The first meetings of the Accelerating Genetic Gains in Maize and Wheat for Improved Livelihoods (AGG) wheat and maize science and technical steering committees — WSC and MSC, respectively — took place virtually on 25th and 28th September.
Researchers from the International Maize and Wheat Improvement Center (CIMMYT) sit on both committees. In the WSC they are joined by wheat experts from national agricultural research systems (NARS) in Bangladesh, Ethiopia, Kenya, India, and Nepal; and from Angus Wheat Consultants, the Foreign, Commonwealth & Development Office (FCDO), HarvestPlus, Kansas State University and the Roslin Institute.
Similarly, the MSC includes maize experts from NARS in Ethiopia, Ghana, Kenya and Zambia; and from Corteva, the Foundation for Food and Agriculture Research (FFAR), the International Institute for Tropical Agriculture (IITA), SeedCo, Syngenta, the University of Queensland, and the US Agency for International Development (USAID).
During the meetings, attendees discussed scientific challenges and opportunities for AGG, and developed specific recommendations pertaining to key topics including breeding and testing scheme optimization, effective engagement with partners and capacity development in the time of COVID-19, and seed systems and gender intentionality.
Discussion groups noted, for example, the need to address family structure in yield trials, to strengthen collaboration with national partners, and to develop effective regional on-farm testing strategies. Interestingly, most of the recommendations are applicable and valuable for both crop teams, and this is a clear example of the synergies we expect from combining maize and wheat within the AGG project.
All the recommendations will be further analyzed by the AGG teams during coming months, and project activities will be adjusted or implemented as appropriate. A brief report will be submitted to the respective STSCs prior to the second meetings of these committees, likely in late March 2021.
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.”
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.

BASF, KWS, RAGT and Syngenta are innovation-led leaders in the wheat breeding industry, developing varieties that deliver consistent year-on-year genetics gain for the benefit of wheat growers throughout Europe and North America. All companies are active members of IWYP and launched this initiative to speed up and ensure the effective utilization of deliverables from IWYP research projects, which are funded by partners across the globe including the BBSRC in the UK.

The COVID-19 crisis is highlighting many fragilities in contemporary food systems. But the pandemic has also created opportunities for local organizations and technologies to quickly mitigate these fragilities while showcasing the resilience, innovation and adaptation of African food and agricultural systems.

While all eyes are on Lombardy, Madrid, New York and Wuhan, what do we know about the impact of COVID-19 on the rural poor and on food security in developing countries? How can the impact of the crisis be moderated? What positive breakthroughs could be provoked by this shock to move us into a better “new normal”? What can donors and implementing organizations do to support low- and middle-income countries during and beyond this crisis?
Members of the Agriculture and Rural Development working group of the international Scaling Up community of practice held a virtual meeting to discuss these questions and how scaling-up innovations could help to recover from the current crisis and mitigate future ones.
Poor rural communities are particularly vulnerable
When it comes to a highly contagious disease, being in a rural area sounds better than being in a busy city, but that is a deceptive impression. Smallholder farmers often are older than average and hence more vulnerable to the virus, and they have less access to health services.
They also depend on field laborers that are not able to travel from surrounding villages to help with planting, weeding and harvesting. To process crops, smallholder farmers need to transport crops to processing centers, which may be closed, as are the markets where they obtain agricultural inputs or sell farm products. Large international agrobusiness firms, which supply inputs and purchase local famers’ products may withdraw, at least temporarily, from the rural economies. There are already reports of farmers feeding cattle strawberries and broccoli in India, as they are unable to get their goods to the market.
Most farmers also depend on non-farm and off-farm activities for their livelihoods, as they may be field laborers for other farmers, work in the processing industry or work in construction. Interrupted transportation and closures pose serious challenges to maintain safe business continuity throughout the rural economy. The risk is not only that immediate rural production, food deliveries, exports, employment and incomes will collapse, but also that planting for next year’s crops will be disrupted.
It is key to differentiate between global and local supply chains, which will suffer in different ways. For example, in Uganda, supermarkets are open but small, informal markets are closed. In past crises, governments have focused on the survival of global value chains over local ones. Small, rural businesses are more likely to close permanently than large international ones.
Globally, international support for agriculture and rural development has been lagging in recent years. Today, the international support from aid agencies and NGOs is interrupted, as travels are restricted and community meetings are prohibited. With increased donor attention to a domestic and international health crisis, aid for rural communities may drop precipitously.

