, with each pile individually labelled and priced, as the two images below show¹:

Today, our rather limited choice of varieties on the shelf does change over time as new ones are adopted by farmers, or promoted by the breeding companies because they have a better flavor, cooking quality, or can be grown more efficiently (often because they have been bred to resist diseases better).

Apples on the other hand are almost always promoted and sold by variety: Golden Delicious, Pink Lady, Granny Smith, Red McIntosh, and Bramley are some of the most popular. That’s because, whether you consciously think about it, you are associating the variety name with fruit color, flavor and flesh texture (and use). But there were so many more apple varieties grown in the past, which we often now describe as ‘heirloom varieties’. Most of these are just not commercial any more.

In many parts of the world, however, what we might consider as heirloom varieties are everyday agriculture for farmers. For example, a potato farmer in the Andes of South America, where the plant was first domesticated, might grow a dozen or more varieties in the same field. A rice farmer in the uplands of the Lao People’s Democratic Republic in Southeast Asia grows a whole mixture of varieties. As would a wheat farmer in the Middle East. There’s nothing heirloom or heritage about these varieties. This is survival.

Heirloom potato varieties still grown by farmers in the Andes of Peru.

An upland rice farmer and her family in the Lao People’s Democratic Republic showing just some of the rice varieties they continue to cultivate. Many Lao rice varieties are glutinous (sticky) and particular to that country.

What’s even more impressive is that these farmers know each of the varieties they grow, what characteristics (or traits) distinguish each from the next, whether it is disease resistant, what it tastes like, how productive it will be. And just as we name our children, all these varieties have names that, to our unsophisticated ears, sound rather exotic.  Names can be a good proxy for the genetic diversity of varieties, but it’s not necessarily a perfect association. In the case of potatoes, for example, I have seen varieties that were clearly different (in terms of the shape and color of the tubers) but having the same name; while other varieties that we could show were genetically identical and looked the same had different names. The cultural aspects of naming crop varieties are extremely interesting and can point towards quite useful traits that a plant breeder might wish to introduce into a breeding program. Some years back, my colleague Appa Rao, I and others published a paper on how and why farmers name rice varieties in the Lao PDR.

In the genebank of the International Rice Research Institute (IRRI) in Los Baños in the Philippines, there are more than 120,000 samples of cultivated rice. And from memory there are at least 65,000 unique names. Are these genetically distinct? In many cases, yes they are. The genebank of the International Potato Center (CIP) in Lima, Peru conserves about 4000 different potato varieties.

What these potato and rice varieties represent (as do maize varieties from Mexico, wheats from the Middle East, soybeans from China, and beans from South and Central America, and many other crops) is an enormous wealth of genetic diversity or, if you prefer, agricultural biodiversity (agrobiodiversity): the genetic resources of the main staple crops and less widely planted crops that sustain human life. The efforts over the past six decades and more to collect and conserve these varieties (as seeds in genebanks wherever possible) provides a biological safety net for agriculture without depriving farmers of the genetic heritage of their indigenous crops. But as we have seen, time and time again, when offered choices—and that’s what it is all about—farmers may abandon their own crop varieties in favor of newly-bred ones that can offer the promise of higher productivity and better economic return. The choice is theirs (although agricultural policy in a number of countries has worked against the continued cultivation of so-called ‘farmer varieties’).

CGIARThank goodness for the genebanks of 11 centers of the global agricultural research partnership that is the Consultative Group on International Agricultural Research (CGIAR). These centers carefully conserve the largest, most important, and genetically-diverse collections of crop germplasm (and forages and trees) of the most important agricultural species. The flow of genetic materials to users around the world is sustained by the efforts of these genebanks under the International Treaty on Plant Genetic Resources for Food and Agriculture. And, of course, these collections have added long-term security because they are duplicated, for the most part, in the long-term vaults of the Svalbard Global Seed Vault¹ deep within a mountain on an island high above the Arctic Circle.

Heritage is not just about conservation. Heritage is equally all about use. So it’s gratifying (and intriguing) to see how IRRI, for example, is partnering with the Philippines Department of Agriculture and farmers in an ‘heirloom rice project‘ that seeks ‘to enhance the productivity and enrich the legacy of heirloom or traditional rice through empowered communities in unfavorable rice-based ecosystems‘ by adding value to the traditional varieties that farmers continue to grow but which have not, until now, been widely-accepted commercially. I gather a project is being carried out by the International Maize and Wheat Improvement Center (CIMMYT) for maize in Mexico that aims to raise the cuisine profile of traditional varieties.

