用3套同核异质不育系与恢复系IR661和明恢63配组的各世代材料,分析了W,D,K型不育胞质对基因效应和育性遗传的影响。结果表明,在同核组合中,加性、加性×显性和显性×显性效应的差异较大。除加性效应外,各类基因效应估值亦有较大差异,不育胞质K与W间加性×加性和加性×显性效应、K与D间显性及加性×加性和显性×显性效应和D与W间除加性效应外的各类基因效应估值都有较大差异。汕B和K青B与IR661结合的核,其不育胞质的育性都受2对基因控制。在K17B和K青B与明恢63结合的核中,其W,D胞质亦受2对基因控制,而K胞质分别受3对和1对基因控制。在控制K胞质不育的育性基因中,有1对与W胞质和D胞质不同。
The effects of W, D, K type sterile cytoplasm on genetics and fertility inheritance were analyzed using three sets of materials of the same nuclear allogeneic sterile line and restorer lines IR661 and Minghui63. The results show that in the same nuclear combination, additive, additive × dominant and dominant × dominant effect of the larger differences. In addition to the additive effect, the estimation of various gene effects also has a greater difference between male sterile cytoplasm K and W additive × and additive × dominance effect, K and D dominance and additive × plus The dominant and dominant × dominant effects and the differences between D and W in addition to the additive effect of various types of gene effect estimates are quite different. Shan B and K green B and IR661 nuclear binding, the fertility of its sterile cytoplasm by two pairs of gene control. In K17B and K green B and Minghui 63 nuclear, W, D cytoplasm also by two pairs of genes, and K cytoplasm by three pairs and one gene control. Of the fertility genes controlling K cytoplasm, 1 pair is different from W cytoplasm and D cytoplasm.
