摘　　要：掌握吉林省花生主栽品种(系)对花生褐斑病和网斑病的抗性及叶斑病的田间发病概况,有利于花生叶斑病的防治和品种合理布局。2017~2018年对吉林省主要栽培区域7个县市的花生叶斑病进行了田间普查,并对吉林省17个主栽品种进行了褐斑病和网斑病抗性鉴定。结果表明,吉林省花生叶斑病普遍发生,局部偏重发生、病情指数高,并有扩展趋势。抗性鉴定结果显示,主栽花生品种对褐斑病和网斑病抗性表现存在显著差异,抗网斑病品种5个,分别是吉花7号、花育23、吉花5号、双英2和99-1;抗褐斑病品种2个,吉花7号和花育23;其中吉花7号和花育23对两种叶斑病均表现出较好抗性。多数花生品种对两种叶斑病的抗性表现较差。The objective is to understand the disease occurrence and resistance to early leaf spot and web blotch of major peanut cultivars in Jilin Province.In order to provide experimental basis for disease control in the field,the peanut leaf spot investigations were conducted in 7 main peanut cultivation cities in Jilin Province from 2017 to 2018.Meanwhile the resistance of 17 peanut cultivars collected from Jilin Province to early leaf spot and web blotch were evaluated in the field.The results showed that the occurrence of peanut leaf spot disease was commonly found and serious in some areas.The disease index was high and trends to getting worse.The results of resistance evalua⁃tion showed that resistance level to peanut early leaf spot and peanut web blotch differed significantly.There were 5 cultivars resistant to peanut web blotch,including Jihua 7,Huayu 23,Jihua 5,Shuangying 2 and 99-1.There were 2 cultivars resistant to peanut early leaf spot:Jihua 7 and Huayu 23,respectively.Jihua 7 and Huayu 23 were resistant to peanut early leaf spot and peanut web blotch.The rest peanut cultivars were susceptible to these two leaf spot diseases.