Genetic conservation is about ensuring the survival of heritage varieties (and their wild relatives) for posterity. We owe a debt of gratitude to farmers over the millennia who have been the custodians of this important genetic diversity. It’s a duty of care on which humanity must not renege.

Around the world in 40 years . . . Part 11. Peru: jewel of the Andes

peru_map_outline_titleOver the past few days, I have exchanged some messages on Facebook with the son of a former PhD student of mine from Peru, Dr  Carlos Arbizu. The son, also named Carlos, is currently a PhD student at the University of Wisconsin.

The Arbizu family hails from the fair city of Ayacucho, in the central Andes, almost 600 miles by road southeast of Lima. And it was a photo that Carlos Jr had posted on Facebook recently that made me think about the various travels Steph and I enjoyed around Peru during the two and a half years we lived and worked in Peru. And then I realized that I hadn’t blogged very much about our travels around Peru, although I have posted several stories about our time and work there.

Abra Apacheta

Carlos’ photo was taken at a location known as Abra Apacheta and, as you can see, it’s rather high (map). He confirmed that this place is on the road between Pisco on the coast, and Ayacucho, capital of the Department of the same name further east. But the condition of the road looks significantly better today than in 1974 when Steph and I took our 1600 cc VW Variant on the same trip. I also remember rather a lot of mud somewhere near the top, and great relief when we eventually ploughed through it and reached a slightly firmer road surface on the long descent towards Ayacucho.

I purchased the VW in the UK in September 1972 (for about £1200 tax free), used it for three months, and then it was shipped from Liverpool to Callao. And it served us well for the three years we lived in Peru.

Just a few days after Steph arrived in Peru in early July 1973, we took a day trip up the Santa Eulalia valley near Chosica. This would become one of our favorite short trip destinations.

Steph and I made these long road trips:

  1. Lima-Pisco-Ayacucho-Huancayo-Lima (September 1973)
  2. Lima-Huaraz-Trujillo-Cajamarca-Lima (in June 1974, with our friends John and Marion Vessey)
  3. Lima-San Ramon-Lima (with a day trip by air to Puerto Bermudez, September 1974)
  4. Lima-Arequipa-Puno-Arequipa-Lima (November 1974)

Lima-Pisco-Ayacucho-Huancayo-Lima (map)
to tell the truth, I don’t remember too many details. It seemed like a long climb to the top, and even longer down to Ayacucho. Carlos Arbizu Jr mentioned a duration of 17 hours for the journey. I guess I must have told his father about it once upon a time. Of course Ayacucho became an extremely unsafe place to travel after about 1975 as it was a center of terrorist Sendero Luminoso activity. In 1973 it was a lovely city, with a beautiful Plaza de Armas. The continuation of our journey took us north to Huancayo (location of CIP’s mountain research station) along the valley of the Rio Mantaro. The road was so narrow, with many steep drops into the river below that, in 1973 at least, traffic was only permitted in each direction on alternate days.

Steph was a keen aficionado of cacti, so we had to stop frequently especially on the road north from Ayacucho before we reached the Rio Mantaro valley.

Lima-Huaraz-Trujillo-Cajamarca-Lima (map)
In May 1973 (just a few months after I’d joined CIP), my colleague Zosimo Huaman and I made a month-long collecting trip to the Departments of Ancash and La Libertad. The scenery is stunning, so I had to take Steph there.

19731013005

Marion, Steph, and John on 13 October 1973 – the day Steph and I were married in Miraflores town hall. John and Marion were our witnesses, and we celebrated afterwards at La Granja Azul near Chosica.

And we were joined by our friends John and Marion Vessey (John was a plant pathologist at CIP).

We stayed in Huaraz in the Callejón de Huaylas, and traveled north from there to view the destruction of the earthquake from May 1970 in the former towns of Ranrahirca and Yungay just below Peru’s tallest mountain, Huascarán. We also visited the famous archaeological site at Chavín de Huantar east of Huaraz. It was on that part of the journey that I slammed into a small boulder in the road. I couldn’t see any damage so we continued. The following day as we climbed out of the Callejón de Huaylas towards the coast, i could hear creaking from the rear of the car, and I discovered that one of the shock absorber mountings had been damaged. In fact there was a split, so we limped back into Huaraz to see if it could be repaired. I didn’t have much hope of finding a replacement. Well, as soon as the mechanic had jacked the car up, the mounting split and the wheel almost fell off. With some judicious welding, we were on our way again after a little over an hour. I soon had all the shock absorbers replaced with heavy duty ones.

