Crop breeding and soil management must go hand in hand

Written by Emma Orchardson on December 8, 2020. Posted in Blogs.

There is a growing crisis beneath our feet. Scientists, soil specialists and policy-makers around the world are sounding the alarm about degrading soil conditions. And it is particularly stark in developing countries. In fact, about 40 per cent of soils in sub-Saharan Africa are already of poor quality.

Declining soil health causes poor crop yields, leading to further pressure on the soils as farmers struggle to meet food demands and eke out a living. Many farmers lack access to information or technologies to get out of this vicious cycle. If you are a farmer with the need to increase your yield in the face of these challenges, crop breeding and soil management offers a range of solutions as part of an Integrated Soil Fertility Management (ISFM) approach.

For instance, breeding programs which partner with CGIAR Excellence in Breeding (EiB) are working to deliver the best seed varieties for farmers to help them withstand harsh conditions and increase yields. Alongside this work, researchers are supporting farmers to adopt better agronomic practices, such as minimum tillage farming, crop rotation, proper spacing and planting date practices, the use of terracing or intercropping, or techniques to reduce water use.

Of course, breeding cannot happen in a vacuum. To protect soils and produce quality yields, these cropping measures should be closely matched to the best, context-appropriate soil management practices available to farmers, for instance around the type and timing of mineral fertilizer, along with organic sources like crop residues, compost or manure.

Indeed, a combination will bring the best results. But most of the time accessing either improved variety or best agronomic practice represent a challenge for farmers in low income countries.

Here are three ways crop breeders can ensure they deliver the best seeds and create the best conditions for long-term crop production.

Include farmers, agronomic experts and extension services when defining product requirements

Strong connections among public breeding programs and extension and agronomic groups are vital. There is growing discussion regarding how to broaden our work to better consider all the factors that contribute to a successful breeding scheme: genotyping, environment and management (GxExM). However, defining the management component is not easy. Do we breed for conditions that farmers are actually working with, or breed for conditions that they should adopt?

A key to answer this question is a strong breeding team defining the traits needed and wanted by farmers. To design the best product profile, it is imperative to involve extension teams and other groups that work on the development of sustainable agronomic practices.

Properly manage research stations

Attention also needs to focus on the sustainability practices within research stations. It is all too easy to find degraded soil in public research stations. There are many reasons for this: inadequate long-term planning, lack of organized management structures, insufficient connections between breeding and agronomic teams, and lack of resources, to name a few.

Public research stations must serve as an example for the farmers in that specific region. Thus, it is not only what products we develop that matters, but also how we develop them. If we develop a good variety at the research station, but do so without adopting good agronomic practice, what example has been set for farmers and future generations? We need to ensure we invest in the best soil management practices along every step of the research phase.

Breed for specific soil characteristics

Once the breeding target is known, breeding for specific soil conditions is critical. This means developing varieties for soil conditions such as nutrient deficiencies or high salinity levels. CGIAR breeding programs have put in tremendous efforts with great impact here.

For example, AfricaRice and partners developed rice varieties branded ARICA (Advanced Rice Varieties for Africa) to be salt or iron toxicity tolerant, among other traits. This is helping farmers who farm under predominantly rainfed conditions, in which soils and yields are threatened by floods, droughts and toxicity.

Another standout product is Stress Tolerant Maize for Africa (STMA), led by the International Maize and Wheat Improvement Center (CIMMYT) and the International Institute of Tropical Agriculture (IITA). Breeders have developed varieties that can thrive in low soil fertility conditions, along with resistance to other stresses such as pests and drought. The project has seen the adoption of new maize varieties by more than six million households across 13 countries, with some farms increasing yields by over 150 per cent.

Our soils depend on breeding for the future. Breeding is showing real results for improving yields, delivering better food, and increasing smallholder incomes. But its impact on ecosystems could go either way. With the right investments in relationships, good research practices, and delivering varieties matched to particular soil conditions, we can breed for the present and for the future.

It is time to invest in both crop breeding and soil management — as one vital package of innovations.

Building networks and capacity

Written by Shiela Chikulo on November 30, 2020. Posted in News.

The active involvement of partners in the co-design of project and capacity building activities is key to the success of the Accelerating Genetic Gains in Maize and Wheat for Improved Livelihoods (AGG) project, led by the International Maize and Wheat Improvement Center (CIMMYT). To that end, the AGG Regional Collaborative Breeding and Testing Networks launched with virtual meetings on September 14 and 15 for southern African partners, and October 28 and November 2 for eastern African partners.

In addition, the AGG team collaborated with researchers from the Excellence in Breeding (EiB) Platform on a number of capacity development webinars in October and November, on topics including Continuous Improvement for breeding processes, programs and products, enhancing and measuring genetic gain in crop breeding, and a three-webinar series on statistical analysis for plant breeders with CIMMYT’s Biometrics and Statistics Unit.

These training events and regional meetings provided opportunities for well over 100 breeders from CIMMYT, national agricultural research systems (NARS) and seed companies to refresh their capacities to improve genetic gains, and to collectively review and discuss upcoming project activities, current issues of interest, and broader project objectives within their current regional context.

Several themes of importance to partners emerged during the network virtual meetings, for attention in future AGG activities and capacity development work.

Gender inclusion and the impact of COVID-19

Ugandan partners, including Godfrey Asea, director of the National Crops Resources Research Institute at Uganda’s National Agricultural Research Organization, and Josephine Okot, founder and managing director of Victoria Seeds, applauded the project’s emphasis on inclusion of women’s knowledge and preferences in breeding programs.

“We notice that this time there is a lot of focus on gender-inclusiveness,” remarked Asea. “I can tell you there is need for enhanced capacity building for both the private sector and research in proper gender inclusion.”

They also noted the importance of building local capacity, not just for food security but also for other value chain items like raw materials. “COVID-19 has demonstrated to all policy-makers that we cannot depend on the global supply chains,” said Okot. “How can we leverage this project if, for instance, some private sector actors want to [know] the appropriate protein-content maize for, say, animal feed?”

Demand for knowledge

NARS members in Tanzania requested increased support on how to measure or assess genetic gains, especially at the national level, to allow them to establish a baseline upon which genetic gains would be pegged for the project lifecycle.

With statistics an essential element to plant breeding — from analyzing yield trials to ranking varieties — the webinar series in Statistical Analysis for Plant Breeders was a first step towards meeting these capacity development needs.

“The idea of this webinar series was to share insights on how we can improve the breeding plans using statistical methods in an effective way,” said Juan Burgueño, the head of CIMMYT’s Biometrics and Statistics Unit. “The training offered both theory and hands-on experience using open-access software.”

Reaching farmers

Looking beyond breeding, meeting participants also discussed how to improve access and adoption of improved varieties among farmers.

