More than 120 researchers, policymakers and other stakeholders participated in a commercial hybrid demonstration and maize brainstorming sessions organized by the Directorate of Maize Research, Indian Council of Agricultural Research (ICAR). The National Demonstration of Maize Commercial Hybrids and sessions were held 21-22 September in New Delhi.

The event demonstrated 106 maize hybrids, including leading hybrids from the public and private sectors. Visitors included S. Ayyappan, ICAR Director General; Ashish Bahuguna, secretary of the Department of Agriculture and Cooperation for the Government of India; H.S. Gupta, director of the Indian Agricultural Research Institute; B.S. Dhillon, vice chancellor of Punjab Agricultural University; J.S. Sandhu, commissioner of agriculture; R.P. Dua, assistant director general of food and fodder crops; J.S. Chauhan, assistant director general of seeds; S. Mauria, assistant director general of intellectual property & technology management; and more than 100 researchers from the national agricultural research system. P.H. Zaidi, B.S. Vivek and A.R. Sadananda from the Global Maize Program based in Hyderabad represented CIMMYT.

While visiting the demonstration, Ayyappan said he was impressed with the national maize program’s efforts to develop diverse maize hybrids that meet farmers’ needs in India’s different agro-ecological regions. He lauded the development and fine-tuning of maize production technology that has resulted in many improvements in the last decade. Bahuguna said the initiative was a unique showcase of hybrid technology that can improve farmers’ income. Providing farmers with a wide variety of hybrids can help achieve crop diversification in different regions, he noted. Bahuguna was also interested in new hybrids likely to be available to farmers in the near future.

Gupta emphasized the opportunities that exist to replace low-yielding, traditional maize varieties with hybrids, while Dhillon highlighted the importance of an effective seed production program to fully harness the hybrids’ benefits. Other topics included the objective of the demonstration and how to expand the scale of hybrid initiatives. Chauhan said the demonstration exhibited the strength of public research and development. Three brainstorming sessions – “Public-Private Partnerships,” “Trait Prioritization in Breeding” and “Improving Drought Tolerance” – followed the demonstration. They were led by S.K. Datta, deputy assistant director general for crop sciences, B.S. Dhillon and Sain Das, while Vivek and Zaidi contributed as panelists. More than 100 personnel from the public and private sectors participated. Datta underlined the role of both sectors and called upon scientists to identify areas where they can work together.

A long-time colleague of CIMMYT received the inaugural 2013 World Agriculture Prize from the Global Confederation of Higher Education Associations for the Agricultural and Life Sciences (GCHERA), which recognizes contributions to the field by a university faculty member. Ronnie Coffman, international professor of plant breeding at Cornell University and director of the Durable Rust Resistance in Wheat project, was awarded the prize for his leadership in crop improvement, the prize committee said. He received the award on 20 October during GCHERA’s annual meeting in China.

Ronnie-Coffman

“The world’s farmers need access to the best science that the many great institutions of GCHERA can deliver in order to produce crops that are nutritionally adequate and best-adapted to future challenges,” Coffman said during his acceptance speech, according to GCHERA. Coffman spent a year as a visiting scientist with CIMMYT’s wheat program in 1970 and has continually collaborated with the organization since then. Norman Borlaug, the late CIMMYT wheat scientist and Nobel Peace Laureate, supervised Coffman when he was a graduate student, and the two worked together to address the stem rust disease race Ug99 and other wheat diseases.

Coffman is vice chair of the Borlaug Global Rust Initiative, which was established to respond to wheat disease threats. He worked in the Philippines as a rice breeder for the International Rice Research Institute in the 1970s, where he developed new varieties, before joining the Cornell faculty in 1981. More recently, he has focused on fighting wheat diseases and mentoring students. Coffman has served on the board of various CGIAR centers, including the International Center for Agricultural Research in Dry Areas (ICARDA) and the International Crops Research Institute for the Semi-Arid Tropics. (ICRISAT) Coffman is also a confirmed speaker for the Borlaug Summit on Wheat for Food Security, a Borlaug 100 event that CIMMYT will host in March 2014.

