In response to rapidly-changing food preferences in Pakistan, including a latent unmet demand for pasta products, CIMMYT-Pakistan has been working to develop the country’s durum wheat market and varieties that satisfy the required grain quality attributes, in addition to high yields and disease resistance.

According a 2014 study by the Woodrow Wilson International Center for Scholars, Pakistan is urbanizing at an annual rate of 3 percent—the fastest pace in South Asia. “More Pakistanis are living in cities than ever before,” said Krishna Dev Joshi, CIMMYT wheat improvement specialist. “As a result, demand for durum wheat products like macaroni or spaghetti is rising. But farmers are not growing durum wheat because there is no a clear price advantage or assured markets. At the same time, private investors will not develop new milling facilities or markets without guarantees of durum wheat grain supplies from farmers.”

To help break the impasse, CIMMYT has been testing and evaluating 925 durum wheat lines in Pakistan since 2011, and identified 40 durum wheat lines as having appropriate combinations of high yield, protein, yellowness and sedimentation. The yield stability of lines across locations and years indicates that durum wheat could be grown in environments similar to those of the trial sites, increasing the chances for uptake of this new crop. “One challenge, though,” said Joshi, “is that durum yields were only slightly higher than those of bread wheat, posing a challenge for the uptake by farmers of durum wheat.”

Activating Durum Markets from the Ground Up

The Center also led a 2014 durum value chain study involving 85 respondents including farmers, millers, the processing industry, restaurants, seed companies, grain dealers and consumers across five locations. They were queried regarding their awareness of durum wheat, as well its production, usage and future prospects in Pakistan. “A complete lack of durum milling technology is the main obstacle to commercializing this crop,” Joshi said.

Value chain actors themselves were only marginally aware of durum wheat and associated technologies. However, 60% of millers stated they would be willing to invest in durum wheat if it became an openly-traded commodity, policies fostered market price premiums, durum milling machinery could be acquired at subsidized rates and local and foreign manufacturers were linked.

For durum wheat production to take hold in Pakistan, milling technology would have to be adapted or farmers would have to find a niche in the international market. Government support is necessary in either case.

Despite these challenges, the durum wheat market is slowly being developed. The first national durum wheat workshop in Pakistan last September brought together farmers, millers, processing industries, dealers, seed companies, extension professionals, researchers and policy makers to share knowledge, experiences and ideas for a durum wheat value chain. The 10 best durum wheat lines are being evaluated in wheat trials across 9 locations right now.

CIMMYT representatives including Joshi will take part during 31 May-2 June in the international conference “From Seed to Pasta and Beyond: a Sustainable Durum Wheat Chain for Food Security and Healthy Lives,” with experts from around the world.

Australian visit to CIMMYT-Turkey strengthens decades-long collaboration

Written by on June 1, 2015. Posted in News.

The CIMMYT Australia ICARDA Germplasm Evaluation Project (CAIGE) organized a visit for Australian breeders to Turkey during 19 April-3 May. Participants learned about the germplasm evaluation and selection activities by the International Winter Wheat Improvement Program (IWWIP, a joint enterprise of CIMMYT and the Government of Turkey), the CIMMYT-Turkey Soil Borne Pathogen (SBP) program and the Regional Rust Research Center.

The CIMMYT-Turkey collaboration has helped farmers throughout Central and West Asia. It all began in 1965, when a farmer in southern Turkey planted a high-yielding variety from Mexico that yielded five tons per hectare– several times more than the Turkish varieties then being planted. Wheat varieties from Mexico and new agronomic practices allowed Turkey to double its wheat production in just a decade, marking the start of a Turkish “Green Revolution.”

Turkey has since become a leader in wheat research. Turkish scientists with IWWIP have led groundbreaking research on zinc deficiency in soils and developed varieties that not only perform well in such conditions but also contain enhanced levels of zinc in the grain. Turkey is also a focal point for collaborative research on the effect of soil-borne pathogens and pests on wheat, as well as developing resistant varieties.

The five Australian breeders experienced first-hand Turkey’s rich history and innovations in wheat research and development. The group first visited the Bahri Dagdas International Agricultural Research Institute-National Drought Center in Konya, where Mustafa Kan, Institute Director and IWWIP Coordinator, welcomed them and gave an overview of the Institute. Alexei Morgounov, IWWIP Leader, and Mesut Keser, ICARDA’s Office Coordinator in Turkey, also gave presentations. The group then visited the labs and greenhouse facilities, crown rot yield trials and IWWIP breeding programs.

