The Birmingham Class of ’71: plant genetic resources pioneers

Pioneers. That’s what we were. Or, at least, that’s what we thought we were.

Five individuals arriving at The University of Birmingham’s Department of Botany in September 1970 to study on the one-year MSc degree course Conservation and Utilization of Plant Genetic Resources (CUPGR).

Professor Jack Hawkes was the Course Leader, supported by Dr Trevor Williams (as Course Tutor) [1].

The MSc course had its first intake (of four students from Canada, Brazil, and the UK) in September 1969. Twenty years later (which was celebrated at the time), hundreds of students had received training in genetic conservation at Birmingham. The course would continue to flourish for a further decade or so, but by the early 2000s there was less demand, limited financial resources to support students, and many of the staff at the university who were the lynch-pins of teaching on the course had moved on or retired.

However, the course had made its impact. There is no doubt of that. Birmingham genetic resources graduates were working all around the world, leading collection and conservation efforts at national levels and, in many cases, helping their countries—and the world—to set policy for the conservation and use of plant genetic resources for food and agriculture (PGRFA). At the FAO conference on PGRFA held in Leipzig, Germany in 1996, for example, about 50 of the national delegations were led by, or had members, who had received training at Birmingham.

The Class of ’71
So, in September 1970, who comprised the second CUPGR cohort? We came from five countries:

  • Felix Taborda-Romero from Venezuela
  • Altaf-ur-Rehman Rao from Pakistan
  • Ayla Sencer from Turkey
  • Folu Dania-Ogbe from Nigeria
  • Mike Jackson (me!) from the UK

Having just graduated a couple of months earlier from the University of Southampton with a BSc degree in Botany and Geography, I was the youngest of the group, just approaching my 22nd birthday. Folu was almost four years my senior, and Ayla was perhaps in her late twenties or early thirties, but I’m not sure. Altaf was 34, and Felix the ‘elder’ of the class, at 38.

I guess Ayla was the only one with a specific genetic resources background, coming to Birmingham from an agricultural research institute near Izmir, and having already been involved with conservation work. Felix and Altaf were both academics. As recent graduates, Folu and I were just starting to think about a career in this new field of plant genetic resources. We wouldn’t be disappointed!

Studying alongside mature students who were not only older than my eldest brother (nine years my senior), but who had taken a year out from their jobs to study for a higher degree, was a novel experience for me. There was also a language barrier, to some extent. Felix probably had the weakest English skills; Ayla had already made some good progress before arriving in Birmingham but she struggled with some aspects of the language. Both Altaf and Folu spoke English fluently as a second language.

We occupied a small laboratory on the north corridor, first floor of the School of Biological Sciences building, just a couple of doors down from where Jack, as Mason Professor of Botany and Head of Department, had his office, and just across from Trevor’s office. In 1981, when I returned to Birmingham as Lecturer in Plant Biology, that same room became my research laboratory for six or seven years.

Folu and myself had desk space on one side of the lab, and the others on the other side. We spent a lot of time huddled together in that room. In order to save us time hunting for literature in the university library, we had access to a comprehensive collection of photocopies of many, if not most, of the scientific papers on the prodigious reading lists given to us.

Richard Lester

We had a heavy schedule of lectures, in crop evolution, taxonomic methods, economic botany (from Dr Richard Lester), population genetics and statistics (from staff of the Department of Genetics), computer programming and data management (in its infancy then), germplasm collection, and conservation, among others. At the end of the course I felt that the lecture load during that one year was equivalent to my three-year undergraduate degree course. We also had practical classes, especially in crop diversity and taxonomy, and at the end of the teaching year in May, we had to sit four written exam papers, each lasting three hours.

There were also guest lectures from the likes of experts like Erna Bennett (from FAO) and Jack Harlan from the University of Illinois.

We also had to choose a short research project, mostly carried out during the summer months through the end of August, and written up and presented for examination in September. While the bulk of the work was carried out following the exams, I think all of us had started on some aspects much earlier in the academic year. In my case, for example, I had chosen a topic on lentil evolution by November 1970, and began to assemble a collection of seeds of different varieties. These were planted (under cloches) in the field by the end of March 1971, so that they were flowering by June. I also made chromosome counts on each accession in my spare time from November onwards, on which my very first scientific paper was based.

At the end of the course, all our work, exams and dissertation, was assessed by an external examiner (a system that is commonly used among universities in the UK). The examiner was Professor Norman Simmonds, Director of the Scottish Plant Breeding Station (SPBS) just south of Edinburgh [2]. He made his scientific reputation working on bananas and potatoes, and published several books including an excellent text on crop evolution [3].

Then and now
So how did we all end up in Birmingham, and what happened after graduation?

Felix received his first degree in genetics (Doutor em Agronomia) in 1955 from the Escola Superior de Agricultura Luiz de Queiroz, Universidade de São Paulo in Brazil. He was a contemporary of Almiro Blumenschein, who went on to collaborate with geneticist and Nobel Laureate Barbara McLintock on the maizes of South America, and head the Brazilian agricultural research institute EMBRAPA (which is the parent organization for the Brazilian national genebank CENARGEN).

Returning to Venezuela, Felix was involved (from 1956-1961) with a national project to breed the first Venezuelan hybrid corns and to organize commercial seed production while also looking after a collection of local varieties and races of corn.

In 1961 he started to work in the Facultad de Agronomía at the Universidad del Zulia, now one of the largest and most important universities in Venezuela. It seems he found out about the Birmingham course in 1969 through contact with Dr Jorge León, a Costarrican botanist working for IICA who had also been worked at FAO in genetic resources, and was a contemporary of Jack Hawkes in the 1960s genetic resources movement. León is second from right, standing, in the photo below. But Felix had also been inspired towards plant genetic resources by the book Plants, Man and Life by American geneticist Edgar Anderson.

Felix self-financed his studies at Birmingham, having taken a sabbatical leave from his university, and arriving in Birmingham by the middle of August. In December 1970, Felix returned briefly to Venezuela to bring his young wife Laura and his newly-born son Leonardo to Birmingham. They took up residence in a house owned by Jack Hawkes in Harborne, a suburb close to the university.

His dissertation, on the effect on growth of supra-optimal temperatures on a local Venezuelan sorghum variety, was supervised by plant physiologist Digby Idle. Having been awarded his MSc (the degree was conferred in December 1971), Felix returned to his university in Maracaibo, and continued his work in sorghum breeding. He was one of the pioneers to introduce grain sorghums in Venezuela, and continued working at the university up until about five years ago when, due to the deteriorating economic and social situation in his native country, Felix and Laura (who has an MSc degree from Vanderbilt University) decided to move to Florida and enjoy their retirement there. His three sons and six grandchildren had already left Venezuela.

Felix and I made contact with each other through Facebook, and it has been wonderful to catch up with him after almost five decades, and to know that since his Birmingham days he has enjoyed a fruitful career in academia and agricultural research, and remains as enthusiastic today, in his mid-eighties, as he was when I first knew him in September 1970.

Altaf was born in Faisalabad in December 1936, and when he came to Birmingham in 1970 he was already Assistant Professor in the Department of Botany at the University of Agriculture in Faisalabad. He had received his BSc (Agric.) degree from that university in 1957, followed by an MSc (Agric.) in 1962.

I cannot remember the topic of his dissertation nor who supervised it, perhaps Richard Lester. After graduation he moved to Bangor University to complete a PhD in 1974 on the genetic variation and distribution of Himalayan wheats and barleys, under the supervision of Professor John Witcombe (from whom I obtained the various photos of Altaf). In 1974 he joined a joint Bangor University-Lyallpur University to collect wheats and barley in northern Pakistan.

He continued his teaching at Faisalabad until 1996 when he retired as Professor of Botany. But he wasn’t finished. He joined the Cholistan Institute of Desert Studies at Islamia Universty and was director from 1998 to 2000. Sadly, in December 2000, just four days after his 64th birthday, Altaf passed away, leaving a wife, two daughters and four sons. Remembered for his devotion to plant genetic resources and desert ecology, you can read his obituary here.

Genetic resources conservation in Turkey received a major boost in the mid-1960s when an agreement was signed between the Government of Turkey and the United Nations Special Fund to establish a ‘Crop Research and Introduction Centre‘ at Menemen, Izmir. The Regional Agricultural Research Institute (ARARI, now the Aegean Agricultural Research Institute) became the location for this project, and Ayla was one of the first scientists to be involved.

Ayla came to Birmingham with a clear focus on what she wanted to achieve. She saw the MSc course as the first step to completing her PhD, and even arrived in Birmingham with samples of seeds for her research. During the course she completed a dissertation (with Jack Hawkes) on the origin of rye (Secale cereale), and she continued this project for a further two years or so for her PhD. I don’t recall whether she had the MSc conferred or not. In those days, it was not unusual for someone to convert an MSc course into the first year of a doctoral program; I’m pretty sure this is what Ayla did.

Completing her PhD in 1973 or 1974, Ayla continued to work with the Turkish genetic resources program until 1981 when she accepted a position at the International Maize and Wheat and Improvement Center (CIMMYT) near Mexico City, as the first curator of the center’s wheat collection.

