| 摘 要： | 采用国内指标法和国际指标法对豫麦３号雄性不育系育性恢复性能进行了研究。结果表明，１６３个恢复系间的恢复主差异显著，国内法恢复度超过８０％的恢复系占１１．６３％；Ｋ型杂种小麦小穗中部小花的结实性与恢复系的恢复能力呈高度正相关。

Study on the Fertility Restoration of Male Sterility in Wheat with Ae.kotschyi Cytoplasm |

| Abstract: | The significant difference in restoring ability calculated by international method and domestic method was found among the hybrids between male sterile line Yumai 3 with Ae.kotschyi cytoplasm MS(K) Yumai 3] and 163 restoring lines.The restoring degree of 19 lines,which was calculated by the domestic method,is in access of 80 percent.The seed set rate of central florets of spikelets for the hybrids with Ae.kotschyi cytoplasm was significantly positively correlated with the restoring ability of restoring lines,the correlation coefficient between them was 0.977 5.The study on the distribution of restoring and the segregation of fertility restoration of F 2 population for the 3 hybrids between MS(K) Yumai 3 and 3 R lines was continuously conducted for two years.The results indicated that one R line with higher restoring ability might possess 3 pairs of restoring genes,and the two others might possess 2 pairs of restoring genes.The restoring ability calculated by international method was normally distributed,and the higher the restoring ability is,the smaller the distribution variance will be. |
