Honoring the memory of former maize director, Rip Paliwal

We are sad to inform readers that on 05 January 2013, at the age of 84, Ripusudan L. Paliwal, a CIMMYT employee for 17 years who served as director of the maize program, passed away in the presence of his family near New Delhi, India. Rip, as he was respectfully and affectionately known by colleagues, came to CIMMYT as associate director of the maize program in 1976, after serving as dean of the college of agriculture of GP Pant University, Pantnagar, India. Former colleague and retired CIMMYT maize director Ron Cantrell called Paliwal a major factor in the success of the maize program. “I have nothing but fond memories of my time at CIMMYT and one of the principal reasons was the support and friendship of Rip,” says Cantrell. “He was an invaluable source of information about tropical maize and the national programs throughout the world.” His activities after retirement from CIMMYT in 1993 included authoring books such as the 2000 FAO publication “Tropical maize: Improvement and production.” The CIMMYT family extends its sincere sympathy and prayers to the Paliwal family, including children Nirupama, Nivedita, Muktesh, and Sarvesh, who worked as a CIMMYT maize scientist in the early 2000s.

CIMMYT mourns the passing of Twumasi-Afriyie, creator of the quality protein maize Obatanpa

Dr-TwumasiOn 03 January 2013, 63-year-old Ghanaian-born maize breeder Strafford Twumasi-Afriyie succumbed to cancer, leaving a substantive legacy that includes the creation of the world’s most widely-sown quality protein maize (QPM) variety, Obatanpa. His demise represents a huge loss to family, friends, hundreds of colleagues and collaborators, and many thousands of farmers. A highly-committed and knowledgeable scientist, Twumasi is remembered by all for his kind, gentle demeanor and modesty, as well as for building strong partnerships.

Twumasi worked at the Crops Research Institute (CRI), Ghana, through much of his career. Following the completion of his MSc at the University of Guelph, Canada, in 1981, he returned to Ghana to serve with former CIMMYT maize physiologist Greg Edmeades as Joint Coordinator of the Ghana Grains Development Project funded by the Canadian International Development Agency (CIDA). It was during this period and under the aegis of the GGDP that he used CIMMYT germplasm during the early 1990s to develop Obatanpa, which by 2005 was sown on more than half of Ghana’s maize area. With support from Sasakawa-Global 2000, the International Institute of Tropical Agriculture (IITA), and CIDA, Obatanpa has been released in numerous countries of Africa, including Uganda where as “Nalongo” it is among the most popular maize varieties.

Twumasi joined CIMMYT in 1997 to develop maize varieties for African highland areas in a project supported initially by the Federal Ministry for Economic Cooperation and Development, Germany and later the Ethiopian Institute of Agricultural Research (EIAR), CIMMYT, the Association for Strengthening Agricultural Research in Eastern and Central Africa (ASARECA), and CIDA. Releases from that effort are still gaining popularity in high-altitude zones of Ethiopia.

As a breeder in CIDAfunded research in Ethiopia beginning in 2003, Twumasi worked with EIAR to develop a QPM version of the hybrid BH660, which accounts for some 60% of seed sales in Ethiopia. These and other superior varieties developed are being promoted through the new “Nutritious Maize for Ethiopia” project that Twumasi was leading. “The National Maize Program recognizes the relentless work of Dr. Twumasi for small-scale farmers of Ethiopia in particular and Africa in general,” says Berhanu Tadesse, Ethiopia’s National Maize Research Coordinator.

Edmeades remembers Twumasi as scrupulously honest, slow to judgment but always fair, and one of nature’s true gentlemen. “He was not afraid to take risks as a scientist and promote QPM when many others declared it a lost cause,” says Edmeades. “As my counterpart in Ghana I very much enjoyed working with him and came to appreciate his wry sense of humor and his lovely smile.”

Twumasi’s mentorship and tutelage helped several maize researchers from the region develop as strong breeders in their own right. His academic background included a BSc in agriculture from the University of Ghana (1975) and a PhD in plant breeding from the University of Missouri, USA (1989).

The CIMMYT family extends its sympathies to Twumasi’s beloved wife, Veronica, his daughters Mame and Truelove, and his son Kwaku in this difficult time.

