Written by Julian Bañuelos-Uribe on May 11, 2023. Posted in Press releases.

AMES, IOWA—The Council for Agricultural Science and Technology (CAST) has announced the 2023 Borlaug CAST Communication Award goes to Alison Bentley.

While Bentley is known for her global research on wheat genetics, she is also recognized for her proficiency in science communication. Bentley has a passion for delivering practical applications from innovation to farmers, extensive reach through communicating and influencing, and mentoring and support of individuals and community efforts. Bentley’s exceptional work in raising awareness about the importance of wheat as a food crop is also evidenced by her wide-ranging list of communication activities.

In 2022 alone, Bentley delivered 20 scientific presentations—including five international keynote talks and 15 additional invited talks. Bentley focused her communication efforts around two major areas. The first area was her rapid, science-led response to the impact of the Russian/Ukraine war on global wheat production through a communication article in Nature, followed with a social media campaign and numerous presentations and invited policy briefings. Her second area of focus was a major communications campaign by initiating and leading the Women in Crop Science network. This network was developed to address key issues such as the promotion and championing of females throughout their research careers, creating equal opportunities, and increasing visibility of members.

The extensive breadth of Bentley’s outreach ranges from classic science presentations and open access articles to blogs, podcasts, YouTube videos, and Twitter campaigns. All these formats demonstrate her commitment to science communication and reaching as wide an audience as possible in an accessible way to engage with important, current topics regarding wheat supplies and plant breeding.

The official presentation of the award will take place at a special side event during the World Food Prize Borlaug Dialogue event in Des Moines, Iowa, in October. The Borlaug CAST Communication Award honors the legacy of Norman Borlaug, a Nobel Prize winner and author of the first CAST publication, and Dr. Charles A. Black, the first executive vice president of CAST. It is presented annually for outstanding achievement by a scientist, engineer, technologist, or other professional working in the agricultural, environmental, or food sectors for contributing to the advancement of science through communication in the public policy arena.

As part of its crucial mission to accelerate wheat adaptation to rapidly changing climate conditions due to global warming, the Heat and Drought Wheat Improvement Consortium (HeDWIC) with the support of the Foundation for Food & Agriculture Research (FFAR) has granted 10 awards since 2021, crowdsourcing innovative research from around the world.

Like other crops, wheat – which makes up 20 percent of the human diet – is affected by threats to the global food system from persistent population growth and economic and climate pressures. These challenges are further exacerbated by the fallout from the COVID-19 pandemic and the war in Ukraine. There is an urgent need to prioritize climate resilient wheat varieties to protect this food staple.

Some five years after HeDWIC was launched in 2014 to incorporate the most advanced research technologies into improving heat and drought tolerance of wheat, the Intergovernmental Panel on Climate Change reported that climate change was having an impact on food security through increasing temperatures, changing precipitation patterns and greater frequency of extreme weather events in its Special Report on Climate Change and Land.

“While some areas are becoming more conducive to wheat growing, crop yields are suffering in other regions around the world traditionally known as bread baskets,” said wheat physiologist Matthew Reynolds, who leads HeDWIC at the International Maize and Wheat Improvement Center (CIMMYT).

“Wheat is one of our fundamental crops, and we must spare no effort in protecting it from current and future challenges,” said Saharah Moon Chapotin, FFAR executive director. “Global collaborations are necessary to address global concerns, and these grants are bringing together international teams to share and build the science and research that will ensure the stability of this crop.”

The 10 recipient projects are under the umbrella of the HeDWIC project Harnessing Translational Research Across a Global Wheat Improvement Network for Climate Resilience, funded by FFAR. The first five awardee projects were identified in 2021, and an additional five projects were awarded in 2022.

To boost new ideas in “climate-proofing” crops, HeDWIC conducts virtual meetings that include all awarded research teams to take advantage of the collective global expertise in heat and drought resilience, leading to cross-pollination of ideas and further leverage of resources and capabilities.

In March, Reynolds led in-person discussions with some of the collaborating researchers at CIMMYT’s experimental research station on the outskirts of Ciudad Obregon, a city in Mexico’s Sonoran Desert, during CIMMYT’s annual Visitors’ Week.

