Interpretive Summary:

Technical Abstract: Utilizing the linkage between one of the 2 recessive genes controlling green cotyledon in soybeans (d1d1 or d2d2) and the males sterile gene, ms5, it was possible to develop uniformly male sterile seed lots to use for planting the female rows in a hybrid seed production field. Blends versus separate rows for the male fertile and male sterile plants and different ratios of male sterile to male fertile plants were compared for the amount of hybrid seed produced on the male sterile plants. Blends resulted in consistently more hybrid seed production. The ratio of male sterile to male fertile plants was dependent on the genotypes of the male sterile and male fertile plants.