Over the past five years, more than a dozen new stress tolerant wheat varieties have become available to farmers in South Asia, through breeding research and partnerships as part of the Cereal Systems Initiative for South Asia (CSISA), according to Arun K. Joshi, CIMMYT wheat breeder. Joshi said that germplasm exchange with CIMMYT had increased significantly; that most advanced breeding lines in CIMMYT trials were resistant to Ug99 stem rust and other rusts; more segregating generation lines from South Asia were being sent to Njoro, Kenya, for stem rust resistance screening; the use of physiological tools to select for heat and drought tolerance in the region had increased; links among breeders, seed producers and farmers had strengthened; and capacity building had been promoted.

These and other achievements, as well as challenges and opportunities for improvement, came to light in two recent review meetings in Dhaka, Bangladesh. From 6 to 8 October, 56 scientists from Bangladesh, Bhutan, India and Nepal, as well as representatives of government councils and ministries, research centers, agricultural institutes and universities, convened for CSISA’s 5th wheat breeding review meeting. Participants also attended the 2nd review and work plan meeting for the project, “Increasing the productivity of the wheat crop under conditions of rising temperatures and water scarcity in South Asia,” funded by the Federal Ministry for Economic Cooperation and Development, Germany. The meetings were organized by Joshi, team leader of the two projects in South Asia, and facilitated by CIMMYT’s Dhaka office, led by T.P. Tiwari. CIMMYT was represented in the meetings by scientists from Bangladesh, India and Nepal and a consultant from Cambridge.

The CSISA meeting reviewed the progress of the 2012-13 wheat cycle and established work plans for the 2013-14 crop cycle. The event was inaugurated by chief guest Khalid Sultan, director of research at the Bangladesh Agricultural Research Institute (BARI), and R.P. Dua, assistant director general for the Indian Council of Agricultural research (ICAR). Dua praised the regional focus and presence of CSISA wheat breeding, and Sultan said “the South Asia-CIMMYT collaboration is paramount to the food security of the region.” Ten participating research centers presented reports and work plans.

Participants discussed how to strengthen links among wheat breeding, fast-track seed production, distribute new, improved varieties to farmers and work on conservation agriculture and participatory variety selection. Wheat breeders, pathologists, physiologists, agronomists and soil scientists attended the “Increasing the productivity of the wheat crop” meeting, which addressed project work plans and progress in breeding and agronomy.

Six Indian research centers reported on progress in evaluating more than 3,300 wheat lines screened last cycle for early sowing, as well as the 2013-14 work plan. The top 50 lines will be used to develop two trials in India: one for the northwestern plains and one for the central and peninsular zone, Joshi said. He also presented the highlights of the molecular research by Marion Roder, Leibniz Institute of Plant Genetics and Crop Plant Research, Germany, and Susanne Dreisigacker, CIMMYT molecular breeder, in screening some 3,000 wheat lines for genes controlling vernalization and response to changes in day length.

A meeting last month highlighted the efforts of the Pakistan Agricultural Research Council (PARC) and CIMMYT to improve wheat in the country. PARC and CIMMYT-Pakistan organized the annual wheat planning and Wheat Productivity Enhancement Program (W-PEP) meeting from 17 to 18 September at the National Agriculture Research Centre (NARC) in Islamabad. PARC2

The meeting reviewed progress and achievements during the last three years under the United States Department of Agriculture (USDA) funded W-PEP program and refined work plans for 2013-14. The program is aimed primarily at developing wheat varieties that resist Ug99 stem rust as well as fostering seed multiplication and distribution, improved agronomic practices and human resource development in the agriculture sector to ensure food security. During the inaugural session, USDA Agriculture Counselor Clay Hamilton said the USA and Pakistan have a long history of agricultural collaboration. The U.S. will continue to provide support for wheat productivity in Pakistan, he said.

Shahid Masood, PARC scientist from the Plant Sciences Division, highlighted PARC’s role in strengthening the national and provincial agricultural research system in coordination with national and international collaborators and research partners. Imtiaz Muhammad, CIMMYT country liaison officer for Pakistan, briefed the participants about W-PEP’s achievements during last three years and the impact of this program on the national wheat research system in rust surveillance, breeding, pre-breeding and capacity building, which led to the release of Ug-99 resistant wheat varieties like NARC-2011. National partners from all provinces, including Azad Jammu and Kashmir and Gilgit Baltistan, presented their achievements and work plans for 2013-14. They acknowledged the role of USDA, CIMMYT and PARC in supporting wheat productivity enhancement in Pakistan.

