| 摘 要： | 目的]了解不同玉米品种对弯孢菌叶斑病的抗性。方法]以掖单22（感病）为对照，通过室内和田间接菌试验，研究金海5号、郑单958等11个品种对弯孢菌叶斑病的抗性差异。结果]室内接菌条件下，接菌3d后玉米开始发病，5—10d内病情发展迅速，10d后病情趋于稳定；接菌10d时，掖单22和金海5号最感病，农大108最抗病。田间接菌条件下，玉米发病症状较室内接菌严重，大部分品种表现为中感和感病，仅鲁单981、LN3和农大108表现为中抗，接菌10d后病情指数最高达76．8％，较室内接菌高36．3％。结论]对弯孢菌叶斑病抗性较好的品种为LN3和农大108，抗性较差的品种为掖单22和金海5号。

| Abstract: | Objective] The aim was to understand the disease resistance of maize varieties to Curvularia leaf spot.Method] With Yedan 22(susceptible) as CK, through indoor and field inoculation test,the resistances of 11 maize varieties such as Jinhai 5,Zhengdan 958 etc.to Curvularia leaf spot were studied.Result] Under indoor inoculation condition,maize started to infect disease after 3 d of inoculation,the disease developed quickly within 5-10 d of inoculation and the disease tended to be stable after 10 d of inoc... |