“For a large country such as Tanzania, it is at times very hard to reach the farmers,” said Zabron Mbwaga, managing director of the Tanzania-based Beula Seed Company and Consultancy Limited. “We may have a lot of seed in the store, but how to get the farmers to adopt the newer varieties is quite difficult. This is more so when farmers tend to stick to varieties which they know well and are always reluctant to adopt the new varieties,” he explained.

“We need to put in a lot of effort to set up demonstration farms and enhance other awareness-raising activities such as radio programs so that farmers can know about the new varieties.”

This interest in working with smallholder farmers along the entire value chain was echoed by partners in southern Africa.

“Through this project, we would like to explore ways of collaborating along the whole value chain — as the Agriculture Research Council, other partners and small to medium enterprises — to make it an effective chain,” said Kingstone Mashingaidze, senior research manager at the South Africa Agricultural Research Council. “By planning together, we can identify best-fits for all activities in the value chain and ultimately benefit the smallholder farmers.”

About the AGG Regional Collaborative Breeding and Testing Networks

The AGG Regional Collaborative Breeding and Testing Networks aim to improve breeding efficiencies among partners by enabling the use of modern tools and approaches and enriching the existing network of research organizations, public and private seed companies, farmers’ organizations, non-governmental organizations and community-based organizations. It is expected that these networks will lead to increased efficiency and communications across the partnership network and within countries, improved sharing of best practices and protocols, and increased collective ownership of products for accelerated variety development and turnover.

The virtual meetings for the Regional Collaborative Breeding and Testing Network for southern Africa convened participants from Malawi, Mozambique, South Africa, Zambia and Zimbabwe, while meetings for eastern Africa had participants from Ethiopia, Kenya, Tanzania and Uganda.

Faster results at a lower cost

Written by Emma Orchardson on November 19, 2020. Posted in Blogs.

The current COVID-19 pandemic — and associated measures to reduce its spread — is projected to increase extreme poverty by 20%, with the largest increase in sub-Saharan Africa, where 80 million more people would join the ranks of the extreme poor. Accelerating the process of delivering high-quality, climate resilient and nutritionally enriched maize seed is now more critical than ever.However, developing these varieties is not a rapid or cheap process. Over the course of five years, researchers on the Stress Tolerant Maize for Africa (STMA) project developed a range of tools and technologies to reduce the overall cost of producing a new high yielding, stress tolerant hybrids for smallholder farmers in the region.

Maize breeding starts with crossing two parents and essentially ends after testing their great-great-great-great grandchildren in as many locations as possible. This allows plant breeders to identify the new varieties which will perform well in the conditions faced by their target beneficiaries — in the case of STMA, smallholder farmers in Africa. In other parts of the world, new tools and technologies are routinely added to breeding programs to help reduce the cost and time it takes to produce new varieties.

Scientists on the STMA project focused on testing and scaling new tools specifically for maize breeding programs in sub-Saharan Africa and began by taking a closer look at the most expensive part of the breeding process: phenotyping or collecting precise information on plant traits.

“Within a breeding program, phenotyping is the single most costly step,” explains CIMMYT molecular breeder Manje Gowda. “Molecular technologies provide opportunities to reduce this cost.” The research team tested two methods to speed up this step and make it more cost efficient: forward breeding and genomic selection.

Speeding up a long and costly process

Two important traits maize breeders look for in their plant progeny are susceptibility for two key maize diseases: maize streak virus (MSV) and maize lethal necrosis (MLN). In traditional breeding, breeders must extensively test lines in the field for their susceptibility to these diseases, and then remove them before the next round of crossing. This carries a significant cost.

Using a process called forward breeding, scientists can screen for DNA markers known to be associated with susceptibility to these diseases. This allows breeders to identify lines vulnerable to these diseases and remove them before field testing.

Scientists on the STMA project applied this approach in CIMMYT breeding programs in eastern and southern Africa over the past four years, saving an estimated $300,000 in field costs. Under the AGG project, research will now focus on applying forward breeding to identify susceptibility for another fast-spreading maize pest, fall armyworm, as well as extending use of this method in partners’ breeding programs.

Forward breeding is ideal for “simple” traits which are controlled by a few genes. However, other desired traits, such as tolerance to drought and low nitrogen stress, are genetically complex. Many genes control these traits, with each gene only contributing a little towards overall stress tolerance.

In this case, a technology called genomic selection can be of service. Genomic selection estimates the performance, or breeding value, of a line based largely on genetic information. Genomic selection uses more than 5,000 DNA markers, without the need for precise information about what traits these markers control. The method is ideal for complicated traits such as drought and low nitrogen stress tolerance, where hundreds of small effect genes together largely control how a plant grows under these stresses.

CIMMYT scientists used this technology to select and advance lines for drought tolerance. They then tested these lines and compared their performance in the field to lines selected conventionally. They found that the two sets of resulting hybrid varieties — those advanced using genomic selection and those advanced in the field — showed the same grain yield under drought stress. However, genomic selection only required phenotyping half the lines, achieving the same outcome with half the budget.

Innovations in the field

While DNA technology is reducing the need for extensive field phenotyping, research is also underway to reduce the cost of the remaining necessary phenotyping in the field.

Typically, many traits — such as plant height or leaf drying under drought stress — are measured by hand, using the labor of large teams of people. For example, plant and ear height is traditionally measured by a team of two using a meter stick.

Mainasarra Zaman-Allah, a CIMMYT abiotic stress phenotyping specialist based in Zimbabwe, has been developing faster, more accurate ways to measure these traits. He implemented the use of a small laser sensor to measure plant and ear height which only requires one person. This simple yet cost effective tool has reduced the cost of measuring these traits by almost 60%. Similarly, using a UAV-based platform has reduced the cost of measuring a trait known as canopy senescence — leaf drying associated with drought susceptibility —by over 65%.

The identification of plants which are tolerant to key diseases has traditionally involved scoring the severity of disease in each plot visually, but walking through hundreds of plots daily can lead to errors in human judgement. To combat this, CIMMYT biotic stress phenotyping specialist LM Suresh collaborated with Jose Luis Araus and Shawn Kefauver, scientists at the University of Barcelona, Spain, to develop image analysis software that can quantify disease severity, thereby avoiding problems associated with unintentional human bias.

Plant breeders need uniform, or homozygous, lines for selection. With conventional plant breeding this is difficult: no matter how many times you cross a line, a small amount of DNA will remain heterozygous — having two different alleles of a particular gene — and reduce accuracy in line selection.

A technology called doubled haploid allows breeders to develop homozygous lines within two seasons. While this technology has been used in temperate maize breeding programs since the 1990s, it was not available for tropical environments until 10 years ago. In 2013, thanks to joint work with Kenyan partners at the CIMMYT Doubled Haploid facility in Kiboko, this technology was made available to African breeding programs. Now Vijay Chaikam, a CIMMYT doubled haploid specialist based in Kenya, is working towards reducing the cost of this technology as well.