Jharkhand tribal farmers adopt maize and conservation agriculture to battle drought

Jharkhand By S.P. Poonia/CIMMYT

A CIMMYT project working in the rural districts of Jharkhand, India, is encouraging farmers to grow maize and use conservation agriculture practices to adapt to decreased rainfall and a changing climate. CIMMYT’s Sustainable Intensification of Smallholder Maize-Livestock Farming Systems in Hill Areas of South Asia project is funded by the International Fund for Agricultural Development.

The project is working with scientists from Krishi Vigyan Kendras research and extension centers (KVKs), Birsa Agricultural University, the state agricultural department and farmers to promote maize as a viable alternative to rice in stress-prone and rain-dependent districts of Jharkhand. The rural farming population is vulnerable to rainfall fluctuations and drought is recurrent in Jharkhand. Almost 90 percent of the cultivated area is monocropped (mostly with rice), and only 9 percent of the cropped area is irrigated.

The local non-governmental organization Vikash Bharti Farm Science Centre and CIMMYT organized Maize Day on 29 August in Gumla district. The event brought together 400 farmers, state agricultural department scientists, district officials and extension agents to highlight the benefits of cultivating maize, using conservation agriculture to enhance productivity. They also discussed the need for better policies. “Quality protein maize (QPM) is nutritionally superior to normal maize and provides additional dietary benefits to the tribal farmers who consume maize. It’s also a nutritious feed for poultry,” said A.K. Singh, KVKs zonal director for the Indian Council of Agricultural Research.

In Basuwa village in Gumla district, farmers cultivated more than 80 hectares of the QPM hybrid HQPM 1 for the first time this year and have committed to increase maize cultivation to 323 hectares next year. “Earlier, farmers in my village were interested in growing only rain-fed rice because it’s their staple food,” said Joni Uraon, head of the Basuwa village council. “But now they are very happy with maize because it is giving them higher profits.” Farmers also asked for stronger market linkages to ensure competitive prices for their produce. Panai Uraon, the Gumla district government collector, welcomed the efforts of scientists and farmers to promote maize cultivation and announced additional funds will be allocated to the Basuwa village council for agricultural development activities and to supplement local irrigation systems. Ken Sayre, who has extensive knowledge of Turkey and the region, conducted the course. He also travelled to three key research institutes in Ankara, Eskisehir and Konya prior to the workshop to see the experimental fields and discuss how to reduce variability in the fields and enhance the precision of experiments.

Pakistan program aims for agricultural innovation

WPEP-AIP-meeting By Imtiaz Muhammad/CIMMYT

International and Pakistani scientists are expanding efforts to accelerate access to climate-resilient maize and rust-resistant wheat varieties in Pakistan, as well as to improve farmers’ access to quality seeds, as part of the Agricultural Innovation Program (AIP). Project partners discussed these priorities during a cereals and cereal systems meeting at the National Agricultural Research Center (NARC) in Islamabad from 29 to 30 August. AIP is a U.S. Agency for International Development (USAID)- funded project focusing on cereals, vegetables and livestock in Pakistan, a country challenged by rapid population growth and climate change.

CIMMYT is working with the Pakistan Agricultural Research Council (PARC), the International Rice Research Institute (IRRI) and other partners to increase agricultural productivity and the value of agricultural commodities in the country. The program is supporting Pakistan in agricultural research for development, which includes building partnerships between research and those it serves; increasing investments; generating, sharing and making use of agricultural knowledge for development; and demonstrating and building awareness of the development impact and returns from agricultural innovation. Farmers throughout the world face similar problems from increasing production costs, fluctuating market prices, water and soil degradation and potential implications of climate change, said Ken Sayre, a CIMMYT consultant on conservation agriculture. Sayre also described the benefits of conservation agriculture crop management technologies and their main principles.

These include seeding systems that allow major reductions in tillage, retaining adequate levels of crop residues on the soil surface and using diversified crop rotations. There are many challenges AIP can address. Maize yields in Khyber Pakhtunkhwa Province are low due to a lack of technology. Most maize farmers in Pakistan use manual sowing, which is not cost or time-effective, and farmers need more confidence in hybrid seeds before they will pay a premium for them. Meeting participants discussed several options for commissioned projects in wheat, including rapid diffusion of high-yielding, rust-resistant wheat; introducing fungicides for wheat management; and generating a durum wheat value chain in Pakistan. Participants also discussed potential projects and goals related to climate-resilient wheat, the cultivation of durum wheat in Balochistan province, the standardization of fungicides to combat yield losses and strengthening communication.

