前言小麦白粉病(Erysiphe graminis f.sp.tritici)是大部分麦区发生较重的病害,选育抗白粉病的品种是小麦高产稳产的有效保证。研究抗源的抗性遗传规律,是抗病育种的重要组成部分。据报道,小麦抗白粉病性的遗传主要是单显性遗传,也发现单隐性遗传和双显性基因重叠作用控制的遗传。国内一些单位采
Introduction Erysiphe graminis f.sp. tritici is a serious disease in most of the wheat regions. Breeding of powdery mildew resistant varieties is an effective guarantee for high and stable yield of wheat. Studying the genetic law of resistance to resistance is an important part of disease resistance breeding. It has been reported that the inheritance of resistance to powdery mildew in wheat is dominated by heritable inheritance, and the inheritance of single-recessive inheritance and double-dominant gene overlap control is also found.
