The passing of one of CIMMYT’s Distinguished Scientists

HC-ElSalv-Sep09-crop2The CIMMYT community and friends across the globe mourn the loss of great maize breeder Hugo Salvador CĂłrdova Orellana who died on 25 December 2009. Hugo spent 32 years with the center striving, and often times succeeding, to increase global food security.

In Hugo’s three decades with CIMMYT he drastically changed the world of maize in Central America. He contributed to the development and spread of improved maize varieties across millions of hectares; promoted and popularized quality protein maize (QPM); co-authored hundreds of papers; and was an inspiration to his students, staff, and the global agricultural community. In recognition of a great mind, persevering work ethic, and complete dedication to his calling, Hugo earned the title of CIMMYT Distinguished Scientist, a title held by only five other center members. Despite official retirement from CIMMYT in 2007, Hugo continued his work as a CIMMYT consultant until his death.

Hugo first arrived at CIMMYT in September of 1969 as a trainee in the Global Maize Program. He then spent several years with the National Agriculture School Santa Tecla in El Salvador, his native country, before returning to El BatĂĄn in 1975 as a maize post-doctorate. His work focused on maize breeding and agronomy for Central America and he played a major role in the development of the Regional Maize Program (PRM), a network of researchers from nine countries and CIMMYT that worked with support from the Swiss Agency for Development and Cooperation (SDC) to develop and spread improved maize varieties and crop management practices. An estimate in the mid-1990s credits CĂłrdova and PRM members for adding USD $70 million annually to the value of Central American grain production.

In 1992 he joined the Tropical Lowland Maize Subprogram. An expert breeder with a tireless work ethic, Hugo helped develop over 70 inbred maize lines, which have been released in over 15 countries. It is estimated that at least 4 million hectares throughout the developing world are sown with maize varieties that at some point passed through Hugo’s hands.

Hugo became the coordinator of the Global Quality Protein Maize (QPM) Program in 1997. He helped develop several high-yielding QPM varieties and it is largely thanks to his efforts that 0.5 million hectares in Central American are sown with QPM, a type of enhanced maize that increases consumers’ protein intake and can help decrease malnutrition.

The passion Hugo had for his work was evident to all who knew him and was further highlighted by over 50 recognitions and awards. Many the awards were bestowed by Latin American governments who saw first-hand the benefits Hugo’s work had in their respective countries. Hugo leaves behind a wealth of knowledge: he co-authored hundreds of publications, mentored more than 60 graduate and undergraduate students, and coordinated or lectured in numerous training courses.

Condolences are offered to Hugo’s wife, AmĂ©rica, and his children, Lucy and Hugo. Though Hugo is no longer with us, the seeds he planted, both in the ground and in our memories, will grow on.

Innovative partnerships boost livestock-maize systems in eastern Africa

In recent times, in eastern Africa, arable land has become more scarce and livestock production has gained more ground, making maize more important than ever—both as a source of food and feed—in highly intensified crop-livestock farming systems. In an innovative partnership, CIMMYT, the International Livestock Research Institute (ILRI) and partners from universities, research centers, and ministries of agriculture in Ethiopia, Tanzania , Kenya, and Germany have worked together to develop and evaluate dual-purpose maize cultivars to meet the increasing need for livestock fodder in a project funded by BMZ from 2005 to 2009. The partnership—new to all those involved—brought together socio-economists, animal scientists, maize breeders, and spatial analysts.

Recently, CIMMYT and ILRI organized an end-of-project workshop themed “Improving the Value of Maize Stover as Livestock Feed” in Addis Ababa, Ethiopia for stakeholders to review results of the project and agree on future directions. Maize stover is the leftover leaves, stalks, husks, and cobs after a harvest.

“Livestock is important in Ethiopia—contributing 40% to our gross domestic product (GDP). Available grazing land has decreased while the area under maize has increased. Therefore, stovers have become an important source of fodder,” said Adefris Teklewold, crop research process director at the Ethiopian Institute of Agricultural Research (EIAR), who opened the workshop. “However, maize stover has low nutritive value and this project has the potential of increasing its value as livestock feed.”