Opportunities for an improved “new normal” as we respond to the crisis
The short-term response to help minimize the impact of the COVID-19 crisis on the rural poor is critical, but we also need to support the shaping of a “new normal” where rural food systems are resilient, profitable and inclusive for poor rural communities. Members of the Scaling Up community of practice explored various ideas.
First, the COVID-19 pandemic could present opportunities to break silos and show how closely health and agriculture are related.
“COVID-19 cuts across sectors and jurisdictions in ways that single organizations and established governance structures are ill-equipped to accommodate,” said Larry Cooley, Scaling Expert and Founder and President Emeritus of Management Systems International (MSI)
For example, rural agricultural extension networks could be used to disseminate information on health awareness and education around COVID-19 and collect data on local impacts. This may cause and provide relief in the short term, but may also provide opportunities for collaboration in the long run.
“Our agricultural networks go deep into the rural areas and we are training our agri-entrepreneurs in India to disseminate health messages, products and services to help address COVID-19,” said Simon Winter, Executive Director of the Syngenta Foundation.
“At the African Development Bank we are providing emergency relief finance and re-purposing funding to have a link with COVID-19,” said Atsuko Toda, the bank’s Director of Agricultural Finance and Rural Development.
Second, a “new normal” could also mean an even stronger independence from externally funded projects, experts and solutions to more local ownership and expertise in rural areas, something that the community of practice has been promoting strongly. We could help to support more autonomy of the farmer, a strong local market and scale-up local value chains. Strengthening the capacity of small and medium enterprises linking farmers to urban markets could help ensure stability in future economic shocks.
“Governments and donor ‘projects’ looked too much at export and global value chains. I see great opportunities to scale up local and regional input and output value chains that benefit local farmers and small and medium enterprises,” said Margret Will, expert on value chains.
Third, the COVID-19 pandemic presents an opportunity to accelerate the scaling of innovations.
“Lack of access to labor could be disrupting harvesting and planting in our Feed the Future countries, accelerating an already predominant trend of migration, especially among the young, to urban areas. We see a looming need for mechanization of farms at scale, using mini-tillers, planters, harvesters and other time- and labor-saving equipment,” said Mark Huisenga, Senior Program Manager for the USAID Bureau for Resilience and Food Security.

Rural communities that use more ecological intensive practices, such as conservation agriculture and push-pull farming or safe storage practices are less dependent on external inputs and labor.
The current crisis forces us to use digital communication systems, replace human work with digital tools where possible and use technology to help target interventions. Both the public and private sector could build on this opportunity to invest in increased access to internet, electricity and other digital resources, including in impoverished areas. All these technological innovations can help farmers to better cope with the constraints of COVID-19 and any future crises or stresses to the food system, while also making agriculture more productive and more attractive to the young.
“The pandemic creates an opportunity to accelerate the use of digital technologies in smallholder agriculture, not only for extension advice but to crowdsource information about COVID-19 impacts,” said Julie Howard, Senior Advisor for the Center for Strategic and International Studies (CSIS).
Finally, COVID-19 will change our global governance system, and the agriculture, research and development sector has a role to play in this transformation. A systems change must focus on dietary diversity and food safety and security, paying attention to the rural poor in low- and middle-income countries. We can work together to scale cross-sector platforms to build solid networks and scale-up innovations to strengthen sustainable and resilient food systems.
Systems change beyond the agricultural sector, sustainability through local ownership and uptake of innovations that support profitable and resilient agricultural and related rural activities are key components of how the Scaling Up Community of Practice approaches scaling. A systems change is imminent, and it is important to support a transformation in a direction where local markets, rural labor and regional economies come out stronger in the long term. This requires vision, expertise, mobilization of resources, information sharing and crowdsourced leadership, and the network of scaling experts can contribute to this.
The Agriculture and Rural Development working group of the international Scaling Up community of practice is made up of individuals from more than 100 official donors, foundations, think tanks, research and development organizations united by their interest in scaling the impact of innovations on food security and rural poverty. Areas of particular interest for the group include designing for scale, using scaling frameworks, learning about scaling, responsible scaling, sustainability and system thinking. Members of the working group include professionals with vast experience from the field, and the group explicitly tries to learn from the application of complex concepts such as sustainability, systems change and scaling in real world settings by local actors. In addition to quarterly virtual meetings, the working group encourages and supports exchanges among its members on a variety of subjects. Participation in, and management of, the Agriculture and Rural Development working group is done on a purely voluntary basis.

