摘　　要：玉米是杂种优势利用最成功的作物之一,采用细胞质雄性不育（CMS）进行玉米杂交种生产已成为杂种优势利用的有力工具。CMS是由于细胞质和细胞核的基因表达产物的不协调而产生的不育性,可被核基因组中的恢复基因恢复。根据育性恢复专效性,玉米CMS材料主要分为T、C和S三种类型。综述了这三种类型不育及其恢复基因的研究进展,分析了在不育化制种中的应用情况。Cytoplasmic male sterility （CMS） has become a powerful tool for hybrid production in maize, which is one of the most successful crop with heterosis utilization. CMS caused by incompatibility between cytoplasmic and nuclear gene products, and the fertility canbe restored by nuclear fertility restoration （Rf）genes. Maize has three major types of CMS, namely CMS-T, CMS-S and CMS-C, on the basis ofthe reaction to specific restorers. Advance on the CMS and Rf genes of each type is reviewed, and the application situation inmaizehybrid production is analysed.
