果树种质资源的调查与研究,对于开发利用资源、选育新品种、发展现代化果树生产,探讨果树分布、分类、起源、演化等均具有重要意义。葡萄是世界上栽培面积最大、产量最多的果树,葡萄种质资源的研究,已引起国际上的重视。1982年在巴黎举行的国际葡萄栽培和葡萄酒协会第62届年会上,讨论的中心议题就是葡萄种质资源的收集、保存和开发利用问题。我国是野生葡萄起源中心之一,世界葡萄属植物近70种,东亚类群有40个种,原产我国的就有35个种。对野生葡 The investigation and research of fruit tree germplasm resources are of great significance for developing and utilizing resources, breeding new varieties, developing modern fruit tree production, exploring the distribution, classification, origin and evolution of fruit trees. Grape is the world’s largest cultivated area, the largest production of fruit trees, grape germplasm resources research, has attracted international attention. At the 62nd Annual Conference of the International Viticulture and Wine Association, held in Paris in 1982, the central topic of discussion was the collection, conservation and exploitation of grape germplasm resources. China is one of the centers of origin of wild grapes. There are nearly 70 species of Vitis in the world, 40 species in East Asia and 35 species in China. To wild Portuguese