Researchers found that that farmers value grain yield much more than stover fodder value, and would adopt an improved variety only if it gave reasonable yields. Nevertheless, farmers do recognize differences among varieties in the fodder value of stover, particularly in traits such as ‘stay-green,’ softness of stalks, and palatability. After grain yield and food related attributes, stover biomass is an important characteristic upon which farmers base their selection of varieties.

The project successfully explored the potential to improve maize stover for livestock fodder and identified traits that could be used by breeding programs to do so. These traits would serve as additional ‘value added’ release criteria rather than requirements for release to facilitate optimization of whole plant utilization. To adopt and implement these findings will require more widespread awareness among actors in the food-feed value chain, including government extension workers, private seed companies, and farmers so that breeding for improved stover quality can be integrated in national maize breeding programs. Workshop participants also recognized competition for other uses of stover, such as fuel and fencing, as well as its importance in soil conservation. As Teklewold advised, “Reducing soil degradation and erosion from the hillsides and sloping fields on which much of Ethiopian agriculture is practiced is an urgent need. Reduced tillage and residue conservation are crucial to this task.” Participants were left with the challenge of how to reconcile the competing demands for crop residues in maize-livestock systems.

Socioeconomics Program (SEP) Strategy Meeting

The newly established Socioeconomics Program (SEP) held a strategy development meeting in Addis Ababa 14-17 December 2009. The social scientists of CIMMYT from the different regions convened for the first full meeting since 2005 to discuss the future directions of the program. The purpose of the meeting was to brainstorm on Program revitalization. This included taking stock of achievements, reviewing existing and emerging challenges, and identifying new opportunities for growth and development of the research program. This provided the foundation for rethinking and determining strategic directions, within the goal and mission of CIMMYT, to identify and define research thrusts. Specific objectives of the meeting included:

  • Assessing the global and regional challenges for maize and wheat systems and identifying key research issues.
  • Defining priority research themes by region and identify goals, outputs and outcomes.
  • Identify potential research projects under each of the strategic priority themes and develop the log-frame.
  • Beginning to develop a strategy document, later to be reviewed internally and externally.

The meeting also identified major selling points or flagships of the SEP. The strategy will be reviewed both internally within CIMMYT and externally by donors and other stakeholders. Participants were Pedro Aquino; Hugo De Groote; Olaf Erenstein; V?esh Krishna, Roberto La Rovere, Mulugett a Mekuria, Girma Tesfahun, Jon Hellin, Bekele Shiferaw, and Kai Sonder.

Seed Warriors – film

CIMMYT’s deputy director general for reserarch and partnerships, Marianne Bašnziger, will be featured in the new documentary film Seed Warriors: http://seedwarriors.org

In the remote Norwegian town of Longyearbyen, just 1000 kilometres from the North Pole, politicians from around the world came to celebrate the opening of the world’s first global seed bank. After years of difficult negotiations and searching for the right spot, this was deemed to be the safest place on earth. Eventually, 4.5 million seed samples will be stored in this »Doomsday Vault« and ensure the continued existence of biodiversity.

But is the dream of global food security achievable? By 2050 temperatures worldwide are expected to rise by at least 2 degrees. This will result in a 30 per cent drop in production of food crops. By this time global food demand will have doubled. How will we feed the world?

In SEED WARRIORS we hear from the scientists behind this ambitious project and examine the reality of the fight against hunger.

In Kenya, where drought is a recurring problem, we meet Zachary Muthamia, the director of the National Seed Bank, who is using the limited resources available to him to preserve his country’s existing biodiversity and send copies of Kenya’s unique plant heritage to Norway before his energy eating generators die for good. And we meet Marianne Ba¹nziger, one of the world’s leading experts on maize. She’s using the same biodiversity to develop non-genetically modified seeds that yield 20 to 30 percent more than existing seeds and thrive in conditions of drought.
But time is running out.