I believe Ayla stayed at CIMMYT until about 1990 or so, and then returned to Turkey. I know that she has retired with her daughter to a small coastal town southwest from Izmir, but I’ve been unable to make contact with her directly. The photo below was sent to me by Dr Tom Payne who is the current curator of CIMMYT’s wheat collection. He had dinner with Ayla a couple of years ago during one of his visits to Turkey.

Folu married shortly before traveling to Birmingham. Her husband had enrolled for a PhD at University College London. He had seen a small poster about the MSc course at Birmingham on a notice board at the University of Ibadan, Nigeria where Folu had completed her BSc in Botany. She applied successfully for financial support from the Mid-Western Nigeria Government to attend the MSc course, and subsequently her PhD studies.

Dr Dennis Wilkins

Before coming to Birmingham, Folu had not worked in genetic resources, but had a flair for genetics. Like me, she hoped that the course would be a launch pad for an interesting career. Her MSc dissertation—on floating rice—was supervised Dr Dennis Wilkins, an ecophysiologist. In the late 70s and early 80s, Dennis supervised the PhD of World Food Prize Laureate Monty Jones, who is now the Minister of Agriculture, Forestry and Food Security in Sierra Leone.

After completing her MSc, Folu began a PhD under the supervision of Trevor Williams on the taxonomy of West African rice, which she completed in 1974. To successfully grow her rice varieties, half of one glasshouse at the department’s garden at Winterbourne was successfully converted to a rice paddy.

In this photo, taken during her PhD studies, Folu’s mother (who passed away in January 2018) visited her in Birmingham. Folu can’t remember the three persons between her and her mother, but on the far left is Dr Rena Martins Farias from Brazil, who was one of the first cohort of MSc students in 1969.

Folu also had the opportunity of joining a germplasm collecting mission to Turkey during 1972. In this photo, Folu (on the right) and Ayla (on the left) are collecting wheat landrace varieties.

Returning to Nigeria, Folu joined the Department of Plant Biology at the University of Benin, Benin City until 2010, when she retired. She taught a range of courses related to the conservation and use of plant genetic resources, and conducted research on the taxonomy of African crop plants, characterization of indigenous crops from West Africa, and the ethnobotany of useful indigenous African plants. She counts among her most important contributions to genetic resources the training courses she helped deliver, and the research linkages she promoted among various bodies in Nigeria. She has published extensively.

After retirement from the University of Benin, she was seconded to the new Samuel Adegboyega University at Ogwa in Edo State, where she is Professor and Dean of the College of Basic and Applied Sciences. She has three children and five grandchildren.

As for myself, I was the only member of our class to be interviewed for a place on the MSc course, in February 1970. I’d heard about it from genetics lecturer at Southampton, Dr Joe Smartt, who stopped me in the corridor one day and gave me a pamphlet about the course, mentioning that he thought this would be right up my street. He wasn’t wrong!

However, my attendance was not confirmed until late August, because Jack Hawkes was unable to secure any financial support for me until then.

Trevor Williams supervised my dissertation on the origin of lentil (Lens culinaris), but as early as February 1971, Jack Hawkes had told me about an opportunity to work in Peru for a year after I’d completed the course, looking after a germplasm collection of native potato varieties at the newly-established International Potato Center (CIP) in Lima. In October 1971 I began a PhD (under Jack’s supervision) on the relationships between diploid and tetraploid potatoes (which I successfully defended in October 1975), and joined CIP in January 1973. Continuing with my thesis research, I also made several potato collecting missions in different regions of Peru.

From 1976-1981 I continued with CIP as its regional research leader in Central America, based in Costa Rica, working on disease resistance and potato production. I spent a decade back at The University of Birmingham from April 1981, mainly teaching on the genetic resources MSc course, carrying out research on potatoes and legumes, and supervising PhD students.

In 1991, I joined the International Rice Research Institute (IRRI) at Los Baños in the Philippines as the first head of the Genetic Resources Center, looking after the International Rice Genebank, and managing a major project to collect and conserve rice genetic resources worldwide. In 2001, I gave up research, left the genebank, and joined IRRI’s senior management team as Director for Program Planning and Communications, until 2010 when I retired.

But I’ve not rested on my laurels. Since retirement, I’ve organized two international rice science conferences for IRRI in Vietnam and Thailand, co-edited a second book on genetic resources and climate change, and led a review of the CGIAR’s genebank program.

My wife Steph is a genetic resources graduate from Birmingham, in 1972, and she joined me at CIP in July 1973 after leaving her position at the Scottish Plant Breeding Station where she helped to curate the Commonwealth Potato Collection (CPC).

We have two daughters, Hannah and Philippa (both PhD psychologists), and four grandchildren.

Sitting (L to R): Callum, Hannah, Zoe, Mike, Steph, Elvis, Felix, and Philippa. Standing: Michael (L) and Andi (R).

Looking back at the past five decades, I think I can speak for all of us that we had successful careers in various aspects of the conservation and use of plant genetic resources, repaying the investments supporting us to study at Birmingham all those years ago. What a journey it has been!

How long is a piece of string?

Just three decades after Spanish conquistador Francisco Pizarro first encountered the potato in the high Andes of Peru in 1532, the potato was already being grown in the Canary Islands. And it found its way to mainland Europe via the Canaries shortly afterwards [1].

The first known published illustration of the potato in Gerard’s Herball of 1597.

The potato was described by English herbalist John Gerard in his Herball published in 1597. In a revised version, published in 1633 over 20 years after his death, there is another beautiful woodcut of the potato, referred to Battata Virginiana or Virginian potatoes.

Potatoes became an important crop by the late 18th century, and particularly the staple of Ireland’s impoverished citizens in the years leading up to the Irish Potato Famine of the mid-1840s.

Today, potatoes are one of the world’s most important crops, grown in every continent except Antarctica. Known scientifically as Solanum tuberosum, it was given this name by the famous Swedish naturalist, Carl Linnaeus in his 1753 magnum opus, Species Plantarum.

The potato and its wild relatives must be one of the most studied groups of crop plants. Not that I’m biased (having researched potatoes for more than 20 years).

Potato diversity and germplasm collections
Its clear that there is a wealth of information about the diversity within the section of the genus Solanum that encompasses the potato. They have been studied extensively from a taxonomic point of view, breeding efforts worldwide have incorporated genes from many wild species to enhance productivity, and important germplasm collections were set up decades ago to preserve this important diversity, to study it, and use it in potato breeding.

My former colleague (and fellow PhD student at Birmingham), Dr Zosimo Huaman, describes the management of CIP’s wild potato collection in Huancayo to members of the CGIAR’s Inter-Center Working Group on Genetic Resources who held their annual meeting at CIP in 1996.

Among the most important collections are held at:

The wild relatives of the potato have one of the broadest geographical and ecological ranges among species that have been domesticated for human consumption. While the various forms of cultivated potatoes were domesticated in the Andes of Peru and Bolivia, and on the coast of Chile, the wild species are found from the southwest USA (in the coniferous forests of Arizona, for instance) through Mexico and the countries of Central America to Panama, along the Andes south to Chile and northern Argentina, and south and east on to the plains of Argentina, Brazil, Paraguay and Uruguay. Wild species are found in the coastal desert of Peru, in the cloud forests of central America to almost 3000 m, at the highest altitudes of the Andes, well over 4000 m, and also growing in the highly humid transition zone on the eastern side of the Andes dropping down to the lowland forests (known as the ‘eyebrow of the mountain’ or ceja de la montaña).

Here is just a very small sample of the diversity—and beauty—of wild potato species (photos courtesy of my friends at the Commonwealth Potato Collection).

How many potato species are there?
Well, it depends, to some extent, on one’s perspectives as a taxonomist, use of different species concepts, and the methods used to study species diversity, and also on the work that earlier taxonomists published.

Essentially, there are three basic taxonomic approaches:

  • Morphology: often based on the study of dried herbarium specimens collected in the wild. In the case of potatoes, this has led to the description of a multiplicity of species, with almost every variant being described as a separate species. This reliance on plant morphology was the approach taken by the 19th and early 20th century botanists.
  • Biosystematics: takes an experimental view of species diversity, of breeding behaviour and relationships, and very much based on collections in the field and the study of ecology, and growing samples in a uniform environment such as the study one of my PhD students, Susan Juned, made of Solanum chacoense, a species from Argentina and Paraguay.
  • Molecular biology: methods have become available in the last couple of decades to analyse the most basic variation in DNA, and helped to refine further how potato taxonomists view the diversity within the tuber-bearing Solanums, and the relationships between species.

While these different approaches still do not provide a definitive answer to the question of how many species there are, we know that taxonomists have described and named more than 200 species. To some extent it’s like asking how long is a piece of string. And that helps me to provide an analogy.

Take a piece of string. If you were to view this string along its length that, to your vision would be fore-shortened, it would be very difficult to say with any degree of certainty just how long the string actually was. However, if you increase the angle at which you view the string, until you are looking at right angles, your ability to estimate its length also increases. At right angles you can see the whole length, and measure it accurately in many different ways.