Tropicalized maize haploid inducers for doubled haploid-based breeding

tropicalized-maize-haploidThe doubled haploid (DH) technology enables rapid development of completely homozygous maize lines and offers significant opportunities for fast-track development and release of elite cultivars. Besides simplified logistics and reduced costs, use of DH lines in conjunction with molecular markers significantly improves genetic gains and breeding efficiency. DH lines also are valuable tools in marker-trait association studies, molecular marker-assisted or genomic selection-based breeding, and functional genomics.

Generating DH lines involves four major steps: (1) In vivohaploid induction; (2) haploid seed identification using morphological markers; (3) chromosome doubling of putative haploids; and (4) generating D1 (DH) seed from D0 seedlings. In vivo haploid induction is achieved by crossing a specially developed maize genetic stock called an “inducer” (as male) with a source population (as female) from which homozygous DH lines are developed.

What are tropicalized haploid inducers?
Adoption of DH technology by public maize breeding programs and small- and mediumscale enterprise (SME) seed companies, especially in developing countries, is limited by the lack of inducers adapted to the tropical/subtropical conditions. The CIMMYT Global Maize Program, in collaboration with the Institute of Plant Breeding, Seed Science and Population Genetics of the University of Hohenheim (UHo) now has tropical haploid inducers for sharing with the interested institutions under the terms outlined below.

The tropically adapted inducer lines (TAILs) developed by CIMMYT and UHo showed high haploid induction capacity (~8-10%) and better agronomic performance than temperate inducers, in trials at two CIMMYT experiment stations in Mexico. A haploid inducer hybrid developed using these TAILs revealed heterosis for plant vigor and pollen production under tropical conditions, while maintaining similar haploid induction rates (~8-10%). CIMMYT and UHo decided to share the seed and grant authorization for use of one of the tropicalized haploid inducer lines (one of the parents of a hybrid inducer) and the hybrid inducer to interested applicants, after signing of the relevant material transfer agreement (MTA) and with restrictions to protect the intellectual property rights of both institutions for the inducer lines.

Process of indenting for the tropicalized haploid inducers
Interested applicants should send a letter of intent or an expression of interest in the tropicalized haploid inducers. CIMMYT may seek more information, if required, and will share the relevant MTA template for signing by applicants. The general guidelines to obtain inducers for research use and commercial use are as follows.

For research use by publicly-funded national agricultural research systems
Publicly-funded institutions interested in access to the haploid inducers for specific purposes (e.g., to develop DH lines for breeding programs) may send a letter of intent or expression of interest to CIMMYT. For eligible institutions, the haploid inducers will be provided free-of-charge by CIMMYT and UHo, after signing of a Research Use MTA. Commercial use of the inducers by institutions or others should be in accordance with a separate license agreement for commercial use (as given below).

For commercial use
Applicants may access the inducers for commercial use pursuant to signing of a Material Transfer and License Agreement with CIMMYT and UHo. Applicants shall pay UHo a one-time licence fee of USD 25,000 for provision of seed of two haploid inducers; these include one of the parents of a tropicalized haploid inducer hybrid and the haploid inducer hybrid itself. If applicants wish to access the other parent of the haploid inducer hybrid, an additional one-time licence fee of $10,000 will be payable to UHo.

Mainstreaming gender in maize improvement research

DSC02358“Women are a key part of the mainstream in agriculture, yet they face formidable obstacles,” said CIMMYT gender and development specialist Vongai Kandiwa during a recent seminar in Nairobi, Kenya. Vongai was speaking on the importance of having a strategy to put men and women’s concerns and experiences at the centre of research design, implementation, monitoring, and evaluation. This involves looking at the socioeconomic settings of men and women to ensure that they benefit equally – often referred to as “gender mainstreaming.” The seminar was attended by colleagues working on various aspects of maize technology development, production, and dissemination. “By closing the gap in access to technology between men and women, we could increase productivity by 30%,” said Vongai, referring to the State of Food and Agriculture report (2010-2011) by the Food and Agriculture Organization of the UN (FAO). According to Vongai, this would contribute to child survival and nutrition, as “women are key to household food security.”

