Abstract

The use of genetic male sterility to facilitate recurrent selection in soybeans has been discussed by Brim and Stuber (1973), Fehr and Ortiz (1975), Kenworthy and Brim (1979) and Brim and Burton (1979). A problem with the selection schemes that have been presented is the occurrence of male- sterile segregates in the yield-test plots and the consequent reduction of precision in measuring yield. In the proposed scheme (Table 1), male sterility is employed to recombine selected lines, but tested material consists of homozygous fertile plants.
