摘　　要：水稻细胞质雄性不育系由于农艺性状不够优良,很少在育种中得到利用,但细胞质雄性不育系具易引进和易获得杂交种子的特性,利用合理的育种策略,细胞质雄性不育系能在三系保持系、三系恢复系及常规稻品种选育中得到广泛利用,包括通过细胞质雄性不育系培育近等不育系进而选育三系保持系,通过细胞质雄性不育系引进粳稻血缘选育三系恢复系及常规稻品种。介绍了水稻细胞质雄性不育系相关育种情况并展望了其利用前景。CMS line is seldom used in rice breeding for its fair agronomic traits, but CMS line has such available characteristics as being attainable and being easy to get hybrid, reasonable breeding strategy can make CMS line used in many rice breeding programs, including developing maintainer line by the way of development of near-isogenic line of CMS line, developing restorer line and inbred variety as a bridge to introduce japonica rice into indicia rice. The concerned breeding progress was introduced and the prospect was viewed.