The efforts begun by the STMA research team is now continuing under the Accelerating Genetic Gains in Maize and Wheat for Improved Livelihoods (AGG) project. As this work is carried forward, the next crucial step is ensuring that the next generation of African maize breeders have access to these technologies and tools.

“Improving national breeding programs will really drive success in raising maize yields in the stress prone environments faced by many farmers in our target countries,” says Mike Olsen, CIMMYT’s upstream trait pipeline coordinator. Under AGG, in collaboration with the CGIAR Excellence in Breeding Program, these tools will be scaled out.

Digital revolution can transform agri-food systems

Written by Alison Doody on November 4, 2020. Posted in Features.

A digital transformation is changing the face of international research for development and agri-food systems worldwide. This was the key takeaway from the 4^th annual CGIAR Big Data in Agriculture Convention held virtually last month.

“In many countries, farmers are using data to learn about market trends and weather predictions,” said Martin Kropff, director general of the International Maize and Wheat Improvement Center (CIMMYT), in a video address to convention participants. “But many still do not have access to everything that big data offers, and that is where CIMMYT and partners come in.”

As a member of CGIAR, CIMMYT is committed to ensuring that farmers around the world get access to data-driven solutions and information, while at the same time ensuring that the data generated by farmers, researchers and others is used ethically.

According to CGIAR experts and partner organizations, there are four key areas with the potential to transform agriculture in the next 10 years: data, artificial intelligence (AI), digital services and sector intelligence.

Key interventions will involve enabling open data and responsible data use, developing responsible AI, enabling and validating bundled digital services for food systems, and building trust in technology and big data — many of which CIMMYT has been working on already.

Harnessing data and data analytics

Led by CIMMYT, the CGIAR Excellence in Breeding (EiB) team have been developing the Enterprise Breeding System (EBS) — a single data management software solution for global breeding programs. The software aims to provide a solution to manage data across the entire breeding data workflow — from experiment creation to analytics — all in a single user-friendly dashboard.

CIMMYT and partners have also made significant breakthroughs in crop modelling to better understand crop performance and yield gaps, optimize planting dates and irrigation systems, and improve predictions of pest outbreaks. The Community of Practice (CoP) on Crop Modeling, a CGIAR initiative led by CIMMYT Crop Physiologist Matthew Reynolds, aims to foster collaboration and improve the collection of open access, easy-to-use data available for crop modelling.

The CIMMYT-led Community of Practice (CoP) on Socio-Economic Data continues to work at the forefront of making messy socio-economic data interoperable to address urgent and pressing global development issues in agri-food systems. Data interoperability, one of the foundational components of the FAIR data standards supported by CGIAR, addresses the ability of systems and services that create, exchange and consume data to have clear, shared expectations for its content, context and meaning. In the wake of COVID-19, the world witnessed the need for better data interoperability to understand what is happening in global food systems, and the CoP actively supports that process.

Improving data use and supporting digital transformation

In Ethiopia, the MARPLE (Mobile And Real-time PLant disEase) diagnostic kit — developed by CIMMYT, the Ethiopian Institute of Agricultural Research (EIAR) and the John Innes Centre (JIC) — has helped researchers, local governments and farmers to rapidly detect diseases like wheat rust in the field. The suitcase-sized kit cuts down the time it takes to detect this disease from months to just 48 hours.

In collaboration with research and meteorological organizations including Wageningen University and the European Space Agency (ESA), CIMMYT researchers have also been developing practical applications for satellite-sourced weather data. Crop scientists have been using this data to analyze maize and wheat cropping systems on a larger scale and create more precise crop models to predict the tolerance of crop varieties to stresses like drought and heatwaves. The aim is to share the climate and weather data available on an open access, user-friendly database.

Through the AgriFoodTrust platform — a new testing and learning platform for digital trust and transparency technologies – CIMMYT researchers have been experimenting with technologies like blockchain to tackle issues such as food safety, traceability, sustainability, and adulterated and counterfeit fertilizers and seeds. Findings will be used to build capacity on all aspects of the technologies and their application to ensure this they are inclusive and usable.

In Mexico, CIMMYT and partners have developed an application which offers tailored recommendations to help individual farmers deal with crop production challenges sustainably. The AgroTutor app offers farmers free information on historic yield potential, local benchmarks, recommended agricultural practices, commodity price forecasting and more.

Stepping up to the challenge

As the world becomes increasingly digital, harnessing the full potential of digital technologies is a huge area of opportunity for the agricultural research for development community, but one that is currently lacking clear leadership. As a global organization already working on global problems, it’s time for the CGIAR network to step up to the challenge. Carrying a legacy of agronomic research, agricultural extension, and research into adoption of technologies and innovations, CGIAR has an opportunity to become a leader in the digital transformation of agriculture.

Currently, the CGIAR System is coming together as One CGIAR. This transformation process is a dynamic reformulation of CGIAR’s partnerships, knowledge, assets, and global presence, aiming for greater integration and impact in the face of the interdependent challenges facing today’s world.

“One CGIAR’s role in supporting digitalization is both to improve research driven by data and data analytics, but also to foster the digitalization of agriculture in low and lower-middle income countries,” said CIMMYT Economist Gideon Kruseman at a session on Exploring CGIAR Digital Strategy at last month’s Big Data convention.

“One CGIAR — with its neutral stance and its focus on global public goods — can act as an honest broker between different stakeholders in the digital ecosystem.”

Webinar explores continuous improvement approach to plant breeding

Written by Marcia MacNeil on October 26, 2020. Posted in News.

A recent webinar organized by the CGIAR Excellence in Breeding Platform (EiB) and Accelerating Genetic Gains in Maize and Wheat for Improved Livelihoods (AGG) project, invited national agricultural research systems, seed companies, other interested breeders to explore tools, techniques and transitions toward a continuous improvement culture in breeding.

Continuous improvement (CI) is an approach that is being used to modernize breeding programs, to ensure they consistently get significantly improved varieties in farmers’ fields. It helps teams create a new way of thinking and working. The goal is to ensure striving for excellence becomes part of an organizational culture. To get there, CI provides a set of clear principles and tools to help diagnose problems and then solve them.

The webinar featured a leading international CI expert —Theresa Heitman, an EiB consultant — who introduced the Lean Improvement Methodology, an approach to help breeders grow their programs and improve results without adding more resources. It examines the way breeders create value for the customer, using specific methods and tools to reduce or eliminate non-value added activities.

Other presenters included B.M. Prasanna from the CGIAR Research Program on Maize, Gustavo Teixeira and Theresa Heitman from EiB and Dan Makumbi from EiB and the International Maize and Wheat Improvement Center (CIMMYT), Marcelo Almeida from Syngenta, and Sharifah Shahrul from the International Rice Research Center (IRRI).

