Abstract: Fertility restoration heredity of K and V (with the cytoplasm of Ae kotschyi and Ae. ventricosa respectively) types of male sterile wheat was analysed with 4 male sterile lines and 7 restorer lines. In F1, fertility restoration expressed dominance trait, and in F2 populations, the fertility segregation had polymorphism. Three male sterile lines (K83(21)35A, K149A and V149A) involved two pairs of genes, while the number of restorer gene of V83(21)35A was different in different genetic background. The fertility segregations of the same restorer lines were different in two different genetic background as K83(21)35A and V83(21)35A. The polymorphism of fertility segregation resulted from such factors as that two unit control of cytoplasmic and nuclear genome background in male sterile lines, interaction of genes, minor gene and modifing gene.
