Sorghum success

Purdue researchers have developed a variety of sorghum that is so popular with farmers in Ethiopia that they refer to it as “Purdue Sorghum,” rather than by its Ethiopian name.

A group of Purdue Agriculture faculty and graduate students saw the success of this variety first hand while attending a global meeting of the International Sorghum and Millet Collaborative Research Support Program (INTSORMIL CRSP) in Ethiopia last fall.

"This has been a bad year for many countries in Africa,” says agronomy professor Gebisa Ejeta, a member of the CRSP. “There are a number of countries with chronic food problems, and Ethiopia is one of them.” Ejeta, who is of Ethiopian descent, has been leading Purdue’s sorghum research to improve this African staple crop in ways that will keep thousands of families from going hungry this year.

There are two major problems that farmers confront in sorghum production: extremely dry weather conditions and the threat of the parasitic weed Striga. “The last 10 to 15 years, we’ve been developing unique research approaches to get a handle on the Striga problem,” says Ejeta. “We have developed sorghum varieties in our breeding program here that have high levels of resistance to Striga.”

Fields of this genetically enhanced sorghum were juxtaposed with fields of local sorghum in Ethiopia and the results were dramatic. The local crop was badly infested by Striga weeds, while the field planted with the Purdue-developed seed was Striga-free.

"The work that Gebisa has done has contributed dramatically to sorghum producers all across sub-Saharan Africa,” says David Sammons, associate dean of Purdue Agriculture and director of International Programs in Agriculture and a member of the INTSORMIL board of directors. “The varieties that he has developed are remarkable by themselves and even more remarkable if you look at them side by side with fields of other varieties.”