The CI webinar is part of a series of webinars co-organized by EiB and AGG. Forthcoming sessions will cover assessing genetic gains and other topics.

Seed Seekers, Seed Keepers, Seed Growers

Seed banks may be another resource for securing Indigenous seed, although these banks have other missions as well. The International Maize and Wheat Improvement Center (CIMMYT), maintains seed banks and programs to preserve seeds native to specific regions. The group also leads the CGIAR Research Programs on Maize and Wheat and the Excellence in Breeding Platform to characterize genetic diversity so it can be used in conventional breeding programs to develop wheat and maize varieties that can address climate change, pest and disease resistance and yield to help manage food security.

“About 100 seed banks exist worldwide with seed used for cultural or heritage purposes and for production. CIMMYT has varieties that have been cultivated, conserved and cherished as grain and food crops for thousands of years,” says Tom Payne, head of the non-profit organization’s wheat germplasm collections and International Wheat Improvement Network. “Our seed bank conserves varieties that can be a source for finding old genes that will solve new problems. We have to have that diversity to address changing production environments.”

CGIAR breeding programs need more than just tech upgrades — they need change management

Written by Rodrigo Ordóñez on September 17, 2020. Posted in Blogs.

Did you know that vehicles with steering wheels on the left are often cheaper to make than right hand-drive cars? They are mass-produced in much larger batches. But many drivers and governments were just unwilling to change to this dominant design.

We humans are not so adept at change. Instead of embracing novel ways of thinking, we’d rather stick to the old ones. We cling onto what is safe, what is familiar or what we are already good at. We see this in the workplace, in our personal lives and in society as a whole. The world still can’t agree on using the metric system!

Within the domain of plant breeding, we are both driving and responding to rapid change. It is mesmerizing to visualize the changes gene editing is about to deliver, not to mention what genomic prediction is already delivering. We are being challenged on every single aspect of plant breeding.

Change of a different sort is about to cascade through the world’s main network of agricultural research centers — which includes centers at the global forefront of plant breeding. CGIAR is embarking on a transition into a much more integrated One CGIAR organization.

An overarching goal of this integration is no other than to ensure breeding improvement plans — and the changes they aim to drive — are implemented as seamlessly and quickly as possible. The Excellence in Breeding Platform is both driving and supporting this change among CGIAR centers and international and national partners.

The case for change in plant breeding programs

Plant breeders are in fact missing some vital opportunities. For example, there continues to be a rather limited use of real market insights to inform resource allocation within programs. This in turn results in a selection of traits weighted towards what breeders and associated scientists think are needed, which may not necessarily meet actual market needs.

With new goals and structures foisting change on breeding programs, their success depends on one thing above all else: savvy change management. Fortunately, there are some steps we can take to manage change well.

1. Drive out complacency with a sense of urgency

Most change management efforts fail when insufficient urgency is built early enough in the process. But this urgency can be the most effective antidote against complacency. Organizations that have either secured a very dominant and successful position in the market, or lack effective and threatening competition, can very easily slide into a sense of self-righteousness and an inward-looking perspective.

Although CGIAR breeding efforts could be thought of as an example of the latter — lacking competitors — seasoned managers in industry and marketing like to think that “there is no such thing as a lack of competition.” Funding, for one, is by nature a competition. Funding agencies might look at other fields and/or players to support if they deliver a higher return on investment, not only financially but also socially.

The impact of high complacency cultures can be seen in plant breeding. For instance, a rather large number of breeding programs still lack a high enough rate of what is called “elite x elite crosses.” Unless breeding pipelines run on such crosses, they achieve less than optimal genetic gains and delivery at the field. And donors get a lesser return on investment. Moreover, this complacency means not delivering the best varieties smallholder farmers need to support their families.

The parable of the slowly boiling frog is oftentimes used to portray the consequences of complacency. In any complacency-filled organization, no matter how intelligent, educated and well-intentioned its members are, change is often dead on arrival.

You may already have an inkling of what it takes to create enough urgency: bold and sometimes risk-taking leadership. For instance, some years ago, Unilever was one of the first global companies to decouple its financial growth from its environmental footprint, and it established the then outrageous sounding goal of halving its environmental footprint by 2030.

A good urgency-raising example that could inspire our line of work may be this one: let’s renew at least 50% of a current portfolio of cultivars within the next five years in a given Target Population of Environments (TPE). A second could be: let’s deploy sparse testing in at least 90% of field trials within six months.

To create urgency we need to articulate the gap between opportunities available, and the current ability of the organization to pursue such opportunities. But we must also spell out — upfront — the risks if we don’t bridge such a gap.

2. Build a guiding coalition

These days, driving change is too complex to be led by single individuals. We live in fast-paced times. And situations are full of evident and not-so-evident links among myriad moving pieces. We cannot expect one individual to be able to gather enough information fast enough, and then to consistently make the right decisions. Instead, a guiding coalition is needed, with sufficient determination, commitment and thought diversity. Such coalitions require five traits: a position of power, credibility, leadership, expertise, and individual egos held at bay. Once such teams are assembled, the main drivers of success are having a common goal, and enough trust and safety so the real issues are unearthed and addressed.

3. Develop a vision and a strategy

When leadership tries to drive change by applying dated approaches such as micromanagement or an authoritarian stance, plans are likely to fail upon arrival. These methods may breed compliance, but certainly not a fierce and sincere commitment. Because of the extreme uncertainty and organizational survival being at stake, crafting a vision plays a bigger role during change management than during business as usual.

Two main aspects of developing a vision are especially relevant to CGIAR breeding programs.

Firstly, academic and R&D organizations often keep doing what has worked well in the past. But any change management effort ought to be very explicit about what it is known as “strategic dismissal.” This is the ability to stop and phase out activities no longer providing enough value, or where the outcomes of which are not wanted/needed by funding agencies or beneficiaries. For instance, programs investing in developing hybrid cultivars for the first time in a crop could downsize previous cultivar development efforts. Alternatively, they could scale down efforts in countries that have their own strong local breeding programs. These changes are no small feat, but the inability to phase out activities clashes with the very first posit of any effective strategy: don’t just “keep doing.”

Secondly, a vision provides an invisible fabric that pulls all efforts together in a cohesive way. Therefore, its scope is much wider than most people realize, stretching across strategies, plans, and the budgets and means needed to exert change at the depth and speed needed.

4. Encourage constructive confrontation

One characteristic of a complacent organization stands out: a rather low-candor, low-confrontation culture. No one needs excessively high-confrontation, “take no prisoners”, toxic cultures. But low-confrontation cultures tend to breed under-performance, status quo maintenance and deeply ingrained complacency. And perhaps the most negative consequence is that they fail to instill a strong enough sense of ownership and accountability among its members.

