摘 要:以红莲型细胞质雄性不育系粤泰 A为母本与不同品种杂交 ,调查了 5 2个组合 F1 的花粉育性和小穗育性。结果表明 :这些品种对红莲型细胞质不育的恢复类型较为复杂 ,在所研究的品种中 ,只有 5 .77%的品种对红莲型细胞质不育系具有保持能力 ,其余则对红莲型细胞质不育系具有一定的恢复能力 ,这些对红莲型细胞质不育系具有恢复能力品种在恢复力上也存在一定的差异 ;就对红莲型细胞质不育系具有恢复能力品种的分布而言 ,这些品种的分布范围较广 。A “HL” type CMS line Yuetai A was used as a test variety to screen the varieties that had ability to restore the “HL” type CMS line. The results showed that there were several kinds of fertility restoration. Of 52 varieties investigated, 9 varieties were not able to restore “HL” type CMS line, the others were able to restore the “HL” type CMS line, and these varieties could also be classified into three types, according to the typical abortive, spherical abortive, stained or normal pollen grain rates of F1 plants of crosses between Yuetai A and varieties tested. The restorable varieties is widely distributed in the world.
