Exotic wheat DNA helps breed ‘climate-proof’ crops

Written by Sarah McLaughlin on . 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.

Participatory action research identifies solutions for improved seed storage in Bangladesh

Written by Sarah McLaughlin on . 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 . 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:

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

Written by Sarah McLaughlin on . Posted in Features.

“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.

Cereals research for sustainable health and well-being

Written by Sarah McLaughlin on . 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.

The International Wheat Genome Sequencing Consortium (IWGSC) is pleased to announce that the International Maize and Wheat Improvement Center (CIMMYT), has joined the organization as a sponsoring partner.

The IWGSC is an international, collaborative consortium of wheat growers, plant scientists, and public and private breeders dedicated to the development of genomic resources for wheat scientists and breeders to facilitate the production of wheat varieties better adapted to today’s challenges – climate change, food security and biodiversity preservation. In 2018, the IWGSC published the first genome reference sequence of the bread wheat, an essential tool to identify more rapidly genes and regulatory elements underlying complex agronomic traits such as yield, grain quality, resistance to diseases, and tolerance to stress such as drought or salinity.

The International Maize and Wheat Improvement Center, known by its Spanish acronym, CIMMYT, is a non-profit international agricultural research and training organization focusing on two of the world’s most important cereal grains: maize and wheat, and related cropping systems and livelihoods. CIMMYT’s maize and wheat research addresses challenges encountered by low-income farmers in the developing world including food and nutritional insecurity, environmental degradation, economic development, population growth and climate change.

CIMMYT’s Global Wheat Program is one of the most important public sources of high yielding, nutritious, disease- and climate-resilient wheat varieties for Africa, Asia, and Latin America. CIMMYT breeding lines can be found in varieties sown on more than 60 million hectares worldwide.

“I am truly pleased that CIMMYT has re-joined the IWGSC. The current reference sequences have been absolutely essential, enabling us to design new trait-based markers for use in CIMMYT wheat breeding pipelines. There remains much to explore in characterizing wheat at the whole genome level,” said CIMMYT wheat molecular breeding laboratory lead, Susanne Dreisigacker.

Sponsors are an essential part of the IWGSC. They participate in IWGSC-led projects and, as members of the Coordinating Committee, they help shape the IWGSC priorities, strategic plans, and activities. Susanne Dreisigacker will represent CIMMYT in the IWGSC Coordinating Committee.

“CIMMYT is a leading force in developing wheat varieties for southern countries,” said Kellye Eversole, Executive Director of the IWGSC. “We are thrilled that they are joining forces with the IWGSC to build the genomic tools and resources that will ensure growers around the world have access to resilient and highly productive wheat varieties.”

After release of the wheat genome reference sequence in 2018, the IWGSC entered Phase II with activities focused on developing tools to accelerate the development of improved varieties and to empower all aspects of basic and applied wheat science. The organization recently released versions 2.1 of the reference sequence assembly and annotation, and is continuing to work with the wheat community to improve the reference sequence by gap filling and integration of manual and functional annotation. The IWGSC also is focused on securing funding for a project that will ensure that “platinum-quality” sequences, representing the worldwide wheat diversity of landraces and elite varieties, are available publicly for breeders.

About the International Wheat Genome Sequencing Consortium

The IWGSC, with 3,300 members in 71 countries, is an international, collaborative consortium, established in 2005 by a group of wheat growers, plant scientists, and public and private breeders. The goal of the IWGSC is to make a high-quality genome sequence of bread wheat publicly available, in order to lay a foundation for basic research that will enable breeders to develop improved varieties. The IWGSC is a U.S. 501(c)(3) non-profit organization. To learn more, visit www.wheatgenome.org and follow us on Twitter, Facebook, LinkedIn and YouTube.

International Wheat Yield Partnership launches European Winter Wheat Hub

Written by Marcia MacNeil on . Posted in Features.

Building on a wealth of existing investment in UK wheat research and development, including the UK Research and Innovation BBSRC-funded Designing Future Wheat programme (DFW), the International Wheat Yield Partnership (IWYP) has formed a new European Winter Wheat Hub that will accelerate research discoveries from the UK and globally into commercial plant breeding.

A public-private partnership, the IWYP-European Winter Wheat Hub will combine novel traits discovered by collaborative international teams into a range of high performing European winter wheat genetic backgrounds for assessment and use in winter wheat breeding programs.

The global agriculture companies BASF, KWS, RAGT and Syngenta, in collaboration with the UK National Institute for Agricultural Botany (NIAB), will provide a translational pipeline supporting European winter wheat improvement. In partnership with IWYP, commercial breeders will select key genetic discoveries of potential value for the European wheat community from global IWYP research projects. NIAB will then use its expertise in pre-breeding to produce genetic material for the validation and development of selected IWYP research outputs.

