The “U.S.D.A.”, Brazilian, Vg, and Reid male steriles were not greatly different in cytoplasmic-genotypic interactions involved in expression of male sterility. The Texas type differed from the others studied. Modifier genes in an inbred line background appeared to influence expression of male sterility more in the “U.S.D.A.” type than in the Texas type. A degree of selective fertilization occurred in plants bearing either the Vg or Reid cytoplasmic factor and heterozygous for the fertility restoring gene(s) from inbred line Ky 21.