Projects awarded in 2022

Exploring the potential of chlorophyll fluorescence for the early detection of drought and heat stress in wheat (FluoSense4Wheat)

“The HeDWIC mini proposal allows us to explore the potential of chlorophyll fluorescence for the early detection of drought and heat stress in wheat. The controlled irrigation conditions for wheat grown in Obregon give us the opportunity to quantify photosynthesis by fluorescence while drought develops. Detecting a drought-specific fluorescence response and/or the interaction between active and passive fluorescence is relevant for breeding selecting purposes as well as large spatial scale detection of drought by monitoring the plant.” – Onno Muller, Forschungszentrum Jülich, Institute of Bio- and Geosciences, Germany

Physiological basis of amelioration of heat stress through nitrogen management in wheat

“Heat stress during grain filling can restrict the availability of carbohydrates needed for grain development. India has been experiencing sudden spikes in both minimum and maximum temperatures by 3 to 5 degrees above normal from late-February onwards, which is an important time for wheat grain-filling and has resulted in declining wheat productivity. Our team is examining the ability of pre-flowering nitrogen applications to support biomass accumulation and overcome the grain-filling source (carbohydrate) limitation during heat spikes. If successful, the results could have broad-reaching benefits given that farmers are familiar with and well-skilled in using nitrogen applications regimes in crop management.” – Renu Pandey, Division of Plant Physiology, Indian Agricultural Research Institute

Can reproductive development be protected from heat stress by the trehalose 6-phosphate pathway?

“The HeDWIC funding provides a unique opportunity to test how the regulatory sugar, trehalose 6-phosphate (T6P) can protect wheat yields against increasingly common chronic and acute heat stress events. We have already shown that T6P spray increases wheat yields significantly in field conditions under a range of rainfall in wet and dry years. With increasing likelihood of heat stress events in the years ahead, in unique facilities at CIMMYT, we will test the potential of T6P to protect reproductive development from catastrophic yield loss due to chronic and acute heat.” – Matthew Paul, Rothamsted Research, UK

Investigating tolerance of heat resilient wheat germplasm to drought

“Over the last decade, we have developed heat tolerant wheat germplasm at the University of Sydney that maintains yield under terminal heat stress. In our new HeDWIC project, this material will be tested under combined drought and heat stress under field conditions. This will provide plant breeders with highly valuable information on field tested germplasm for use in accelerated breeding programs targeting combined heat and drought tolerance. The work is critical for future food security considering the inextricable link between temperature and plant water demand, and the increased frequency and intensity of heat and drought events under projected climate change.” – William Salter, University of Sydney, Australia

Novel wheat architecture alleles to optimize biomass under drought

“Wheat Rht-1 dwarfing genes were an essential component that led to spectacular increases in grain yields during the Green Revolution. Although Rht1 and Rht2 are still used widely in wheat breeding 50 years after they were introduced, they are suboptimal under drought conditions and are often associated with a yield penalty. Using a more extensive range of Rht-1 dwarfing alleles that were developed at Rothamsted, we will introduce them into CIMMYT germplasm to optimize biomass and ultimately increase grain yields under drought stress.” – Steve Thomas, Rothamsted Research, UK

Additional comments from 2021 awardees

“This opportunity has enabled the collection of significant amounts of data that will contribute to the advancement of knowledge in crop physiology and root biology. It has also provided early career researchers with opportunities to gain hands-on experience, develop important skills, and grow their networks. Additionally, this initiative has stimulated further ideas and collaborations among researchers, fostering a culture of innovation and cooperation that is essential for progress.” – Hannah Schneider, Wageningen University & Research, Netherlands

“The project is a unique opportunity for research groups from around the world to coordinate efforts on identifying ways to improve heat tolerance of wheat.” – Owen Atkin, Australian National University, Australia

“It is important to understand how high temperature limits crop growth and yield and to identify genetic variation that can be used for breeding climate resilient crops. This project has already begun to develop new methods for rapidly screening growth and physiological processes in genetically diverse panels which we hope will be invaluable to researchers and breeders.” – Erik Murchie, University of Nottingham, UK

“This project will provide novel phenotyping screens and germplasm to breeders and lay the groundwork for genetic analysis and marker development.” – John Foulkes, University of Nottingham, UK

Wheat Disease Early Warning Advisory System (DEWAS)

Written by Sarah McLaughlin on March 10, 2023. Posted in Uncategorized.