On the coast, near Casma we visited the archaeological site of Cerro Sechín that has a collection of the most extraordinary carved stones depicting severed heads and the like, obviously the site of a battle.

Battle carvings at Cerro Sechin.

And from the coast, we climbed back up into the Andes to Cajamarca, probably my favorite city in the mountains. It’s not so high, around 2700 m, and has a very pleasant climate. I had visited just a month earlier as part of a three week collecting trip that I made throughout the Department.

Two memories stand out. First, the leche asada (or crème caramel) for which Cajamarca is famous. And the Inca hot baths where we spent a relaxing couple of hours. Cajamarca had in the 1970s a thriving dairy industry. Cajamarca cheese was justly renowned. The British overseas aid had a veterinary team based in Cajamarca, and their offices were located in a renovated ranch house (or finca). The cathedral in the Plaza de Armas was never completed, but the carving of the stonework is exquisite.

Lima-San Ramón-Lima (map)
CIP had a field station on San Ramón (just 770 m altitude), where germplasm was tested for adaptation to warm climates, as well as resistance to various diseases. My work didn’t take me there, so Steph and I decided to go and see for ourselves. The first part of the journey was the same as traveling to Huancayo, but turning north towards Tarma before reaching Huancayo. Tarma is famous for its flower production. The drop down to San Ramón from there is quite spectacular, and it’s quite a sensation to feel the air getting much warmer and more humid as you descend. On one day we drove on to La Merced along the Rio Chanchamayo. On another day we took a light aircraft from San Ramón to the hamlet of Puerto Bermudez on the Rio Pichis, which is apparently the geographical center of Peru. We hired a dugout canoe for a trip upriver, from which there is a great view west towards the escarpment of the east side of the Andes. We faced our return flight with some trepidation. The weather en route was a little stormy, and San Ramón was rained in. There were no seats for us passengers, so we sat on upturned empty beer crates. And our travel companions were several pig carcasses. We lived to tell the tale.

Lima-Arequipa-Puno-Arequipa-Lima (map)
It’s a long drive to Puno, although I’d made the same trip in January that year to carry out field studies at Cuyo-Cuyo. We drove only as far as Arequipa, and then decided to take a communal taxi (or colectivo) for the rest of the trip over the mountains to Puno, which lies at over 4000 m above sea level.

Arequipa is a lovely city and its Plaza de Armas is framed with the  El Misti volcano in the background. The cathedral dates back to the late 17th century. Another site we visited was the Santa Catalina monastery, built almost like a small Spanish village with painted ochre walls.

In Puno we took a trip to the floating islands on Lake Titicaca (the highest navigable lake in the world), inhabited by the Uru people. The beautiful boats made from the totora reeds are used for everyday activities, including school classes, and even growing potatoes. On another day we headed north from Puno to see the Aymara stone towers or chullpas of the Colla people at Sillustani on the shore of Lake Umayo. The chullpas were family tombs, and the stonework is fantastic.

We traveled back to Arequipa to pick up our car, and return to Lima, a journey of two days.

I was lucky to visit Machu Picchu within a week of arriving to Lima in January 1973, and although Steph and I were married in Lima in October that year, we didn’t go away on honeymoon until December, when we visited Cuzco (and Machu Picchu) by air. In Cuzco we visited the famous fortress of Sacsayhuaman.

On the Sunday we went by taxi to the market at Pisac in the Urubamba valley, about 30 km northeast of Cuzco.

Of course I made other trips in the course of my work, and Steph and I regularly traveled to Huancayo for field work, that involved crossing Ticlio, one of the highest passes in the Andes.

The humble spud

Humble? Boiled, mashed, fried, roast, chipped or prepared in many other ways, the potato is surely the King of Vegetables. And for 20 years in the 1970s and 80s, potatoes were the focus of my own research.

The potato (Solanum tuberosum) has something scientifically for everyone: the taxonomist or someone interested in crop diversity, geneticist or molecular biologist, breeder, agronomist, plant pathologist or entomologist, seed production specialist, biotechnologist, or social scientist. So many challenges – so many opportunities, especially since many potatoes are polyploids; that is, they have multiple sets of chromosomes, from 2x=24 to 6x=72.

MTJ collecting cultivated potatoes in 1974Much of my own work – both in the Andes of Peru in the early 70s and once I was back in Birmingham during the 80s – focused on potato genetic resources, understanding the evolutionary dynamics of speciation, and the distribution and breeding value of wild potatoes.

