摘要 [目的]了解不同品种葡萄对霜霉病的抗性，为鲜食葡萄的无公害生产提供理论依据。[方法]通过室内接种和田间调查研究了句容地区主要品种巨峰、夏黑、美人指、金手指、贵公子、贵公主、红乳葡萄对霜霉病的抗病性。[结果]室内试验结果表明，巨峰、贵公子、美人指、红乳对霜霉病的抗病性均表现高抗，夏黑、贵公主表现感病，金手指在室内完整叶片接种法和离体圆片接种法2种不同测定方法上表现不同的抗病性。室外调查结果表明，巨峰和夏黑多为露天栽培模式，发病率较高，其余避雨栽培品种霜霉病发病率较低，而且树龄较高的葡萄新枝发育较少，霜霉病发病率较低。[结论]根据不同葡萄品种合理设计栽培模式和修剪方式，能够防止病菌侵染，合理避过感病时期。

Abstract [Objective] The resistance of some grape species to downy mildew （Plasmop araviticola） was studied to provide theoretical basis for pollution-free production of grape. [Method] The resistance of several main grape species to downy mildew was recorded in Jurong through the indoor inoculation and field investigation. [Result] The results indoor showed that the Kyoho grape，Rosario Bianco，Manicure finger and red milk showed high resistance to downy mildew; summer black and Rosario Rosso showed susceptible resistance; gold finger showed different resistance under two different measurement methods. The investigation outdoor showed that the Kyoho grape and summer black mainly under the cultivation mode of open had higher incidence disease，and the rest of the shelter cultivars had lower downy mildew disease. The grape should get new development was less with the increase of tree age，lower incidence of downy mildew. [Conclusion] According to the different grape varieties，cultivation mode and pruning mode were designed appropriately to prevent germs infect，evade infected period and control environment factors suitably.