The Wheat Disease Early Warning Advisory System (Wheat DEWAS) project is bringing new analytic and knowledge systems capacity to one of the world’s largest and most advanced crop pathogen surveillance systems. With Wheat DEWAS, researchers are building an open and scalable system capable of preventing disease outbreaks from novel pathogen strains that threaten wheat productivity in food vulnerable areas of East Africa and South Asia.

The system builds from capabilities developed previously by multi-institutional research teams funded through long-term investments in rust pathogen surveillance, modelling, and diagnostics. Once fully operationalized, the project aims to provide near-real-time, model-based risk forecasts for governments. The result: accurate, timely and actionable advice for farmers to respond proactively to migrating wheat diseases.

The Challenge

Farmers growing wheat face pathogen pressures from a range of sources. Two of the most damaging are the fungal diseases known as rust and blast. Rust is a chronic issue for farmers in all parts of the world. A study in 2015 estimated that the three rust diseases — stem, stripe and leaf — destroyed more than 15 million tons of wheat at a cost of nearly $3 billion worldwide. Wheat blast is an increasing threat to wheat production and has been detected in both Bangladesh and Zambia. Each of these diseases can destroy entire harvests without warning, wiping out critical income and food security for resource-poor farmers in vulnerable areas.

The Response

Weather forecasts and early-warning alerts are modern technologies that people rely on for actionable information in the case of severe weather. Now imagine a system that lets farmers know in advance when dangerous conditions will threaten their crop in the field. Wheat DEWAS aims to do just that through a scalable, integrated, and sustainable global surveillance and monitoring system for wheat.

Wheat DEWAS brings together research expertise from 23 research and academic organizations from sub-Saharan Africa, South Asia, Europe, the United States and Mexico.

Together, the researchers are focused on six interlinked work packages:

Work package	Lead	Objectives
Data Management	Aarhus University; Global Rust Reference Center	Maintain, strengthen and expand the functionality of the existing Wheat Rust Toolbox data management system Create new modules within the Toolbox to include wheat blast and relevant wheat host information Consolidate and integrate datasets from all the participating wheat rust diagnostic labs Develop an API for the two-way exchange of data between the Toolbox and the Delphi data stack Develop an API for direct access to quality-controlled surveillance data as inputs for forecast models Ensure fair access to data
Epidemiological Models	Cambridge University	Maintain operational deployment and extend geographical range Productionalize code for long-term sustainability Multiple input sources (expert, crowd, media) Continue model validation Ensure flexibility for management scenario testing Extend framework for wheat blast
Surveillance (host + pathogen)	CIMMYT	Undertake near-real-time, standardized surveys and sampling in the target regions Expand the coverage and frequency of field surveillance Implement fully electronic field surveillance that permits near real-time data gathering Target surveillance and diagnostic sampling to validate model predictions Map vulnerability of the host landscape
Diagnostics	John Innes Centre	Strengthen existing diagnostic network in target regions & track changes & movement Develop & integrate new diagnostic methodology for wheat rusts & blast Align national diagnostic results to provide a regional & global context Enhance national capacity for wheat rust & blast diagnostics

Pravasi Bharatiya Samman winner, scientist Dr Ravi Singh is working towards food security for all

Written by Sarah McLaughlin on January 25, 2023. Posted in In the media.

As he retires from his illustrious career, a new interview with Ravi Singh, Head of Global Wheat Improvement at CIMMYT, by the Global Indian reveals his motivations for becoming a scientist and his desire to ensure people all over the world had access to food.

“I retired quite recently, however, I have a lot to do. I wish to mentor young scientists about on how to increase food production. I also look forward to working on several high-profile projects with farmers to tackle future issues they might face due to the climate changes on a crop like wheat,” shares the scientist.

Singh was honored with the Pravasi Bharatiya Samman by the Government of India in January 2021, recognizing his outstanding achievements by non-resident Indians, persons of Indian origin, or organizations or institutions run by them either in India or abroad. He received this for his role in the development, release, and cultivation of more than 550 wheat varieties over the past three decades.

Singh has also been included among the top one percent of highly-cited researchers, according to Clarivate Analytics-Web of Science every year since 2017.

How a new generation of women are changing wheat science

Written by Sarah McLaughlin on January 19, 2023. Posted in News.

by Krisy Gashler 

For Charlotte Rambla, winning the 2022 Jeanie Borlaug Laube Women in Triticum (WIT) Early-Career Award was an “incredible, unreal experience.”