The next day, the group visited the Transitional Zone Agricultural Research Institute in Eskisehir. Director Sabri Cakir gave an overview of the Institute, while Savas Pelin, Head of the Institute’s breeding program in Eskisehir, gave a general presentation of its programs and activities. Participants also attended an overview of SBP’s activities, including screening for nematodes and crown rot in growth rooms, greenhouses and fields.

On the third day, attendees visited the Agricultural Research Institute in Izmir and Turkey’s National Gene Bank. They were introduced to IWWIP’s breeding activities, including germplasm evaluation, synthetic winter wheat development, spring x winter crossing and soil borne pathogen screening. The group also visited the Regional Rust Research Center, led by ICARDA scientist Nazari Kumarzi, where they observed the stripe, leaf and stem rust evaluation nurseries and afterwards visited the national barley breeding program.

In Izmir, visitors reviewed the soil-borne pathogen research, screening methodologies and facilities at CIMMYT-Turkey. CAIGE Project Leader Richard Trethowan inspected the germplasm provided by Australia to CIMMYT-Turkey as part of the crown rot initiative, a sub-grant project with the University of Sydney funded through the Grains Research and Development Corporation (GRDC) aimed at transferring resistant genes into key elite varieties for rapid adoption by breeding programs. Visitors were also briefed about the intensive SBP-IWWIP collaboration, particularly on incorporating resistant sources into high-yielding winter and spring wheats.

The Australian breeders included Richard Trethowan, Professor at the University of Sydney; Daniel Mullan and David Moody, Wheat and Barley Breeders from Intergrain; Mark Dieters, Senior Lecturer at the University of Queensland and Ian Edwards, CEO of Edstar Genetics. CIMMYT participants included Alexei Morgounov, CIMMYT-Turkey Country Representative; Amer Dababat, Soil Borne Disease Pathologist and Gul Erginbas-Orakci, Senior Research Associate.

CSISA mechanization meets farmers’ needs in Bihar, India

Written by on June 1, 2015. Posted in Features.

“A huge bottleneck exists in terms of time wasted in harvesting and threshing that is preventing timely sowing of crops,” said Scott Justice, agriculture mechanization specialist, CIMMYT. The Cereal Systems Initiative for South Asia (CSISA) is working to ensure smallholder farmers have access to machinery based on their specific requirements by improving existing designs to meet local needs.”

For shelling maize, farmers in Bihar can either purchase a very large, efficient machine that costs approximately US $786 or use a cheap handheld sheller that can shell only 15-20 kilograms per hour. According to Justice, “these lightweight, affordable shellers are relatively new on the scene. Their simple design means that they can easily be made by local manufacturers and can also be modified as required.”

CSISA worked with a local manufacturer to modify the design of a medium-sized sheller and created a double cob maize sheller powered by an electric motor, which can shell 150 kg of maize per hour and consumes only 2-4 units of electricity. Priced at US $126, the machine is fairly affordable. “In fact, half the cost of the machine is that of the electric motor alone. For farmers who already own one, the machine would only cost US $63,” said Suryakanta Khandai, Postharvest Specialist at the International Rice Research Institute (IRRI), who works for CSISA in Bihar.

During a pilot program with members of the Kisan Sakhi Group in Muzzafarpur, Bihar, nearly 350 women farmers were trained to operate the diesel engine-powered, open-drum thresher. In this picture, Suryakanta Khandai (center), IRRI postharvest specialist, conducts a demonstration for two women’s self-help groups interested in purchasing four machines next season.

Until recently, farmers in Bihar only had two options for mechanized rice threshing –a very large axial flow thresher that can cost up to US $2,700 with subsidies, or a pedal-powered, open-drum thresher that has very low capacity and is difficult to operate for extended periods.

“Farmers clearly needed a medium-sized, affordable, efficient and portable mechanical rice thresher,” said Khandai. “The existing models lacked grain-separating or bagging functions, which we included in the new design. In addition to giving it wheels, we also decided to use a diesel engine to power the machine to allow for threshing in the field immediately upon cutting, which helps reduce losses.” The result was a diesel-powered, open-drum thresher.

It costs US $23.96 to hire one person to manually thresh one acre of rice and it takes seven days. However, the diesel-powered, open-drum thresher covers the same area in just over four hours, at a total cost of US $10.54.

Since the modified machines do not offer an attractive profit for larger manufacturers and retailers, CSISA approached local companies to fill the gap. The maize sheller was customized in cooperation with Dashmesh Engineering, which sells the machine at a profit of US $11–13. “Profits help ensure that the manufacturers are motivated to scale out the machines,” said Khandai.

