在培育小麦新品种工作中,与小麦产量有关的性状,绝大多数属于数量性状.而数量性状对环境条件非常敏感,它是受微效多基因控制的,在杂种后代中通常呈连续性变异,究竟是遗传的变异还是不遗传的变异,常常难以区分.而数量性状间的遗传传递能力,却又有明显的区别.王恒立等的研究 In cultivating new varieties of wheat, most of the traits associated with wheat yield are quantitative traits, while quantitative traits are very sensitive to environmental conditions and are controlled by the microscopic polygenes, and usually show continuous variation in hybrid progenies , Whether genetic variation or non-genetic variation, often difficult to distinguish between the quantitative traits of genetic transmission, but there are significant differences.Wang Hengli and other studies
