Professor
Soybean Breeding, Genetics

Soybean Breeding Website

Soybean production research aids farmers in becoming more profitable. The program works to develop both non-GMO and GMO soybean varieties for the general-use and specialty-export markets, and also to test private company varieties to aid farmers in choosing the best variety for their farm.
