摘　　要：纹枯病在长江流域及黄淮麦区的普遍严重发生,已成为影响小麦高产、稳产的重要限制因素,培育、推广抗纹枯病品种的前提是小麦抗病资源的鉴定和筛选。探讨了麦粒嵌入法和牙签嵌入法2种接种方法对小麦纹枯病的诱发效果,并用麦粒嵌入法分析了黄淮麦区及长江中下游麦区的小麦主栽品种、重要亲本及国外引进材料的纹枯病抗性,结果表明:带菌麦粒接种法具有更高的纹枯病接种强度,可获得更好的发病效果;所有检测品种间抗性差异明显,但高抗纹枯病的材料仅发现3份,分别为苏3/扬5、X9610和郑3666,中抗以上材料102份,占总检测材料的23.23%。Wheat Sharp eyespot （Rhizoctonia cerealis vander hoeven） has already been the main disease of wheat in the Yellow-Huai and Yangtze River valley region; it is frequently and severely occurred recently. Screening of resistant materials is the prerequisite of wheat breeding for controlling the disease. In this paper we implemented two inoculation methods, the toothpick embedding and grain embedding methods, respectively, and found the grain embedding method had better effect than that of toothpick. 439 wheat from Yellow-Huai and Yangtze River valley and CIMMITY were then inoculated by using grain embedding method, results showed that materials were different in resistant level obviously. The strategic of breeding for controlling sharp eyespot was also discussed.