Justice added, “Equipment like the diesel-powered, open-drum rice thresher is very simple but has not spread very widely. I feel these should now also be promoted to the owners of two-wheel tractors and mini tillers in India and Nepal.”

Well-positioned for next phase, CSISA India plans for monsoon cropping season

Written by on June 1, 2015. Posted in News.

As Phase II of the Cereal Systems Initiative for South Asia (CSISA) draws to a close in India, it is well positioned for a Phase III, according to Andrew McDonald, CIMMYT Cropping Systems Agronomist and CSISA Project Leader speaking at the Objective 1 planning and evaluation meeting for the 2015 monsoon cropping season held in Kathmandu, Nepal, on 22-24 April. The meeting was attended by CSISA’s Objective 1 teams from the Bihar, eastern Uttar Pradesh, Odisha and Tamil Nadu hubs, comprising diverse disciplinary experts from CIMMYT, the International Food Policy Research Institute (IFPRI), the International Livestock Research Institute (ILRI) and the International Rice Research Institute (IRRI).

Phase II began in October 2012 and will be completed in October of this year. The external evaluation report, commissioned by the United States Agency for International Development (USAID), commended the uniqueness of CSISA’s work with service providers and farmers, its staff’s dedication and the strong collaboration among CSISA partners. CSISA was established in 2009 to promote durable change at scale in South Asia’s cereal-based cropping systems, and operates rural “innovation hubs” throughout Bangladesh, India and Nepal.

The teams took a critical view of activities from the previous monsoon cropping season and highlighted priority areas for this year. “Sustainable intensification of cropping systems should be the centerpiece of our growth strategy. Rice followed by mustard followed by spring maize or green gram is a great system that can help us achieve 300% cropping intensity,” said R.K. Malik, CIMMYT Senior Agronomist and CSISA Objective 1 Leader. “We need to focus not only on how to create new service providers but also on how existing ones can be used as master trainers. This will help fill the gap of field technicians and further strengthen delivery,” Malik explained, regarding CSISA’s network of more than 1,800 service providers.

Leading discussions on the Odisha hub, Sudhir Yadav, IRRI Irrigated Systems Agronomist, emphasized the importance of identifying the non-negotiable steps for successful technology implementation. “The performance of zero tillage, for example, depends on soil type, date of seeding and whether the crop is rainfed or receives supplementary irrigation,” said Yadav. CSISA successfully introduced zero tillage in Odisha’s Mayurbhanj District, where it has enabled crop intensification thanks to the retention of residual soil moisture.

The meeting served as a platform for representatives from Catholic Relief Services’ (CRS) Improved Rice-based Rainfed Agricultural Systems project to showcase lessons in managing rainfed rice systems in northern Bihar.

CSISA is currently in discussions with USAID and the Bill & Melinda Gates Foundation (BMGF) to design the technical program, and determine the scope, geography, duration and budget of Phase III.

Maize protects Colombian coffee from climate change

Written by on June 1, 2015. Posted in News.

The Eddy Covariance microclimate station in Paraguaycito takes meteorological data needed to predict climate variability. Phots: Claudio Romero Perilla.

Preliminary results have shown that a maize-coffee cropping system acts like a huge atmospheric carbon sink, capturing up to 60 times more carbon than a coffee-bean system during one cycle of the associated temporary bean crop. In addition, maize creates a more adequate micro-climate for coffee’s growth and development because it reduces air temperature, helps to maintain soil moisture and decreases daytime-nighttime soil temperature fluctuations. This has a buffer effect that benefits soil biochemical processes and improves crop productivity.

To demonstrate advances of the project “Increasing the profitability of maize-coffee systems” that CIMMYT has been conducting in Colombia for 10 years in collaboration with the National Federation of Colombian Coffee Producers (FEDERECAFE, Spanish acronym), two field days were held at the Paraguaycito–Quindío (29 April) and La Catalina–Risaralda (7 May) Experiment Stations belonging to CENICAFE, FEDERECAFE’s research unit. At these events, attended by 158 representatives of the Local Coffee Growers’ Committees and the National Federation of Cereal Growers (FENALCE, Spanish acronym), the latest advances in the areas of climate change, agronomy and genetic improvement were presented.*

At Paraguaycito, CENICAFE agronomists Myriam Cañon and Angela Castaño explain the effects of climate on the coffee-maize system.