For the rice work plan, top priority areas include developing tolerance to submergence and heat in locally adapted varieties such as super basmati, basmati 515, IR-6 and IR 9, in addition to bacterial leaf blight resistance and superior grain quality. Abdul Rehman and Surapong Sarkarung represented IRRI, where some of the activities have already begun. Priorities for the maize work plan include introducing climateresilient maize hybrids, developing biofortified maize, developing cultivars with resistance to biotic stresses and strengthening the maize seed sector. CIMMYT maize expert R. Sadananda and national partners joined to refine the maize work plan. Kay Simmons from the U.S. Department of Agriculture (USDA)-Agricultural Research Service and Ian C. Winborne, plant health advisor for the USDA Animal and Plant Health Inspection Service at the U.S. Embassy in Islamabad, also attended the meeting to discuss wheat productivity enhancement in Pakistan.

A three-day travelling seminar organized by CIMMYT’s Hill Maize Research Project (HMRP) and partners gave policy makers a first-hand look at the status of maize varietal development, source seed production, agronomic interventions and seed multiplication and marketing in 20 districts of Nepal. In close partnership with the Nepal Agriculture Research Council (NARC) and the Department of Agriculture (DoA), HRMP hosted this third annual seminar from 27 to 30 August for 25 officials representing donors such as the Swiss Agency for Development and Cooperation (SDC) and the United States Agency for International Development (USAID), as well as organizations including the National Planning Commission, Ministry of Agriculture Development (MoAD), Ministry of Finance, non-government organizations, private companies and the media.

Participants visited a variety of sites. At the Agriculture Research Station (ARS) in the district of Dailekh, attendees interacted with scientists and observed maize research activities and conservation agriculture trials. In this area, the project is promoting intercropping white quality protein maize (Poshilo Makai-1) and off-season vegetables such as bitter gourd, tomatoes and radishes. HIV/AIDS infected women farmers in Rakam village of Dailekh were also invited to participate. “Our main resource is land,” said 30-year-old farmer Mana Sara Sijapati during a group discussion. “We must increase our production from this land to have food security in our households during the entire year.” She asked the participants for a program targeted toward farmers affected by HIV/AIDS. Ram Prasad Pulami, joint secretary at the MoAD, asked NARC and DoA representatives to respond to the request immediately.

The group then participated in an interactive program with farmers, observed seed production activities and assessed on-farm trials and demonstration plots at the Basnatamala and Jeevanjyoti Women Community Based Seed Production (CBSP) Group. Dr. G. Ortiz-Ferrara, team leader for HMRP/CIMMYT, and Pulami jointly inaugurated an HMRPfunded seed store house that was built for the CBSP group. The team also visited the Sambriddhi Agriculture Cooperative, Ltd., as well as a quality protein maize village, where conservation agriculture trials will soon be established. Ortiz-Ferrara thanked all the participants, including the HMRP team, for their active participation and support in making the seminar successful. Pulami said during his closing remarks that he appreciated HMRP’s efforts and progress, especially the partnerships between the project and a number of diverse stakeholders. He said the government of Nepal is implementing a “Mid-hill Mega Maize Production Program” focused on 40 hill districts and will utilize HMRP’s experiences and research innovations.

Project spotlight: the Hill Maize Research Project

Beginning in August, the Hill Maize Research Project (HMRP-IV), has worked with the Seed Entrepreneurs Association of Nepal and the District Agriculture Development Office to facilitate formal contracts between 51 community-based seed production (CBSP) groups and 25 seed buyers/traders for a total of 201 tons of improved seed of different maize varieties. Of the total contracted seed, seed companies account for 55 percent; agrovets, 20 percent; community seed banks, 13 percent; and cooperatives, 12 percent.