Each year, the Borlaug Global Rust Initiative (BGRI) honors five to six female early-career wheat researchers with the WIT award in recognition of scientific excellence and leadership potential. With the award, women scientists receive leadership training and professional development opportunities meant to support them as they join the community of scholars who are fighting hunger worldwide.

“The training I’ve received with this award has been one of the best experiences of my professional life,” said Rambla, an Italian native who recently completed her Ph.D. at the Queensland Alliance for Agriculture and Food Innovation in Australia and has begun a postdoctoral appointment at the Salk Institute for Biological Studies. “Meeting these incredible women working in the same field, sharing our knowledge and experiences, it felt like we belonged together and were working toward one shared purpose; We are all joined by this same passion for agriculture and science.”

The 2022 awards honored six early-career scientists from Morocco, Indonesia, Ethiopia, Italy, Pakistan and China. Since 2010, the WIT awards have recognized 66 early-career scientists from 29 different countries. The training and development opportunities offered to each year’s cohort varies, based on the needs and interests of the winners, said Maricelis Acevedo, director for science for the BGRI, research professor in the Department of Global Development at Cornell University, and a 2010 WIT awardee. The 2022 WIT cohort visited the World Food Prize Foundation in October, just before the foundation announced the winner of this year’s World Food Prize, widely considered the Nobel Prize for food and agriculture.

“The role of the WIT award is to recognize emerging scientific leadership and provide training and support for women working in wheat to create a cohesive group of hunger-fighters who have the skills to lead the next generation of scientists and create the solutions that we need at such a critical time,” Acevedo said. “As these women receive the award, we hope that they continue to support other women and other early-career scientists, and to train their students in a more open, diverse network.”

Meriem Aoun, a 2018 WIT awardee and native of Tunisia, was a postdoctoral associate at Cornell University when she won her award. Her cohort received a month-long training at the International Maize and Wheat Improvement Center (CIMMYT) – the center where Norman Borlaug did the research that earned him the 1970 Nobel Peace Prize – and attended the 2018 international BGRI conference in Morocco. Aoun believes that the WIT award supported her professional career development and gave her the opportunity to connect with other WIT winners from many countries. “I am thrilled to see more and more ambitious and career-interested wheat scientists and that our community of WIT winners is growing each year,” she said.

Now an assistant professor of wheat pathology at Oklahoma State University (OSU), Aoun studies the genetics of disease resistance to wheat pathogens. She is a key member of OSU’s wheat improvement team developing disease-resistant wheat varieties suited for Oklahoma and the Southern Great Plains of the U.S.

For 2013 winner and Swiss-Argentinian Sandra Dunckel, the fact that BGRI chooses a cohort of women each year, rather than a single winner, is one of the strengths of the award. Now head of Breeding Barley, Special Crops and Organics at KWS Group, a multinational seed company headquartered in Germany, Dunckel said the networking opportunities were among the most beneficial aspects of her WIT award training.

“There is this group of women who are working on a common goal, and even if you aren’t in touch for several years, you can contact someone from your year, or really any year, and say, ‘Hello, fellow WIT winner, I’m looking for a breeder with great potential for one of my teams, can you recommend someone, or I need help with this question.’ It’s always there to fall back on,” she said.

Dunckel won her WIT award while completing her PhD at Kansas State, then worked for two years as a wheat breeder in Australia before moving to her current role at KWS, where she oversees nine breeding teams across Europe who are working to develop new barley, peas, oats and protein crop varieties that are more tolerant to drought and heat, have desired quality profiles and can be grown more sustainably globally.

Paula Silva, a 2020 WIT awardee, also won her award while completing her PhD at Kansas State. She has since returned to her native Uruguay, where she leads the breeding team developing disease resistant varieties of barley and wheat for Uruguay’s National Institute of Agricultural Research (INIA). From 2019-2022, she coordinated breeding efforts with CIMMYT by leading the Precision field-based Phenotyping Platform (PWPP) for Multiple Resistance to Wheat Diseases.

One of the purposes of the WIT award is to help achieve gender parity among wheat scientists, and Silva said she believes the award “is playing a big part in building gender equality.”

Silva said that as a student, she was encouraged to apply for the WIT award by Sarah Evanega, who, along with Ronnie Coffman, international professor emeritus of plant breeding and genetics at Cornell, lobbied for the establishment of the WIT award. The BGRI now annually presents WIT honors to early-career scientists and a mentor award for excellence in advising of women working in wheat and its nearest relatives.