The maize lethal necrosis (MLN) artificial inoculation screening site in Naivasha, Kenya, will begin its phenotyping (screening/indexing) cycle of 2020 at the beginning of January 2020, which will continue in four other intervals throughout the year. Interested organizations from both the private and public sectors are invited to send maize germplasm for screening.
In 2013, the International Maize and Wheat Improvement Center (CIMMYT) and the Kenya Agricultural & Livestock Research Organization (KALRO) jointly established the MLN screening facility at the KALRO Naivasha research station in Kenya’s Rift Valley, with support from the Bill & Melinda Gates Foundation and the Syngenta Foundation for Sustainable Agriculture.
MLN was first discovered in Kenya in 2011 and quickly spread to other parts of eastern Africa. The disease causes premature plant death and unfilled, poorly formed maize cobs, which can lead to up to 100% yield loss in farmers’ fields.
CIMMYT and partners are dedicated to stopping the spread of this deadly maize disease by effectively managing the risk of MLN on maize production through screening and identifying MLN-resistant germplasm. The MLN screening facility supports countries in sub-Saharan Africa to screen maize germplasm — for hybrid, inbred and open pollinated varieties — against MLN in a quarantined environment.
This is the largest dedicated MLN screening facility in East Africa. Since its inception in 2013, the facility has evaluated more than 200,000 accessions — more than 300,000 rows of maize — from more than 15 multinational and national seed companies and national research programs.
Partners can now plan for annual MLN phenotyping (screening/indexing) during 2020 with the schedule below. The improved and streamlined approach for MLN phenotyping should enable partners to accelerate breeding programs to improve resistance for MLN for sub-Saharan Africa.
It’s been eight years since maize lethal necrosis (MLN) was first reported on the African continent. When it appeared in Kenya’s Bomet County in 2011, a sense of panic swept across the maize sector. Experts quickly realized that all maize varieties on the market were susceptible to this viral disease, which could wipe out entire maize fields.
Spearheaded by the International Maize and Wheat Improvement Center (CIMMYT), a rapid regional response involving national agriculture research systems (NARS), national plant protection organizations and seed sector partners was set up. The response involved multiple approaches: rigorous surveillance, epidemiology research, disease management across the seed value chain, and screening and fast-tracking of the MLN-tolerant maize breeding program.
Now, CIMMYT and its partners are reflecting on the tremendous impact of transboundary coalition to contain the devastating disease.
“Country reports show there are now much less incidents of MLN in the region. We have effectively contained this disease as no new country in sub-Saharan Africa reported MLN since Ethiopia in 2014. This is a great achievement of an effective public private partnership,” noted B.M. Prasanna, Director of CIMMYT’s Global Maize Program and the CGIAR Research Program on Maize.
He was speaking at the closure workshop for the MLN Diagnostics and Management project and the MLN Epidemiology project on October 15-17, 2019, in Nairobi, Kenya. Experts from research, plant health and seed sector organizations from eastern and southern Africa reflected on the tremendous impact of the transboundary coalition to contain MLN across the region.
“The outbreak of the disease in Uganda in 2012 was a huge challenge as all the maize varieties and hybrids on the market were susceptible. With the support of CIMMYT and other partners in the national agriculture research systems, we got access to Bazooka, a high-yielding, drought- and MLN-tolerant maize variety that has helped in containing the disease,” said Godfrey Katwere, marketing manager for NASECO.
Until now, 19 MLN-tolerant and -resistant hybrids have been released, helping to keep the disease away from farmers’ fields and to stop its spillover to non-endemic countries in sub-Saharan Africa.

