小麦秆黑粉病近年在我国北方一些地区严重发生,引人注目。利用抗病品种防治该病最经济有效,但为鉴定品种抗病性创造带菌均匀的土壤条件,需大量要菌粉,而且鉴定周期很长;本研究为鉴定抗病性提供了快速方法。根据我们以往鉴定品种抗病性的结果,选较感病的品种陕合6号,测定幼苗带菌率与部位和地温的关系,选抗病性不同的品种渭麦5号、陕合6号、渭麦4号、953、F7801、西澄1号和阿勃,测定带菌率与田间
Wheat stalk powdery mildew in recent years in some areas of northern China serious occurrence, attracting attention. It is the most economical and effective to use the resistant varieties to control the disease. However, in order to identify the resistant conditions of the cultivars, it is necessary to produce a large amount of bacterial powder and the identification period is very long. This study provides a rapid method for the identification of disease resistance. According to the results of the disease resistance of our previous identification, the susceptible variety Shaanhe 6 was selected to determine the relationship between the belt-borne rate of the seedlings and the location and the soil temperature. Wemai 5 and Shanhe 6, Weimai 4, 953, F7801, Xicheng 1 and Abs, the determination of carrier rate and field
