Gebisa Ejeta
Encyclopedia
Gebisa Ejeta is an Oromo American plant breeder, geneticist and Professor at Purdue University
. In 2009, he won the World Food Prize
for his major contributions in the production of sorghum
.
. The university and the U.S. Agency for International Development helped him earn a doctorate from Purdue.
Working in Sudan
during the early 1980s, Ejeta developed Africa's first commercial hybrid variety of sorghum tolerant to drought. Later, with a Purdue University
colleague in Indiana, he discovered the chemical basis of the relationship between the deadly parasitic weed striga and sorghum, and was able to produce sorghum varieties resistant to both drought and striga.

for his major contributions in the production of sorghum
Sorghum
Sorghum is a genus of numerous species of grasses, one of which is raised for grain and many of which are used as fodder plants either cultivated or as part of pasture. The plants are cultivated in warmer climates worldwide. Species are native to tropical and subtropical regions of all continents...

Early years
During primary school, Ejeta planned to study engineering when he reached college age, but his mother convinced him he could do more working in agriculture. With aid from Oklahoma State University, he attended an agriculture and technical secondary school in Oromia-Ethiopia and also studied at what is now Jimma UniversityJimma University
Jimma University is one of the top teaching universities in Ethiopia, and is located in Oromia Region, Jimma Zone. It offers programs and researches which lead toward degrees in different fields of studies. It was established in December 1999 with the amalgamation of the Jimma College of...