Science in action
The MLN screening facility, established in Naivasha in 2013, has been key to a better understanding of the disease and to setting up MLN hybrid tolerance and resistance breeding efforts. The facility, funded by the Bill & Melinda Gates Foundation and the Syngenta Foundation for Sustainable Agriculture, has supported public and private partners to screen over 200,000 germplasm with around 300,000 rows of maize.
State-of-the-art epidemiology research has been carried out to identify how the disease could be transmitted and the best diagnostics methods along the seed value chain.
MLN is caused by the combination of the maize chlorotic mottle virus (MCMV) and any of the viruses belonging to the Potyviridae family.
As part of the project, studies showed that moist soil had higher MCMV virus loads than dry soil. The studies — conducted by Benham Lockhart of University of Minnesota and Peg Redinbaugh, a professor at Ohio State University and Research Leader and Research Plant Molecular Geneticist at USDA — indicated that MCMV can stay active in runoff water, and helped in understanding how the disease is transmitted and how to define management protocols.
“Crop debris may also act as source of MCMV inoculum but for a limited period of up to two months,” said L.M. Suresh, CIMMYT Maize Pathologist, in reference to soil transmission studies conducted by CIMMYT. “A host-free period of two months is, therefore, recommended for effective management of MLN,” he noted.
Rapid and low-cost MLN-causing virus detection methods such as immunostrips and ELISA-based tests were adopted at scale.
“After optimizing the protocols for MLN viruses’ diagnosis suitable for African systems, we transferred these technologies to [national plant protection organizations] and seed companies, not just within the endemic countries but also to the non-endemic countries in southern and west Africa, through intensive trainings,” Prasanna explained. “We created a digital MLN surveillance tool under the Open Data Kit (ODK) app for NPPOs and other stakeholders to effectively carry out MLN surveillance on the ground. The survey information is captured in real time in farmers’ and seed production fields coupled with rapid immunostrips MLN tests,” he remarked.
According to Francis Mwatuni, Project Manager of the MLN Diagnostics and Management project, this proactive and collaborative surveillance network has been an important outcome that helped curb MLN from spreading to non-endemic regions. “In 2016, we only had 625 surveillance points. By 2019, the surveillance points in all the target countries stood at 2,442, which intensified the alertness on MLN presence and how to effectively deal with it,” Mwatuni said. In total, 7,800 surveillance points were covered during the project implementation period.
Over 100 commercial seed firms have also been trained on how to produce MLN-free seed to facilitate trade within the endemic nations and to ensure the disease is not transferred to the non-endemic countries via contaminated seeds.

Sustaining the fight
Researchers continue to work to lessen MLN’s resurgence or new outbreaks. In 2018, incidents in all endemic countries, except Ethiopia, declined sharply. One suggested explanation for the upsurge in Ethiopia, especially in the northwestern region, was reduced use of pesticide for fall armyworm control, as compared to previous years where heavy application of these pesticides also wiped out MLN insect vectors, such as maize thrips and aphids.
At the end of the projects, partners urged for the scale-up of second-generation MLN-tolerant and -resistant varieties. They explained farmers would fully benefit from recent genetic gains of the new improved varieties and its protection against MLN.
“Despite the success registered, MLN is still a major disease requiring constant attention. We cannot rest as we redirect our energies at sustaining and building on the gains made,” said Beatrice Pallangyo, principal agricultural officer in Tanzania’s Ministry of Agriculture, Food Security and Cooperatives.
After the success containing MLN, stakeholders suggested the need to stay alert on other transboundary pests and diseases such as the tar spot complex, which could be a major threat to Africa’s food security in case of an outbreak.

