Dominant male sterile

Dominant male sterile --Marc Albertsen and M.G. Neuffer Ms41 and Ms*-7255, located on chromosome 4L, are not alleles but are linked. Because Ms41 sometimes makes small amounts of viable pollen, it was possible to cross on Ms*-7255 and obtain progeny, which when evaluated should be 1/4 double heterozygote. These individuals should be male sterile and when crossed as female by normal should give material which would provide a test for allelism. Such a test was made and the results proved that the two mutants are not alleles but are linked with 14±2cM between them. Ms*-7255 is designated as Ms44.