If you’re interested in species diversity, then the potato is the crop for you. In South America there are many indigenous varieties integral to local farming systems at high altitude. Grown alongside other crops such as oca (Oxalis tuberosa) and other Andean tubers of limited distribution, quinoa, and introduced crops such as barley and faba bean (that must have been brought to South America by the Spanish in the 16th century and afterwards). In a recent series on BBC TV (The Inca – Masters of the Cloud), archaeologist and South American expert Dr Jago Cooper repeatedly talked about the wonders of Incan agriculture as one of the foundations of that society yet, disappointingly chose not to illustrate anything of indigenous agriculture today. Farmers still grow potatoes and other crops on the exactly the same terraces that the Incas constructed hundreds of years ago (see my post about Cuyo Cuyo, for example). The continued cultivation of native potato varieties today is a living link with the Incas.

Native varieties of potato from Peru

Native cultivated potatoes are found throughout the Andes from Colombia and Venezuela in the north, south through Ecuador, Peru, Bolivia and Chile, and into northern Argentina. One of the main centres of diversity lies in the region of Lake Titicaca that straddles the border between Peru and Bolivia.

Another important centre of diversity is in the island of Chiloé , southeast of Puerto Montt, a well-known potato growing region of Chile.

The wild tuber-bearing Solanums have a much wider distribution, from the USA south through Mexico and Central America, and widely in South America. And from the coast of Peru to over 4000 m in the high Andes. They certainly have a wide ecological range. But how many wild species are there? Well, it depends who you follow, taxonomy-wise.

SM Bukasob

SM Bukasov

Some of the earliest studies (in the 1930s) were made by Russian potato experts SM Bukasov and SV Juzepczuk, contemporaries of the great geneticist and plant breeder, Nikolai I Vavilov.

In 1938, a young Cambridge graduate, Jack Hawkes (on the left below), visited the Soviet Union to meet with Bukasov (and Vavilov) as he would soon be joining a year-long expedition to the Americas to collect wild and cultivated potatoes. His PhD thesis (under the supervision of Sir Redcliffe Salaman) was one of the first taxonomies of wild potatoes. By 1963, Hawkes had published a second edition of A Revision of the Tuber-Bearing Solanums. By 1990 [1] the number of wild species that he recognized had increased to 228 and seven cultivated ones. Hawkes (and his Danish colleague Peter Hjerting) focused much of their effort on the wild potatoes of the southern cone countries (Argentina, Brazil, Paraguay and Uruguay) [2] and Bolivia [3]. Working at the National Agrarian University and the International Potato Center (CIP) in La Molina, Lima, Peru, potato breeder and taxonomist Carlos Ochoa (on the right below) spent several decades exploring the Andes of his native country, and discovered many new species. But he also produced monographs on the potatoes of Bolivia [4] and Peru [5].

Both Hawkes and Ochoa – rivals to some extent – primarily used plant morphology to differentiate the species they described or recognized, but also using the tools of biosystematics (crossing experiments) and a detailed knowledge of species distributions and ecology.

MTJ and JGH collecting wild potatoes

March 1975, somewhere above Canta in Lima Province. Probably a small population of Solanum multidissectum = S. candolleanum (that now includes S. bukasovii)

I made only one short collecting trip with Jack Hawkes, in March 1975 just before I returned to Birmingham to defend my PhD thesis. Travelling in the Andes between Cerro de Paso, Huanuco and Lima, at one point he asked me to stop our vehicle. “There are wild potatoes near here,” he told me. “To be specific, I think we’ll find Solanum bukasovii”. And within minutes, he had. That’s because Jack had a real feel for the ecology of wild potatoes; he could almost smell them out. I’m sure Carlos Ochoa was just the same, if not more so.

Spooner_David_hs10_9951

David Spooner

The potato taxonomist’s mantle was taken up in the early 1990s by USDA Agricultural Research Service professor David Spooner at the University of Wisconsin. Over two decades, and many field expeditions, he has published an impressive number of papers on potato biology. More importantly, he added molecular analyses to arrive at a comprehensive revision and understanding of the diversity of the tuber-bearing Solanums. In fact, in December 2014, Spooner and his co-authors published one of the most important papers on the biodiversity of wild and cultivated potatoes, recognizing just 107 wild and four cultivated species [6]. For anyone interested in crop evolution and systematics, and potatoes in particular, I thoroughly recommend you take the time to look at their paper (available as a PDF file).

Around the world . . . in 40 years. Part 2. Winter days in Santiago

During the years that I lived in Lima (1973-March 1976) I didn’t visit any other country in South America. However, once I moved to Costa Rica in April 1976, I traveled extensively in Central America, Mexico, and out to the Caribbean islands (more of those in a later posts). And from Costa Rica I also made my first excursions to Brazil and Chile; while I was working in the Philippines, I also got to travel once again to Brazil and Peru on more than one occasion, and also to Caracas, capital of Venezuela.

