摘要
利用质核互作雄性不育系实现强优势组合三系配套是解决目前棉花杂交制种瓶颈,促进棉花杂种优势利用的有效途径之一。本文综述了棉花质核互作雄性不育与育性恢复的研究现状,介绍了棉花质核互作雄性不育系和恢复系的类型;在细胞学和分子生物学水平上探讨了质核互作雄性不育产生的机理,阐述了育性恢复的遗传方式、恢复基因的分子标记和遗传定位、恢复基因的图位克隆及三系杂交棉的研究进展;对三系杂交棉今后的研究方向进行了展望。
Cytoplasmic-nuclear male sterility（CMS） plays an important role in crop heterosis exploitation.Utilization of CMS and fertility restorer system is an effective way to break through the bottleneck of hybrid seed production and heterosis utilization.This paper presents a review focusing on CMS and fertility restoration and their utilization,expounding the types of CMS lines and fertility restorer lines,the sterility mechanisms which were summarized from cytology,physiological and biochemical indexes and molecular basis,to fertility genetics,development of molecular markers linked with fertility restoring genes,fine mapping of fertility restoring genes and cloning of fertility-related genes.The future work on CMS and its utilization in cotton are also discussed.