For a number of reasons, including limited interdisciplinary collaboration and a dearth of funding, revolutionary new plant research findings are not being used to improve crops.
“Translational research” — efforts to convert basic research knowledge about plants into practical applications in crop improvement — represents a necessary link between the world of fundamental discovery and farmers’ fields. This kind of research is often seen as more complicated and time consuming than basic research and less sexy than working at the “cutting edge” where research is typically divorced from agricultural realities in order to achieve faster and cleaner results; however, modern tools — such as genomics, marker-assisted breeding, high throughput phenotyping of crop traits using drones, and speed breeding techniques — are making it both faster and cost-effective.
In a new article in Crop Breeding, Genetics, and Genomics, wheat physiologist Matthew Reynolds of the International Maize and Wheat Improvement Center (CIMMYT) and co-authors make the case for increasing not only funding for translational research, but the underlying prerequisites: international and interdisciplinary collaboration towards focused objectives and a visionary approach by funding organizations.
“It’s ironic,” said Reynolds. “Many breeding programs have invested in the exact technologies — such as phenomics, genomics and informatics — that can be powerful tools for translational research to make real improvements in yield and adaptation to climate, disease and pest stresses. But funding to integrate these tools in front-line breeding is quite scarce, so they aren’t reaching their potential value for crop improvement.”
Members of the International Wheat Yield Partnership (IWYP) which focuses on translational research to boost wheat yields.
Many research findings are tested for their implications for wheat improvement by the International Wheat Yield Partnership (IWYP) at the IWYP Hub, a centralized technical platform for evaluating innovations and building them into elite wheat varieties, co-managed by CIMMYT at its experimental station in Obregon, Mexico.
IWYP has its roots with the CGIAR Research Program on Wheat (WHEAT), which in 2010 formalized the need to boost both wheat yield potential as well as its adaptation to heat and drought stress. The network specializes in translational research, harnessing scientific findings from around the world to boost genetic gains in wheat, and capitalizing on the research and pre-breeding outputs of WHEAT and the testing networks of the International Wheat Improvement Network (IWIN). These efforts also led to the establishment of the Heat and Drought Wheat Improvement Consortium (HeDWIC).
“We’ve made extraordinary advances in understanding the genetic basis of important traits,“ said IWYP’s Richard Flavell, a co-author of the article. “But if they aren’t translated into crop production, their societal value is lost.”
The authors, all of whom have proven track records in both science and practical crop improvement, offer examples where exactly this combination of factors led to the impactful application of innovative research findings.
Improving the Vitamin A content of maize: A variety of maize with high Vitamin A content has the potential to reduce a deficiency that can cause blindness and a compromised immune system. This development happened as a result of many translational research efforts, including marker-assisted selection for a favorable allele, using DNA extracted from seed of numerous segregating breeding crosses prior to planting, and even findings from gerbil, piglet and chicken models — as well as long-term, community-based, placebo-controlled trials with children — that helped establish that Vitamin A maize is bioavailable and bioefficacious.
Flood-tolerant rice: Weather variability due to climate change effects is predicted to include both droughts and floods. Developing rice varieties that can withstand submergence in water due to flooding is an important outcome of translational research which has resulted in important gains for rice agriculture. In this case, the genetic trait for flood tolerance was recognized, but it took a long time to incorporate the trait into elite germplasm breeding programs. In fact, the development of flooding tolerant rice based on a specific SUB 1A allele took over 50 years at the International Rice Research Institute in the Philippines (1960–2010), together with expert molecular analyses by others. The translation program to achieve efficient incorporation into elite high yielding cultivars also required detailed research using molecular marker technologies that were not available at the time when trait introgression started.
Other successes include new approaches for improving the yield potential of spring wheat and the discovery of traits that increase the climate resilience of maize and sorghum.
One way researchers apply academic research to field impact is through phenotyping. Involving the use of cutting edge technologies and tools to measure detailed and hard to recognize plant traits, this area of research has undergone a revolution in the past decade, thanks to more affordable digital measuring tools such as cameras and sensors and more powerful and accessible computing power and accessibility.
Scientists are now able to identify at a detailed scale plant traits that show how efficiently a plant is using the sun’s radiation for growth, how deep its roots are growing to collect water, and more — helping breeders select the best lines to cross and develop.
An Australian pine at CIMMYT’s experimental station in Texoco, Mexico, commemorates the 4th symposium of the International Plant Phenotyping Network.
Phenotyping is key to understanding the physiological and genetic bases of plant growth and adaptation and has wide application in crop improvement programs. Recording trait data through sophisticated non-invasive imaging, spectroscopy, image analysis, robotics, high-performance computing facilities and phenomics databases allows scientists to collect information about traits such as plant development, architecture, plant photosynthesis, growth or biomass productivity from hundreds to thousands of plants in a single day. This revolution was the subject of discussion at a 2016 gathering of more than 200 participants at the International Plant Phenotyping Symposium hosted by CIMMYT in Mexico and documented in a special issue of Plant Science.
There is currently an explosion in plant science. Scientists have uncovered the genetic basis of many traits, identified genetic markers to track them and developed ways to measure them in breeding programs. But most of these new findings and ideas have yet to be tested and used in breeding programs, wasting their potentially enormous societal value.
Establishing systems for generating and testing new hypotheses in agriculturally relevant systems must become a priority, Reynolds states in the article. However, for success, this will require interdisciplinary, and often international, collaboration to enable established breeding programs to retool. Most importantly, scientists and funding organizations alike must factor in the long-term benefits as well as the risks of not taking timely action. Translating a research finding into an improved crop that can save lives takes time and commitment. With these two prerequisites, basic plant research can and should positively impact food security.

