【摘要】 利用４个不育系与７个恢复系对Ｋ、Ｖ型不育系育性恢复遗传进行了分析。结果表明，Ｆ１育性恢复表现为显性遗传，Ｆ２群体育性分离呈现多态性。Ｋ８３（２１）３５Ａ、Ｋ１４９Ａ、Ｖ１４９Ａ三个不育系的育性恢复均受两对基因控制，Ｖ８３（２１）３５Ａ的育性恢复所需基因数目在不同遗传背景中不同。同一恢复系在Ｋ８３（２１）３５Ａ和Ｖ８３（２１）３５Ａ两种不同遗传背景中表现不同的育性分离。分析Ｆ２育性分离多态性的原因，认为主要与不育系本身细胞质和细胞核基因组的双元调控、微效基因、修饰基因以及基因间互作等遗传因素有关更多还原

【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 F 1, fertility restoration expressed dominance trait, and in F 2 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.更多还原
