Abstract: The methodology of developing nuclear male-sterile line and its usage in cotton were reviewed in the paper. There were 17 kinds of nuclear male-sterile lines that were developed through different methods including selecting from mutants, artificial induction, genetic improvement and creating by biological technique. With male sterility (ms14 and ms5ms6) applied to cotton breeding, 28 hybrid varieties were bred in China. The research on production of hybrid seeds and marker of male sterility was also summarized. It is proposed that the key of extending utilization of male sterility is to break through in creating marked male-sterile lines, and assistant castration by manual work is efficiency in currently production of nuclear male-sterile hybrid seeds.