New Chair of CGIAR Consortium

Chair-CperezAt its Annual Business Meeting in Washington, DC, on 07-08 December 2009, the Consultative Group on International Agricultural Research (CGIAR) announced the selection of Uruguayan Carlos PĂ©rez del Castillo as Chair of the new Consortium of CGIAR centers. PĂ©rez del Castillo has served as special advisor on International Trade Negotiations to the President of Uruguay and permanent representative of Uruguay to the United Nations. He has also worked for the World Trade Organization (WTO) and carried out various consultancy and advising assignments with the Inter-American Development Bank, the Inter-American Institute for Cooperation on Agriculture, the United Nations Conference on Trade and Development (UNCTAD), and the Latin American Association for Integration (ALADI). In 1990 he was awarded “The Dr. Raul Prebisch Award in Economics” by the Association of Latin American and Caribbean Economists, and he is a permanent member of the Harvard University Trade Group. CIMMYT Board Chair Julio BerdeguĂ© chaired the Search and Selection Committ ee for the appointment.

Teosinte monitoring trip

diploperennisAA CIMMYT team donned their expedition gear in November 2009 and set off to collect samples of teosinte, a wild relative of maize that is disappearing. The team obtained a special permit from the Mexican Department of Environment and Natural Resources (SEMARNAT) to monitor and gather annual teosinte samples from known locations in the Balsa river regions of Guerrero and MichoacĂĄn and the central plateau regions of Jalisco and Guanajuato.

The 12-person team divided into three groups and visited nearly 50 sites total. Victor Chavez and Marcial Rivas of the maize germplasm bank each led a team of five; Suketoshi Taba, head of the maize germplasm bank, and David Ellis of the United States Department of Agriculture (USDA), National Center for Genetic Resources Preservation (NCGRP) made up the third group. The groups primarily explored areas had been identified by Jesus Sanchez of the University of Guadalajara as teosinte sites. In addition, members asked local farmers for assistance locating the plants, resulting in the discovery of several new annual teosinte locations.

During their exploration, scientists stumbled upon what they believe to be the perennial teosinte Zea diploperennis near Uruapan, MichoacĂĄn. Samples were taken for further analysis. As of now, the only known natural population of this plant is in the Sierra de ManantlĂĄn Biosphere Reserve, in the state of Jalisco, Mexico.

New CIMMYT publication explores maize molecular diversity

A team of 18 scientists coordinated by CIMMYT recently published a paper that explores genetic diversity among 770 inbred maize lines. “Molecular characterization of global maize breeding germplasm based on genome-wide single nucleotide polymorphism (SNP)” was published in the December print issue of Theoretical Applied Genetics.

“This paper is a clear example of strong international cooperation and it shows the importance of the well established network led by CIMMYT,” said Sidney Parentoni, co-author and maize breeder from Embrapa Maize and Sorghum, Brazil.

The collaborating scientists from five countries used 1,034 SNP markers to discover general molecular similarities and differences among select maize lines. This is done by looking at areas on DNA that are known to vary among members of the same species; for a SNP this refers to the difference of a single nucleotide. The work resulted in millions of new data point across the 770 maize lines.

“The published research provides significant new information for maize genetic improvement including germplasm classification, heterotic grouping, and genetic differences between tropical and temperate, yellow and white, and fl int and dent maize germplasm,” said Yunbi Xu, project leader and CIMMYT maize molecular breeder, adding that the use of so many lines and markers makes the 23-page publication the largest study of its kind. Another major CIMMYT contributor was Yanli Lu, the paper’s first author (pictured above). Lu is a CIMMYT consultant who will receive her Ph.D. from Sichuan Agricultural University of China next year.

The paper and research were made possible by the use of SNP markers previously identified by non-CIMMYT related authors. This work, along with recent publications in the magazine Science documenting an improved sequence of the maize genome and the first haplotype map of maize, is an essential asset to help maize breeders use diverse germplasm and begin to implement genome-wide selection.

“The availability of genotypic information and the rapidly falling cost of genotyping are paving the way for genome-wide molecular breeding for maize at CIMMYT,” said Gary Atlin, associate director of the Global Maize Program.

Two additional papers that further examine the selected inbred maize lines are currently in the works: one on association mapping and the other on linkage mapping.

