| 摘 要： | 对20个玉米品种进行了抗弯孢霉叶斑病研究,结果表明,不同玉米品种对弯孢霉叶斑病存在着一定的抗病性差异。其中中感品种为先行3号,病情指数为15.52%;高抗品种为富友1号和振杰2号,其余的品种皆为中抗。除此之外,还分析了影响玉米弯孢霉叶斑病发生的因素,其发病程度除受品种抗病性等因素的影响外,主要取决于8月中、下旬的降雨日和降雨量。

| Abstract: | Experimental results of 20 corn cultivars suggested that the 20 cultivars showed certainly difference of resistance.Xianxing 3 was middle sensitive to the disease with 15.52% of infection index,Fuyou1 and Zhenjie 2 were high resistant to the disease,the rest all showed middle resistance.In addition,the raining days and rainfall amount of the middle or last ten days in August were important factors effecting corn curvalaria leaf spot. |