Taxonomic study is a bit like looking at the string from different angles. Each taxonomist builds on earlier studies, and describing new species or subsuming previously described ones into another species (as merely variants). This is one of the challenges of studying wild potato species: they are highly variable and show considerable phenotypic (or morphological) plasticity. It’s not always possible to study large numbers of plants under uniform conditions to reduce the variation caused by differences in habitats.

The 2n=3x=36 chromosomes of a triploid potato, from a root-tip squash in two cells.

Furthermore potatoes have considerable chromosomal variation, with a base number of x=12, with diploids (2n=24) the most frequent, and mostly self-incompatible (i.e. they cannot self fertilise), infertile triploids (2n=36, including two cultivated species), tetraploids with 2n=48 (mostly self-fertile, and including the cultivated Solanum tuberosum of world-wide agriculture), some pentaploids (2n=60; including one cultivated form), and a few hexaploids with 2n=72. Wild potatoes are uncommonly promiscuous when grown together under experimental conditions, and will inter-cross readily (they are bee-pollinated), yet hybrids often do not survive beyond the second generation in the wild. Many species are separated by ecology, and generally do not come into contact with each other, thus maintaining their species identity.

Nevertheless, this is what makes the study of potatoes and wild species so very interesting, and that captured my interest directly for over two decades, and continues to do so, even though I moved on to the study of other crops like rice and grain legumes.

The potato taxonomists
Many botanists have taken an interest in wild potatoes. During the 19th century, the Swiss-French botanist Alphonse de Candolle (d. 1893) named a number of species, as did François Berthault (d. 1916). But the first decades of the 20th century leading up to the Second World War saw a lot of collecting and taxonomic description. In Germany, Friedrich August Georg Bitter, who specialised in the genus Solanum, described and named many species. However, it was the involvement of several Russian botanists and geneticists, under the leadership of Nicolai Vavilov, that saw an expansion in the collection of potatoes throughout the Americas, but a systematic evaluation of this germplasm leading to even more species being described.

SM Bukasov

Two names come to mind, in particular: SM Bukasov and VS Juzepczuk. They were active during the 1920s and 30s, taking part in several missions to South America, and developing further the concept of potato species. But much of their work was based on morphological comparison leading to the identification of even small variants as new species.

In August 1938, a young Cambridge graduate, Jack Hawkes, traveled to Leningrad in Russia to meet and discuss with Bukasov and Juzepczuk (and Vavilov himself) in preparation for the 1938-39 British Empire Potato Collecting Expedition to South America (which Jack has described in his 2004 memoir Hunting the Wild Potato in the South American Andes [2]).

A young Jack Hawkes (second from right) stands outside a church near Lake Titicaca in northern Bolivia, alongside expedition leader Edward Balls (second from the left).

Jack Hawkes

That collecting expedition, and the subsequent studies (which led to Hawkes being awarded his PhD from the University of Cambridge in 1941 for a thesis Cytogenetic studies on South American potatoes supervised by renowned potato scientist Sir Redcliffe N Salaman), was the launch pad, so to speak, of potato taxonomy research for the rest of the 20th century, in which Hawkes became one of the leading exponents.

After Cambridge, Hawkes spent some years in Colombia (where he no doubt continued his studies of wild potatoes) but it was on his return to the UK in 1952 when appointed to a lectureship in the Department of Botany at The University of Birmingham (where he was to remain until his retirement in 1982) that his potato studies flourished, leading him to publish in 1956 his first taxonomic revision of the tuber-bearing Solanums (with a second edition appearing in 1963).

In 1990, he published his final synopsis of the tuber-bearing Solanums [3]; that taxonomic treatment is the one followed by the curators of the Commonwealth Potato Collection.

Jack’s approach to potato taxonomy was based on a thorough study of morphology backed up by rigorous crossing experiments, and a cytogenetic and sometimes serological evaluation of species relationships.

I first met Jack in February 1970 when he interviewed me for a place on his newly-founded MSc course on plant genetic resources, joining the course later that same year. In September 1971 I became one of Jack’s PhD students, joining others who were looking at the origin and evolution of the cultivated species [4].

Donovan S CorrellIn these revisions he was also taking into account the work of US botanist, Donovan S Correll who published his own potato monograph in 1962 [5], as well as three important South American botanists with whom he would collaborate from time-to-time: Professor César Vargas from the National University of Cuzco; Professor Martín Cárdenas from Cochabamba in Bolivia; and Professor Carlos Ochoa, originally from Cuzco, who was a professor at the Universidad Nacional Agraria (UNA) in La Molina, Lima and, around 1975 or so, joined the International Potato Center across the street from the UNA.

Vargas published a number of species descriptions in the 1950s, but made his most significant contribution in his two part monographs, Las Papas Sudperuanas published in 1949 and 1956. I met Vargas on a couple of occasions, first in January 1973 just after I’d joined CIP as Associate Taxonomist. And a second time in February 1974 when I was passing through Cuzco with Dr Peter Gibbs from the University of St Andrews in Scotland. Peter was making a study of incompatibility among different forms of the Andean tuber crop, oca (Oxalis tuberosa), and had joined me on an excursion to Cuyo-Cuyo in the Department of Puno. Vargas’s daughter Martha was studying for her MSc degree under Peter’s supervision at St Andrews.

It was Carlos Ochoa, however, whose studies of potatoes and their relatives rivalled (and in some respects eclipsed) those of Jack Hawkes. They were quite intense taxonomic rivals, with a not-altogether harmonious relationship at times. Carlos certainly played his taxonomic cards very close to his chest.

Me consulting with Carlos Ochoa concerning the identity of some triploid potatoes, in one the screenhouses at the International Potato Center in 1974.

But the fact that he grew up in the Andes and had, from an early age, taken an interest in the diversity of this quintessential Andean crop and its wild relatives, led him to dedicate his life to uncovering the diversity of potatoes in his homeland. He was also a potato breeder and released some of the most important varieties in Peru, such as Renacimiento, Yungay, and Tomasa Condemayta.

In this video (in Spanish, and broadcast on Peruvian TV on his death in 2008) he talks about his early life in Cuzco, the pressures on him to study medicine or become a lawyer, and how he found his true vocation: the study of wild potatoes.

Setting potato taxonomy and germplasm exploration priorities at CIP
Forty-five years ago this week, CIP convened the first planning workshop on the exploration and taxonomy of potatoes [6], inviting a group of taxonomists and potato breeders to meet in Lima and mull over the ‘state of play’ taking into consideration what taxonomic research had already been accomplished, what was in the pipeline, and what CIP’s germplasm exploration policy (especially in Peru) should be. I attended that meeting (as an observer), having landed in Lima just a few days earlier.

On the taxonomic side were Jack Hawkes, Carlos Ochoa, and Donald Ugent who was a ethnobotany professor at Southern Illinois University in Carbondale. Richard Tarn, a potato breeder from Agriculture Canada at Fredericton, New Brinswick, had completed his PhD under Jack’s supervision at Birmingham. Frank Haynes, a professor of genetics and potato breeder at North Carolina State University (and long-time friend and colleague of CIP’s first Director General, Richard Sawyer) and Roger Rowe [7], then curator of the USDA’s potato collection at Sturgeon Bay (who would join CIP in July 1973 as the Head of Breeding and Genetics, and become my PhD co-supervisor) were the other participants.

In 1969, Jack had published (with his Danish colleague Peter Hjerting [8]) a monograph of the potatoes of southern cone countries of South America [9], and by the time of the CIP 1973 workshop was well into research on the potatoes of Bolivia [10], leading publication of a monograph in 1989.

What I’ve never been able to fathom after all these years is why Ochoa decided to write his own monograph of the Bolivian species rather than concentrating in the first instance on the Peruvian species. Nevertheless Ochoa did produce his own fine monograph in 1990 [11], beautifully illustrated with some fine watercolours by CIP plant pathologist Franz Frey. This was followed by an equally magnificent volume on the potatoes of Peru in 2004 [12], also illustrated by Frey.

Throughout his expeditions and research, Ochoa was supported by several assistants, the most notable being Ing. Alberto Salas. Now in his mid-70s, he has been collecting wild potatoes for five decades.

I knew Alberto when I first joined CIP in 1973, and it was a delight to meet him again (although he had retired) during my visit to CIP in July 2016.

Taking up the baton
With retirement, Hawkes and Ochoa passed the potato taxonomy baton to a new generation of researchers, principally David Spooner, a USDA scientist at the University of Wisconsin-Madison who made several collecting trips throughout the Americas.

David Spooner

David’s research took potato systematics to a new level, employing the developing molecular and genomic approaches, and use of different classes of markers to help him refine his understanding of the diversity of the tuber-bearing Solanums, building of course on the very solid Hawkes and Ochoa foundations.

Although no longer working on potatoes (his most recent focus on carrots supported the PhD thesis of Carlos Arbizu, Jr, the son of one of my PhD students at Birmingham in the 1980s), David’s scientific output on potatoes has been prodigious. With molecular insights supporting more traditional methods he has proposed a 50% reduction in the number of potato species from the more than 200 listed in Hawkes’s 1990 publication.