Change is coming (it has arrived already…)

Yes, change is hard, but it is coming. Maybe not for drivers of right-hand drive cars. But certainly for those who want to modernize and optimize their breeding programs. Now is the time for us to invest in a smart and forward-looking change management processes.

Collaborating to accelerate genetic gains in maize and wheat

Written by Marta Millere on September 11, 2020. Posted in Features.

Stakeholders in the Accelerating Genetic Gains in Maize and Wheat for Improved Livelihoods (AGG) project have pledged to strengthen efforts to deliver desirable stress tolerant, nutritious and high-yielding maize and wheat varieties to smallholder farmers in a much shorter time. The alliance, comprising funders, national agricultural research systems (NARS), private seed companies, non-governmental organizations, the International Maize and Wheat Improvement Center (CIMMYT) and, for the maize component the International Institute for Tropical Agriculture (IITA), made these assurances during virtual events held in July and August 2020, marking the inception of the 5-year AGG project.

The initiative seeks to fast-track the development of higher-yielding, climate resilient, demand-driven, gender-responsive and nutritious seed varieties for maize and wheat, two of the world’s most important staple crops. The project is funded by the Bill & Melinda Gates Foundation, the Foreign, Commonwealth & Development Office (FCDO), the U.S. Agency for International Development (USAID), and the Foundation for Food and Agriculture Research (FFAR).

Tackling current and emerging threats

Jeff Rosichan, scientific program director of the Foundation for Food and Agricultural Research (FFAR), acknowledged the significant and ambitious aim of the project in tackling the challenges facing maize and wheat currently and in the future. “We are seeing the emergence of new pests and pathogens and viral diseases like never before. A lot of the work of this project is going to help us to tackle such challenges and to be better prepared to tackle emerging threats,” he said.

AGG builds on gains made in previous initiatives including Drought Tolerant Maize for Africa (DTMA), Improved Maize for African Soils (IMAS), Water Efficient Maize for Africa (WEMA), Stress Tolerant Maize for Africa (STMA) and Delivering Genetic Gain in Wheat (DGGW), with support from partners in 17 target countries in sub-Saharan Africa (SSA) and South Asia.

Hailu Wordofa, agricultural technology specialist at the USAID Bureau for Resilience and Food Security, underscored his expectation for CIMMYT’s global breeding program to use optimal breeding approaches and develop strong collaborative relationships with NARS partners, “from the development of product profiles to breeding, field trials and line advancement.”

Similarly, Gary Atlin, senior program officer at the Bill & Melinda Gates Foundation lauded the move toward stronger partnerships and greater emphasis on the CIMMYT and IITA breeding programs. “The technical capacity of partners has increased through the years. It is prudent to ensure that national partnerships continue. It is always a challenging environment, this time multiplied by the COVID-19 crisis, but through this collaboration, there is a greater scope to strengthen such partnerships even more,” he said.

Symbiotic partnerships with great impact

“From the NARS perspective, we are committed to doing our part as primary partners to deliver the right seed to the farmers,” said Godfrey Asea, director of the National Crops Resources Research Institute at the National Agriculture Research Organization (NARO), Uganda. “We see an opportunity to review and to use a lot of previous historical data, both in-country and regionally and to continue making improved decisions. We also reiterate our commitment and support to continuously make improvement plans in our breeding programs.”

Martin Kropff, director general of CIMMYT, recognized the tremendous impact arising from the longstanding cooperation between CIMMYT’s maize and wheat programs and national programs in countries where CIMMYT works. “A wheat study in Ethiopia showed that 90% of all the wheat grown in the country is CIMMYT-related, while an impact study for the maize program shows that 50% of the maize varieties in Africa are CIMMYT-derived. We are very proud of that – not for ourselves but for the people that we work for, the hundreds of millions of poor people and smallholder farmers who really rely on wheat and maize for their living and for their incomes,” he said.

Founder and Chief Executive Officer of East Africa-based Western Seed Company Saleem Esmail expressed optimism at the opportunities the project offers to improve livelihoods of beneficiaries. “I believe we can do this by sharing experiences and by leveraging on the impacts that this project is going to bring, from new technologies to new science approaches, particularly those that help save costs of seed production.”

He, however, observed that while the target of fast-tracking varietal turnover was great, it was a tough call, too, “because farmers are very risk averse and to change their habits requires a great deal of effort.”

On his part, director of Crop Research at the Oromia Agricultural Research Institute (OARI) in Ethiopia Tesfaye Letta revealed that from collaborative research work undertaken with CIMMYT, the institute has had access to better-quality varieties especially for wheat (bread and durum). These have helped millions of farmers to improve their productivity even as Ethiopia aims for wheat self-sufficiency by expanding wheat production under irrigation.

“We expect more support, from identifying wheat germplasm suitable for irrigation, developing disease resistant varieties and multiplying a sufficient quantity of early generation seed, to applying appropriate agronomic practices for yield improvement and organizing exposure field visits for farmers and experts,” he said.

Challenges and opportunities in a time of crisis

Alan Tollervey, head of agriculture research at Foreign, Commonwealth and Development Office (FCDO) and the UK representative to the CGIAR System Council, emphasized the need for continued investment in agricultural research to build a resilient food system that can cope with the demands and pressures of the coming decades. This way, organizations such as CIMMYT and its partners can adequately deliver products that are relevant not only to the immediate demands of poor farmers in developing countries – and the global demand for food generally – but also to address foreseen threats.

“We are at a time of intense pressure on budgets, and that is when projects are most successful, most relevant to the objectives of any organization, and most able to demonstrate a track record of delivery. CIMMYT has a long track history of being able to respond to rapidly emerging threats,” he said.

Felister Makini, the deputy director general for crops at the Kenya Agricultural Research Organization (KALRO) lauded the fact that AGG not only brings together maize and wheat breeding and optimization tools and technologies, but also considers gender and socioeconomic insights, “which will be crucial to our envisioned strategy to achieve socioeconomic change.”

Zambia Agriculture Research Organization (ZARI) maize breeder Mwansa Kabamba noted that the inclusion of extension workers will help to get buy-in from farmers especially as far as helping with adoption of the improved varieties is concerned.

In its lifecycle, the AGG project aims to reduce the breeding cycles for both maize and wheat from 5-7 years currently to 3-4 years. By 2024, at least 150,000 metric tons of certified maize seed is expected to be produced, adopted by 10 million households, planted on 6 million hectares and benefit 64 million people. It also seeks to serve over 30 million households engaged in wheat farming the target countries.

Reaching women with improved maize and wheat

Written by Marcia MacNeil on September 8, 2020. Posted in Features.

By 2050, global demand for wheat is predicted to increase by 50 percent from today’s levels and demand for maize is expected to double. Meanwhile, these profoundly important and loved crops bear incredible risks from emerging pests and diseases, diminishing water resources, limited available land and unstable weather conditions – with climate change as a constant pressure exacerbating all these stresses.

