摘要
回顾了水稻籼型不育系选育的历史,分别从新质源发掘及利用、不育系选育方法的创新以及"广亲和"理论的应用3个方面阐述了水稻籼型不育系的研究现状,并指出籼型不育系选育存在综合性状水平低、光温敏核不育系配合力低、两系法制种不安全等问题。最后从3个方面,即提高籼型不育系的综合性状,选育高配合力的两系不育系以及解决两系不育系安全制种技术问题,并展望了籼型不育系的育种前景。
The breeding history of indica sterile line in rice is briefly reviewed. The research status of indica sterile line is described from three aspects as follows： the excavation and application of new cytoplasmic source, the innovation of breeding method in sterile line and the application of＂wide compatibility＂theory. The author considered the probable problems in the breeding process, such as the comprehensive characters level of sterile line is low, combining ability of photo-thermo-sensitive genic sterile line is lower, and the seed production of two-line hybrid rice is not safe. According to the problems mentioned above, the author proposed some sugges-tions for the breeding of indica sterile line in the future.
