Summary Relatively few male sterile (ms) genes have been reported in the pea despite description of numerous qualitative genes for other traits. This study was undertaken to characterize genetic male sterility in the pea. Male sterility may facilitate outcrossing because the pea is cleistogamous. Of fourteen lines carrying male sterility, tests of allelism revealed nine unique ms genes. According to F2 and F3 data, all ms genes segregated as single recessive genes. Linkage relations were determined for all but two. The genes appeared to be distributed randomly across the chromosomes. Two ms genes (ms-3 and ms-10) exhibited reduced female fertility in addition to male sterility. These mutants may have utility in increasing genetic recombination, particularly where hand hybridization is used.
