摘要： 质量-数量性状是指具有主基因效应的数量性状,它在作物的许多重要经济性状中均有存在.这种性状可能同时受主基因和多基因控制,但迄今相应的遗传分析方法.本文分析了主基因为一个位点时质量-数量性状的世代遗传组成.结果表明,如果能够区别分离世代中的各种主基因基因型,就能对这种性状是否存在主基因和/或多基因效应作出有效的

关键词: 质量-数量性状,主基因,多基因,遗传组成.

Abstract: Qualiative-quantitative traits,a bbreviated to Q-Q traits,refer to quantitative traits with major gene effects. They have been found in many important characters,such as plant height,resistance to diseases and insects, grain quality and hybrid fertility in crops,The Q-Q traits may be controlled simu