On the subject of climate change, Angela Castaño, a Ph.D. student at Cauca University linked to CENICAFE, indicated that at the Paraguaycito Experiment Station, the performance of agro-ecosystem depends on energy-water-carbon dynamics, because its distribution is related to the production system. In the case of coffee, solar radiation, water and atmospheric carbon are distributed differently depending on whether the coffee is fully exposed to the sun, or if it is grown in association with other crops.

With the aim of studying energy-water-carbon dynamics in different coffee production systems, at Paraguaycito there is an Eddy Covariance micro-climate station that measures the sun’s energy and the amount of carbon and water vapor in the production system. Strategically placed sensors in the micro-climate station measure air and soil temperature and humidity, as well as the flow of latent heat (energy used for evapotranspiration) and of perceivable heat (energy used to heat the air). This information is used to study four types of agro-ecosystems that include growing temporary crops during the growth stage of coffee, namely, coffee with maize; coffee with common beans; coffee with pigeon-pea; and coffee under full sun exposure.

Myriam Cañon, Paraguaycito Station Coordinator, mentioned that the coffee-maize association reduces the number of coffee plants that die.

Diego Montoya, La Catalina Station Coordinator, explained that rain is now less frequent but more intense. This causes damage due to surface runoff on the steep terrain where coffee is grown in Colombia. However, there is less damage when coffee is cropped in association with maize because the soil is better protected by both crops.

This is the first of a two-part report; the second part will be published in the next issue of the CIMMYT Informa.

AWARENESS-RAISING ON ISSUES AFFECTING AGRICULTURE, FOOD AND CULINARY ARTS

International Women’s Day on March 8, offers an opportunity to recognize the achievements of women worldwide. This year, CIMMYT asked readers to submit stories about women they admire for their selfless dedication to either maize or wheat. In the following story, Amanda Niode writes about her Super Woman of Maize, Asriani Anie Annisa Hasan of the Gorontalo Corn Information Center and Food Security Agency.

Asriani Anie Annisa Hasan is my maize superwoman.

Anie is a beautiful and warm-hearted woman, who is currently head of the Dissemination and Information Division at the Gorontalo Corn Information Center and Food Security Agency.

Gorontalo is a province located on the island of Sulawesi in Indonesia on the Wallacea, borderline islands situated between the Asian and Australian bio-geographical regions characterized by great biodiversity of flora and fauna.

Anie is not known as an official who works behind her desk. She is very much involved in the cornfields and the livelihoods of farmers, taking pictures of newly harvested cornfields, driving a truck, or sitting on the floor chatting with corn farmers.

She informs farmers about native corn varieties found in Gorontalo, including those on the brink of extinction such as momala, motorokiki, bonia/badia and pulut (binthe pulo).

Additionally, Anie is very active on social media networks and always explains her corn-related activities in a fun way, One of her Facebook posts features two decorated corn cobs saying: “Corns fall in love today. Love maize.”

In another post, she wrote: “Sunday morning is usually laundry time, but now I should be chummy with the corn field.”

She is always on the forefront on any major corn-related activity, including the International Maize Conference, which was held in Gorontalo in 2012, and attended by corn experts from all over the world.

She works very hard to assist the Omar Niode Foundation, an organization working to raise public awareness about issues affecting agriculture, food and culinary arts. This work included attending an exhibition of Gorontalo local corns in Jakarta, Indonesia’s capital.

Anie Annisa, is a passionate maize superwoman.

International Women’s Day on March 8, offers an opportunity to recognize the achievements of women worldwide. This year, CIMMYT asked readers to submit stories about women they admire for their selfless dedication to either maize or wheat. In the following story, Vivian Bernau writes about her Super Woman of Maize, Candice Gardner, a research leader with the U.S. Department of Agriculture.

Candice Gardner serves as research leader for the U.S. Department of Agriculture’s North Central Region Plant Introduction Station (USDA-ARS NCRPIS), one of the 20 gene banks of the U.S. National Plant Germplasm System, where she is responsible for overseeing both fiscal and operation management, as well as guiding the execution of research.

Dr. Gardner’s interests have guided her through several research positions. She worked in industry as a maize breeder and later as a technology trait developer, and now oversees two premier public maize research programs in the United States.

In her current role, Dr. Gardner chaperones both the conservation of the U.S. maize collection (including more than 20,000 accessions, held in a gene bank in Ames, Iowa) and the Germplasm Enhancement of Maize (GEM) project, a collaboration between USDA-ARS, and both public and private research scientists.