Student visit

CA-studentsNearly 20 Mexican students from the Instituto Tecnológico Superior de San Miguel el Grande in Oaxaca visited CIMMYT El Batán on 01 December 2009. Hosted by the Global Conservation Agriculture (CA) Program, the students spent half a day at the center learning about CA practices, CIMMYT, and Norman Borlaug. The day included a tour of the germplasm bank and experimental fields. “Several of the students were from marginalized communities, and with training, they have the capacity to be CA promoters and technicians in these vital areas,” said Andrea Chocobar, a member of CIMMYT CA team. Also assisting in the event were Víctor Chávez Tovar, Caritina Durán, Ricardo Romero, and Humberto González.

Chinese visitors seek partnerships in conservation agriculture

ObregonA delegation of eight scientists from the Chinese Academy of Agricultural Sciences (CAAS) and China Agricultural University (CAU), Beijing, arrived in Mexico on 28 November and traveled the following day to Ciudad Obregón. They spent three days touring the Yaqui Valley to learn about activities in CIMMYT’s northern Mexico conservation agriculture (CA) hub. On 01 December, they returned to El Batán to familiarize themselves with CA activities there, until their departure for China on 03 December. Their visit is associated with efforts to develop new collaborative activities between CIMMYT and relevant Chinese institutions to generate and promote locally-adapted CA cropping practices for major Chinese maize and wheat production systems.

Bent Skovmand: the viking in the wheat field

BentSkovOn 02 December 2009, a reception was held in New York City for a recently published book based on the life of the late Bent Skovmand, former head of CIMMYT wheat genetic resources. The Viking in the Wheat Field, written by Susan Dworkin, tells a hidden but heroic story of scientists—many associated with CIMMYT—for whom increasing the world’s food supply has been nothing less than a life’s calling. It is a story of passion, commitment, and scientific discovery. The reception was attended by about 50 people, including Bent’s wife Eugenia and daughter Astrid, Tom Payne, head of genetic wheat resources at CIMMYT, and friends of CIMMYT Cal Qualset and Bob Goodman.

Indian dignitaries and guests celebrate the life and work of Norman E. Borlaug

NB-1aDuring 21-22 November, the Indian Council of Agricultural Research (ICAR) hosted a major tribute ceremony for Norman E. Borlaug at its NASC complex in New Delhi. Some 200 participants attended the inaugural session, which featured a welcome and memorial address by Mangala Rai, secretary, Department of Agricultural Research and Education (DARE), ICAR director general and former CIMMYT Trustee. There were memorial addresses by T Nanda Kumar, secretary, Department of Agriculture and Cooperation (DAC); Mahmoud Solh, director general, ICARDA; M.S. Swaminathan, chairman, MSSRF; and K.V. Thomas, honorable minister of state (Agriculture).

Thomas Lumpkin’s presentation, entitled “India’s ‘Annadaata’ — Father of the Green Revolution,” was very well-received, according to global wheat program director Hans Braun. Braun, along with CIMMYT distinguished scientist Ravi Singh and Raj Gupta, South Asia coordinator, delivery and adaptation of cereal technology, took part in the tribute and the 1.5-day technical sessions on increasing wheat yields, controlling wheat rust diseases, promoting conservation agriculture, managing climate change and abiotic stresses, and wheat quality improvement. A valedictory function was attended as well by Sharad Pawar, minister of agriculture, Consumer Affairs, Food & Public Distribution.

CA training in India

AC-india1Nearly 20 delegates from North Bengal Agriculture University’s agricultural outreach stations and several local farmers attended a conservation agriculture (conservation agriculture) traveling training seminar in India during 29-30 October 2009.

At a field owned by farmer Paras Nath and located in Paghra village of the Samastipur District, presenters explained laser-land leveling, zero-tillage, and bed planting. The first presenter, Sanjeev Kumar, service engineer from the laser manufacturing company Leica, Elcom Technologies Pvt Limited, in Gurgaon, India, described the use of the laser system and provided hands-on training for laser-land leveling, a practice that improves productivity and conserves irrigation water. Next, CIMMYT agronomist Raj Kumar demonstrated zero-till planting for lentils and bed planting for maize.