Is this the end of the potato taxonomy story? Probably for the time-being. It’s unlikely that anyone will pursue these studies to the same depth as Hawkes and Hjerting, Ochoa, or Spooner. Nevertheless, as the curators of the Commonwealth Potato Collection have done, most potato researchers will take a pragmatic approach and fix on a particular taxonomic treatment on which to base their management or use of germplasm. Taxonomy is one of those disciplines in which subjective interpretations (obviously based on empirical studies of diversity) can lead to contrary classifications. What is a distinct species to one taxonomist may be merely a variant to another. Undoubtedly these different taxonomic treatments of the tuber-bearing Solanums have permitted us to have a much better appreciation of just how long ‘the potato piece of string’ really is.

While I was at IRRI, he was based in Cairo working for the CGIAR center that became WorldFish (with its headquarters in Penang, Malaysia). Before it moved to Malaysia, ICLARM as it then was had its offices in Manila, and we would see Roger in the Philippines from time-to-time.

When I was at Birmingham in the 1980s I had two PhD students, Lynne Woodwards and Ian Gubb who studied this species because its tubers lack so-called enzymatic blackening, a trait that could be very useful in potato breeding.

Laos – jewel in the rice biodiversity crown

From 1995 to late 2000, the International Rice Research Institute (IRRI) through its Genetic Resources Center (GRC, now the TT Chang Genetic Resources Center) coordinated a project to collect and conserve the genetic diversity of rice varieties that smallholder farmers have nourished for generations in Asia and Africa. The collecting program also targeted many of the wild species relatives of cultivated rice found in those continents as well as Latin America.

With a grant of more than USD3 million from the Swiss Agency for Development Cooperation (SDC) the project made significant collections of rice varieties and wild species at a time when, in general, there was a moratorium on germplasm exploration worldwide. The Convention on Biological Diversity had come into force at the end of December 1993, and many countries were developing and putting in place policies concerning access to germplasm. Many were reluctant to allow access to non-nationals, or even exchange germplasm internationally. It’s not insignificant then that IRRI was able to mount such a project with the full cooperation of almost 30 countries, and many collecting expeditions were made, many of them including IRRI staff.

As Head of GRC from 1991 to 2001, I developed the project concept and was responsible for its implementation, recruiting several staff to fill a number of important positions for germplasm collection, project management, and the research and training components. I have written about the project in more detail elsewhere in this blog.

One of the most important strategic decisions we took was to locate one staff member, Dr Seepana Appa Rao, in Laos (also known as the Lao People’s Democratic Republic) where IRRI already managed the Lao-IRRI project for the enhancement of the rice sector. This project was also funded by the SDC, so it was a natural fit to align the rice germplasm activities alongside, and to some extent within, the ongoing Lao-IRRI Project.

The leader of the Lao-IRRI Project was Australian agronomist, Dr John Schiller, who had spent about 30 years working in Thailand, Cambodia and Laos, and whose untimely death was announced just yesterday¹.

Until Appa Rao moved to Laos, very little germplasm exploration had taken place anywhere in the country. It was a total germplasm unknown, but with excellent collaboration with national counterparts, particularly Dr Chay Bounphanousay (now a senior figure in Lao agriculture), the whole of the country was explored and more than 13,000 samples of cultivated rice collected from the different farming systems, such as upland rice and rainfed lowland rice. A local genebank was constructed by the project, and duplicate samples were sent to IRRI for long-term storage as part of the International Rice Genebank Collection in GRC. Duplicate samples of these rice varieties were also sent to the Svalbard Global Seed Vault when IRRI made its various deposits in that permafrost facility inside the Arctic Circle.

Of particular interest is that Lao breeders immediately took an interest in the collected germplasm as it was brought back to the experiment station near the capital Vientiane, and multiplied in field plots prior to storage in the genebanks. There are few good examples where breeders have taken such an immediate interest in germplasm in this way. In so many countries, germplasm conservation and use activities are often quite separate, often in different institutions. In some Asian countries, rice genebanks are quite divorced from crop improvement, and breeders have no ready access to germplasm samples.

Appa Rao was an assiduous rice collector, and spent weeks at a time in the field, visiting the most remote localities. He has left us with a wonderful photographic record of rice in Laos, and I have included a fine selection below. We also published three peer-reviewed papers (search for Appa Rao’s name here) and seven of the 25 chapters in the seminal Rice in Laos edited by John and others. 

The rices from Laos now represent one of the largest components (maybe the largest) of the International Rice Genebank Collection. Many are unique to Laos, particularly the glutinous varieties.

¹ Yesterday, I received an email from one of my former IRRI colleagues, Professor Melissa Fitzgerald who is now at the University of Queensland, with the very sad news that John Schiller had been found in his apartment just that morning. It’s believed he had passed away due to heart failure over the course of the weekend.

I first met John in November 1991, a few months after I’d joined IRRI. He and I were part of a group of IRRI scientists attending a management training course, held at a beach resort bear Nasugbu on the west coast of Luzon, south of Manila. The accommodation was in two bedroom apartments, and John and I shared one of those, so I got to know him quite well.

Our friendship blossomed from 1995 onwards when we implemented the rice biodiversity project, Appa Rao was based in Vientiane, and I would travel there two or three times a year. In February 1997, I had the opportunity of taking Steph with me on one trip, and that coincided with the arrival of another IRRI agronomist, Bruce Linquist (with his wife and small son) to join the Lao-IRRI Project. We were invited to the Lao traditional welcoming or Baci ceremony at John’s house, for the Linquists and Steph. I’d already received this ceremony on my first visit to Laos in 1995 or 1996.

John also arranged for Appa and Chay to show Steph and me something of the countryside around Vientiane. Here were are at the lookout over the Ang Nam Ngum Lake, just north of the capital, where we took a boat trip.

L to R: Mrs Appa Rao, Appa, Kongphanh Kanyavong, Chay Bounphanousay, Steph, and me.

After he retired from IRRI, John moved back to Brisbane, and was given an honorary fellowship at the University of Queensland. He continued to support training initiatives in Laos. As he himself said, his heart was with those people. But let John speak for himself.

My other close colleague and former head of IRRI’s Communication and Publications Services, Gene Hettel, overnight wrote this eloquent and touching obituary about John and his work, that was published today on the IRRI News website. Just click on the image to read this in more detail.

 

Learning about crop wild relatives

Much of my work with plant genetic resources has concerned the conservation and use of landrace varieties, of potatoes and rice.

Diversity in potatoes and rice

Yes, I have done some work with wild species, and helped occasionally with collection of wild species germplasm. In terms of research, I managed an active group of scientists at IRRI in the Philippines working on the biosystematics of rice (mainly AA genome species relationships). I also had undergraduate and postgraduate students work on the wild species of Lathyrus and potatoes during the years I taught at The University of Birmingham.

I made just one short collecting trip with Jack Hawkes in early 1975, into the Andes of Central Peru to find wild potatoes. That was a fascinating trip. He knew his potato ecology; he could almost smell them. On returning to the UK in 1981, I joined my colleague Brian Ford-Lloyd to collect wild beets in the Canary Islands, and some years later assisted one of my PhD students, Javier Francisco-Ortega, to collect seeds of a forage legume in Tenerife. I wrote about these two collecting trips recently.  I also helped to collect some wild rices during a visit to Costa Rica in the late 1990s but, in the main, orchestrated a major germplasm collecting program while leaving the actual collecting to my other colleagues in IRRI’s Genetic Resources Center.

One of my teaching assignments at Birmingham was a 10-week module, two or three classes a week plus plus an afternoon practical, on crop diversity and evolution. Many of the world’s most important crops such as wheat and barley, and a plethora of legume species such as lentil, chickpea, and faba bean originated in the so-called Fertile Crescent of the Middle East. Apart from a couple of short trips to western Turkey, I had limited experience of Mediterranean environments where these crops were domesticated. I’ve since been in Syria a couple of times in the 1990s.

That was all rectified in at the end March-early April 1982¹ when I had the good fortune to participate in a course—two weeks long if my memory serves me well—in Israel, organized by Profs. Gideon Ladizinsky and Amos Dinoor of the Hebrew University of Jerusalem, at the Rehovot campus near Tel Aviv.

Gideon Ladizinsky explains the ecology of wild lentils (or is that wild chickpea?) while Amos Dinoor looks on.

I recall that the course was funded (or at least supported in part) by the International Board for Plant Genetic Resources (IBPGR). Among the other participants were several MSc students, class of 1981-82, from The University of Birmingham attending the Conservation and Utilization of Plant Genetic Resources course in the Department of Plant Biology. Not all the students of that intake could take up the invitation to travel to Israel. Those from Bangladesh, Malaysia, and Indonesia for example were not permitted (under their national laws) to visit Israel, even though an invitation had been extended to all students regardless of nationality, and the Israeli authorities would have issued visas without a stamp in their passports.

I don’t remeber all the other participants. We must have been half a dozen or so from Birmingham, plus Bruce Tyler from the Welsh Plant Breeding Station (now part of the Institute of Biological, Environmental and Rural Sciences, IBERS, at Aberystwyth University), George Ayad from IBPGR, Zofia Bulinska-Radomska and one of her colleagues from the National Centre for Plant Genetic Resources, IHAR, near Warsaw, Poland, Luis Gusmão from Portugal (who attended a short course at Birmingham), and others whose names I cannot remember.

