摘要
棉花具有十分明显的杂种优势,棉花细胞质雄性不育在棉花杂种优势的利用上具有重要作用。利用棉花细胞质雄性不育和育性恢复系统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。综述了近年来棉花细胞质雄性不育在细胞学、生理生化、分子生物学和育性恢复4个方面的研究进展。详细阐明了棉花细胞质雄性不育小孢子败育时期及细胞学形态、生理生化指标研究、胞内基因组和核内恢复基因的分子生物学研究和获得理想恢复系的方法,并提出了研究中存在的主要问题,展望了今后工作的研究方向。
There is fully apparent heterosis in cotton. Cytoplasmic male sterility（CMS） has played an important role in heterosis usage in cotton. CMS and utilization of fertility restorer system have made a breakthrough in conquering breeding bottleneck by artificial emasculation and unfolded a bright outlook for promoting commercial production of hybrid seed. Research progress of four facials of cytology, physiological and biochemical indexes, molecular biology and fertility restoration on CMS in Gossypium hirsutum L. during the recent years were reviewed mainly in this paper. In the four facials which were reviewed mainly in this paper,period of microspore abortion and cytological morphology,physiological and biochemical indexes including carbohydrate, amino acid, enzyme and hormone, molecular biology of intraeellnlar genome including chloroplast genome and mitochondrial genome and restoring gene in nucleus and methods of getting ideal and high resilience restorer on CMS in Gossypium hirsutum L. The objects of introducing all above these things in detail would tell peple current research status of the mechanism on CMS in Gossypium hirsutum L. and provide some helps for their relevant researches. The problems existing in the present study and the prospect to the future work on CMS in Gossypium hirsutum L. were proposed, which would provide references for related researchers.
