棉花细胞质雄性不育与育性恢复研究进展

Research Progress on Cytoplasmic Male Sterility and Fertility Restoration in Gossypium hirsutum L.

棉花细胞质雄性不育在杂种优势的利用上具有重要的作用。利用棉花细胞质雄性不育和育性恢复系统突破了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。详细阐述了棉花细胞质不育系和恢复系遗传学的研究及利用,细胞质雄性不育相关线粒体基因、育性恢复基因相连锁分子标记的开发以及恢复基因的遗传精细定位,育性相关基因的克隆等方面的研究工作,提出了存在的问题,展望了今后工作的研究方向。

Cytoplasmtic male sterile（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.This paper expounds the research and utilization of cytoplasmic male sterility and fertility genetics;the development of molecular markers linked with CMS-related mitochondrial genes and fertility restoring gene;fine mapping of fertility restoring genes and cloning of fertility-related genes.The paper also points out existing problems and prospected researched direction in the future.