Vongai emphasized the importance of considering gender in our work. She explained that gender shapes patterns of power relations, asset and wealth distribution and control, labor allocations, as well as preferences and aspirations within households. Mainstreaming gender is encouraged by most donors, she said, citing an example from the Bill & Melinda Gates Foundation which encourages moving from neutrality to awareness and finally to gender transformative program design and implementation.

Many organizations may be considered gender “aware”— that is, they are able to generate gender disaggregated data on the stakeholders that benefit from their development work — but transformation lies in using that information to improve the products and services delivered, paying specific attention to women’s preferences. “The woman is the custodian of food in most African societies,” said Vongai. As the ultimate consumers of our maize products, women ought to be involved in the research for development activities. “We have to make it convenient for women to attend activities and pay attention to the composition of groups we convene,” said Vongai. “This could be done by working with women’s groups and using female technicians,” she said. By making a deliberate effort to accommodate women’s needs and voices in the selection of maize varieties, we make it possible to meet their needs.

DSC023331Paying particular attention to research innovations that would reduce the drudgery of farm work for women is also important, highlighted the global maize program director B.M. Prasanna. Prasanna pointed to quality protein maize (QPM) as a product developed with the nutrition needs of end users—and particularly women— in mind. QPM has increased amounts of lysine and tryptophan, important amino acids which improve nutrition. Prasanna also pointed out the promise of pesticide resistant maize that would reduce the burden of weeding for women who often provide most of the farm labor.

“When we take the stance that gender matters, we can start to satisfy the needs of our clients, both male and female,” argued Vongai picturing the scenario when gender considerations will be made in all aspects of our work; breeding, seed systems, impact assessment, and communication.

Congratulations to Germplasm Bank!

The CIMMYT Maize and Wheat Germplasm Bank achieved ISO9001:2008 certification this week, after nearly two years of data gathering, intensive analysis, and assessment of processes and best practices. The ISO standards relate to quality management systems and are designed to help organizations ensure that they meet the needs of customers and other stakeholders, while meeting statutory and regulatory requirements. The CIMMYT Maize and Wheat Germplasm Bank is the first CGIAR germplasm bank to achieve ISO9001 certification, and is now one of only three genebanks globally to achieve certification (and the first outside of Europe). CIMMYT staff and areas involved in this certification included both the germplasm banks, human resources, purchasing, risk management, security, maintenance, and ICT departments. A special thanks is extended to Bibiana Espinosa and Paulina Gonzalez, both of whom sheparded the lengthy process to this noteworthy conclusion.

Improving wheat seed system and end-use quality in Ethiopia

“My work in Africa is not finished,” Jeanie Borlaug quoted her father, Dr Norman Borlaug, during her opening statement for wheat seed system field day bringing together farmers, researchers, seed growers, and development enterprises experts to discuss improved seed system and end-use quality issues in Ethiopia. The field day was held at the Kulumsa Research Center (KRC), Ethiopia, on 15 November 2012 and was followed by an end-use quality workshop on 16 November. Both events were organized by KRC and CIMMYT and sponsored by Cornell University’s Durable Rust Resistance in Wheat Project (DRRW).

Calls to adopt SIMLESA approach in project implementation across Tanzania

“The Ministry, and specifically the Directorate of Research and Development, immensely commends SIMLESA’s participatory approach and would like to recommend it to other research and development partners both at national and international levels. By any means, this approach won’t ignore or omit farmer participation in variety dissemination, as was the case in the past. This participation exactly addresses the value chain approach that has been over emphasized by the Agricultural Sector Development Program that we are implementing in our country,” stated Fidelis Myaka (director of Research and Development, Ministry of Agriculture, Food Security and Cooperatives, Tanzania) in a speech read on his behalf by Ruth B. Madulu, Agricultural Research Institute (ARI)-Mikocheni at the recently concluded Tanzania SIMLESA 2012 Progress Review and 2013 Planning Meeting in Arusha.

Improving postharvest grain storage and loss assessment methods

In November, twelve researchers and development practitioners implementing phase two of the Effective Grain Storage for Sustainable Livelihoods of African Farmers Project (EGSP II) travelled from Malawi, Zambia, Zimbabwe, and Kenya, for training on improved postharvest grain storage and loss assessment methods in Nairobi, Kenya.