Joining the wider existing IWYP Hub Network of large translational pipelines operating on spring wheat at CIMMYT (the International Maize and Wheat Improvement Centre) in Mexico and the recently established NIFA-IWYP Winter Wheat Breeding Innovation Hub at Kansas State University, USA, the IWYP-European Winter Wheat Hub will ensure that cutting-edge discoveries are rapidly available to both the participating wheat breeders and to the global wheat breeding community.

“This is another excellent example of how public-private partnerships (such as the DFW, the Wheat Initiative and IWYP) can work well at both the international and national level,” said Chris Tapsell from KWS, who is leading the IWYP-European Winter Wheat Hub development.

“And this hub will help ensure that the hard work of the IWYP researchers around the world will deliver impacts that address the twin challenges of increasing wheat production for food security whilst protecting the environment.”

Jeff Gwyn, who leads the IWYP program said, “The addition of this new hub further strengthens the IWYP Hub Network and enables the development of our innovations to reach a wider industry base more rapidly. It is critical for IWYP to have its research outputs taken up and utilized for the public good. Public-private partnerships such as this further demonstrate that the IWYP initiative is filling a significant gap and creating value.”

Tina Barsby, CEO of NIAB commented, “NIAB has a strong track record in pre-breeding of wheat and particularly in working closely with commercial breeders to bring new variability to the market. We are really looking forward to helping to advance IWYP project traits into breeding programs.”

This press release was originally posted on the website of the International Wheat Yield Partnership.

The IWYP program is based on an innovative model for public funding and international scientific collaboration to address the global grand challenge of food, nutritional and economic security for the future. The model employs public-private partnerships to scale and drive its research innovations for impact. Operations require active coordination of the international research and development teams whose discovery research focuses on complementary and overlapping sets of potentially high impact novel trait targets deemed likely to underpin yield increases, such as the regulation of photosynthesis, optimal plant architecture, plant biomass distribution, and grain number and size. As the results emerge, it is possible to envisage how to combine them and therefore simultaneously remove multiple constraints affecting yields in farmers’ fields. https://iwyp.org/

NIAB is an independent plant biosciences organisation working to translate fundamental research into innovative solutions and products for the agricultural sector. The IWYP-European Winter Wheat Hub will leverage established expertise in wheat genetics and breeding at NIAB, including newly developed glasshouse and molecular laboratory facilities.

Space data applications for wheat and maize research

Written by Marcia MacNeil on . Posted in Features.

In 2017, a call for proposals from Copernicus Climate Change Service Sectoral Information Systems led the International Maize and Wheat Improvement Center (CIMMYT to collaborate with Wageningen University, the European Space Agency (ESA), and other research and meteorological organizations to develop practical applications in agricultural and food security for satellite-sourced weather data.

The project, which recently ended, opened the door to a wide variety of potential uses for this highly detailed data.

ESA collects extremely granular data on weather, churned out at an hourly rate. CIMMYT researchers, including Foresight Specialist Gideon Kruseman, reviewed this data stream, which generates 22 variables of daily and sub-daily weather data at a 30-kilometerlevel of accuracy, and evaluated how it could help generate agriculture-specific weather and climate data sets.

“For most people, the reaction would be, ‘What do we do with this?’ Kruseman said. “For us, this is a gold mine.”

For example, wind speed — an important variable collected by ESA satellites — is key for analyzing plant evaporation rates, and thus their drought tolerance. In addition, to date, information is available on ideal ago-climatic zones for various crop varieties, but there is no data on the actual weather conditions during a particular growing season for most sites.

By incorporating the information from the data sets into field trial data, CIMMYT researchers can specifically analyze maize and wheat cropping systems on a larger scale and create crop models with higher precision, meaning that much more accurate information can be generated from the trials of different crop varieties.

The currently available historic daily and sub-daily data, dating back to 1979, will allow CIMMYT and its partners to conduct “genotype by environment (GxE)” interaction analysis in much higher detail. For example, it will allow researchers to detect side effects related to droughts and heat waves and the tolerance of maize and wheat lines to those stresses. This will help breeders create specific crop varieties for farmers in environments where the impact of climate change is predicted to be more apparent in the near future.

“The data from this project has great potential fix this gap in information so that farmers can eventually receive more targeted assistance,” said Kruseman.

These ideas are just the beginning of the agricultural research and food security potential of the ESA data. For example, Kruseman would like to link the data to household surveys to review the relationship between the weather farmers experience and the farming decisions they make.

By the end of 2019, the data will live on an open access, user-friendly database. Eventually, space agency-sourced weather data from as far back as 1951 to as recent as five days ago will be available to researchers and weather enthusiasts alike.

Already CIMMYT scientists are using this data to understand the potential of a promising wheat line, for seasonal forecasting, to analyze gene-bank accessions and for a statistical analysis of maize trials, with many more high-impact applications expected in the future.