“Sarah was always advocating for young, female participation,” Silva said. “I remember her counting how many females there were in conference pictures, and I do that now, too. You can see, year by year, the female representation gets bigger and bigger.”

Full gender equality in science is still lacking, but progress is being made. The gains are seen in wider perspectives that challenge orthodoxy and improve scientific possibilities.

“The WIT awards are a fantastic way to recognize and support emerging leaders in our community. The impressive cohort of past and present WIT recipients are actively contributing to global efforts to improve crop production and food security,” said Alison Bentley, who now leads the Global Wheat Program at CIMMYT.

Part of Acevedo’s leadership role for BGRI is helping choose each year’s winner, as part of a panel that includes previous WIT awardees and globally recognized wheat scientists, and working with each cohort to develop appropriate training opportunities. Acevedo said as she progressed in her career, she realized how important it was to help young female scientists not only with traditional training and networking opportunities, but also with leadership, communication, and work-life balance.

“It’s really tough to be an isolated scientist: science can be very individualistic. It can be competitive. As women in science, we feel particularly isolated because a lot of our colleagues are males. So you may feel like, ‘This is only happening to me, I’m the only one struggling with this,’” Acevedo said. “In these trainings, we celebrate professional and personal successes but also share our challenges, normalize struggles, and find support. As we think about a more collaborative and open science, we need to be talking more about humbleness, the positive impact of recognizing and making peace with weakness, and seeking support from one another to thrive as a diverse research community.”

The negative effects of climate change on food systems are felt across political boundaries, so creating sustainable remediation steps are best accomplished through global collaboration. In that spirit, the International Maize and Wheat Improvement Center (CIMMYT) and the Chinese Academy of Agricultural Sciences (CAAS) convened the China-CIMMYT Workshop on Climate Change & Food Crops Production on December 6, 2022.

Participants included principal investigators of China’s National Key Technology Research and Development Program, representatives of Chinese agricultural universities, CIMMYT scientists and representatives from a variety of international organizations. The agenda featured discussions regarding research priorities, efforts to establish best practices in classifying and prioritizing climate risks and identifying potential crucial points for future cooperation between CIMMYT and China.

After the welcome address from Wheat Breeder and Country Representative for China Zhongzhu He, Thomas Lumpkin, CIMMYT Director General Emeritus provided the introduction to global climate issues and their effects on agriculture, particularly staple crops like wheat.

“All climate change mitigation strategies must account for their effect on food production systems, the aim of this convening was to facilitate discussions among climate change scientists, crop breeders and agronomists,” said Lumpkin. “Global issues require global solutions and so collaboration among institutions is pivotal.”

Tek Sapkota, CIMMYT Agricultural Systems and Climate Change Scientist, presented a framework for quantifying GHG emissions and mitigation potential for food systems, key research objectives of the One CGIAR initiative MITIGATE+, an initiative aimed to reduce annual global food systems emissions by 7% by 2030.

Three other CIMMYT scientists presented at the workshop. Wei Xiong, Senior Scientist, Crop Modeler, focused on genotype-environment interactions and its implication on breeding. Urs Schulthess, Remote Sensing Scientist, presented state-of-the-art results on the effects of temperature and vapor pressure deficit on radiation use efficiency of wheat. Huihui Li, Scientist, Quantitative Geneticist, discussed expanding genome wide association mapping and genomic selection to include climatic factors, highlighting novel methods to bring genes and climate together to accelerate breeding cycles.

In the workshop’s closing remarks, Wei reiterated CIMMYT’s commitments to continued collaboration with Chinese institutions and outlined next steps, such as CIMMYT’s commitment to increasing global agricultural resilience via novel research, partnerships, and increased engagement. Wei also detailed methods to identify new mechanisms and funding channels to promote global cooperation, such as One CGIAR initiatives and funding from national partners, including the CAAS.

Exotic wheat DNA helps breed ‘climate-proof’ crops

Written by Sarah McLaughlin on January 16, 2023. Posted in In the media.

A new study has determined that wheat with exotic DNA from wild relatives benefits from up to 50 percent higher yields in hot weather, compared with elite lacks lacking these genes.

The study by the International Maize and Wheat Improvement Center (CIMMYT) and the Earlham Institute examined how exotic alleles contribute to wheat heat tolerance in different field conditions based on field trials in Sonora, Mexico.

