Abstract: 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.

Key words: cotton, male sterility, heterosis
