霜霉病是葡萄的一种世界性病害,它的研究从十九世纪末期就已开始。为了进行葡萄霜霉病的抗病育种,我们对葡萄霜霉病抗病性鉴定的方法进行了初步的探讨。同时研究了原产我国的葡萄属野生种对霜霉病的抗性,以期找出抗病性的材料,用于今后的抗病育种。试验于1983—1984年在西北农业大学葡萄园进行。所用材料有:欧洲葡萄、河岸葡 Downy mildew is a worldwide disease of grapes and its research has begun since the late nineteenth century. In order to carry out resistance breeding of grape downy mildew, we conducted a preliminary study on the identification of grape downy mildew disease resistance. At the same time, we studied the resistance of the wild Vitis species in China to downy mildew in order to find out the disease-resistant materials for future disease-resistant breeding. The experiment was conducted at the Northwest Agricultural University Vineyard from 1983 to 1984. The materials used are: European grape, river bank Portuguese