“Crossing elite lines with exotic material has its challenges,” said Matthew Reynolds, co-author of the study and leader of Wheat Physiology at CIMMYT. “There’s a well-recognized risk of bringing in more undesirable than desirable traits, so this result represents a significant breakthrough in overcoming that barrier and the continued utilization of genetic resources to boost climate resilience.”

These results can be used to improve crop resilience and food security in the face of the challenges posed by climate change, as well as emphasizing the importance of genetic diversity in key crops where selective breeding has reduced adaptability.

From November 14 to 18, the International Maize and Wheat Improvement Center (CIMMYT) and the Alliance of Bioversity International and CIAT hosted the third workshop of the Community of Practice for Latin America and the Caribbean on the use of genomic and digital tools for the conservation and use of Genetic Resources for Food and Agriculture (GRAA).

The workshop, attended by 33 participants from 14 countries, was held at CIMMYT headquarters and highlighted topics such as the analysis of genotypic data derived from the DArTseq platform and the analysis of gaps in germplasm collections.

“It was very gratifying to be able to form this Latin American network of germplasm banks together with our colleagues from the Alliance of Bioversity International and CIAT,”said Carolina Sansaloni, Wheat Germplasm Bank Curator & Genotyping Specialist. “Training and knowledge exchange among germplasm banks is essential for better conservation, exploration and utilization of genetic resources in each country.”

Some of the participants shared the following comments and feedback:

“Excellent initiative, it is a fundamental support for the strengthening of plant genetic resources conservation systems and the creation of international collaborative networks. Thanks to CIMMYT and the Alliance of Bioversity International and CIAT for the invitation.” Mexico’s National Institute for Forestry, Agriculture and Livestock Research (INIFAP)
“Excellent workshop, a very important space for the exchange of knowledge and experiences, it also allows the formation of collaborative work networks between institutions and professionals from different countries with related research.” Escuela de Ciencias Agrarias, Universidad Nacional Costa Rica
“This workshop has allowed me to get in contact with colleagues from Latin America and to open the possibility of working together to advance in the characterization and contribute to the conservation of the collections we manage.” Instituto Nacional de Tecnología Agropecuaria, Argentina
“This has been a very profitable week for me as curator of the germplasm bank in Brazil. I learnt new concepts and tools that will generate advances in my work.” Brazilian Agricultural Research Corporation (EMBRAPA)

This workshop would not have been possible without the support of the CGIAR’s Genebank Initiative, DivSeek International and Analitek-Illumina.

Participatory action research identifies solutions for improved seed storage in Bangladesh

Written by Sarah McLaughlin on December 6, 2022. Posted in Publications.

Traditional and alternative seed storage methods have been compared in a participatory household trial co-designed by the International Maize and Wheat Improvement Center (CIMMYT) and smallholder farmers in Bangladesh, demonstrating how farmers can be involved in agricultural research.

In the summer monsoon season preceding planting in the winter, farmers typically use low-density polyethylene (LDPE) bags contained within woven polypropylene bags to store their wheat seed. Seed quality typically deteriorates over the monsoon as a result of increased seed moisture and pests that are associated with high humidity and temperature.

After initially being consulted by survey and detailed focus group interactions on the design of the trial, 80 wheat farming households participated in a 30-week action research process by conducting trials to compare seed storage methods. This included comparing hermetic SuperGrainbags® (Premium RZ) against LDPE bags, both with and without the addition of dried neem tree leaves (Azadirachta indica), the latter representing a common method used by farmers in Bangladesh to improved stored seed.

Results of the trials demonstrated that seed germination and seedling coleoptile length were greater, and that seed moisture was maintained at levels close to before storage in SuperGrainbags® compared to LDPE bags. The use of neem however had no effect on these factors.

Furthermore, hermetic bags were more effective in lessening seed damage caused during the storage process, but neem slightly reduced damage rates for seeds stored using traditional methods compared to SuperGrainbags®.

In relation to diseases and pests, SuperGrainbags® suppressed Coleopteran pests and blackspot, while storing neem alongside the seeds in LDPE bags had a slight additional pest suppressive effect.

Scoring by both men and women farmers revealed their preference for SuperGrainbags® hermetic storage. The study recommends actions for value chain development to increase farmers’ access to improved hermetic storage options at low cost.

The right time for the right place

Written by Sarah McLaughlin on September 30, 2022. Posted in Features.

