摘　　要：分析了 2个早稻恢复系 (R4 0 2和测 4 8- 2 )对水稻矮败型细胞质雄性不育恢复性的遗传。结果表明 ,恢复系 R4 0 2中存在一对显性恢复基因 R1R1;而测 4 8- 2中有两对显性恢复基因 R1R1R2 R2 ,R1和 R2 间表现显性上位作用。追溯恢复基因 R1和 R2 的来源 ,它们分别来自我国晚籼品种仙那和印度品种 SL O17。Inheritance of restoring genes was analyzed for two restorer lines R 402 and Ce48 2 of early rice. The results showed that the restoring ability of R402 was controlled by one pair of dominant gene R 1R 1, and that of CE48 2 by tw o R 1R 1R 2R 2, one is epistatic to the other. Ascending the source of rest oring gen es R 1 and R 2, they were derived from late indica variety Xian na in Chi na and variety SLO 17 in India respectively.
