提高育种效率,有赖于对有关性状遗传本质的了解。多数研究表明,小麦品质性状,其中包括蛋白质和赖氨酸含量,是由微效多基因系统控制的。其基因效应主要是加性;在非加性中主要是部分显性,但也发现有超显性。 Improving breeding efficiency depends on an understanding of the genetic nature of the trait. Most studies show that wheat quality traits, including protein and lysine content, are controlled by the microscopic polygenic system. The gene effect is mainly additive; in non-additive is mainly dominant, but also found super-dominant.
