玉米C型细胞质雄性不育(cms)育性恢复的遗传机制尚未查清。玉米雄性不育的所有3个主要cms类型.即cms-C、cms-S和cms-T,都是由核不育恢复基因(Rf)来恢复。在cms-T的情况下,Rf1和Rf2两个显性基因,是育性恢复所需要的(Duvick等,1961;Snyder
The genetic mechanism of maize C-type cytoplasmic male sterility (CMS) fertility restoration has not been identified yet. All three major cms types of maize male sterility, cms-C, cms-S and cms-T, were recovered by the nuclear infertility restorer (Rf) gene. In the case of cms-T, two dominant genes, Rf1 and Rf2, are required for fertility restoration (Duvick et al., 1961; Snyder
