本文研究了原产我国的葡萄属19个种和变种、82个株系对霜霉病的抗性。结果表明,不同种对霜霉病的抗性存在很大差异。抗病的种或变种有:华东葡萄、瘤枝葡萄、复叶葡萄、秋葡萄、葛(?)、华北葡萄、燕山葡萄和菱状葡萄;感病的种或变种有:网脉葡萄、毛葡萄、山葡萄、刺葡萄、蘡(?)、三出葡萄、桦叶葡萄、小叶葛(?)、麦黄葡萄、秦巴野葡萄和米葡萄。 华东葡萄、刺葡萄、秦巴野葡萄和米葡萄种内不同株系对霜霉病的抗性变异不大。而瘤枝葡萄、复叶葡萄、秋葡萄、山葡萄、燕山葡萄和华北葡萄等种内不同株系间抗性差异很大,有抗病和感病两种类型。并且抗病类型的分布似与地理起源无关。
In this paper, 19 species and varieties of Vitis originating from China were studied, and 82 lines were resistant to downy mildew. The results show that different species of resistance to downy mildew there is a big difference. The disease-resistant species or varieties are: East China grapes, knobgrass grapes, compound leaf grapes, autumn grapes, Ge (?), North China grapes, Yanshan grapes and rhombic grapes; susceptible varieties or varieties are: Grapes, mountain grapes, prickly grapes, raisins (?), Three grapes, birch leaves, small leaf Ge (?), Wheat yellow grapes, Qinba wild grapes and rice grapes. Huadong grapes, prickly grapes, Qinba wild grapes and rice varieties of different strains of resistance to downy mildew little variation. However, there are two types of disease resistance and susceptibility among the different strains within the branches, grapevine, the compound leaf grape, the autumn grape, the grape of the mountain, the grape of Yanshan and the grape of North China. And the distribution of disease-resistant type seems to have nothing to do with the geographical origin.