AC-India2Participants then traveled to Rajendra Agriculture University’s (RAU), Pusa Farm, where they saw CA-based longterm experimental trials of rice-wheat and rice-maize systems. Following this, the delegation visited participatory trials of zero-till rice and listened to additional CA information and herbicide application techniques presented by CSISA hub manager Ravi Gopal. Finally, S. Chowdhury, CIMMYT seed production specialist, spoke about new wheat varieties suitable for the eastern Indo- Gangetic Plains.

Nutritious and delicious

India1-300x215Tortillas made from quality protein maize (QPM) are now being sold on the streets in Patna, the capital city of Bihar, India. CIMMYT-India donated a QPM tortilla unit to Magadh Credit Cooperative Society (MCCS) and the society is now selling five tortillas with curry for about US$ 0.25 (10-12 rupees). The program is based on a “meals on wheels” scheme and the food will be sold at mobile shops and Sudha milk booths across Patna. The goal is to provide affordable, healthy food to the city’s urban poor. CIMMYT and Cereal System Initiative for South Asia (CSISA) are working to strengthen inbred production of hybrid QPM seed in eastern India to support this production chain.

Symposium at CIMMYT for wheat yield consortium

SimposiumWheatNearly 60 world-renowned scientists and wheat experts gathered at El Batán during 10-13 November 2009 for the intensive workshop “Complementary strategies to raise wheat yield potential.” The event was divided into four main topics: imperatives for raising wheat yield potential; improving crop photosynthesis; optimizing adaption, yield, and lodging resistance; and combining complementary traits through breeding. The ultimate aim is to get new, high-yielding wheat varieties to farmers as quickly as possible.

“This consortium is hugely valuable because we bring together expertise from very different areas and direct it toward one goal: improving wheat yield potential,” says Xinguang Zhu, and workshop participant and principal investigator from the Chinese Academy of Sciences. “By working on things together, we greatly improve our chance of realizing this goal.”

The week was also an opportunity to further establish a consortium that will continue collaboration to improve wheat yields, says Matthew Reynolds, wheat physiologist and initiator of the consortium. A fullyfunctional consortium will require an estimated USD 25-30 million for five years.

Maize as a cash intercrop with perennials in Colombia

For about six years, CIMMYT and the large Colombian producer federations for coffee (FEDERECAFE) and cereals (FENALCE) have partnered to help coffee growers profit by cropping maize in the rows between pruned coffee plants, obtaining as many as three maize harvests while the coffee plants grow back. Led by maize breeder Luis Narro, CIMMYT has contributed hybrids that yield as much as 10 tons per hectare and are resistant to locally-important fungal diseases, particularly those caused by Cercospora zeae-maydis and Phyllachora maydis. As one result, over the short life of this work maize area in coffee zones has already gone from 5,000 to 60,000 hectares, with a potential area of 150,000 hectares.

This success has also bred a new partnership involving CIMMYT, FENALCE, and the Federation of Oil Palm Growers (FEDEPALMA), in which palm plantations will obtain three to four maize harvests while palm plants complete their growth cycle. Oil palms are grown on 350,000 hectares in Colombia, though the potential is 10 times that area. The palm-maize intercrop seems especially attractive given that many Colombian plantations are completely renewing their oil palm stands, due to severe attacks of bud rot disease (Phytophthora palmivora). This disease and other constraints are severely affecting smallscale (less than five hectares) palm growers in locations like Tumaco, who were previously earning at least USD 1,500 per month selling palm for oil extraction. Critically, farmers’ production losses also represent lost employment for farm hands, who are typically economically-disadvantaged. Growing maize offers a profitable hedge for all, while producers wait for the new generation of palm plants to come on line.

To date, 500 experimental maize hybrids have been tested in trials in 4 oil palm plantation zones. According to 90 farmers who took part in a field day in Tumaco on 30 October 2009, the trial results have been good. The highest yields surpassed 10 tons per hectare, with yields of 7 tons and profits of USD 1,500 per hectare on small-scale farmers’ plots.

“Maize could be of interest for farmers who might otherwise be tempted to grow drug crops, ” says Narro. “Maize also offers a profitable alternative for farmers in marginal zones who grow coconut palms in countries threatened with total crop loss from the lethal yellowing diseases.”
