Purdue University professor Gebisa Ejeta has received a $5 million grant from the Bill & Melinda Gates Foundation to help develop hybrid grain seeds that will resist parasite weeds.

Purdue University scientists will develop stronger, more versatile varieties of sorghum that have the potential to reach millions of African farmers, thanks to a $5 million, five-year grant from the Bill & Melinda Gates Foundation. Ejeta, the 2009 World Food Prize laureate, was recognized for his work in developing and distributing high-yielding varieties of sorghum that are also drought-tolerant and resistant to striga, a parasitic weed that robs maize, sorghum, rice, pearl millet and sugarcane of necessary nutrients. Striga can devastate a crop and impacts more than 100 million people in Africa. Over the last four years, Ejeta, along with his students and research collaborators, uncovered the basic genetic and biological processes that control striga resistance in sorghum. They identified a gene involved with the release of a chemical from sorghum roots that signals striga seed to germinate and attach to those roots. That has led to the creation of new sorghum varieties that combine striga- and drought-resistance more readily using molecular technology. So far, 961 tons of seed have been distributed to more than 400,000 farmers in Ethiopia and Tanzania. This next phase of the program will focus on advancements in biological research, specifically identifying more genes involved in imparting broad-based and durable striga resistance in sorghum and other crops. The new project will expand to support researchers in Tanzania, Kenya, Rwanda, Sudan, Niger, Nigeria, Burkina Faso and Mali to develop a breeding pipeline for more high-yielding, nutritious, disease-resistant and drought-tolerant varieties of crops. “This creates opportunities for farmers and small businesses to engage in gainful employment and develop the agricultural industry in these countries,” Ejeta said.