The CIMMYT-Kenya Agriculture and Livestock Research Organization (KALRO) Maize Lethal Necrosis (MLN) Screening Facility quarantine site is used to provide an MLN Phenotyping Service at cost to national agricultural research systems and seed companies in Africa.
KALRO and CIMMYT have been screening germplasm against MLN in Kenya since Nov 2012. The dedicated screening facility at KALRO Naivasha was established in 2013. This facility now represents a high quality phenotyping platform, permitting large-scale screening of germplasm from regional public and private partners.
To date, close to 90 percent of materials screened at Naivasha are susceptible under artificial inoculation. However, resistant and tolerant materials have been identified. Four first-generation MLN tolerant and resistant hybrids have been released in East Africa and a further 15-20 second generation hybrids are at advanced stages of testing.
The Improved Maize for Tropical Asia (IMTA) is employing modern maize breeding techniques to develop and deploy new, climate-resilient maize hybrids, including traits important for identified niche markets across tropical Asia.
Smallholder maize farmers in marginal environments in Asia are prone to drought due to either scanty/erratic rainfall or falling groundwater levels.
The Affordable, Accessible, Asian (AAA) Drought Tolerant Maize Project is a partnership among CIMMYT, the Syngenta Foundation for Sustainable Agriculture, national agricultural research systems of Indonesia, Philippines and Vietnam to develop drought-tolerant maize for smallholder farmers in Asia.
AAA combines complementary technologies and comparative advantages, such as CIMMYT’s global expertise in drought-tolerant maize breeding, Syngenta’s elite germplasm bred for Asia, the national partners’ local knowledge of farmers’ requirements and their germplasm testing network.
This project covers a gamut of upstream and downstream activities: marker discovery (genome-wide association studies); trait discovery (understanding root structure and function-lysimetrics); marker applications (genomic selection); drought phenotyping facilities (rhizotronics, rain-out shelters; managed drought stress screening locations); germplasm development; hybrid deployment; and linking with potential hybrid commercialization partners.

DES MOINES (Iowa) — Hundreds of food and agriculture leaders from around the world gathered last week in Iowa, USA, for the 2018 edition of the Borlaug Dialogue. Much of the conversation this year was centered on how to “take it to the farmer,” as Norman Borlaug famously said. Experts discussed how to build sustainable seed systems, grounded on solid science, so improved varieties reach smallholder farmers.

Louise Sperling, senior technical advisor at Catholic Relief Services, presented a study on the sources of seed for smallholder farmers in Africa. She explained that 52.2 percent of households receive new varieties, but only 2.8 percent of the seed comes through agro-dealers. The biggest source is local markets and own stock, the so-called informal channels.
Quality and variety of seed should be the focus, emphasized Jean Claude Rubyogo, seed systems specialist at CIAT. In his view, we need to integrate formal and informal seed distribution channels, using the competitive advantages of each.
“When we take good seed, we address all African soil,” said Ruth Oniang’o, board chair at the Sasakawa Africa Foundation. Oniang’o explained access to financing is a major hurdle for smallholders to access better seed and other innovations. In her view, current financial products are inadequate. “Why should we get a farmer to pay 20 percent interest rates on a small loan?”
B.J. Marttin, member of the managing board of Rabobank Group, recommended financial institutions to partner with farmers through every stage, from production to sale, so they better understand risk and the whole value chain. Simon Winter, executive director of the Syngenta Foundation for Sustainable Agriculture, captured the main points from the session on financing for agricultural entrepreneurs. “We have to have the farmer at the center. The farmer is the ultimate customer,” Winter said. “If we are not serving farmer needs, we are not really solving the problems.”
Research to feed the world
The 2018 Global Agricultural Productivity (GAP) Report, presented at the Borlaug Dialogue, shows the growing gap between future food supply needs and agricultural production, particularly in low-income countries. To meet the projected food needs of nearly 10 billion people in 2050, global agricultural productivity must increase by 1.75 percent annually, the report states, but has only increased 1.51 percent annually since 2010.
A plenary session led by CGIAR explored the role of research in tackling this and other complex challenges. “We have to talk about food and agriculture research,” said former U.S. Secretary of Agriculture Dan Glickman. People need to understand research is not abstract academic knowledge, but rather useful innovation that goes “from the farm, to the table and to the stomach,” he explained.
“Innovation, no matter where you are in the world, is key to moving forward,” said Patience Koku, a farmer from Nigeria part of the Global Farmer Network. “I don’t think the farmers in Africa or in Nigeria need a lot of convincing” to adopt innovation, Koku noted. If someone is able to explain what a new technology can do, “farmers see that science can make their life better and embrace it.”
Rising to the challenge
Agricultural research is also crucial to confront global threats like pests, conflict and climate change.