Launched in 1999, HMRP is in its fourth phase. The project focuses on improving the food security and income of resource-poor farm households in the hills of Nepal by raising the productivity, sustainability and profitability of maize-based cropping systems. Work now covers 20 hill districts of Nepal and is jointly funded by the Swiss Agency for Development and Cooperation (SDC) and the United States Agency for International Development (USAID). CIMMYT implements the project in partnership with an array of public and private sector institutions in Nepal. Principal partners include the National Maize Research Program under the Nepal Agricultural Research Council, the Crop Development Directorate under the Department of Agriculture, the Seed Quality Control Centre and the National Seed Board under the Ministry of Agriculture Development. Other partners include community-based organizations, farmer groups, NGOs, private entrepreneurs, seed companies and universities.

Community Based Maize Seed Production
The project began multiplying seed of improved maize varieties through CBSP groups in 2000. That year, about 14 tons of improved maize seed were produced by seven CBSP groups. By 2011, more than 1,140 tons of improved maize seed were produced by 195 CBSP groups and, in 2012, 207 groups produced 1,036 tons. Of the total marketable surplus seed produced in 2011, about 75.1 percent was marketed or exchanged, compared to 83.3 percent in 2012. The seed was marketed mainly across the 20 hill districts of the HMRP project area. Seed production through CBSP groups has been a successful model in Nepal and has contributed to increasing the adoption of improved maize varieties and technologies. The CBSP model helps ensure the availability of improved maize seed in remote hill areas on time at lower prices.

Pre-sowing seed contract
Maize seed marketing is one of HMRP’s major challenges. Until 2012, CBSP groups did not consider the supply and demand in markets, resulting in surplus seed in some areas and deficits in others. The 2013 project phase initiated pre-sowing seed contracts for improved maize varieties, assisting and guiding CBSP groups and seed buyers/traders (agrovets, community seed bank cooperatives and seed companies) to sign formal agreements.

The Farm Mechanization and Conservation Agriculture for Sustainable Intensification (FACASI) project is addressing the decline of farm power in Africa. The project is working with smallholder farmers to deliver small mechanization based on inexpensive, two-wheel tractors and introduce power-saving technologies, such as conservation agriculture.

Last March, participants evaluated the performance of the Gongli seeder – a seed drill sold in China – under the typical conditions of maize smallholder farmers in Kenya and Tanzania. Gongli inventor Jeff Esdaile, engineers from the Centre for Agricultural Mechanization and Rural Technology (CAMATEC) and engineers from the Kenya Network for Dissemination of Agricultural Technologies met at a CAMATEC workshop from 9 to 20 September in Arusha, Tanzania, to modify the Gongli seeder and produce the Gongli Africa +. The original Gongli seeder is well suited to seed small-grain crops in close rows into fields without long, loose residue or heavy weeds. For sowing maize in a typical field around Arusha, however, the machine had several shortfalls: it handled loose maize residues and heavy weeds poorly; the pressing wheels got in the way of the operator’s walk; the seed and fertilizer hoppers were too high and blocked the operator’s visibility; the seed meters were not precise enough for maize planting; and transporting the machine from field to field required walking long distances because the machine cannot be ridden and does not fit in a trailer.

The modified Gongli Africa + features cutting discs that can be fitted in front of the standard tines for heavy mulch and weed loads. Two large back tires, used as pressing wheels in the field, were added, as well as a platform for the operator to stand on, facilitating transport to and from the fields. Because the machine will be used to sow a maximum of two rows, the third bar was removed from the seeder. The seed and fertilizer hoppers were lowered, and, finally, specialized seed metering systems for large seeds such as those of maize were installed. Results from initial field testing were encouraging. Thorough field testing will take place next November in Tanzania and Kenya. After minor modifications, the specifications of the Gongli Africa + will be sent to Gongli LTD for commercial manufacturing.

New facility investigates the hidden half of maize

Written by on September 30, 2013. Posted in News.

By P.H. Zaidi/CIMMYT

A new facility at CIMMYT-Hyderabad, India, will allow researchers to assess and quantify key root traits and their dynamics under various growing conditions. CIMMYT’s new root phenotyping facility is based on the lysimetric system, by which scientists can directly assess and quantify root traits and their dynamics under various growing conditions. It also allows high-precision phenotyping of various root traits.

The system revolutionizes the research, moving from a static assessment of roots through time-consuming extraction and scanning to a real-time measurement of water uptake, water use and an assessment of variation in roots under different growing conditions in the rhizosphere. Recent advances in high-precision weighing systems and information technology tools have greatly improved its efficiency and effectiveness as a root phenotyping system.

