摘　　要：采用连续回交方法,将SC316不育基因转育到中籼898品种中,研究不同世代回交群体、姊妹交群体及可育单株后代群体的育性表现。结果表明,SC316不育基因在这些群体中的表现符合1对显性核不育基因遗传规律,该不育材料携带有显性核不育基因。A male sterile gene of rice SC316 was transferred into a conventional indica rice Zhongxian 898 by consecutive backcross procedures.Genetic study on fertility was undertaken based on the anther fertility and the bagged seed setting rate of individual plant from different backcross,sibling and inbreeding populations derived from the cross of SC316 and Zhongxian 898.The results indicated that the male sterility of SC316 was controlled by one pair of nuclear dominant sterile gene.
