摘　　要：棉花在产量、品质、生理生化特性等不同的性状上均具有明显的杂种优势。棉花雄性不育在棉花杂种优势的利用上具有重要作用,棉花雄性不育可以突破传统人工去雄杂交育种的瓶颈,为棉花杂交种制种的商业化推广展现了光明的前景。综合目前棉花雄性不育的研究成果,本文介绍了棉花雄性不育系的类型,综述了其细胞学特征、分子机理,以及相应培育方法,同时分析了目前存在的问题,并对雄性不育系的应用前景进行了展望。There is fully apparent heterosis in cotton, showing on the production, quality and physiological characteristics of cotton. The male sterility on cotton has played an important role in heterosis usage in cotton. Utilization of the male sterile system have made a breakthrough in conquering breeding bottleneck by artificial emasculation and unfolded a bright outlook for promoting commercial production of hybrid seed. This paper reviewed the major advances of biological research on the male sterility in cotton in the past decade; focused on the types, cytological features, mechanisms and breeding method of male sterile cotton; analyzed the existed problems; and maked prospects of male sterility applications.