CIMMYT’s root phenotyping facility is specially designed for – but not restricted to – maize. The facility features 2,400 minirhizotron observation tubes placed in eight concrete pits. A wheeled stand is used to lift the rhizotrons for weighing. The weight of the cylinder, along with the entire plant, is monitored periodically and allows researchers to estimate the amount of water used and transpired as well as the transpiration efficiency of different genotypes. Roots are critically important to plants because they are the part first exposed to any soil-mediated stresses, such as drought, waterlogging, salt stress or nutrient stress. Root traits govern the overall performance of plants; however, this important hidden half is often avoided due to the complexity involved in studying root structure and functions.

In maize, the genotypic variation in root traits and variation under stresses can be carefully selected in targeted breeding for stress tolerance, which can contribute significantly to genetic gains. Root traits are often judged on the basis of related characteristics, which may not accurately explain the stress-responsive — or adaptive — structural and functional changes in roots under sub-optimal or stressed conditions. The facility is used in phenotyping root traits of mapping populations developed for various molecular breeding projects on drought and heat stress tolerance as well as other traits usually observed in field conditions, including morphological traits and grain yield. It is located under a renovated rain shelter, protecting the trials from rain at the targeted crop stage and allowing for yearround use.

CIMMYT is grateful to the Syngenta Foundation for Sustainable Agriculture for its financial support of the facility and the International Crops Research Institute for the Semi- Arid Tropics for providing space and other logistic support in establishing this unique facility.

CIMMYT wheat research interests future scientists

Wheat research is an intriguing story to many. CIMMYT’s Global Wheat Program (GWP) keeps germplasm flowing worldwide, and more than 100 wheat researchers and 40 junior scientists and graduate students attend its annual wheat improvement course. The program hosted students from around the world in 2013, introducing them to the program’s critically important work.

Visit to wheat research station at Ciudad Obregón

The GWP hosted a visit from 10 to 11 April for 50 children, ages 8 to 12, who are part of the PERAJ program at the Instituto Tecnológico de Sonora (ITSON). The university’s “adopt a friend” program encourages students to tutor children from public primary schools in Ciudad Obregon. The CIMMYT visit originated from the daughter-mother link of Carolina Rivera Amado, a Ph.D. student in the MasAgro program, and Alma Amado Quintana, the PERAJ coordinator at ITSON. Alma Amado said the program creates relationships between the tutors and their “adopted” students to support education and strengthen the professional and personal development of ITSON students. The children and their tutors were intrigued by the diversity of wheat. They learned the source of their favorite wheat tortillas and discovered the work scientists do to increase wheat productivity. The experience allowed Mathew Reynolds and colleagues Araceli Torres, Carolina Rivera, Arnauld Thiry and Perla Chávez to explain how plants grow and for Amor Yahyaoui to explain how scientists ensure the production of healthy plants.

Yokohama City University (YCU) students visit CIMMYT headquarters

Seven undergraduate students came to CIMMYT’s headquarters from Japan’s Yokohama City University (YCU) from 6 to 7 August to tour facilities and interact with wheat and maize scientists. The overall objective of the visit was to expose the students to international agricultural research on crop improvement and to give them an opportunity to meet worldleaders in research helping to feed the world. Through the efforts of Tomohiro Ban, a former CIMMYT scientist who is a lead researcher at the Kihara Institute for Biological Research (KIBR) and his working relationship with wheat scientist Ravi Singh, young undergraduates from Japan visit CIMMYT almost every year. CIMMYT scientists who interacted with the group included Singh, Jose Juan Caballero, Sehgal Deepmala, Bibiana Espinosa, Velu Govindan, Julio Huerta, Masahiro Kishii, Aleksandre Loladze, Monica Mezzalama, Henry Ngugi, Tom Payne, Pawan Singh, Sukhwinder Singh, Prashant Vikram, He Xinyao and Amor Yahyaoui. The students were introduced to CIMMYT’s global maize and wheat research programs as well as training activities in the fields of breeding and genetics, pathology, biotechnology, seeds of discovery and bio-fortification research. The visit to the new Bioscience Complex showed the students the steps in wheat variety development from DNA analysis to field plot techniques. “I learned about the importance of connecting biotechnology and breeding,” said Yuki Kajita, a student participating in the visit. “I had a very good time at CIMMYT. I hope to come again someday as a researcher.”