Two separate sessions, hosted by Corteva Agriscience and CIMMYT, shared the latest approaches in the fight against fall armyworm and other pests and diseases. The Director General of the International Maize and Wheat Improvement Center (CIMMYT), Martin Kropff, explained how organizations are working together to respond to the rapid spread of fall armyworm in Africa and Asia. “We have to solve the problem based on science, and then develop, validate and deploy integrated pest management approaches,” Kropff said.
As part of the World Food Prize outreach program, Bram Govaerts, director of innovative business strategies at CIMMYT, gave a lecture to students at Brody Middle School about the importance of agriculture and food. “When people can’t grow crops or pay for food to feed their families, desperation turns to conflict.”
At a side event, the Economist Intelligence Unit presented the Global Food Security Index 2018, which ranks food systems in 113 countries based on affordability, availability, and quality and safety. Senior consultant Robert Powell explained that the index now includes an adjustment factor based on each country’s natural resource risks and resilience to the impacts of a changing climate. “All countries will experience the impact of climate change,” Powell said.
The pernicious effects of climate change were also evident to the 2018 World Food Prize winners, David Nabarro and Lawrence Haddad, who have led global efforts to curb child malnutrition. “There is no evidence to me that [this] crisis is going to stop, because climate change is here,” Nabarro declared. “The foods we choose to grow and eat have a large impact on emissions,” Haddad said. “Food has a lot to offer” on climate mitigation and “diversity is the secret sauce” for climate adaptation. “We need food systems that are diverse: in crops, locations, organizations involved in them…”
Less biodiversity translates into “less resilience and worse nutrition,” according to the Vice President of Peru, Mercedes Aráoz. Through improved health and nutrition services, the country more than halved malnutrition among children under five, from 28 percent in 2008 to 13.1 percent in 2016.

A rallying cry for nutrition
The impact of nutrition on the first 1,000 days of life lasts a lifetime, explained Haddad. “For young kids, these are permanent shocks.”
“If a person is not nourished in those very important weeks and months of life, the long-term consequences are likely to be irreversible,” Nabarro added. According to him, nutrition needs to be the target in the 2030 agenda, not only hunger.
“Nutrition-based interventions present us a new lens through which to create and assess impact as agricultural researchers,” said Elwyn Grainger-Jones, the executive director of the CGIAR System Organization. “Our future success must come not only from ensuring an adequate supply of calories for the global population, but also the right quality and diversity of foods to tackle hidden hunger as well.”
“We are not going to resolve the challenges of undernutrition without the ag sector stepping up in a big way and differently,” argued Shawn Baker, director of nutrition at the Bill & Melinda Gates Foundation. “Nutrition needs you,” Baker told other participants. “Welcome to the nutrition family.”
NAIROBI (Kenya) — Members of the International Maize Improvement Consortium (IMIC) and other partners had a chance to go on a field visit to the Kiboko and Naivasha research stations in Kenya on September 18 and 19, 2018. The International Maize and Wheat Improvement Center (CIMMYT) and the Kenya Agriculture & Livestock Research Organization (KALRO) held their annual partner field days to share the latest developments in maize and wheat research.
On the first day, CIMMYT invited IMIC researchers to evaluate Material Under Development at the Kiboko site. These maize lines are not publicly released yet but are available to IMIC partners, so they can select the most promising ones for their research and crop improvement work.
Each seed company was looking for certain traits to develop new hybrid varieties. For instance, Samit Fayek, from Fine Seeds Egypt was looking for ‘erect type’ maize, as he wants higher crop density and grains that look big. Christopher Volbrecht, from Lake Agriculture in South Africa, was looking for “cobs that stick out as this is what farmers want.” Josephine Okot, from Victoria Seeds in Uganda, said that “seed companies often look at drought tolerance only, but we need now to integrate resistance to Maize Lethal Necrosis.”

