Cornell receives $25.2M funding for cassava breeding

Cassava, a rough and ready root crop that has long been the foundation of food security in Africa is finally getting the respect it deserves. The Bill & Melinda Gates Foundation and the Department for International Development of the United Kingdom (DFID) are investing $25.2 million to improve the staple crop’s productivity and build human and technical capacity for plant breeding in sub-Saharan Africa.

The five-year project is hosted by Cornell University with five partner institutions: the National Crops Resources Research Institute (NaCRRI) in Uganda, National Root Crops Research Institute (NRCRI) in Nigeria, International Institute of Tropical Agriculture (IITA) in Nigeria, Boyce Thompson Institute (BTI) for Plant Research in New York, and U.S. Department of Energy Joint Genome Institute of the Lawrence Berkeley National Laboratory, in California.

“Partners on the Next Generation Cassava Breeding project will use a state-of-the-art plant breeding approach known as genomic selection to improve cassava productivity for the 21st century,” said Ronnie Coffman, Cornell professor of plant breeding and genetics, director of International Programs, and the principal investigator on the multi-partner grant.

Cassava breeding is typically a lengthy process; it takes almost a decade to multiply and release a new variety. Genomic selection can shorten breeding cycles, provide more accurate evaluation at the seedling stage, and give plant breeders the ability to evaluate a much larger number of clones without the need to plant them in the target environment. Using genomic selection, new releases of cassava could be ready in as little as six years.

“Increased support for strengthening the research capacity in Africa and harnessing novel technologies are critical to improving overall agricultural productivity and food security for poor people,” said Yona Baguma, project coordinator for NaCRRI who aims to unlock the potential of cassava in Africa and mobilize a whole new generation of cassava growers.

“Next Generation Cassava provides a great opportunity for us to harness the power of modern science for faster delivery of best-bet cassava varieties for smallholder farmers,” said Chiedozie Egesi, assistant director at NRCRI and head of cassava breeding, who works to biofortify cassava with essential micronutrients and make it more nutritious.

Africa’s small farmers produce more than half of the world’s cassava, or about 86 million tons from over 10 million hectares. The tough woody plant is predicted to be one of the few crops that will benefit from climate change. It requires few inputs and can withstand drought, marginal soils and long-term underground storage. A cash crop as well as a subsistence crop, the storage roots of this perennial woody shrub are processed, consumed freshly boiled or raw, and eaten by people as well as animals as a low-cost source of carbohydrates. No other continent depends on cassava to feed as many people as does Africa, where 500 million people consume it daily.

In addition to using the latest genomic information from cassava sequencing to improve productivity and yield, project partners will incorporate cassava germplasm diversity from South America into African breeding programs, train the next generation of plant breeders, and improve infrastructure at African institutions. They will also hold awareness-building workshops for farmers, scholars, researchers and policy makers.