Tokyo university students visit CIMMYT

Tokyo University of Agriculture also organized a visit to CIMMYT headquarters. On 12 August, a group of 12 students visited as part of their tour abroad to agricultural research institutions and to learn about agricultural activities of smallholder farmers in Mexico. The students toured the gene bank and learned about seed selection and treatment as part of CIMMYT’s international nursery activities. They also visited wheat and maize demonstration plots and were encouraged to consider CIMMYT as they continue with their post-graduate research. The group was headed by Mariko Kawaminami, agronomist and professor at the University of Chapingo. This tour is organized and hosted by the University of Chapingo every year as part of its international academic exchange activities.

Afghanistan capacity development supported by Japanese Institutions

Representatives from several institutions working on the Development of Wheat Breeding Materials for Sustainable Food Production (SATREPS) project visited CIMMYT on 28 February to encourage support for young Afghan scientists and capacity development of young Japanese researchers and students. SATREPS aims to train Afghan scientists in the development of wheat breeding materials for sustainable food production through partnerships with Afghanistan, Japan and Mexico. Japanese institutions involved in the project include KIBR, Yokohama City University, the Science and Technology Agency (JST) and the Japan International Cooperation Agency (JICA). The project also sponsored two Afghan scientists to join the CIMMYT Global Wheat Program wheat improvement course in Ciudad Obregón from March to May. Lead scientists in breeding, physiology, pathology and biotechnology helped participants to acquire practical experience in wheat breeding. Zahery Eid Mohammad and Ahmadi S. Hasibullah completed the training and are registered for master’s studies at Yokohama City University. CIMMYT will continue to strengthen the Japan-Mexico collaboration by training young Afghan scientists and encouraging young Japanese students to get involved in agricultural research.

Increased access to seeds better suited for local conditions and climate-smart crop management technologies are two strategies Bioversity International and CIMMYT India are using to improve the climate change resilience of resource-poor farmers. With the 14 August visit of Bioversity International Director General Ann Tutwiler to the Borlaug Institute for South Asia (BISA) Pusa site and the climate-smart villages in the Vaishali district of Bihar, this partnership has strengthened and will work to improve farmers’ coping and adaptation to climate change in eastern India. The groups are working under Climate Change, Agriculture and Food Security (CCAFS).

Agriculture is affected by variable temperatures and erratic climate events. Smallholder farmers who are impacted suffer from low production and increasing costs. Tutwiler said that CIMMYT, BISA and Bioversity have common interests and should complement each other’s work in making smallholder farmers climatesmart through local adaptation of stress-tolerant seeds and integrating them with better agronomic management. The greatest need is in multi-stakeholder partnerships and to apply collective wisdom to address these challenges for farmers’ benefits, she said.

Tutwiler and other visitors saw strategic research on conservation agriculture at the BISA farm as well as collaborative research between CIMMYT and the Indian Agricultural Research Institute (IARI). Participants discussed the long-term benefits of conservation agriculture, such as increased productivity, improved soil fertility, cost savings and reduction of greenhouse gas emissions. “At Pusa, we have established long-term research on conservation agriculture in predominant cropping systems to monitor and devise resilient future cropping systems and their component technologies for the eastern Indo Gangetic Plains,” said M.L. Jat, a CIMMYT senior cropping systems agronomist. “These work as capacity-building platforms for various stakeholders.”

The team also saw climate-smart technologies promoted by CIMMYT in collaboration with other CGIAR centers and national agricultural research and extension services under CCAFS. Mamta Kumari, a woman farmer from the climate-smart village Rajapakar said, “Rainfall has been unreliable for the last few years. Our crops and livelihoods are at risk with changing weather. But we are now getting more information about new seed, methods and technologies; we can see a change.” With access to timely information on weather, better-adapted seeds and improved crop management, women farmers are now feeling more empowered. “We are saving around 5,000 Rupees (about US$79) on the cost of production using zero tillage in wheat cultivation,” Kumari said. Tutwiler met and shared her experiences with CIMMYT Director General Thomas Lumpkin and discussed common goals of Bioversity, BISA and CIMMYT to improve lives of farmers under changing climate conditions

Women farmers in India are learning about the benefits of biofortified wheat from CIMMYT and other CGIAR researchers. Scientists met with 106 women on 8 August in the village of Pidkhir, in Mirzapur District of Uttar Pradesh, India, to advocate for the use of biofortified wheat and listen to feedback on nutrition and the impacts of nutritional deficiency on women and children.

