摘 要 ：通过4个具太谷核不育(Ta)小麦细胞质的回交4代可育材料与其相应核遗传组成的正常细胞质普通小麦轮回亲本品种间的正反 NCⅡ杂交(或由核遗传称为复式双列杂交),探讨 Ta 细胞质对产量等有关性状的遗传效应。试验证实两组亲本核遗传组成相对一致;Ta 细胞质与正常细胞质相比,对粒数、粒重、千粒重、结实率等性状具有不良效应;Ta
Abstract:A reciprocal NC Ⅱ mating design,the equivalent of double diallelcross mating design on the basis of nuclear genetics,between four malefertile BC_4 strains of wheat with Taigu cytoplasm and four corresponding recurrent parents with normal cytoplasm was used to evaluate thecytoplasmic effects of Taig
