小麦白粉病现已成为全国性甚至世界性主要病害之一，也是目前宁夏小麦生产的主要病害。通过开展宁夏主栽和新培育25份优质春小麦品种（系）白粉病在苗期和成株期田间自然发病和诱发发病的调查分析，了解宁夏主栽和新选育春小麦品种（系）抗病性。结果表明：宁夏现阶段主栽和推广品种（系）多数不抗白粉病。苗期表现高抗的品种（系）主要有11MJ557、11MJ555、M6553、11M1243，中抗品种（系）主要有12MJ376、H4670、N618；成株期仅有11MJ557和N618表现中度抗病，且在不同地区发病程度表现略有差异。建议加强11MJ557、11MJ555、N618、12MJ376等小麦品种（系）的试验示范力度，力求生产上尽早推广应用，在科研上也可作为优异种质资源创新利用。

Wheat powdery mildew has become one of the main diseases nationally and even worldwide, it's also the main disease in the wheat production in Ningxia at present. By carrying out an investigation and analysis of the natural and in-duced powdery mildew diseases in the seedling stage and adult stage of the major wheat cultivars and 25 groups of new-ly-bred high-quality spring wheat varieties (lines) in Ningxia, the disease resistances of the major cultivars and the new-ly-bred spring wheat varieties in Ningxia were known. The results showed that most of the major cultivars and widespread wheat varieties (lines) in Ningxia could not resist the powdery mildew. At seedling stage, the varieties such as 11MJ557, 11MJ555, M6553, 11M1243 showed a high resistance to powdery mildew, the 12MJ376, H4670, N618 showed a middle re-sistance to powdery mildew. At adult-plant stage, there were just 11MJ557 and N618 showed a middle resistance to powdery mildew, and the degree of disease in different areas showed a slight difference. It is proposed that the experimental demon-stration of the wheat varieties of 11MJ557, 11MJ555, N618 and 12MJ376 should be strengthened and efforts should be made to popularize and apply them in the production as soon as possible, and they also can be used as excellent resources in scientific research.