The course was facilitated by Prof. Rick Hodges, University of Greenwich, UK, and CIMMYT Socioeconomist Hugo De Groote, Policy Economist Jones Govereh, and Project Leader Tadele Tefera. Practical and theory sessions covered topics such as hermetic storage, postharvest technologies, estimating storage losses, assessing ear and grain damage, economic data requirements and collection, and economic analysis of on-station and on-farm storage trials.

Participants were also introduced to the Africa Postharvest Loss Information Service (APHLIS); a system with an innovative framework for analyzing and computing quantitative postharvest losses under different farming and environmental conditions in eastern and southern Africa. It was discussed how using the APHLIS downloadable calculator can support loss reduction projects. According to Hodges, the advantages of this system are that its measure of percentage weight loss of grain is based on an actual reduction in the dry weight of grain; it does not account for changes in quality unless the grain is no longer fit for human consumption; and losses are cumulatively calculated from production and including each step in the postharvest chain.

Despite the importance of economically analyzing crop and storage pest losses, Govereh lamented that such analyses are not well established in the research community. “Economic analysis is rarely available, especially for on-farm losses. In most cases, crop losses are commonly overestimated with benefits often overstated and costs underestimated.”

Govereh outlined the economic analysis of crop and storage pests: estimating the extent of the problem (the area infested); estimating the intensity of the problem (infestation levels, damage, and crop loss); testing efficacy of control methods on-station and on-farm; basic economic analysis of new methods; farmer evaluation of new control methods; modeling and econometric analysis; and impact assessment. According to Hodges, estimating postharvest losses helps in influencing policy makers, improving the efficiency of value chains, and identifying opportunities for increasing food security.

Reiterating the economic benefits of storage, Govereh stated: “Most maize is produced by small-scale farmers in one major season and is meant for home consumption. However, consumption is continuous therefore storage is needed to buffer stocks and protect against price fluctuations.”

Connecting people for sustainable agriculture

Father farmer in the field
Father farmer in the field

In Central Mexico, Conservation Agriculture, a more sustainable way of farming, has evolved from being a handful of researchers and a few innovative farmers working off of an idea to a full-fledged network, a system of support and dissemination since its beginnings in 2010. But there are no roots in the historically poor and, at times, politically volatile, Southern States; states that could greatly benefit from a farming system saving labor while ensuring higher productivity. To change this, CIMMYT decided to implement the Conservation Agriculture system in the state of Chiapas with hopes that if things go well, it can act as a gateway to the region.

My first experience with the technology dates back to June 2010, when Bram Govaerts, the head of CIMMYT’s Conservation Agriculture program in Mexico, picked me up outside of a bakery in Mexico City at five in the morning, so we could leave before traffic, some of the worst in the world, became too unruly. We arrived to the first field around seven and were met by a farmer’s eyes underneath a straw hat. At his side was a dog, which did not stray more than a few feet from the farmer, as he explained how rotating his crops had helped cut back on fertilizer use. Thoughtful crop rotation, an important part of Conservation Agriculture, can restore what the previous plant depletes, and thus helps cut down not only on fertilizer use, but also other chemicals, like herbicides, because weeds have more trouble surviving across the change from one crop to another.

Our next visit was to an idyllic field that seemed as if it had been untouched in the last 100 years, except for what looked like raised rows, known in Conservation Agriculture as “beds.” When you till too much, a lot of important nutrients are left loose and exposed to be washed away by rain or picked up by wind. Using special machinery to move the soil less and create these beds helps hold onto what makes soil, well, soil.

Residues
Residues

Fifty minutes later, we parked next to a crosshatch fence where a farmer waited with his family. A granddaughter held a rabbit that upon introduction hopped out of her hands and onto dried maize stalks, known as residues in Conservation Agriculture, covering the field. Leaving behind residues, which are really just part of what is grown, like stalks and stems, helps hold in moisture and protect old soil before decomposing into new soil. We traveled for thirty minutes more and met another farmer. One more hour and the next. And so on until we, dirt under our fingernails, arrived back in Mexico City just after midnight.

