| 摘 要： | 各农艺性状的遗传变异中加性主效应、显性主效应均起一定的作用,株高主要受加性主效应的控制,株高的狭义遗传力为50.8%,通过早代选择可取得较好的改良效果,其选择效果不易受到环境条件变化的影响;蛋白质和脂肪含量主要受加性主效应的控制,其狭义遗传率分别为66.3%和64.2%,宜在较低世代进行选择;异黄酮含量主要受显性主效应的控制,应该在较高世代进行选择。

| Abstract: | Additive and dominant effects both play certain roles in the inheritance and variation of the agronomic traits measured.Plant height was mainly controlled by additive main effects.Because heritability in the narrow sense of plant height was 50.8%,the trait could be improved by selecting in early generations and the improved effects were stable environmentally;Additive and dominant effects both play roles in the inheritance and variation of the content protein and oil,whose heritability in the narrow sense w... |