Accelerating Genetic Gains in Maize and Wheat for Improved Livelihoods (AGG) is a new 5-year project led by the International Maize and Wheat Improvement Center (CIMMYT) that brings together partners in the global science community and in national agricultural research and extension systems to accelerate the development of higher-yielding varieties of maize and wheat.

Funded by the Bill & Melinda Gates Foundation, the UK Foreign, Commonwealth & Development Office, the U.S. Agency for International Development (USAID) and the Foundation for Food and Agriculture Research (FFAR), AGG fuses innovative methods to sustainably and inclusively improve breeding efficiency and precision to produce seed varieties that are climate-resilient, pest- and disease-resistant, highly nutritious, and targeted to farmers’ specific needs.

AGG seeks to respond to the intersection of the climate emergency and gender through gender-intentional product profiles for its improved seed varieties and gender-intentional seed delivery pathways.

AGG will take into account the needs and preferences of female farmers when developing the product profiles for improved varieties of wheat and maize. This will be informed by gender-disaggregated data collection on current varieties and preferred characteristics and traits, systematic on-farm testing in target regions, and training of scientists and technicians.

To encourage female farmers to take up climate-resilient improved seeds, AGG will seek to understand the pathways by which women receive information and improved seed and the external dynamics that affect this access and will use this information to create gender-intentional solutions for increasing varietal adoption and turnover.

“Until recently, investments in seed improvement work have not actively looked in this area,” said Olaf Erenstein, Director of CIMMYT’s Socioeconomics Program at a virtual inception meeting for the project in late August 2020. Now, “it has been built in as a primary objective of AGG to focus on […] strengthening gender-intentional seed delivery systems so that we ensure a faster varietal turnover and higher adoption levels in the respective target areas.”

In the first year of the initiative, the researchers will take a deep dive into the national- and state-level frameworks and policies that might enable or influence the delivery of these new varieties to both female and male farmers. They will analyze this delivery system by mapping the seed delivery paths and studying the diverse factors that impact seed demand. By understanding their respective roles, practices, and of course, the strengths and weaknesses of the system, the researchers can diagnose issues in the delivery chain and respond accordingly.

Once this important scoping step is complete, the team will design a research plan for the following years to understand and influence the seed information networks and seed acquisition. It will be critical in this step to identify some of the challenges and opportunities on a broad scale, while also accounting for the related intra-household decision-making dynamics that could affect access to and uptake of these improved seed varieties.

“It is a primary objective of AGG to ensure gender intentionality,” said Kevin Pixley, Director of CIMMYT’s Genetic Resources Program and AGG project leader. “Often women do not have access to not only inputs but also information, and in the AGG project we are seeking to help close those gaps.”

New project to ramp up genetic gains in maize for better livelihoods

Written by Alison Doody on July 28, 2020. Posted in News.

As plant pests and diseases continue to evolve, with stresses like drought and heat intensifying, a major priority for breeders and partners is developing better stress tolerant and higher yielding varieties faster and more cost effectively.

A new project, Accelerating Genetic Gains in Maize and Wheat for Improved Livelihoods (AGG), seeks to achieve these results by speeding up genetic gains in maize and wheat breeding to deliver improved, stress resilient, nutritious seed to smallholders in 13 countries in sub-Saharan Africa (SSA) and four in South Asia. The 5-year AGG project is funded by the Bill & Melinda Gates Foundation, the UK Department for International Development (DFID), the U.S. Agency for International Development (USAID), and the Foundation for Food and Agriculture Research (FFAR).

The maize component of the project brings together diverse partners, including the International Maize and Wheat Improvement Center (CIMMYT) and the International Institute of Tropical Agriculture (IITA) as co-implementers; national agricultural research systems (NARS); and small and medium-sized (SME) seed companies.

Ambitious targets

At the inception meeting of the maize component of AGG on July 10, 2020, project leaders, partners and funders lauded the ambitious targets that aim to bolster the resilience and better the livelihoods, food and nutritional security of millions of smallholder farmers in SSA. At least 150,000 metric tons of certified seed is expected to be produced, adopted by 10 million households, planted on 6 million hectares by 2024 and benefiting 64 million people.

“We are developing climate resilient, nutritious, efficient, productive maize varieties for the farming community in sub-Saharan Africa. We will continue to work closely with our partners to develop product profiles, which are centered on the varieties that are really needed,” said CIMMYT Interim Deputy Director for Research Kevin Pixley.

AGG draws a solid foundation from previous projects such as Drought Tolerant Maize for Africa (DTMA), Improved Maize for Africa Soils (IMAS), Water Efficient Maize for Africa (WEMA) and Stress Tolerant Maize for Africa (STMA). Several high-yielding maize varieties that tolerate and/or resist diseases such as maize lethal necrosis (MLN), gray leaf spot (GLS), northern corn leaf blight, maize streak virus (MSV), turcicum leaf blight (TLB) and are drought-tolerant (DT), were developed and released to farmers across SSA. Varieties with nutritional traits such as nitrogen use efficiency (NUE) and quality protein maize (QPM) were also developed in the preceding initiatives.

A matter of “life or death”

“When farmers are confronted by aggressive farming challenges, they want products that address those challenges at the earliest opportunity. Waiting for years could mean the difference between life and death,” remarked David Chikoye, the director of Southern Africa Hub at IITA.

A key focus of AGG is to incorporate gender-intentionality – special attention to the needs of women farmers and consumers – from the traits bred into new varieties, through the communication and technology deployment strategies.

“AGG provides an excellent opportunity to reorient our maize breeding, seed scaling and delivery strategies for greater impact on the livelihoods of smallholder farmers, especially women and the disadvantaged communities that are not well reached so far,” said B.M. Prasanna, director of CIMMYT’s Global Maize Program and the CGIAR Research Program on Maize. “Our vision is to accelerate genetic gains to 1.5-2 percent annually across different breeding pipelines in the 13 participating countries in SSA and to reach over 10 million households with improved varieties.”

AGG will strengthen the capacity of partners to achieve and sustain accelerated variety replacement — or turnover — and increase genetic gains in farmers’ fields.

Old vs new

Many improved varieties have been released in the past decade. However, the turnover of old and obsolete varieties with new and improved ones is not happening as quickly as anticipated.

“We are producing good products and getting them out, but not at the speed that farmers need. How do we make it possible and profitable for seed companies to quickly introduce new hybrids?” posed Gary Atlin, program officer at the Bill & Melinda Gates Foundation. “We need to move towards a breeding and seed system where we know that we can develop a new product in 4 or 5 years and then get it to the farmers much more quickly. This is a complex problem.”

To enhance AGG’s ability to identify new products that perform well for farmers under their challenging circumstances, on-farm testing will be scaled up significantly.

