Abstract:Vitis davidii is mainly distributed in the middle and lower reaches of the Yangtze River and south of the Yangtze River area in China. For Chinese Vitis wild species, Vitis davidii not only has larger berry size, but also presents a high resistance to anthracnose and white rot. Vitis davidii has been used as a table and wine grape cultivation in hunan, Jiangxi, Fujian, Guizhou and other regions of China. This study analyzed and reviewed the intraspecific genetic diversity of Vitis davidii, from the point of phenology, flower types, physical and chemical property, pollen morphological characters, fruit shape, DNA levels and resistance for grape species diversity. The objective of the study is to explore genetic diversity between Vitis davidii clones, which will provide a basic for protection, identification and utilization of Vitis davidii.