No one will deny that germplasm conservation is important for preserving genetic diversity, but in recent years research funding for the USDA-Agriculture Research Service has not necessarily kept up with the increase in demand for germplasm. Dr. Gardner has helped to guide the research station through many transitions and works as an advocate for all of the programs she oversees.

Additionally, while her expertise is in maize breeding and genetics, she has served as an excellent mentor to many students and young researchers who have worked at the research station – including me. Her passion for quality research to improve maize production and protect the world’s germplasm is inspiring to say the least.

PROMOTION, ADOPTION, AND EVALUATION OF HIGH PROTEIN CORN VARIETIES

International Women’s Day on March 8, offers an opportunity to recognize the achievements of women worldwide. This year, CIMMYT asked readers to submit stories about women they admire for their selfless dedication to either maize or wheat. In the following story, Haley Kirk writes about her Super Woman of Maize, Jennifer Brito, food security coordinator at Semilla Nueva.

As the Food Security Coordinator at Semilla Nueva, Jennifer Brito works with women in 10 coastal Guatemalan communities to improve the livelihoods, nutrition, and all-around well-being of their families.

Jen has been with Semilla Nueva, a non-governmental organization developing locally-led farmer education programs to alleviate poverty and boost food security, for almost a year and a half.

During that time, her work has involved promoting several varieties of quality protein maize (QPM) with families in our communities. High-yielding QPM, which was developed at the International Maize and Wheat Improvement Center (CIMMYT) in the 1990s, contains almost double the protein of other maize varieties grown in the tropics.

Additionally, Jen is leader of a study Semilla Nueva is undertaking an evaluation of the impact of QPM on malnutrition in Guatemala.

Jen has taught her participants how to make various recipes, including green tortillas, which use local herbs and QPM to transform the nutritionally empty tortilla into a vessel containing extra protein and vitamins.

To create “tortillas verdes” she worked with locally-grown, micronutrient-rich chaya, chipilín, and hierbamora leaves. She boiled a large amount of leaves and mixed the cooked leaves together with a nixtamal alkaline solution, which helps improve nutritional value. At the mill, the corn was combined with the herbs to create green corn dough.

Jen’s work with women in rural Guatemalan communities is key to the successful promotion, adoption, and evaluation of high protein corn varieties that could potentially lift Guatemala out of its position as the most malnourished country in the western hemisphere.

SUPER WOMAN: Chhavi Tiwari aids women farmers with zinc-fortified wheat

ZINC DEFICIENCY IS ATTRIBUTED TO 800,000 DEATHS EACH YEAR

International Women’s Day on March 8, offers an opportunity to recognize the achievements of women worldwide. This year, CIMMYT asked readers to submit stories about women they admire for their selfless dedication to either maize or wheat. In the following story, scientist Velu Govindan writes about his Super Woman of Wheat, Chhavi Tiwari, a senior research associate at Banaras Hindu University.

Zinc deficiency is attributed to 800,000 deaths each year and affects about one-third of the world’s population, according to the World Health Organization (WHO).

It can lead to short stature, hypogonadism, impaired immune function, skin disorders, cognitive dysfunction and anorexia. Additionally, it causes approximately 16 percent of lower respiratory tract infections, 18 percent of malaria cases and 10 percent of diarrheal disease cases worldwide, WHO statistics show.

Enhancing the micronutrient content in wheat through biofortification is increasingly seen as an important tool to help improve the livelihoods of the most vulnerable, poorest and least educated sectors of society.

That is why Dr. Chhavi Tiwari, senior research associate from Banaras Hindu University in Varanasi, India, is my super woman of wheat.

She has been working with the HarvestPlus program with active collaboration and support from the International Maize and Wheat Improvement Center (CIMMYT) to empower women farmers by making them aware of the value of micronutrient-rich wheat.

Her on-farm training programs increase their understanding of crop and soil management techniques, aiding in the improved production of wheat varieties high in zinc content.

Working closely with women’s self-help groups, she demonstrates the importance of wheat varieties high in zinc content through a participatory variety-selection approach, increasing the potential agronomic and nutritional benefit of these varieties for fast-track adoption.

Through her inclusive approach, a great deal of interest in high zinc wheat varieties has been generated among women farmers. Her efforts have contributed to the adoption of nutritious wheat varieties the eastern part of India’s state of Uttar Pradesh, leading to the potential for technology dissemination in neighboring states.

