用Ｃ组的ＣⅠ和ＣⅢ亚组不育胞质的５个不育系和２个恢复系为材料，以１７个涉及第９染色体和不同染色体臂的糯粒易位系为工具，测定了恢复主基因在染色体上的位置。试验结果表明，恢复系Ａ６１９和广１０２携带１对恢复主基因，位于第７染色体长臂外端，与易位系Ｔ７９ａ的断点连锁，它能恢复ＣⅠ和ＣⅢ亚组胞质不育的花粉育性。还讨论了Ｃ组不同亚组胞质不育的恢复性反应和恢复性遗传的复杂性。 Five CMS lines and two restorer lines of CⅠ and CⅢ subgroups of C group were used as materials and 17 waxy grain translocation lines involving chromosome 9 and different chromosome arms were used as tools to measure the recovery The location of the major gene on the chromosome. The results showed that the restorer line A619 and Guang 102 carried one pair of restorer major genes located at the outer end of the long arm of chromosome 7 and linked with the breakpoint of the translocation line T79a and restored the cytoplasm of CⅠ and CⅢ subgroups Sterile pollen fertility. Also discussed in the C subgroup of different cytoplasmic sterility recovery response and recovery of genetic complexity.