Bruce Tyler, from the WPBS. An inveterate smoker, one of Bruce’s comments on almost anything was ‘He’s a cracker!’

We stayed at a kibbutz near to Rehovot, and were quite comfortable there. It was a short drive each day into the campus for the classroom activities, some lectures and practical classes. But we also made excursions from the north to the south of the country, and east to the Dead Sea to find crop wild relatives in their native habitats. I wonder, 35 years on, how many of those habitats exist. We travelled freely between Israel and parts of what are now the Palestine Authority controlled West Bank.

We had opportunity of seeing these wild relatives in what was essentially a living laboratory. Both Gideon and Amos, experts in their fields of crop diversity and domestication, and disease epidemiology in wild species, respectively, used many of these wild populations for their research and of their students.

My eyes were opened to the important role of ecology in these seasonally dry-wet landscapes, often on limestone, and the differences to be found between north- and south-facing slopes. I unfortunately no longer have some of the photos I took during that trip of the populations of wild barley, Hordeum spontaneum, that grew over large swathes of the landscape, looking to all intents and purposes like a field of cultivated barley. It was in populations like these, and of wild oats that Amos Dinoor studied the dynamics of disease spread and resistance.

Gideon had a wonderful way of linking species in different habitats, how they maintained they biological identity, often through flowering at different times of the day. I remember on one occasion as we walked through a mixture of oat species with different chromosome numbers, or ploidy. I asked Gideon the time, but he didn’t look at his watch. Instead, he picked a panicle of one of the oats alongside the path, and replied ‘It’s about 4:15 pm’. Then he looked at his watch. It was almost 4:15 pm! He was so familiar with the ecology of these species that, under defined conditions, he could predict when different species would flower. Remarkable! On the coast, south of Tel Aviv, we did look at disease in different wild species. I certainly learned a great deal from this course, and discussing crop evolution and domestication with these experts from the Fertile Crescent, and others like Daniel Zohary (who had published on the origin of lentils about the same time as me in the mid-1970s; he passed away in December 2016). Among the young scientists we met was Dani Zamir who pioneered the use of enzymes, or isozymes,to study the diversity of crops and their wild relatives, tomatoes in his case.

There was one interesting episode during the course. When teaching crop evolution to my Birmingham students, I encouraged them to analyse the evidence presented to account for the origin and evolution of different crop species, often based on conflicting hypotheses. So, it was natural for them to ask questions at the end of each lecture, and even question the interpretations they had heard. After just one or two sessions, and much to the consternation of my students, the ‘professors’ refused to take any questions. As I explained to my group, their hosts had worked on a range of species in depth, and were convinced that their interpretations were the correct (and only?) ones to be believed.  My students hadn’t been impolite or ‘aggressive’ in their questioning, just keen to explore more ideas.

We did also have opportunities for sight-seeing, around Jerusalem and to the Dead Sea, as well as understand some more about irrigation agriculture for which Israeli scientists and engineers had become renowned.

Genetic resources in safe hands

Among the most important—and most used—collections of plant genetic resources for food and agriculture (PGRFA) are those maintained by eleven of the fifteen international agricultural research centers¹ funded through the Consultative Group on International Agricultural Research (CGIAR). Not only are the centers key players in delivering many of the 17 Sustainable Development Goals (SDGs) adopted by the United Nations in 2015, but their germplasm collections are the genetic base of food security worldwide.

Over decades these centers have collected and carefully conserved their germplasm collections, placing them under the auspices of the Food and Agriculture Organization (FAO), and now, the importance of the PGRFA held by CGIAR genebanks is enshrined in international law, through agreements between CGIAR Centers and the International Treaty on Plant Genetic Resources for Food and Agriculture (ITPGRFA)². These agreements oblige CGIAR genebanks to make collections and data available under the terms of the ITPGRFA and to manage their collections following the highest standards of operation.

Evaluation and use of the cultivated and wild species in these large collections have led to the development of many new crop varieties, increases in agricultural productivity, and improvements in the livelihoods of millions upon millions of farmers and poor people worldwide. The genomic dissection of so many crops is further enhancing access to these valuable resources.

The CGIAR genebanks
In the Americas, CIP in Peru, CIAT in Colombia, and CIMMYT in Mexico hold important germplasm collections of: potatoes, sweet potatoes and other Andean roots and tubers; of beans, cassava, and tropical forages; and maize and wheat, respectively. And all these collections have serious representation of the closest wild species relatives of these important crops.

In Africa, there are genebanks at Africa Rice in Côte d’Ivoire, IITA in Nigeria, ILRI in Ethiopia, and World Agroforestry in Kenya, holdings collections of: rice; cowpea and yams; tropical forage species; and a range of forest fruit and tree species, respectively.

ICARDA had to abandon its headquarters in Aleppo in northern Syria, and has recently relocated to two sites in Morocco and Lebanon.

ICRISAT in India and IRRI in the Philippines have two of the largest genebank collections, of: sorghum, millets, and pigeon pea; and rice and its wild relatives.

There is just one CGIAR genebank in Europe, for bananas and plantains, maintained by Bioversity International (that has its headquarters in Rome) at the University of Leuven in Belgium.

Genebank security
Today, the future of these genebanks is brighter than for many years. Since 2012 they received ‘secure’ funding through the Genebanks CGIAR Research [Support] Program or Genebanks CRP, a collaboration with and funding from the Crop Trust. It was this Genebanks CRP that I and my colleagues Brian Ford-Lloyd and Marisé Borja evaluated during 2016/17. You may read our final evaluation report here. Other background documents and responses to the evaluation can be found on the Independent Evaluation Arrangement website. The CRP was superseded by the Genebank Platform at the beginning of 2017.

As part of the evaluation of the Genebanks CRP, Brian Ford-Lloyd and I attended the Annual Genebanks Meeting in Australia in November 2016, hosted by the Australian Grains Genebank at Horsham, Victoria.

While giving the Genebanks CRP a favorable evaluation—it has undoubtedly enhanced the security of the genebank collections in many ways—we did call attention to the limited public awareness about the CGIAR genebanks among the wider international genetic conservation community. And although the Platform has a website (as yet with some incomplete information), it seems to me that the program is less proactive with its public awareness than under the CGIAR’s System-wide Genetic Resources Program (SGRP) more than a decade ago. Even the folks we interviewed at FAO during our evaluation of the Genebanks CRP indicated that this aspect was weaker under the CRP than the SGRP, to the detriment of the CGIAR.

Now, don’t get me wrong. I’m not advocating any return to the pre-CRP or Platform days or organisation. However, the SGRP and its Inter-Center Working Group on Genetic Resources (ICWG-GR) were the strong foundations on which subsequent efforts have been built.

The ICWG-GR
When I re-joined the CGIAR in July 1991, taking charge of the International Rice Genebank at IRRI, I became a member of the Inter-Center Working Group on Plant Genetic Resources (ICWG-PGR), but didn’t attend my first meeting until January 1993. I don’t think there was one in 1992, but if there was, I was not aware of it.

We met at the campus of the International Livestock Centre for Africa (ILCA)³ in Addis Ababa, Ethiopia. It was my first visit to any African country, and I do remember that on the day of arrival, after having had a BBQ lunch and a beer or three, I went for a nap to get over my jet-lag, and woke up 14 hours later!

I’m not sure if all genebanks were represented at that ILCA meeting. Certainly genebank managers from IRRI, CIMMYT, IITA, CIP, ILCA, IPGRI (the International Plant Genetic Resources Institute, now Bioversity International) attended, but maybe there were more. I was elected Chair of the ICWG-PGR as it was then, for three years. These were important years. The Convention on Biological Diversity had been agreed during June 1992 Earth Summit in Rio de Janeiro, and was expected to come into force later in 1993. The CGIAR was just beginning to assess how that would impact on its access to, and exchange and use of genetic resources.

We met annually, and tried to visit a different center and its genebank each year. In 1994, however, the focus was on strengthening the conservation efforts in the CGIAR, and providing better corrdination to these across the system of centers. The SGRP was born, and the remit of the ICWG-PGR (as the technical committee of the program) was broadened to include non-plant genetic resources, bringing into the program not only ICLARM (the International Centre for Living Aquatic Resources Management, now WorldFish, but at that time based in Manila), the food policy institute, IFPRI in Washington DC, the forestry center, CIFOR in Indonesia, and ICRAF (the International Centre for Research on Agro-Forestry, now World Agroforestry) in Nairobi. The ICWG-PGR morphed into the ICWG-GR to reflect this broadened scope.

Here are a few photos taken during our annual meetings in IITA, at ICRAF (meetings were held at a lodge near Mt. Kenya), and at CIP where we had opportunity of visiting the field genebanks for potatoes and Andean roots and tubers at Huancayo, 3100 m, in central Peru.

The System-wide Genetic Resources Program
The formation of the SGRP was an outcome of a review of the CGIAR’s genebank system in 1994. It became the only program of the CGIAR in which all 16 centers at that time (ISNAR, the International Services for National Agricultural Research, based in The Hague, Netherlands closed its doors in March 2004) participated, bringing in trees and fish, agricultural systems where different types of germplasm should be deployed, and various policy aspects of germplasm conservation costs, intellectual property, and use.

