水稻雄性不育与杂种优势的利用

Male Sterility and Utilization of Heterosis in Rice

研究植物雄性不育尤其是农作物的雄性不育不仅有助于了解小孢子发育的生物学机理,还可以直接服务于农业生产实践.本文从模式作物水稻的角度综述了雄性不育的类型及其特征,包括细胞核不育、细胞质不育两大类型,并探讨了其形成的机理,总结了细胞质不育中育性恢复的研究进展.

Male sterility is well known in plant kingdom and it is also the basic for the utilization of heterosis,especially in crops.The researches about male sterility not only contribute the development of microspores but also to the improvement of the agricultural production directly.This review summarizes the types and characters of male sterility in rice,including genic male sterility and cytoplasmic male sterility,and recent studies about the restoration of fertility in cytoplamic male sterile rice are also discussed.