Wheat is a strategically important crop for Afghanistan because as a major source of nutrition — accounting for up to 60% of a family’s daily caloric intake — it is linked directly to national food security. However, despite occupying over 2.5 million hectares of arable land across the country, Afghanistan does not currently produce enough wheat to meet the needs of a growing population. On average, annual production is estimated at around 5 million metric tons — 2 million metric tons less than needed — and as a result Afghanistan makes up this significant shortfall by importing wheat flour from neighboring countries where wheat productivity is significantly higher.

There is tremendous potential to increase national wheat productivity by introducing improved agronomic practices and making use of suitable farming technologies. However, given Afghanistan’s vast agro-ecological diversity, it is essential that best practices are recommended based on local conditions, as these vary greatly across the country.

Take seeding, for instance. Sowing wheat seed at the optimum time has been shown to help maximize yields and significant research has been undertaken to determine the optimal sowing dates for winter and spring wheat in different areas. These times are governed not only by environmental requirements and growing cycles, but also by the need to avoid certain diseases and insect pests, which may be more prevalent at specific times of year.

But these can vary widely even within a season. For example, research shows that the best time to sow irrigated winter wheat in Afghanistan’s hot and arid western provinces is from the second week of October up until the end of the month. However, the optimum window falls one month later in the more mountainous and forested provinces of the East, and even later for rain-fed wheat.

The same distinctions apply to seeding and fertilizer application rates, which can vary subtly between similar regions. Consider that the optimum seed rate for irrigated wheat sown using the broadcast method is the same in both the Northern and Central zones, 25-30 kilograms per jerib (approx. half an acre). One might expect the optimum rates for row cultivation to match, but in fact they differ by two kilograms. This might not seem like much, but given how significantly seed density and spacing influence crop yield and quality, these figures are vital knowledge for farmers looking to maximize their yield potential.

To help disseminate these research-based recommendations to farmers and local agricultural extension staff, researchers at the International Maize and Wheat Improvement Center (CIMMYT) have partnered with Afghanistan’s Ministry of Agriculture, Irrigation and Livestock, Michigan State University’s Global Center for Food Systems Innovation and the USAID to compile four new booklets featuring zone-specific advice for irrigated and rain-fed systems in each of Afghanistan’s main agro-ecological zones.

Covering between four and ten provinces each, these guides include localized recommendations for the best sowing dates, nutrient management, weed management, and best practices in irrigation, arming wheat farmers with the key information they need to effectively increase production in their area and support the country’s wider food security needs.

More information is available in the booklets below:

Tracking improved crop varieties

Coordinating the development and deployment of improved seed varieties is a complex task involving many stakeholders, including government agencies, public and private seed sector organizations, and ultimately, farmers and farmer groups. Cooperation among these groups is vital to assess and measure the impact of improved varieties and to guide decision making for future crop breeding efforts.

The Institutionalizing Monitoring of Crop Variety Adoption using Genotyping (IMAGE) project, funded by the Bill & Melinda Gates Foundation and managed by Context Global Development, is a five-year program operating in Nigeria, Tanzania, and Ethiopia designed to increase the efficacy of variety deployment by establishing, institutionalizing, and scaling up routine monitoring of improved variety adoption and turnover using genotyping technologies, focusing on wheat, maize, teff, and the common bean.

The International Center for Maize and Wheat Improvement (CIMMYT), in collaboration with the Ethiopian Institute of Agricultural Research (EIAR), launched Ethiopia’s IMAGE National Advisory Committee (NAC) February 25, 2022, in Addis Ababa.

Feto Esemo, the Director General of the Ethiopian Institute of Agricultural Research (EIAR) officially opened the workshop.

Esemo underscored in his opening remarks the NAC’s mission to promote the application of DNA fingerprinting for an accurate assessment and understanding of the adoption of improved maize and wheat varieties by small-holder farmers in Ethiopia and resolve data discrepancy among researchers.

The NAC is the highest advisory body for IMAGE’s implementation in Ethiopia and comprises seven institutions: Ministry of Agriculture (MoA), Ministry of Planning and Development (MPD), Agricultural Transformation Institute (ATI), EIAR, Central Statistical Agency (CSA), Ethiopian Biodiversity Institute (BI), and the Ethiopian Biotechnology Institute (EBI).

Kindie Tesfaye, CIMMYT senior scientist, emphasized the application of DNA fingerprint data on maize and wheat in Ethiopia and summarized the IMAGE Project.