Guest of honor, Ethiopia’s Minister of State for Agriculture Mandefro Nigussie, lauded CIMMYT’s support in improving the resilience and productivity of maize and wheat in the country. He observed that this has helped improve maize productivity in Ethiopia from around 2 tons/ha to about 4 tons/ha over the past two decades.

“We consider such a huge accomplishment as a combination of efforts in germplasm development and breeding efforts of CIMMYT and the Ethiopian national programs. That partnership will flourish further in this new project,” he said.

Accelerating Genetic Gains in Maize and Wheat (AGG)

Written by Rodrigo Ordóñez on July 24, 2020. Posted in Uncategorized.

Accelerating Genetic Gains in Maize and Wheat (AGG), a project led by the International Maize and Wheat Improvement Center (CIMMYT), brings together partners in the global science community and in national agricultural research and extension systems to accelerate the development of higher-yielding varieties of maize and wheat — two of the world’s most important staple crops.

Specifically focusing on supporting smallholder farmers in low- and middle-income countries, the project uses innovative methods that improve breeding efficiency and precision to produce varieties that are climate-resilient, pest- and disease-resistant, and highly nutritious, targeted to farmers’ specific needs.

The maize component of the project serves 13 target countries: Ethiopia, Kenya, Malawi, Mozambique, South Africa, Tanzania, Uganda, Zambia and Zimbabwe in eastern and southern Africa; and Benin, Ghana, Mali, and Nigeria in West Africa. The wheat component of the project serves six countries: Bangladesh, India, Nepal, and Pakistan in South Asia; and Ethiopia and Kenya in sub-Saharan Africa.

This project builds on the impact of the Delivering Genetic Gain in Wheat (DGGW) and Stress Tolerant Maize for Africa (STMA) projects.

Objectives

The project aims to accelerate the development and delivery of more productive, climate-resilient, gender-responsive, market-demanded, and nutritious maize and wheat varieties in support of sustainable agricultural transformation in sub-Saharan Africa and South Asia.

To encourage adoption of new varieties, the project works to improve equitable access, especially by women, to seed and information, as well as capacity building in breeding, disease surveillance, and seed marketing.

Funders

Project funding is provided by the Bill & Melinda Gates Foundation, the UK Foreign, Commonwealth & Development Office, the United States Agency for International Development and the Foundation for Food and Agricultural Research (FFAR).

Key partners

The primary partners for this project are the national agricultural research systems in the project target countries and, for the maize component, the International Institute for Tropical Agriculture (IITA) and small and medium enterprise (SME) seed companies.

Breaking Ground: Aparna Das leads efficient and demand-driven maize research

Written by Jérôme Bossuet on March 25, 2020. Posted in Features.

Getting a good maize harvest, or just enough to feed the family, has always been a challenge for maize small farmers in developing countries. Faced with variable rainfall, heat waves, insect attacks or diseases, they rarely yield more than two tons of maize per hectare, and sometimes lose their crops altogether. Climate change, invasive pests like fall armyworm or new diseases like maize lethal necrosis could jeopardize even further the livelihoods of maize farmers and trigger severe food crises.

In this scenario, the lives and income of maize farmers rely on good seeds: seeds that are climate-resilient, pest- and disease-resistant, and that grow and yield well under local conditions, often with minimum inputs.

“That is where the maize improvement research at the International Maize and Wheat Improvement Center (CIMMYT) plays a crucial role in this challenge of food security. You need to develop the right location-specific varieties that farmers want, that partner seed companies are willing to produce, in a cost- and time-efficient way,” says Aparna Das. She joined CIMMYT’s Global Maize research program in August 2018 as Technical Program Manager.

“My role is to work with and guide the Breeding and Seed Systems team, so that our research is more client- and product-oriented, efficient, and so that there is a better coordination and monitoring, aligned with the available resources and skills within CIMMYT, and with our numerous public and private partners,” she explains.

Value-for-money farmer impact

An important activity Das coordinated recently is a series of collaborative product profiling workshops with CIMMYT’s partners. Integrating the priorities of the national agricultural research systems and partner seed companies, this exercise reviewed and redefined what maize traits and attributes research should focus on in years to come. After this consultation, partners not only pick up CIMMYT germplasm based on trial data, but they can also verify if it fits with their own profile, to make sure that the traits they want are there. It makes breeding much more targeted and efficient.

“Product profiling has already influenced our research. For instance, all partners mentioned husk cover as a ‘must-have’ trait, because you have less insect attacks and grain spoilage,” Das explains. “Although it was considered a base trait, the breeders did not consider it systematically during their maize line selection and product advancement. Now it is integrated,” she notes.

“Our impact should not be limited to the number of varieties released or the number of papers published, but also how many varieties are picked up by partners, adopted by farmers and scaled up,” Das points out.

Breeders and seed systems specialists have worked together to estimate and track the costs of delivering products. Teams responsible for product profiles can now, through simulation, test different solutions and see what costs could be reduced or adjusted to develop the hybrid.

Das enjoys this type of collaboration. “Managing behavioral change is a key part of my role, being able to work with different teams and cultures, which makes my job so interesting,” she says.

An out-of-the-book thinker in a men’s world

Plant breeding is a male-dominated world but Das is used to fitting in as a minority. Originally from West Bengal, she grew up in Ludhiana, another Indian state and a different culture. She learned genetics and plant breeding at Punjab Agricultural University (PAU) in Ludhiana. Discovering the new field of molecular breeding, at its infancy twenty-five years ago, was an exciting challenge.

At PAU, Das pursued crop improvement research, first in wheat and potato, and later in rice genetics. She received an award from India’s Department of Science and Technology under the Young Scientist Program for her work on jumping genes in basmati rice, aimed at creating shorter and more productive basmati varieties while maintaining the basmati aroma.

Later she joined the International Rice Research Institute (IRRI) to work on the development of Golden Rice, a provitamin A-rich variety, through genetic engineering.

“Being a woman in plant breeding, especially as a breeder, is not that common. Women are not expected to do plant breeding fieldwork, away from the lab and offices. But I did not back off. I did my rice fieldwork in the paddy fields, at 40 degrees, all on my own. I believe that women bring a level of precision that is very important in breeding.”

Bridging public and private sectors

After ten years of public research, she moved to the private seed sector, to learn how seed companies integrate farmers’ needs to their research pipeline, and then channel this research to deliver to millions of farmers. “A big lesson from corporations is the value for money at each stage of their research, and that market research is instrumental to really understand farmers’ needs and guide breeding,” she notes.

After a decade in the private sector, Das was keen to move on and use her experience in the nonprofit sector. Then she joined CIMMYT. “This opportunity of technical program manager was timely. I knew the strengths of CGIAR, having highly educated scientists and the great potential outreach of the research. I knew where crop research could be improved, in converting basic research into demand-driven research.”

