一般抗性(译者注:即水平抗性)对控制植物病害的重要性已日益为人们所认识。具有微效基因的小麦品系明显具有一般抗性。早先,有关微效基因小麦品系的双列研究指出,一般抗性同高遗传力和高比例的累加基因的作用有联系。这种性状一经获得,就易于在育种方案中使用。本研究探讨在田间条件下,通过在苗期、冬小麦还在成株期进行抗性选择,企图从农艺性状过得去的冬、春小麦中得到累加的微效基因抗性。用生产品种作亲本,通常可大大减少与引进抗源相联系的不利性状。我们用抗病的、中感的同感病的春小麦进行互交,
The importance of general resistance to controlling plant diseases has become increasingly recognized. Wheat lines with a milieu gene are clearly of general resistance. Earlier, a two-line study on the wheat lines of the mildew gene indicated that the general resistance is associated with the high heritability and the high proportion of additive genes. Once acquired, this trait is easy to use in breeding programs. In this study, we investigated the resistance selection of winter wheat at the seedling stage and at adult stage in the field, in an attempt to gain additive micro-gene resistance in winter and spring wheat with agronomic traits. Producing varieties as parents can often greatly reduce the unfavorable traits associated with the introduction of sources of resistance. We use the disease-resistant, flu-susceptible spring wheat for mutual exchange,
