土传病害茄子大丽轮枝菌致病类型的研究

Study on Pathogenic Types of Verticillium Dahliae kleb for Soil Borne Diseases

将天津市５个地区采集的２０个茄子黄萎病致病菌——大丽轮枝菌菌株，在６个茄子品种上做致病类型的测定。结果表明，各菌株的致病力可分为强、中、弱３个类型；明确了天津市３个茄子主栽品种的抗感反应型：快圆茄为感病型，大苠茄为中感型。

The pathogeny of eggplant verticillium wilt,20 strains of verticillium dahliae kleb,are collected from five areas in Tianjin.We used six varieties of eggplant to determine pathogenic types of 20 strains.The result showed that different strains had difference ability to cause diseases,which had three pathogenic types are strong,middle and weak.We also made definite the types of reaction about three main cultivars of eggplant in Tianjin,the Kuai Yuan is sensitive ,the Da Min is middle sensitive,the Er Min is resistant.