“Since my time at IRRI a decade ago, I realized things had moved on in the CGIAR system. Seed systems, product profiling and value chain research are now fully integrated in the Global Maize program. It is a crucial time to be here at CIMMYT. With the CGIAR reform, with the climate emergency, and emerging pests and diseases, we have to be even more inventive and reactive to continue to deliver greater impact,” she concludes.

Development of the Enterprise Breeding System well underway

Written by Sam Storr on January 29, 2020. Posted in News.

Members of the Enterprise Breeding System (EBS) advisory committee met on January 17-18, 2019, to review progress on the development of a full-spectrum breeding data management software.

CGIAR plant breeders currently rely on a suite of different software projects to make use of the data that is crucial to developing better varieties. Developed under the CGIAR Excellence in Breeding Platform (EiB), the EBS aims to provide a single solution that links data across new and existing applications so that the entire breeding data workflow — from experiment creation to analytics — can be accessed from a single user-friendly dashboard.

Development of the system is well underway, with the goal of providing a “minimum viable implementation” to pilot users at the International Maize and Wheat Improvement Center (CIMMYT) and the International Rice Research Institute (IRRI) in 2020. More advanced functions, institutions and crops will be added to the EBS over the next three years.

Working between breeders and developers to ensure needs are translated into software functions, the EBS team has trained CIMMYT staff and consultants as requirements analysts, five of whom presented to members of the EBS advisory committee the meeting on progress in the five “domains” of breeding software functions.

Sharing bits and bytes

Rosemary Shresthra introduced experiment creation, where users can quickly select the type of experiment they wish to run and automatically set up all the steps needed to complete it in the EBS.

Kate Dreher took the attendees through field implementation, where it is possible to map fields in the system and connect them to a range of plot data collection tools developed by external projects.

Ricardo León outlined the germplasm management component of the system, where the seed inventory is kept, and new entries made after trials are harvested to go on to the next stage.

Pedro Medeiros explained how an analytics request manager will allow EBS users to push their data to different analytics tools that support decision-making and, ultimately, their ability to deliver better varieties that meet farmers’ needs.

Finally, Star Gao, a breeding informatics specialist for the Genomic and Open-Source Breeding Informatics Initiative (GOBii), showed how users will be able to request phytosanitary, genotypic and quality analysis of samples from their trials through the EBS system. The system will provide an overview of the status of all samples submitted for analysis with different service providers, in addition to the ability to connect with various databases.

“We can do all this because all information in the EBS is treated the same way, from experiment creation through implementation,” said EBS coordinator Tom Hagen in summary.

The EBS advisory group, which includes user representatives from CIMMYT and IRRI breeding teams alongside EiB staff, ended the day by discussing and prioritizing new functions that could be added to the EBS over the next three years.

CIMMYT scientists join fellow experts in San Diego for world’s largest plant and animal genomics conference

Written by Alison Doody on January 21, 2020. Posted in Features.

Scientists from the International Maize and Wheat Improvement Center (CIMMYT) presented last week at the International Plant and Animal Genome Conference (PAG) in San Diego, USA.

PAG is the largest agricultural genomics meeting in the world, bringing together over 3,000 leading genetic scientists and researchers from around the world to present their research and share the latest developments in plant and animal genome projects. It provides an important opportunity for CIMMYT scientists to highlight their work translating the latest molecular research developments into wheat and maize breeding solutions for better varieties.

To meet global food demand by 2050, agricultural production must increase by 60% — while at the same time minimizing harm to the environment. This is the process of sustainable intensification, recommended by organizations like the United Nations and the EAT Lancet Commission as a key strategy for transforming our struggling global food systems.

Genomics is crucial to sustainable intensification. By studying a plant or animal’s genetic architecture, researchers can better understand what drives crop or livestock productivity, quality, climate resilience, and resistance to pests and diseases. With this information scientists can speed up efforts to develop better varieties and stay ahead of climate- and disease-related threats.

At the conference, wheat scientist Philomin Juliana shared her findings on successfully identifying significant new chromosomal regions for wheat yield and disease resistance using the full wheat genome map. Juliana and her colleagues have created a freely-available collection of genetic information and markers for more than 40,000 wheat lines which will accelerate efforts to breed superior wheat varieties. She also discussed the value of genomic and high-throughput phenotyping tools for current breeding strategies adopted by CIMMYT to develop climate-resilient wheat.

Principal scientist Sarah Hearne discussed the smarter use of genebank exploration for breeding. Germplasm banks are reserves of native plant variation representing the evolutionary history of the crops we eat. They are a vital source of genetic information, which can accelerate the development of better, more resilient crops. However, it is not easy for breeders and scientists to identify or access the genetic information they need. Using the whole genebank genotypic data, long-term climate data from the origins of the genebank seeds and novel analysis methods, Hearne and her colleagues were able to identify elite genetic breeding material for improved, climate resilient maize varieties. They are now extending this approach to test the value of these data to improve breeding programs and accelerate the development of improved crops.

Distinguished scientist Jose Crossa discussed the latest models and methods for combining phenomic and genomic information to accelerate the development of climate-resilient crop varieties. He highlighted the use of the Artificial Neural Network — a model inspired by the human brain — to model the relationship between input signals and output signals in crops. He also discussed a phenotypic and genomic selection index which can improve response to selection and expected genetic gains for all of an individual plant’s genetic traits simultaneously.

Principal scientist Kanwarpal Dhugga gave a presentation on approaches to improve resistance against maize lethal necrosis (MLN) in Africa. MLN is an aggressive disease that first appeared in Kenya in 2011, devastating maize production. It has since spread to neighboring countries. Under a grant from the Bill & Melinda Gates Foundation, Dhugga and his colleagues at CIMMYT and Corteva Agriscience have identified a small genomic region explaining more than 50% of variation in MLN resistance. They are currently validating a few candidate genes in this region. Once done, they will use gene editing directly in elite lines from eastern Africa to accelerate the development of improved, disease resistant maize hybrids.

Genomic breeder Umesh Rosyara demonstrated the genomic selection pipeline and other tools at a workshop using the online Galaxy software. Galaxy is an open-source software that allows users to access powerful computational analysis tools. The CGIAR Excellence in Breeding Platform (EiB) has set up an instance of Galaxy that contains a suite of bioinformatics analysis tools, R-packages — a free software environment for statistical computing and graphics — and visualization tools to manage routine genomic selection (GS) and genome wide association studies (GWAS) analysis. This allows crop breeders and genomic scientists without a programming background to conduct these analyses and create crop-specific workflows.

“PAG is currently the main international meeting touching both crop and livestock genomics, so it’s an invaluable chance to connect and share insights with research and breeding colleagues around the world,” said Hearne. “It’s also an important forum to highlight how we are linking upstream and field, and help others do the same.”
