Gebisa Ejeta (born 1950) is an Ethiopian-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.
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 Haramaya University. 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.