Next on the tour to Kiboko, partners visited various stress-tolerant breeding materials, sustainable intensification cropping demonstrations and the Doubled Haploid facility. Vijaya Chaikam, Maize Doubled Haploid Scientist, explained how CIMMYT uses this methodology to cut down breeding time from six to two cycles, which drastically reduces costs.
According to B.M. Prasanna, director of CIMMYT’s Global Maize Program and the CGIAR Research Program MAIZE, doubled haploid breeding is possibly the biggest innovation to speed up genetic gain since the inception of hybrid technology a century ago. “In the next 4 or 5 years, CIMMYT aims at 80 percent use of double haploid lines for new hybrid development; breeding will be faster and much cheaper that way,” Prasanna said. “For now, breeders and seed companies need to know how to use double haploid lines to cost-efficiently crossbreed with their varieties for high-quality hybrids.”
At the end of the visit to Kiboko, CIMMYT officially opened a new maize seed storage cold room. This facility will serve to keep seeds in good condition and to better manage inventory. At the opening were the director of KALRO’s Food Crops Research Institute, Joyce Malinga, CIMMYT’s Africa Regional Representative, Stephen Mugo, and CIMMYT’s Technical Lead for the Global Maize Program, Aparna Das.

On the second day, partners visited the Naivasha research station. There, CIMMYT presented the latest efforts to contain Maize Lethal Necrosis (MLN), a devastating maize viral disease first reported in Kenya in 2011 which caused severe crop losses across Eastern Africa, causing severe crop losses. The Naivasha research station is home to a world-class facility to screen for Maize Lethal Necrosis, jointly managed by CIMMYT and KALRO.
At the facility, maize lines are evaluated for MLN resistance. The best lines and varieties are nominated for further development and shared with partners. National Agriculture Research partners can request MLN screening at no cost, while private seed companies are charged for the service. In the last four years, more than 150,000 germplasm have been screened.
CIMMYT wheat scientist Mandeep Randhawa explained how to recognize the different types of wheat rust diseases: stem, stripe and leaf rusts. He emphasized the Ug99 black stem rust strain, which appeared in Uganda in 1998 and has since severely impacted wheat production in the region and globally. Randhawa explained how CIMMYT develops varieties resistant to stem rust using a phenotyping platform and marker-assisted selection.
These two field days were a great opportunity to showcase progress in developing more resilient maize varieties in a fast and cost-effective way. This responsiveness is crucial as pests and diseases continue to threaten the livelihoods of African smallholders. Such impact could not happen without the strong collaboration between CIMMYT and KALRO.

The Doubled Haploid Facility in Kiboko and the Maize Lethal Necrosis screening facilty in Naivasha were opened in 2013 with support from the Bill & Melinda Gates Foundation and the Syngenta Foundation.
The International Maize Improvement Consortium (IMIC) is a public-private partnership initiative launched in May 2018 as part of CIMMYT’s mission to ramp up seed breeding and production innovations.
The third installment of the 2018 maize lethal necrosis (MLN) phenotyping (screening/ indexing) cycle will be held in July 2018 at the MLN artificial inoculation screening site in Naivasha, Kenya. Interested organizations from both the private and public sectors are invited to send maize germplasm for screening.
CIMMYT and partners are dedicated to stopping the spread of this deadly maize disease by effectively managing the risk of MLN on maize production through screening and identifying MLN-resistant germplasm. The MLN screening facility supports countries in sub-Saharan Africa to screen maize germplasm (for hybrid, inbred and open pollinated varieties) against MLN in a quarantined environment.
This is the largest dedicated MLN screening facility in East Africa. Since its inception in 2013, the facility has evaluated more than 120,000 accessions (more than 210,000 rows of maize) from more than 15 multinational and national seed companies and national research programs.
Partners can now plan for annual MLN Phenotyping (Screening / Indexing) during 2018 with the below mentioned schedule. The improved and streamlined approach for MLN phenotyping should enable our partners to accelerate breeding programs to improve resistance for Maize MLN for sub-Saharan Africa.

The maize lethal necrosis (MLN) artificial inoculation screening site in Naivasha, Kenya will begin its phenotyping (screening/ indexing) cycle of 2018 at the begining of January 2018 and in four other intervals. Interested organizations from both the private and public sectors are invited to send maize germplasm for screening.
MLN was first discovered in Kenya in 2011 and quickly spread to other parts of eastern Africa; the disease causes premature plant death and unfilled, poorly formed maize cobs, and can lead to up to 100 percent yield loss in farmers’ fields.