The event was part of a program conducted in more than 50 villages in India’s Eastern Gangetic Plains. Collaborators included Banaras Hindu University (BHU) in Varanasi, Mahamana Krishak Samiti (a farmers’ cooperative in Mirzapur) and CIMMYT’s South Asia office in Kathmandu, Nepal. BHU’s Chhavi Tiwari led the meeting in Pidkhir, which was attended by women of different ages and occupations including farmers, housewives, daily wage workers, government organization workers and school teachers. Other participating scientists included B. Arun, Ramesh Chand and V.K. Mishra from the BHU HarvestPlus wheat team as well as Arun Joshi from CIMMYT.

The HarvestPlus project was started at BHU in 2005 as part of a collaborative effort with the Biofortification Challenge Program (HarvestPlus) at the International Center for Tropical Agriculture, the International Food Policy Research Institute and CIMMYT to identify biofortified wheat varieties adapted in South Asia. Five of the participants at the meeting participated in the HarvestPlus trials in Pidkhir that began in 2005 and said they were happy with the wheat variety. “I cannot believe that wheat with high zinc and iron could be grown in our fields in the near future,” said Sursati, a woman working with HarvestPlus wheat throughout the course of the project. Most participants were new to the subject and learned about the importance of biofortified wheat – particularly its importance to the health of women and children. Women also answered a questionnaire on their backgrounds and interests in biofortified wheat. Most were educated through primary school and some were given help by literate peers. Four male farmers from Pidkhir, including Harbans Singh, head of the Mahamana Krishak Cooperative, also facilitated the process.

All of the women were in favor of receiving biofortified wheat developed through the HarvestPlus project. They also expressed their desire to visit and see the BHU research farm, where wheat scientists from the university are conducting research with CIMMYT’s Global Wheat Program team. The farmers agreed to advocate for new biofortified wheat varieties and help the BHU team when needed.

Twenty young scientists from India and Nepal learned about existing and up-and-coming wheat breeding tools during a training program last month. Continuing earlier training programs initiated during the last few wheat crop cycles in India, the Global Wheat Program in South Asia organized the three-day “ICAR-CIMMYT Molecular Breeding Course in Wheat” from 25 to 27 August. It took place at the Directorate of Wheat Research (DWR) of the Indian Council of Agricultural Research in Karnal.

ICAR-CIMMYT The training was for young scientists from different wheat research stations of India involved in a BMZ-funded project to increase the productivity of wheat under rising temperatures and water scarcity in South Asia. The training program attendees’ enhanced understanding of existing molecular tools for wheat breeding as well as emerging tools such as genomic selection. “Molecular tools will play an increasing role in wheat breeding to meet challenges in coming decades,” said Indu Sharma, director of DWR in Karnal. The program covered both theory and practice on the use of molecular makers in wheat breeding, especially those related to vernalization, photoperiodism and earliness per se, which could be used to enhance early heat tolerance. Practical sessions in the molecular laboratory of DWR focused on extraction of DNA, quantification and quality control of DNA, polymerase chain reaction polymerase chain reaction amplification and electrophoresis.

During various sessions, the instructors explained the steps of molecular tools to be used for such work. The participants tested their new scoring skills during an exercise which involved scoring the bands and cross-verifying results. Laboratory procedures on safety were also explained. CIMMYT wheat breeder Arun Joshi and Vinod Tiwari, principal scientist and principal investigator of crop improvement for DWR in Karnal, coordinated the training under the WHEAT CRP Strategic Initiative 6 (enhanced heat and drought tolerance). Indian resource participants included Ratan Tiwari, P.K. Gupta, Vinod Tiwari and a team of molecular scientists including Rajender Singh, Rekha Malik, Sonia Sheoran and Pradeep Sharma from DWR, Karnal. The CIMMYT scientists involved were Susanne Dreisigacker and Arun Joshi while the practical lessons were organized and led by Tiwari and Dreisigacker. A laboratory manual “ICAR-CIMMYT molecular breeding course in wheat” was also developed for the course, which was later released in the All India Wheat and Barley Workers meeting.
