Thomas Payne, head of the Wheat Germplasm Bank at the International Maize and Wheat Improvement Center (CIMMYT), was awarded the Frank N. Meyer Medal for Plant Genetic Resources this morning at the annual meeting of the American Society of Agronomy, the Crop Science Society of America, and the Soil Science Society of America, held in San Antonio, Texas.

The Frank N. Meyer Medal recognizes contributions to plant germplasm collection and use, as well as dedication and service to humanity through the collection, evaluation or conservation of earth’s genetic resources. The award was presented by Clare Clarice Coyne, U.S. Department of Agriculture (USDA) research geneticist.

As an award recipient, Payne delivered a lecture that touched on the philosophy, history and culture surrounding plant genetic diversity and its collectors, and CIMMYT’s important role in conserving and sharing crop diversity.

The scientist has focused his career on wheat improvement and conservation. In addition to leading CIMMYT’s Wellhausen-Anderson Wheat Genetic Resources Collection, one of the world’s largest collection of wheat and maize germplasm, he manages the CIMMYT International Wheat Improvement Network. He is the current Chair of the Article 15 Group of CGIAR Genebank Managers, and has served as Secretary to the CIMMYT Board of Trustees. His association with CIMMYT began immediately after obtaining a PhD at the University of Nebraska–Lincoln in 1988, and he has held positions for CIMMYT in Ethiopia, Mexico, Syria, Turkey and Zimbabwe.

“CIMMYT is the largest distributor of maize and wheat germplasm worldwide, with materials emanating from its research and breeding programs, as well as held in-trust in the germplasm bank. The Meyer Medal is a reflection of the impact CIMMYT makes in the international research community — and in farmers’ fields throughout the developing world,” Payne said.

Located at CIMMYT headquarters outside Mexico City, the CIMMYT Wheat Germplasm Bank contains nearly 150,000 collections of seed of wheat and related species from more than 100 countries. Collections preserve the diversity of unique native varieties and wild relatives of wheat and are held under long-term storage for the benefit of humanity, in accordance with the 2007 International Treaty on Plant Genetic Resources for Food and Agriculture. The collections are also studied and used as a source of diversity to breed for crucial traits such as heat and drought tolerance, resistance to crop diseases and pests, grain yield productivity, and grain quality. Seed is freely shared on request to researchers, students, and academic and development institutions worldwide.

In his remarks, Payne also highlighted the story of Frank N. Meyer, after whom the award is named. Meyer, an agricultural explorer for the USDA in the 1900s, spent a decade traveling under harsh conditions through China to collect new plant species suitable for production on the United States’s expanding farmland. Among more than 2,500 plants that he introduced to the U.S. — including varieties of soybeans, oats, wild pears, and asparagus — the Meyer lemon was named in his honor. As he pointed out, Meyer worked during a historical period of great scientific discoveries, including those by his contemporaries Marie Curie and the Wright brothers.

Among those attending the ceremony were Payne’s sister, Susan Payne, and CIMMYT colleagues Kevin Pixley, director of Genetic Resources; Denise Costich, head of the CIMMYT Maize Germplasm Bank; and Alexey Morgunov, head of the Turkey-based International Winter Wheat Improvement Program.

The head of CIMMYT’s Global Wheat Program Hans-Joachim Braun and CIMMYT scientist Alexey Morgunov are also receiving honors or awards this week at the annual meeting of the American Society of Agronomy, the Crop Science Society of America, and the Soil Science Society of America. The meeting convenes around 4,000 scientists, professionals, educators, and students to share knowledge and recognition of achievements in the field.

EL BATAN, Mexico (CIMMYT) — The “Doomsday Vault,” that safeguards fall-back collections of key food crop seeds in the arctic cold of Longyearbyen, Norway, marks its tenth anniversary this year. To celebrate, leaders in the conservation of crop genetic resources are gathering next week to discuss best practices and to encourage sustainable use of the resources.

The Svalbard Global Seed Vault sits 1,300 kilometers north of the Arctic Circle; the farthest north commercial flights will take you. It is described as the world’s largest secure seed storage and was established by the Norwegian Government in February 2008. Repurposing an abandoned coal mine, the global seed vault is set deep into the natural permafrost of the Norwegian island of Svalbard.

Over the last decade, seed-preserving institutions worldwide have shipped backup collections of seed and other plant parts for storage in the vault, which now holds nearly 900,000 varieties of essential crops, representing over 4,000 plant species, which could be drawn upon to restart agriculture in case of a catastrophe.

The International Maize and Wheat Improvement Center (CIMMYT) is the top contributor to the vault, with over 150,000 unique collections containing a total of nearly 50 million seeds and representing roughly 85 percent of the entire CIMMYT germplasm bank collection.

The target is to have 90 percent of the CIMMYT entire collection backed up at Svalbard within two years, according to Thomas Payne, head of CIMMYT’s Wheat Germplasm Bank, which is located in Mexico. CIMMYT’s Maize Germplasm Bank, led by Denise Costich, has already reached that goal.

“We send seeds every other year, accumulating packets until we have a critical mass and sending them in a large, single shipment,” Payne said.

Preparing and shipping the seed involves intricate coordination and painstaking work. For starters, seed must be sent in the winter to avoid it sitting on hot airport tarmacs. Additionally, the Svalbard vault opens for new deposits only a few times a year, so shipping logistics need to match up those dates.

Only seed of the highest quality is sent to Svalbard, in part to ensure that the stored seed retains as long as possible its ability to germinate.

CIMMYT Germplasm Bank seed collections are regularly tested for germination capacity by placing a batch of seeds in a wet paper towel for 7-10 days. When less than 85 percent of a unique collection is viable, then the entire collection is replaced with fresh seed grown from the viable portion.

“There are seed collections at CIMMYT that still meet the minimum viability standard after more than 50 years under storage,” Payne said, noting that the center’s long-term collections are kept at minus 18 degrees Centigrade and in low humidity.

Payne said the center keeps duplicate collections in Mexico of all the seed it sends to Svalbard and monitors those Mexico back-ups to keep tabs on the viability of its Svalbard deposits.

Payne explained “To check seed viability, we have to take seeds out of storage, representing a loss of several hundred seeds. It’s almost a self-defeating process, balancing viability testing with sufficient quantities of seed to test and distribute.”

Payne said scientists are seeking new, non-invasive ways to test seed viability, potentially by checking seed respiration rates or rapid germination imaging technologies.

The government of Norway and the Global Crop Diversity Trust cover the cost of storage and upkeep of the Svalbard Global Seed Vault, coordinating shipments in conjunction with the Nordic Genetic Resource Center.  Established in 2006, the Crop Trust supports the conservation and availability of crop diversity for food security worldwide and helps to fund CIMMYT’s work to collect and conserve maize and wheat genetic resources.  The CGIAR Genebank Platform also supports CIMMYT’s maize and wheat germplasm bank.