Engaging with rural women farmers is a core interest of Chhavi’s. She consults women farmers on their views and gives them the opportunity to participate in a decision-making process that increases their investment in agriculture and nutrition.

Her activities play a crucial role in uplifting women by alleviating malnutrition and hunger through nutritious wheat.

Chhavi is the recipient of the 2010 CIMMYT- Cereal System Initiative of South Asia (CSISA) research fellowship and the Jeanie Borlaug Laube Women in Triticum Award from the Borlaug Global Rust Initiative in 2014.

SUPER WOMAN: Julie King tames wild relatives of wheat, improving resilience

Written by on May 29, 2015. Posted in Features.

GENETIC VARIATION AND DIVERSITY TRANSFER ACROSS DIFFERENT GRASS SPECIES

International Women’s Day on March 8, offers an opportunity to recognize the achievements of women worldwide. This year, CIMMYT asked readers to submit stories about women they admire for their selfless dedication to either maize or wheat. In the following story, wheat breeder Jessica Rutkoski writes about her Super Woman of wheat, Julie King, a research fellow at Britain’s University of Nottingham.

Wild relatives of wheat are of particular importance to wheat breeders trying to develop disease-resistant and high-yielding varieties that can tolerate various environmental stresses, including drought and poor quality soils.

These wild grasses, cousins to the ancestors of modern-day wheat, provide a vast and largely untapped source of genetic variation for almost all traits important for wheat growers.

Plant geneticist Julie King, a research fellow with the University of Nottingham, has developed a new strategy for transferring genetic variation and diversity across different grass species. This strategy is now being used to transfer genetic variation into wheat from its distant relatives, which carry key disease resistance and stress tolerance genes. Very few people in the world are capable of this work, and so Julie plays a key role in adding new variations.

By crossing wheat with its wild relatives, a painstaking process, Julie and her research team aim to improve the ability of wheat to tolerate heat, drought, and salt – of key benefit in a world where freshwater is going to become even more scarce amid changing climate and population pressures.

Working with wild relatives is very difficult and not many people can do it – it’s like magic. It almost takes super powers to overcome the many barriers that can prevent hybridization of the species – so many crosses fail.

SUPER WOMAN: Evangelina Villegas developed transformative quality-protein maize

Written by on May 29, 2015. Posted in Features.

DIETARY DEPENDENCE ON MAIZE PUTS SOME PEOPLE AT RISK FOR MALNUTRITION

For International Women’s Day I would like to honor Dr. Evangelina Villegas, one of CIMMYT’s original “superwomen,” not only for the breakthroughs she made in her field, but for the positive impact she made on the world.

Villegas was born in Mexico City in 1924 and earned a Bachelor of Science degree in chemistry and biology at the National Polytechnic Institute at a time when higher education for women was still a novelty.

In 1950, she began her career as a chemist and researcher at Mexico’s National Institute of Nutrition and at the Special Studies Office, an initiative funded by the Rockefeller Foundation and the Mexican Secretary of Agriculture and Livestock (SAGARPA) that would later become the International Maize and Wheat Improvement Center (CIMMYT).

She returned to the center in 1967 after having earned a Master of Science degree in cereal technology from Kansas State University and a 1967 doctoral degree in cereal chemistry and breeding from North Dakota State University.

Villegas was both a maize and wheat superwoman, working in both the industrial wheat quality and maize nutritional and protein quality labs.

While in charge of the lab investigating protein quality she formed a fruitful partnership with Surinder Vasal, a CIMMYT maize breeder, in an attempt to develop a variety of maize with higher levels of two key amino acids.

A staple food in many developing countries, maize is deficient in the amino acids lysine and tryptophan, which are key protein building blocks. This means that people whose diets depend heavily on maize, without access to more varied food, are at risk for malnutrition.

After countless hours in the laboratory testing samples, sometimes up to 25,000 a year, their hard work culminated in the creation of quality protein maize (QPM). Grain of QPM features enhanced levels of lysine and tryptophan and the kernels have the texture and flavor that consumers like.

As an ingredient in pig and poultry feeds, QPM has been shown to enhance animal growth and health. QPM has shown to be particularly effective in improving the nutritional status of young children.

A 2002 study in Ethiopia found that children fed a QPM diet had a 15 percent increase in the rate of weight growth over those who consumed conventional maize, and a 2005 study found that QPM consumption in children led to a growth rate in height 15 percent greater than children fed conventional maize. Villegas and Vasal thus created a product that offers better nutrition for millions of consumers.

