A partially male sterile strain of soybeans, Glycine max (L.) Merrill, was found in Arkansas in 1964. Grafts involving partially sterile and fertile plants indicated that this character likely was genetically controlled. Only 5 to 10% of pollen from the partially sterile strain appeared to be viable when stained with aceto‐carmine and glycerine. Plants of the F~ generation from a cross between a partially sterile and a fertile strain were completely fertile. Segregation occurred in the F~o generation and gave further evidence for dominance of fertility over partial sterility. Natural cross‐pollination estimates of 11.21% and 0.26% were obtained for the partially sterile and fertile strains, respectively.