In 1995 the health of the genebanks was assessed in another review, and recommendations made to upgrade infrastructure and techical guidelines and procedures. In our evaluation of the Genebanks CRP in 2016/17 some of these had only recently been addressed once the secure funding through the CRP had provided centers with sufficient external support.

SGRP and the ICWG-GR were major players at the FAO International Technical Conference on Plant Genetic Resources held in Leipzig in 1997.

Under the auspices of the SGRP two important books were published in 1997 and 2004 respectively. The first, Biodiversity in Trust, written by 69 genebank managers, plant breeders and others working with germplasm in the CGIAR centers, and documenting the conservation and use status of 21 species or groups of species, was an important assessment of the status of the CGIAR genebank collections and their use, an important contribution not only in the context of the Convention on Biological Diversity, but also as a contribution to FAO’s own monitoring of PGRFA that eventually led to the International Treaty in 2004.

The second, Saving Seeds, was a joint publication of IFPRI and the SGRP, and was the first comprehensive study to calculate the real costs of conserving seed collections of crop genetic resources. Costing the genebanks still bedevils the CGIAR, and it still has not been possible to arrive at a costing system that reflects both the heterogeneity of conservation approaches and how the different centers operate in their home countries, their organizational structures, and different costs basis. One model does not fit all.

In 1996/97 I’d been impressed by some research from the John Innes Institute in the UK about gene ‘homology’ or synteny among different cereal crops. I started developing some ideas about how this might be applied to the evaluation of genebank collections. In 1998, the ICWG-GR gave me the go-ahead—and a healthy budget— to organize an international workshop on Genebanks and Comparative Genetics that I’d been planning. With the help of Joel Cohen at ISNAR, we held a workshop there in ISNAR in August 1999, and to which we invited all the genebank managers, staff working at the centers on germplasm, and many of the leading lights from around the world in crop molecular biology and genomics, a total of more than 50 participants.

This was a pioneer event for the CGIAR, and certainly the CGIAR genebank community was way ahead of others in the centers in thinking through the possibilities for genomics, comparative genetics, and bioinformatics for crop improvement. Click here to read a summary of the workshop findings published in the SGRP Annual Report for 1999.

The workshop was also highlighted in Promethean Science, a 41 page position paper published in 2000 on the the importance of agricultural biotechnology, authored by former CGIAR Chair and World Bank Vice-President Ismail Serageldin and Gabrielle Persley, a senior strategic science leader who has worked with some of the world’s leading agricultural research and development agencies. They address address the importance of characterizing biodiversity (and the workshop) in pages 21-23.

Although there was limited uptake of the findings from the workshop by individual centers (at IRRI for instance, breeders and molecular biologists certainly gave the impression that us genebankers has strayed into their turf, trodden on their toes so-to-speak, even though they had been invited to the workshop but not chosen to attend), the CGIAR had, within a year or so, taken on board some of the findings from the workshop, and developed a collective vision related to genomics and bioinformatics. Thus, the Generation Challenge Program (GCP) was launched, addressing many of the topics and findings that were covered by our workshop. So our SGRP/ICWG-GR effort was not in vain. In fact, one of the workshop participants, Bob Zeigler, became the first director of the GCP. Bob had been a head of one of IRRI’s research programs from 1992 until he left in about 1998 to become chair of the Department of Plant Pathology at Kansas State University. He returned to IRRI in 2004 as Director General!

Moving forward
Now the Genebanks CRP has been superseded by the Genebank Platform since the beginning of the year. The genebanks have certainly benefited from the secure funding that, after many years of dithering, the CGIAR finally allocated. The additional and external support from the Crop Trust has been the essential element to enable the genebanks to move forward.

In terms of data management, Genesys has gone way beyond the SGRP’s SINGER data management system, and now includes data on almost 3,602,000 accessions held in 434 institutes. Recently, DOIs have been added to more than 180,000 of these accessions.

One of the gems of the Genebanks CRP, which continues in the Genebank Platform, is delivery and implementation of a Quality Management System (QMS), which has two overarching objectives. QMS defines the necessary activities to ensure that genebanks meet all policy and technical standards and outlines ways to achieve continual quality improvement in the genebank’s administrative, technical and operational performance. As a result, it allows genebank users, regulatory bodies and donors to recognize and confirm the competence, effectiveness and efficiency of Platform genebanks.

The QMS applies to all genebank operations, staff capacity and succession, infrastructure and work environments, equipment, information technology and data management, user satisfaction, risk management and operational policies.

The Platform has again drawn in the policy elements of germplasm conservation and use, as it used to be under the SGRP (but ‘ignored’ under the Genebanks CRP), and equally importantly, the essential elements of germplasm health and exchange, to ensure the safe transfer of germplasm around the world.

Yes, I believe that as far as the CGIAR genebanks are concerned, genetic resources are in safe(r) hands. I cannot speak for genebanks elsewhere, although many are also maintained to a high standard. Unfortunately that’s not always the case, and I do sometimes wonder if there are simply too many genebanks or germplasm collections for their own good.

But that’s the stuff of another blog post once I’ve thought through all the implications of the various threads that are tangled in my mind right now.

Beets, ‘beans’, and Canaries

Lying off the Atlantic coast of northwest Africa by less than 600 miles, the Canary Islands archipelago comprises seven large islands, and a small group of islets off the north coast of Lanzarote, the island that lies furthest east and north. Volcanic in origin, and arid for the most part, their flora comprises many interesting endemic species found only on the Atlantic islands of MacaronesiaI’ve visited the Canaries twice, both in the 1980s, to collect plant germplasm (and also take a family holiday). Both expeditions were funded by the International Board for Plant Genetic Resources (IBPGR, now Bioversity International, based in Rome, Italy). So, as someone who studied potatoes and rice (and some legumes) most of my career, how did I become involved with collecting germplasm in the Canaries?

Brian Ford-Lloyd

Searching for beets
After leaving the International Potato Center in March 1981, I arrived at The University of Birmingham to begin my decade-long teaching career as Lecturer in Plant Biology from 1 April. Almost immediately, my colleague and fellow lecturer, Brian Ford-Lloyd (who retired a few years back as Emeritus Professor of Plant Conservation Genetics) invited me to join him on a collecting trip to the Canaries to look for wild relatives of beets (Beta spp.) that would contribute to an IPBGR global initiative on beet germplasm.

Now while I had my own experiences of germplasm collecting of cultivated (and some wild) potatoes in the Andes of South America between 1973 and 1976, I had no experience of beets whatsoever. Brian was keen to have me along on the trip because I did have one very important skill: I spoke (quite) fluent Spanish, and he expected that our Canarian counterparts would speak little English (which turned out to be more or less correct). So, not only would I be an experienced pair of germplasm hands, I could also be interpreter-in-chief.

Fortunately the dates for the trip coincided with my personal timetable then. Having arrived back in the UK at the end of March, my wife Steph (and daughter Hannah) stayed with her parents in Essex while I settled into my new job at the university, and while we house hunted. By the time Brian and I headed off to the Canaries in June, we’d bought our house, but moving in was not scheduled until the first or second weeks of July. So this was a great opportunity for me to join Brian.

Trevor Williams

Brian completed his PhD in 1973 under the supervision of Trevor Williams, submitting a thesis on the biosystematics of the genus Beta. As part of that research he made a collecting trip throughout Turkey in the early 1970s; and subsequently he maintained his research interest and activity in beets. Collecting in the Canaries was part of an IBPGR global initiative on beets.

Our particular interest there was a group of three beet species of Beta Sect. Patellares (I’m not sure if, or how, the taxonomy of Beta has changed in the intervening years) native to the archipelago, little represented at that time in different germplasm collections. Beets were reported from a range of localities throughout the islands, most often around the coasts or in ruderal habitats, but rarely inland (except in Fuerteventura) where the terrain is too high. In any case, this beet germplasm was considered under threat of genetic erosion, and had to be collected before habitats were lost through expansion of tourist resorts and holiday homes. Brian tells me he has been back to some of the sites where we collected and they have indeed been lost in this way.

Arnoldo Santos-Guerra

Travelling to the Canaries from Elmdon Airport (now Birmingham Airport) via London and Madrid, our first stop was Gran Canaria, staying for a couple of nights at the Jardín Botánico Canario Viera y Clavijo, where British botanist Dr David Bramwell was the director (and his wife Zoë, an acclaimed botanical artist). Those first days were essentially to find our feet, take some advice from David on where best to collect, before heading off to the island of Fuerteventura, the next island east from Gran Canaria, where we would meet our local expert and collaborator, Dr Arnoldo Santos-Guerra of the Centro Regional de Investigación y Tecnología Agrarias, Tenerife. For the collections in Tenerife, La Palma, and La Gomera we were joined by Arnoldo’s colleague, Lic. Manuel Fernández-Galván.

