Mapping of Fertility Restoring Gene for Aegilops kotschyi Cytoplasmic Male Sterility in Wheat Using

<正> LK783 was found to be a good fertility restorer for K-type male sterility of wheat. Microsatel-lite markers were employed to map the major restoring gene in LK783. Maintainer and restorer DNA pools were established using the extreme sterile and fertile plants among (KJ5418A//911289/LK783)F1 population, respectively. Seventy-nine sets of SSR primers were screened for polymorphism between the two pools, 6 of which were found polymorphic. Linkage analysis showed that Xgwm11, Xgwm18, Xgwm264a and Xgwm273
