摘要
用 8个蛋白含量不同的小麦品种配成 NC 设计杂交组合 ,对籽粒蛋白质及其组分含量进行数量遗传分析表明 ,小麦籽粒蛋白及其组分含量在品种间表现有一定的差异 ,籽粒蛋白含量、醇溶蛋白含量、谷蛋白含量主要受加性效应控制 ,清蛋白含量、球蛋白含量主要受非加性效应控制 ;不同亲本不同组合的 GCA和 SCA差异较大 ,在小麦优质育种中应以高蛋白材料作为亲本之一 ,选配组合时最好采用高×高类型或高×低类型 ;在中亲优势测定中 ,除醇溶蛋白表现为正向超亲外 。
The quantitative inheritance analysis of NCⅡ mating design of eight wheat varie ties with different protein content shows that the protein contents of seed, the content of prolamine and gluteline are ma inly controlled by additive effect while the content of albumin and glbuline is mainly controlled by non additive effect. The GCA of different parents and the SCA of different combinations of the content of protein and its components have much difference. High protein variety should be selected as one of parents durin g quality breeding. While combinations are chosen, high×high type or high×low type is better. On the test of heterosis over the average of its parents, all ch aracters show negative heterosis except prolamine.