Two years later, what continues to resonate are the conversations with Bram. I see now that as we drove from unpaved road to stretched highway I heard his vision for what the young program would become in Mexico. A vision that today is a reality, spreading from Central Mexico to other Mexican states.

In August, I went to Chiapas to see these efforts. Late Friday night I arrived at the new office, where a storm had knocked out the power. The team and I made plans in the dark as we ate leftover sandwiches from a Conservation Agriculture training course earlier that day. The next morning we spoke with a farmer who adopted the technology after farming traditionally for over three decades, a result of having been inspired by the success of his son. We gave a silo to a farmer interested in a different storage option, and he told us how he had been waiting, how he had always believed in people like us as we explained Conservation Agriculture and MasAgro’s work over a cup of pozol made from maize he had sown.

Talking to the farmers taught me a lot about the importance of continuing to learn when faced with new practices. But what lingers more than the farmers are the people spreading this technology. The methods and benefits of Conservation Agriculture can make no difference without the people connecting to one another to explain them. To convince a farmer to go against tradition, against what most of his neighbors perceive as the right way to farm, and against how his parents grew the same crop. That is the real issue. And the team in Chiapas works to address this issue with a combination of skill and heart that is infectious.

Innovative public-private partnership to scale up conservation agriculture in Bangladesh

Infroma-photo-BDDeveloping public-private partnerships (PPPs) to expand conservation agriculture (CA) is one of the main goals of the USAID-funded Cereal Systems Initiative for South Asia in Bangladesh (CSISA-BD). A key stakeholder in CSISA-BD, CIMMYT has partnered with International Development Enterprises (iDE) to develop business models to support Solar International, a leader in the agricultural machinery sector in Bangladesh. To kick-start the PPP, Solar International recently imported 54 seeder-fertilizer drills that can be attached to the ubiquitous two-wheel hand tractors found in Bangladesh, and used for the CA strip tillage technique. Using such machinery allows for rapid precision planting of wheat, reduces the turn-around time before the rice harvest, and responds to the problem of growing labor scarcity for planting in Bangladesh. The PPP prioritizes farmer and service provider training in better-bet agronomic practices, optimum use of the seeder-fertilizer drills, and the marketing of agricultural services to small and marginal farmers at reasonable prices.

In November 2012, supported by CIMMYT, Solar International and iDE completed in-depth training and certification of 108 leading agricultural service providers and their machine operators, who had purchased the seeder-fertilizer drill. To make this approach scalable and sustainable, Solar International embedded the cost of training in the market price of the equipment; emphasizing program sustainability by securing a training and funding source after CSISA-BD withdraws. In turn, CSISA-BD supplied a 50% cost-rebate to purchasing service providers upon successful completion of the training course. This PPP was brokered by CIMMYT’s Timothy J. Krupnik, Cropping Systems Agronomist in Bangladesh, Rajiv Pradhan (iDE), and Sohel Khan (Solar International). Trainings were facilitated by representatives of Solar International, Farhad Hossain (CIMMYT Agricultural Development Officer), Scott Justice (CIMMYT Machinery Consultant), and Shafiq Islam (CIMMYT-CSISA Training and Outreach Officer).

Latin American maize breeders learn about doubled haploids

Doble-Haploid2The use of doubled haploids in maize breeding was first proposed more than half a century ago and dramatically reduces the time required to produce homozygous inbred lines. Though widespread in modern maize breeding programs, the technique is little used by public programs and small- and medium-scale seed companies, especially in developing countries, partly due to its complexity.

To gain greater knowledge and mastery of the theory and actual practice, during 26-30 November 2012, 28 maize breeders from private and public entities of 5 Latin American countries attended a course given in Spanish by CIMMYT maize experts at El Batán. Complementing a similar course given in English last August, the event covered haploid induction, chromosomal doubling, breeding using doubled haploid lines, and how to access CIMMYT’s doubled haploid line production services, including hands-on practice in identifying haploid kernels, the chromosomal doubling treatment, and assessing haploid induction rate.

Doble-Haploid1“This is a cutting-edge technology,” says Tito Clauré, Maize Program Coordinator at Bolivia’s Instituto Nacional Autónomo de Investigaciones Agropecuaria (INIAP). “We’re very happy with what we learned about double haploids, but we also attended excellent presentations on statistics, physiology, and database creation.” Clauré mentions that INIAP’s Maize Program is part of the Sustainable Modernization of Traditional Agriculture (MasAgro) project, and has received much useful germplasm from CIMMYT.