But let me tell you about a visit to Santiago in Chile during July 1979 while I was working for the International Potato Center (CIP) in Costa Rica.

Nelson Estrada

Nelson Estrada

I was asked by my boss in Lima, Ken Brown, to join a small team (with two CIP colleagues Drs Oscar Malamud and Nelson Estrada, who worked in Lima) to review some of the activities and strategy of the Chilean National Potato Program (INIA, the government agricultural research institute). While the potato growing regions of Chile are south of Santiago, the five day review was scheduled only for office and laboratory visits in the capital.

I flew down to Santiago from San José via Panama City, picking up an overnight LAN Chile flight in Panama. It had just the one stop en route – in Lima, where I had the opportunity of phoning my boss at CIP and telling him I was on the way south. I had traveled down from mid-summer in Costa Rica to mid-winter in Chile, and it was quite a shock to the system. I hadn’t experienced a cold climate for several years, seeing all the trees bare of leaves, and a nip in the air. There were also street vendors roasting chestnuts in Santiago.

Arriving in Santiago around noon, an INIA driver took me to my hotel, and agreed to pick me up later that evening to return to the airport to meet my two Lima-based colleagues, whose flight was arriving at about 8.30 pm. That evening at the airport, I was a little puzzled why it was so busy as there didn’t seem to be many flights departing or arriving.  I decided to go outside and have a look at the airport apron (something you could do in those pre 9-11 days), and I saw there was quite a large crowd, that spontaneously broke into applause. It was then that I saw Chile’s dictator, General Augusto Pinochet, stepping down from his air force plane that had just arrived, and being met by government officials – and a large crowd of fervent Pinochet supporters had gone to the airport to greet him. This was less than six years after he had seized power in a coup that toppled the democratically-elected government of left-wing politician Salvador Allende in September 1973. And we all know what horrors that led to in Chile. But Pinochet’s government was firmly in control in 1979 – everything seemed calm in Santiago.

I don’t actually remember too much about the potato program review – it must have gone quite well, because on the last evening the head of INIA took us all to a very fine restaurant called Enoteca. Now I’ve looked for this restaurant on the web, and it looks like it’s undergone some major changes since I was there more than 30 years ago. The restaurant was also a ‘Chilean wine library’, housed in an old monastery, on a hill overlooking the city. It was  a fantastic view, and the meal was excellent. In the basement, all the wines produced in Chile were on display, available for tasting, and you could then choose one (or more) to have with your meal. Is it now called the Camino Real, on the Cerro San Cristobal in the Parque Metropolitano?

But what I remember most was the entertainment. In those days I spoke quite fluent Spanish – it’s still there in the recesses of my brain, but a little rusty. These two musicians, with guitars, wearing short dark jackets, broad black hats, came into the room and began to sing, moving between the tables, asking for requests, and stopping to chat with the guests around each table. At our table were our Chilean hosts, of course, and my two colleagues and me. What I’ve forgotten to mention is that Oscar and Nelson were Argentinian and Colombian, respectively. The musicians greeted and welcomed each of us, but with Oscar they had some fun. In 1979, tensions were still high as Chile and Argentina had been to the brink of war in 1978 over the Beagle Channel in the far south of both countries.

So‘, says one of the musicians to Oscar, ‘from Argentina, eh? Welcome, welcome. And isn’t it stupid‘, he continued, ‘that two great countries like Chile and Argentina, with very similar traditions and history and background, should be on the verge of war. I have this vision‘ he emphasized, ‘that one day our two nations will be united, and called Chile!

It brought the house down. Doesn’t translate so well into English, but at the time, we almost fell off our chairs we were laughing so much.

There are two other things I remember particularly about this trip. First, I was meandering down one of the main shopping streets when I heard ABBA’s Chiquitita for the first time, emanating from a record store – it had just been released. But my two colleagues didn’t go shopping for souvenirs like me. Instead they headed to the nearest butcher and bought enough beef, securely wrapped in plastic bags, to fill a 20 kg suitcase each. In those days there was a shortage of beef in Lima.

My stay in Chile was all too short. I would love to return, and visit the regions south of Santiago where Chile’s great wines are produced, to visit the potato growing areas around Puerto Montt, and close to one of the centers of origin and diversity of the potato, the Isle of Chiloé, and further south still to the land of snow-capped peaks, glaciers,  and fjords.