L-R: Brian, Arnoldo, Manuel, and me

In all, we collected 93 samples of beets from 52 locations on five islands: Gran Canaria, Fuerteventura, Tenerife, La Palma, and La Gomera.  Afterwards we published a trip report¹ in the FAO/IBPGR Plant Genetic Resources Newsletter.

On Tenerife, La Palma, and particularly La Gomera, there are precipitous inclines from the main roads down to the ocean’s edge. Deeply dissected landscapes ensure that wild beet populations are isolated from one another, even over relatively short distances as the cliff coastlines project into the ocean, with coves and beaches in between, where beets were often found. Therefore our ability to collect beet samples was quite often dependent entirely upon accessibility to the beach. The photos below were taken in Fuerteventura, Tenerife, and La Gomera. In some of them you can see the level of urbanization, almost 40 years ago, in many localities that were suitable environments for wild beets. The housing and tourist developments must be many times greater today.

But the actual process of collecting was not difficult at all, and seeds were often sampled from most if not all plants in some populations. Wild beets have a prostrate habit, and the ‘seeds’ were often found, in abundance, underneath the living plants. It was then just a question of scooping up handfuls of the seeds into a collecting bag, and annotating the collecting information appropriately.

I say ‘seeds’, but the morphology of beets is a little more complex than that. Actually what we collected were small fruits with a hard pericarp, with several joined together to form multigerm seedballs. Modern sugar beet varieties are monogerm, a trait discovered in a wild beet species, in the former Soviet Union (Ukraine, in fact) during the 1930s . Because of their impermeability to moisture, and also due to the arid environments in which these beets species grew, we were confident that we were collecting viable seeds. In fact, as Brian explained to me, beet seeds are quite difficult to germinate.

On our return to Birmingham, the seeds were added to the Birmingham Beta Collection that Brian curated, and other collections that are part of the World Beta Network. One recipient was Lothar Frese in Germany, now at the Julius Kühn-Institut in Quedlinburg. This germplasm has been used in a variety of studies looking at disease resistance such as Cercospora leaf spot resistance in B. procumbens in particular, and there has been much work since in terms of genetic mapping for resistance. After Brian retired, his beet collection was passed to the Genetic Resources Unit at the Warwick Crop Centre for safe storage.

A beet -‘bean’ linkage
In addition to beets, we collected 11 samples of other crops, among which was just one sample of a shrub or tree fodder legume, tagasaste, from La Palma, classified botanically as Chamaecytisus palmensis, and cultivated by many farmers. In our trip report, referred to above, we commented that the species did seem to be quite variable and, given its wider potential as a fodder legume, we suggested that it would warrant further study.

Javier Francisco-Ortega

And that was the last I thought about tagasaste until six years later when a young Spanish student from Tenerife, Javier Francisco-Ortega, enrolled on the genetic resources MSc course at Birmingham. Thirty years ago this month! I supervised Javier’s MSc dissertation on chromosome variation in Lathyrus pratensis, one of around 150 species in a genus that also contains the commonly-grown garden sweetpea, L. odoratus, and the edible grasspea L. sativus that was one of my research interests during the 1980s.

Anyway, to cut a long story short, Javier was an outstanding student, and began a PhD project with me in October 1988 on the ecogeography of the tagasaste complex, now classified taxonomically as C. proliferus. Only the forms from La Palma are popularly known as tagasaste (the ‘C. palmensis‘ we’d seen in La Palma in 1981), whereas those from the rest of the archipelago are commonly called escobón.

Morphological variants of tagasaste and escobón, Chamaecytisus proliferus

Tagasaste is the only form which is broadly cultivated in the Canary Islands and, since the late 19th century, also in New Zealand and Australia (particularly as fodder for sheep and goats). It has also become naturalized in Australia (South Australia, New South Wales, Victoria and Tasmania), Java, the Hawaiian Islands, California, Portugal, North Africa, Kenya, Tanzania and South Africa.

When I resigned from the university in June 1991 to join the International Rice Research Institute in the Philippines, supervision of Javier’s PhD passed to Brian.

In Spring and Summer 1989, and with funding from IBPGR, Javier began a systematic survey of 184 tagasaste and escobón populations throughout the archipelago (all islands except Fuerteventura and Lanzarote which are too dry), taking herbarium samples from each for morphological study, and revisited later to collect seeds. I joined Javier in July to assist with the collection of seeds from the Tenerife populations. Our trip report² was published in Plant Genetic Resources Newsletter in 1990. Arnoldo Santos-Guerra and Manuel Fernández-Galván were also contributors to this work.

Escobón populations are found commonly growing in gullies among pine forests, and appear to thrive here where there is the ever-present expectation (and danger) of forest fires. Indeed periodic burning appears to support the maintenance of escobón populations. These photos show the habitats of escobón populations in Tenerife, and Javier and myself making collections.

While more common in La Palma, farmers in Tenerife grow a few bushes of tagasaste in their terraces (seen on the right edge of the field in the picture below) on the north-facing slopes of the Teide volcano sloping down to the Atlantic.

We deposited duplicate seed samples in the Spanish national genebank in Madrid, and also in Tenerife. Javier took seeds back to Birmingham for further study, especially for analysis of molecular variation. Besides his PhD thesis, submitted successfully in 1992, his research led to several other scientific papers on morphological variation, phytogeography, ecogeographical characterization, genetic diversity, and the history of origin and distribution.

After he completed his PhD at Birmingham, Javier took postdoctoral fellowships at Ohio State University and the University of Texas at Austin before returning to Tenerife for a couple of years. In 1999 he was appointed Assistant Professor in the Department of Biological Sciences at Florida International University in Miami. He became Full Professor in 2012. He also has a joint appointment at the Fairchild Tropical Garden just south of Miami, as head of the Fairchild Plant Molecular Systematics Laboratory, with a special interest in cycads and palms, as well as an abiding interest in island floras. He has maintained his links with Arnoldo Santos-Guerra and David Bramwell.

In this video, Javier talks about his interests and the impact of his botanical research.

In the blink of an eye, it seems, 50 years have passed

The first week of October 1967. 50 years ago, to the day and date. Monday 2 October.

I was setting off from my home in north Staffordshire to the port city of Southampton on the the UK’s south coast (via London for a couple of nights), to begin a three year BSc Combined Honours degree course in [Environmental] Botany and Geography at the university. I was about to become a Freshman or ‘Fresher’. Not only anticipating being away from home for the first time (although I’d always been sort of independent), I was looking forward to the excitement of ‘Freshers’ Week’ to make new friends, discovering new activities to take up.

On the afternoon of Wednesday 4 October, I joined the ‘Freshers’ Special’ from Waterloo Station in London, a train chartered by the Students’ Union, and met several fellow students in the same compartment who remained close friends throughout my time at Southampton. Unlike mainline rail services, our train stopped at the small suburban station at Swaythling, and hordes of Freshers were disgorged on to the platform and into buses to take them to their respective Hall of Residence, several of which were close-by.

I’d accepted a place in South Stoneham House (becoming Vice President of the Junior Common Room in my second year in autumn 1968), comprising a sixteen floor tower (now condemned for habitation as there’s a lot of asbestos) alongside a rather elegant Queen Anne mansion built in 1708.

I later discovered that the grounds had been landscaped by Capability Brown. Quite a revelation considering my interest in these things nowadays associated with my membership of the National Trust. It’s sad to know what has happened to South Stoneham in the last decade or so.

I had a room on the sixth floor, with a view overlooking Woodmill Lane to the west, towards the university, approximately 1.2 miles and 25 minutes away on foot. In the next room to mine, or perhaps two doors away, I met John Grainger who was also signed up for the same course as me. John had grown up in Kenya where his father worked as an entomologist. Now that sounded quite exotic to me.

Over the course of the next couple of days, I met the other students who had enrolled for Combined Honours as well as single honours courses in botany or geography, and others who were taking one of these as a two-year subsidiary or one-year ancillary subject.

We were five Combined Honours students: Stuart Christophers from Devon, Jane Elliman from Stroud in Gloucestershire, another whose name was Michael (I forget his surname; he came from Birmingham), John and me. Failing his exams at the end of the first year in early summer 1968, Michael was asked to withdraw, as were about one third of the botany class, leaving fewer than twenty students to head off to an end-of-year field course in Co. Clare, Ireland.

Middle row: Nick Lawrence (crouching), Alan Mackie, Margaret Barran, Diana Caryl, John Jackson (Zoology with Botany subsidiary), Stuart Christophers. Front row: Jill Andison, Janet Beasley, Patricia Banner, Mary Goddard, Jane Elliman, Chris Kirby.

As ‘Combined’ students we had, of course, roots in both departments, and tutors in both as well: Dr Joyce ‘Blossom’ Lambert (an eminent quantitative ecologist) in Botany, and Dr Brian Birch, among others, in Geography. However, because of the course structure, we actually had many more contact hours in botany, and for my part, I felt that this was my ‘home department’.

Three years passed quickly and (mainly) happily. The odd pull at the old heart strings, falling in and out of love. I took up folk dancing, and started a Morris dancing team, The Red Stags, that continues today but outside the university as a mixed male-female side dancing Border Morris.

And so, in late May 1970 (the day after the Late Spring Bank Holiday), we sat (and passed) our final exams (Finals), left Southampton, and basically lost contact with each other.