They received the World Food Prize in 2000 for their work developing QPM, making Villegas the first woman to receive the prestigious award. She was also named “Woman of the Year” in Mexico that year for her accomplishments.

In addition to her work improving lives and livelihoods around the world, Villegas changed the lives of many local “bird boys,” young men hired by CIMMYT to prevent birds from eating experimental crops, by helping to create a scholarship fund that allowed many of them to complete their education and go on to accomplish great things.

Without “Eva,” the world would be a hungrier and poorer place, and her hard work and dedication should be remembered by all.

SUPER WOMAN: Paula Kantor engages men to support gender progress

Written by Mike Listman on May 29, 2015. Posted in Features.

FOCUS ON WOMEN CAN INADVERTENTLY END UP ALIENATING MEN

Gender research and outreach should engage men more effectively, according to Paula Kantor, CIMMYT gender and development specialist who is leading an ambitious new project to empower and improve the livelihoods of women, men and youth in wheat-growing areas of Afghanistan, Ethiopia and Pakistan.

“Farming takes place in socially complex environments, involving individual women and men who are embedded in households, local culture and communities, and value chains — all of which are colored by expectations of women’s and men’s appropriate behaviors,” said Kantor.

“We tend to focus on women in our work and can inadvertently end up alienating men, when they could be supporters if we explained what we’re doing and that, in the end, the aim is for everyone to progress and benefit.”

Funded by Germany’s Federal Ministry for Economic Cooperation and Development, the new project will include 14 village case studies across the three countries. It is part of a global initiative involving 13 CGIAR research programs (CRPs), including the CIMMYT-led WHEAT and MAIZE.

Participants in the global project will carry out 140 case studies in 29 countries; WHEAT and MAIZE together will conduct 70 studies in 13 countries.

Kantor and Lone Badstue, strategic leader for gender research at the International Maize and Wheat Improvement Center, are members of the executive committee coordinating the global initiative, along with Gordon Prain of CIP-led Roots, Tubers and Bananas Program, and Amare Tegbaru of the IITA-led Program on Integrated Systems for the Humid Tropics.

“The cross-CRP gender research initiative is of unprecedented scope,” said Kantor. “For WHEAT, CIMMYT, and partners, understanding more clearly how gendered expectations affect agricultural innovation outcomes and opportunities can give all of our research more ‘ooomph’, helping social and biophysical scientists to work together better to design and conduct socially and technically robust agricultural R4D, and in the end achieve greater adoption and impact.”

To that end, outcomes will include joint interpretation of results with CRP colleagues and national stakeholders, scientific papers, policy engagement and guidelines for integrating gender in wheat research-for-development, according to Kantor.

Another, longer-term goal is to question and unlock gender constraints to agricultural innovation, in partnership with communities. Kantor said that male migration and urbanization are driving fundamental, global changes in gender dynamics, but institutional structures and policies must keep pace.

“The increase in de facto female-headed households in South Asia, for example, would imply that there are more opportunities for women in agriculture,” she explained, “but there is resistance, and particularly from institutions like extension services and banks which have not evolved in ways that support and foster the empowerment of those women.”

Kantor has more than 15 years of experience in research on gender relations and empowerment in economic development, microcredit, rural and urban livelihoods, and informal labor markets, often in challenging settings. She served four years as Director and Manager of the gender and livelihoods research portfolios at the Afghanistan Research and Evaluation Unit (AREU) in Kabul.

In the following story, Linda McCandless writes about her Super Woman of Wheat, Jeanie Borlaug Laube, chair of the Borlaug Global Rust Initiative.

Jeanie Borlaug Laube has served as the chair of the Borlaug Global Rust Initiative (BGRI) since 2009, a year after it was first launched.

She is an enthusiastic proponent of wheat research and enjoins all scientists to “take it to the farmer.”

She has helped build a community of wheat researchers and amplified their collective voice among politicians, policymakers, farmers, scientists and donors.

She is an influential advocate for wheat research and science. To mark the 100th anniversary of her father Norman Borlaug’s birth, in 2013 and 2014 she visited Ethiopia, Kenya, India, Pakistan, Turkey, Mexico, Washington, D.C, and Minnesota, speaking at various political events as an ambassador for wheat, food security, and global cooperation. Additionally, she met with scientists, farmers and other leaders.

The late Borlaug, known as “the father of the Green Revolution” for the high-yielding, disease-resistant, semi-dwarf wheat varieties he developed, won the Nobel Peace Prize in 1970.

