近年来,小麦白粉病在我国各地麦区普遍发生。研究明确主要抗白粉病品种的抗性遗传表现,促进和提高抗白粉病小麦育种工作的效能,是一项亟待开展的工作。国外在这方面的成果很多,对许多小麦品种的抗白粉病遗传特性有所了解,已经确定了10多个抗白粉基因,在育成抗白粉病小麦品种的工作中起到了重要的作用。国内对此研究较少。经验表明,小麦品种抗白粉病遗传比较复杂,因品种由来的抗源、品种相与交配的组合而不同。据贵州农学院1979以来的研究,白免三号具一个显性抗性基因;高加
In recent years, wheat powdery mildew occurred throughout the wheat area in our country. It is an urgent task to study the genetic manifestations of the resistance of the major powdery mildew resistant cultivars and to promote and enhance the efficiency of wheat breeding against powdery mildew. Many foreign achievements in this area, many of the wheat varieties resistant to powdery mildew genetic properties have been understanding that more than 10 anti-white powder genes have been identified in the breeding of powdery mildew resistant wheat varieties have played an important role. Domestic research on this less. Experience has shown that the resistance of wheat cultivars to powdery mildew is rather complicated and varies depending on the origin of the cultivars, the combination of the phases and the mating. According to the research since Guizhou Agricultural College in 1979, Baijiao 3 has a dominant resistance gene;