“IMAGE supports inclusive agricultural transformation by providing insights and evidence for seed sector actors to enhance government agency capacity, improve stakeholder coordination, and lead to better resource allocation for varietal development and commercialization,” said Tesfaye.

He added the IMAGE Project provides the opportunity to leverage past monitoring pilots and cross-country lessons while advancing genetic reference libraries, establishing protocol adoption, and building towards institutionalization over five years.

National maize and wheat genotyping studies in Ethiopia proved the feasibility of using DNA fingerprinting for variety monitoring at scale and CIMMYT and EIAR presented the findings to seed system and policy stakeholders with an emphasis on demonstrating how varietal identity based on genotyping compares with farmers’ elicitation, the area-weighted average age of varieties, germplasm attribution, and varietal performance.

Chilot Yirga, Deputy Director-General, Capacity Building and Administration of EIAR, emphasized the functional and structural roles of the National Advisory Committee (NAC), Country Team (CT), and Technical Working Group (TWG) of the project in the country.

EIAR, the Holetta National Agricultural Biotechnology Research Center, CSA, and CIMMYT comprise the Country Team.

Yirga also briefed the participants on the details of the Committee’s mandate and indicated the roles of all stakeholders and policymakers, specifically in DNA fingerprinting.

The workshop concluded by electing a chairperson and vice-chairperson of the committee among its members and co-project leaders from CIMMYT and EIAR.

Setting a standard: improving field trial data

“In Afghanistan, wheat is synonymous with food,” says Rajiv K. Sharma, formerly a senior scientist at the International Maize and Wheat Improvement Center (CIMMYT). Standing at about 250kg per year, the country’s per capita consumption of the crop is among the highest in the world. However, Afghanistan does not have a robust wheat research and development system. The majority of wheat varieties have been introduced from outside the country and the national wheat seed replacement rate is one of the lowest in the world at around 5%.

In a bid to strengthen research and development and boost crop productivity in the country, CIMMYT scientists have collaborated with Michigan State University and USAID to design a new, illustrated manual for wheat researchers, intended to aid them during experiments and facilitate smooth and timely data collection. As applied wheat research requires the monitoring and measurement of both qualitative and quantitative traits by different researchers across multiple locations, consistency of approach is crucial.

As well as providing descriptions of characteristics like glaucousness (the presence or absence of leaf waxes) and advice on measuring leaf area, the manual provides several different scales for determining the extent to which a wheat plant is affected by frost damage, cereal rusts or foliar diseases like Septoria and powdery mildew. Covering everything from leaf angle to chlorophyll content, this resource ensures that scientists throughout Afghanistan are supported to follow the same observation and measurement protocols while recording trial data, ensuring a standardized approach, thus bolstering the country’s wheat research sector and ensuring the data is also aligned to international projects.

The manual has since been distributed to National Agricultural Research System (NARS) researchers and other stakeholders across the country, accompanied by a number of CIMMYT-led trainings on how best to use the resource.

Bram Govaerts, Director General of the International Maize and Wheat Improvement Center (CIMMYT), underscored the need for collaboration to address the challenges of global food shocks, climate change and agricultural trade.

Speaking at a Strengthening AR4D in South Asia workshop on Thursday, September 1, Govaerts highlighted the work of CIMMYT’s Borlaug Institute of South Asia (BISA) project.

“The collaborative, inclusive approach of BISA (Borlaug Institute for South Asia) is more relevant than ever today. In an era when the challenges of food and nutrition insecurity — exacerbated by climate change, poverty, and inequality — cannot be solved by one sector,” he explained.

Cereals research for sustainable health and well-being

Written by Sarah McLaughlin on November 8, 2021. Posted in Publications.

The current focus in nutritional circles on micronutrient malnutrition and unhealthy eating habits has raised questions about continuing to invest in research on energy-rich cereal crops and related farming systems.

In this new paper in the International Journal of Agricultural Sustainability, development scientists make the case that cereal foods are an important vehicle for enhanced nutrition – with additional improvement possible through plant breeding and interventions in processing, manufacturing and distribution. It also explains cereals are a rich source of both dietary fiber and a range of bioactive food components that are essential for good health and well-being.

The authors suggest a balanced, integrated research approach to support the sustainable production of both nutrient-rich crops and the basic cereals used in humanity’s most widely consumed and popular foods.