In developing this blog, I decided to try and track down my ‘Combined’ colleagues John, Stuart, and Jane. Quite quickly I found an email address for Stuart and sent a message, introducing myself. We exchanged several emails, and he told me a little of what he had been up to during the intervening years.

Despite my best efforts, I was unable to find any contact information for John, although I did come across references to a ‘John Grainger’ who had been involved in wildlife conservation in the Middle East, primarily Saudi Arabia and Egypt. The profile seemed right. I knew that John had stayed on at Southampton to complete a PhD in ecology. Beyond that – nothing! Then, out of the blue in late 2015, John contacted me after he’d come across my blog and posts that I had written about Southampton. We’ve been in touch ever since.

To date, I’ve had no luck tracking down Jane.

Why choose Southampton?
Southampton was a small university in the late 1960s, maybe fewer than 5000 undergraduates. There was no medical faculty, and everything was centred on the Highfield campus. I recently asked John why he decided to study at Southampton. Like me, it seems it was almost by chance. We both sat the same A level exams: biology, geography, and English literature, and we both applied for quite a wide range of university courses. He got a place at Southampton through clearing; I had been offered a provisional place (Southampton had been my third or fourth choice), and my exam results were sufficiently good for the university to confirm that offer. I’d been very impressed with the university when I went for an interview in February. Instinctively, I knew that I could settle and be happy at Southampton, and early on had decided I would take up the offer if I met the grade.

John and I are very much in agreement: Southampton was the making of us. We enjoyed three years academics and social life. It gave us space to grow up, develop friendships, and relationships. As John so nicely put it: . . . thank you Southampton University – you launched me.

My story after 1970
After Southampton, I moved to the University of Birmingham in September 1970, completing a MSc in conservation and use of plant genetic resources in 1971, then a PhD under potato expert Professor Jack Hawkes in 1975. Thus began a career lasting more than 40 years, working primarily on potatoes and rice.

By January 1973 I’d moved to Peru to work in international agricultural research for development at the International Potato Center (CIP), remaining in Peru until 1975, and moving to Costa Rica between 1976 and 1981. Although it was not my training, I did some significant work on a bacterial pathogen of potatoes in Costa Rica.

I moved back to the UK in March 1981, and from April I taught at the University of Birmingham in the Dept. of Plant Biology (formerly botany) for ten years.

By 1991, I was becoming restless, and looking for new opportunities. So I upped sticks and moved with my family to the Philippines in July 1991 to join the International Rice Research Institute (IRRI), firstly as Head of the Genetic Resources Center until 2001, and thereafter until my retirement in April 2010 as Director for Program Planning and Communications.

In the Philippines, I learned to scuba dive, and made over 360 dives off the south coast of Luzon, one of the most biodiverse marine environments in the country, in Asia even.

Retirement is sweet! Back in the UK since 2010, my wife Steph and I have become avid National Trusters (and seeing much more of the UK than we had for many years); and my blog absorbs probably more time than it should. I’ve organized two major international rice congresses in Vietnam in 2010 and Thailand in 2014 and just completed a one year review of the international genebanks of eleven CGIAR centers.

I was made an OBE in the 2012 New Year’s Honours for services to international food science, and attended an investiture at Buckingham Palace in February 2012.

Steph and I met at Birmingham when she joined the genetic resources MSc course in 1971. We married in Lima in October 1973 and are the proud parents of two daughters. Hannah (b. 1978 in Costa Rica) is married to Michael, lives in St Paul, Minnesota, and works as a group director for a company designing human capital and training solutions. Philippa (b. 1982), married to Andi, lives in Newcastle upon Tyne, and is Senior Lecturer at Northumbria University. Both are PhD psychologists! We are now grandparents to four wonderful children: Callum (7) and Zoë (5) in Minnesota; and Elvis (6) and Felix (4) in Newcastle.

Stuart’s story (in his own words, 2013)
I spent my first year after Southampton teaching English in Sweden and the following year doing a Masters at Liverpool University. From there I joined Nickersons, a Lincolnshire-based plant breeding/seeds business, acquired by Shell and now part of the French Group Limagrain. 

In 1984 I returned to my native Devon to run a wholesale seeds company that fortunately, as the industry rationalised, had an interest in seed-based pet and animal feeds. Just prior to coming home to Devon I was based near York working with a micronutrient specialist. A colleague of mine there was Robin Eastwood¹ who certainly knew of you. Robin tragically was killed in a road accident while doing consultancy work in Nigeria.

This is my third year of retirement. We sold on our business which had become centred around wild bird care seven years ago now and I stayed on with the new owners for four years until it was time to go !

Stuart has a son and daughter (probably about the same as my two daughters) and three grandchildren.

John’s story
John stayed on at Southampton and in 1977 was awarded his PhD for a study that used clustering techniques to structure and analyse grey scale data from scanned aerial photographs to assess their use in large-scale vegetation survey. In 1975 he married his girlfriend from undergraduate days, Teresa. After completing his PhD, John and Teresa moved to Iran, where he took up a British Council funded lecturing post at the University of Tehran’s Higher School of Forestry and Range Management in Gorgan, on the southern shore of the Caspian Sea.

Alice, Teresa, and John at the Hejaz railway in Saudi Arabia, c. 1981/82.

By early 1979 they were caught up in the Iranian Revolution, and had to make a hurried escape from the country, landing up eventually in Saudi Arabia in February 1980, where John joined the Institute of Meteorology and Arid Land Studies at King Abdul Aziz University in Jeddah. Between Iran and Saudi Arabia there was an ‘enforced’ period of leisure in the UK, where their daughter Alice was born in December 1979.

John’s work in Jeddah included establishing an herbarium, researching traditional range conservation practices (hima system), and exploring places with intact habitats and interesting biodiversity. This is when his career-long interest in and contributions to wildlife management took hold, and in 1987 he joined a Saudi Commission for wildlife conservation. The work included an ambitious programme of establishing protected areas and breeding endangered native wildlife species for re-introduction – particularly Arabian oryx, gazelles and houbara bustards. The photos below show some of the areas John visited in Saudi Arabia, often with air logistical support from the Saudi military. 

In 1992, he was recruited by IUCN to lead a protected area development project in Ghana where he spent an exhausting but exhilarating 28 months doing management planning surveys of eight protected areas including Mole National Park. Then in 1996, the Zoological Society of London appointed him as  the project manager for a five year, €6 million EU-funded project in South Sinai to establish and develop the Saint Katherine Protectorate. John stayed until 2003, but by then, Teresa and he had separated; Alice had gained a good degree from St Andrew’s University in Scotland.

With a range of other assignments, and taking some time out between in Croatia, South Africa and other places, he was back in Egypt by 2005 to head up a project aimed at enhancing the institutional capacity of the Nature Conservation Sector for planning and implementing nature conservation activities. By 2010, and happily settled with a new partner, Suzanne, John moved to South Africa for several years, returning to Somerset in the past year. Suzanne and John were married in 2014. Retirement brings extra time for pastimes such as sculpting (many stunning pieces can be seen on his website), and some continuing consultancies in the wildlife management sector.

But I can’t conclude this brief account of John’s career without mentioning his thoughts on what being at Southampton meant to him: I have many reasons to be grateful to Southampton University – the degree involved me in the nascent environmental movement and provided me with the general tools and qualifications to participate professionally in the field. It was I think in the years that I was a postgraduate that I learned the true value of being at university and to become intellectually curious.

John sent me a more detailed account of his post-Southampton career that you can read here.

What next?
Fifty fruitful years. Time has flown by. I wonder what others from our cohort got up to? I have some limited information:

  • Allan Mackie went into brewing, and he and I used to meet up regularly in Birmingham when I was a graduate student there.
  • Peter Winfield joined what is now the Department for Agriculture & Fisheries for Scotland at East Craigs in Edinburgh.
  • Diana Caryl married barrister Geoffrey Rowland (now Sir Geoffrey) who she met at Southampton, and moved to Guernsey, where Geoff served as the Bailiff between 2005 and 2012. She has been active with the plant heritage of that island.
  • Mary Goddard completed a PhD at the Plant Breeding Institute in Cambridge (awarded by the University of Cambridge), and married Dr Don MacDonald from the university’s Dept. of Genetics.
  • Zoologist John Jackson (who took the subsidiary botany course for two years) completed a Southampton PhD on deer ecology in the New Forest, and spent many years in Argentina working as a wildlife coordinator for INTA, the national agricultural research institute.

The others? Perhaps someone will read this blog and fill in some details. As to geography, I have no contacts whatsoever.

However, through one of the earliest posts on this blog, Proud to be a botanist, which I wrote in April 2012, I was contacted by taxonomist Les Watson, who was one of the staff who took us on the first year field course to Co. Clare, and by graduate student Bob Mepham, who had taught a catch-up chemistry course to students like John Grainger and me, as we hadn’t studied that at A Level, and which was a requirement to enter the Single Honours course in botany. Another botany graduate, Brian Johnson, two years ahead of me and who sold me some books he no longer needed, also commented on one post about a field course in Norfolk.

I’m ever hopeful that others will make contact.