In 2009, she initiated the Jeanie Borlaug Laube Women in Triticum Award for young career scientists, and there are now 25 awardees who are changing the face of wheat research.

In 2010, she initiated the Jeanie Borlaug Laube Mentor Award for those scientists, male or female, who are valuable mentors of young wheat scientists.

For her enthusiastic, persistent and persuasive advocacy of wheat as one of the most important crops for global food security, I nominate Jeanie Borlaug Laube as a Wheat Super Woman.

Morris dedicated her life and career to understanding and developing wheat genes.

Super woman: Rosalind Morris an “outstanding wheat cytogeneticist”

Written by on May 29, 2015. Posted in News.

Rosalind Morris was a pioneer in agricultural science at a time when there were very few women scientists. Her achievements were groundbreaking: in 1947, Morris and Leona O. Schnell became the first women to graduate with doctoral degrees from Cornell University’s department of plant breeding.

That same year, Morris became the first female faculty member hired in the agronomy department at the University of Nebraska at Lincoln (UNL). Later, in 1963, she became the first woman honored as a fellow of the American Society of Agronomy.

“Morris became an outstanding wheat cytogeneticist. She was a mentor to many wheat scientists, and a meticulous teacher,” said Thomas Payne, head of the Wheat Germplasm Bank at the International Maize and Wheat Improvement Center (CIMMYT).

Born in Wales in 1920, Morris had the unique opportunity to study agricultural sciences at a time when most college-age males were involved in World War Two. She earned her Bachelor of Science in Agriculture from the University of Guelph and was soon accepted into the graduate program in the plant breeding department at Cornell University.

During her career, Morris taught graduate courses in plant genetics and cytogenetics, exploring cell function and structure with a particular emphasis on chromosomes. She also became a junior partner in experiments to test the effects of X-rays and thermal neutrons on crop plants, studies, which are said to have grown out of concern over the effects of atomic bombs dropped on Hiroshima and Nagasaki during World War Two.

Morris succeeded in developing wheat genetic stocks, or wheat populations generated for genetic studies, that have worldwide importance in explaining wheat genetics. Her work provides a premier resource base for the emerging field of functional genomics, which explores how DNA is translated into complex information in a cell.

Though Morris is now retired, she often feels “homesick” for her work, according to an interview with the Agricultural Institute of Canada, a sign of the passion which truly makes her a super woman.

SUPER WOMAN: Nobel winner Barbara McClintock discovered “jumping genes”

Written by on May 29, 2015. Posted in Features.

“JUMPING GENES” EXPLAIN HOW BACTERIA BUILD UP RESISTANCE TO ANTIBIOTIC

At a time when women scientists were few and far between, Barbara McClintock made a name for herself as the most distinguished cytogeneticist in the field of science. From her early studies in genetics in the 1920s, to her 1940s breakthrough in mobile genetic elements, which led to her 1983 Nobel Prize, her legacy is one that still lingers today.

“She was a pioneer in agricultural sciences at a time when women scientists were not promoted or supported,” said Thomas Payne, head of the Wheat Germplasm Bank at the International Maize and Wheat Improvement Center (CIMMYT).

“Her contribution to cytogenetics, which explored cell function and structure with particular emphasis on chromosomes, was immense.”

Her work was groundbreaking. During the 1940s and 1950s, she discovered transposable elements and used them to demonstrate that genes are responsible for determining physical characteristics. Later, she made an extensive study of the cytogenetics and ethnobotany of South American maize races.

McClintock’s theories on transposition were initially met with skepticism. In 1950, when she first reported that genetic information could transpose from one chromosome to another, mainstream scientists assumed that her discoveries were not universally applicable to all organisms.

It wasn’t until the 1960s, when biologists Francois Jacob and Jacques Monod discovered similar controlling elements in bacteria that the importance of her research was realized. McClintock received the Nobel Prize in Physiology or Medicine in 1983, and to this day remains the only woman to receive an unshared Nobel Prize in that category.

Born in Hartford, Connecticut, in 1902, McClintock began her studies at Cornell’s College of Agriculture in 1919, attending the only genetics course open to undergraduate students in 1922. She received her Ph.D in botany in 1927, thus beginning her career as leader in the development of maize cytogenics.

By the time of her death in 1992, it was widely recognized that McClintock’s work had greatly assisted in the understanding of human disease. “Jumping genes” help explain how bacteria are able to build up resistance to an antibiotic, and there is some indication that these genes are involved in the alteration of normal cells to cancerous cells.
As a pioneer in agricultural sciences, McClintock truly was a superwoman.
