One of the M3 progenies of Type-49 soybean irradiated with 15 kr gamma rays showed segregation for plants with abnormal flowers. The progeny consisted of 30 normal plants and 8 mutant plants, indicating a monogenic inheritance. The mutant plants set only a few pods and appeared almost sterile at maturity.