“The course was a very good experience for me,” says Victor Moran Rosas, a breeder at the seed company Semillas Berentsen in Mexico. “I’d read about (doubled haploids), but was able to practice all the steps.” Participants widely agreed that a great part of the course was being able to connect with other Latin American maize breeders.

HarvestPlus wheat varieties fight zinc and iron deficiency in India

DSC04934A series of farmer-scientist interaction meetings to create awareness of HarvestPlus and new biofortified wheat varieties with high zinc and iron content, involve farmers in participatory varietal selection (PVS) of biofortified varieties in the next crop cycle, train farmers on soil sampling for iron and zinc analysis, and discuss seed and wheat production technology, took place in eastern Uttar Pradesh, India, in November 2012. The meetings were held in Bhurkura, Mirzapur district, on 4 November, Sota, Chandouli district, on 10 November, and Pidkhir, Mirzapur district, on 18 November, and were attended by 25, 38, and 30 farmers, respectively. They were jointly organized by the Banaras Hindu University, Mahamana Krishak Samiti farmers’ cooperative, Mirzapur district, and CIMMYT, and supported by a private seed company M/s. Shyam Seed.

Balasubramaniam Arun, Ramesh Chand, and Vinod Kumar Mishra, wheat scientists from the Banaras Hindu University, introduced the HarvestPlus project’s objectives and the importance of biofortified wheat varieties. Chandra Prakash Srivastava explained the role of zinc and iron for human health, while soil scientist Satish Kumar Singh focused on their role and importance in crop production, as well as zinc level distribution in different soil types in the ricewheat growing areas of the region. Each meeting included a hands-on training on HarvestPlus trials sowing, during which farmers learned about experimental design with focus on plot area, number of lines, and amount of seed to be sown, and which included soil samples collection demonstrations. This was followed by a discussion on the use of conventional and zero-till drill for experiment planting, and the farmers’ experience with biofortified varieties, seed purity maintenance, and the use of the progeny row method. Balanced use of nitrogen, phosphorus, potassium, zinc, sulfur, and boron based on soil analysis was also covered.

CIMMYT wheat breeder Arun Joshi described the steps involved in quality seed production and the importance of seed producers’ organizations for small-scale farmers. He also highlighted advantages of the PVS approach, including the increased adoption rate of new varieties within a shorter period of time. Joshi appreciated the keen interest and active participation of farmers in PVS programs and encouraged them to continue their work and facilitate varietal selection to identify and promote agronomically superior biofortified varieties. The participating farmers showed their interest in HarvestPlus experiments and their continuing support for the wheat biofortification program. They expressed their full satisfaction with the interaction meetings, as these help them to build confidence and enhance their knowledge and capacity for understanding new wheat research processes and results. According to the participants, smallholder farmers have achieved significant gains through the participatory research program, an easier access to new varieties being one of them. Sri Hari Kirtan Singh of M/s. Shyam Seed agreed to multiply all lead varieties seeds identified for high zinc and iron content to allow easy access to an even larger number of farmers.

Abdu Rahman Beshir, a CIMMYT graduate research fellow from Ethiopia, received an award for the best project in the PhD category at a recent Postgraduate Students’ Symposium on Botany and Plant Biotechnology at the University of Johannesburg (UJ) for his paper titled ‘Quality Protein Maize: towards achieving the Millennium Development Goals through better nutrition and stable yields.’ His presentation highlighted the severity of malnutrition in parts of sub-Saharan Africa and the ways quality protein maize (QPM) seeks to address the issue.

Beshir conducted his field research between July 2009 and December 2011 at CIMMYT Kenya, Zimbabwe, and Ethiopia in collaboration with national programs and with support from the Drought Tolerant Maize in Africa (DTMA) Initiative and the Quality Protein Maize Development project. Beshir focuses on the evaluation of yield and secondary traits of early maturing QPM cultivars (both hybrids and open pollinated varieties) under different mega environments of sub-Saharan Africa (his research was featured in Informa 1689).
