Technical Abstract: An apetalous, male-sterile soybean mutant was found segregating in the F12 generation. Our objective was to register this mutant line. In other crop plants apetally mutants have been reported to be more efficient in post-anthesis photosynthesis and relocation of assimilates to the seed. In oilseed rape, apetally mutants may avoid some diseases, e.g., stem rot and downy mildew. The soybean apetally mutant is being released so that it could be tested for reaction to stem rot (syn. with white mold in soybean), and for utility as a female parent in hybrid seed production. The ultimate benefactors would be seedsmen and the farmers if the apetally trait was used commercially to reduce disease loss or if the trait could be used to produce hybrid soybean.
