Mutant T251 was found by Dr. R. L. Bernard at the University of Illinois in an F2 progeny from the cross 'Harosoy'5xT139. (Tl39 is a yellow mutant found in 'Illini' in 1936.) T251 is maintained in the Soybean Genetic Type Collection as the heterozygote T251H because of its low seed set. It is char-acterized by its short and slender stature.
