选用普通小麦中3种不同生态型育性正常品种与雌性不育系XND126杂交构建3个F2组合,连续两年对3组合P1、P2、F1和F2雌性育性进行调查,利用植物数量性状主基因+多基因混合遗传模型的4世代联合分析方法分析了小麦雌性育性的遗传。结果表明:小麦雌性育性受两对主效基因+多基因联合控制,两对主效基因之间存在互作效应。 Three F2 combinations were constructed by crossing three normal ecotypes of common wheat and female sterile line XND126, and the fecundity of three combinations P1, P2, F1 and F2 were investigated for two consecutive years. Gene + polygene mixed genetic model 4 generations of joint analysis of wheat genetic inheritance of female fertility. The results showed that female fertility in wheat was controlled by two major genes plus polygenes, and there was an interaction between two major genes.
