刺葡萄种内遗传多样性研究进展

Intraspecies Genetic Diversity of Vitis davidii

刺萄萄主要分布在我国长江中下游及以南地区,是中国野生萄萄中果粒最大的一个种,其果实高抗炭疽病和白腐病,在湖南、江西、福建、贵州等省的部分地区一直作为鲜食和酿酒品种栽培利用。刺葡萄种内遗传多样性较为丰富,为了充分挖掘利用刺葡萄资源,提高刺葡萄资源的利用效率,本文从刺葡萄的物候学、花器类型、形态性状、果实理化性状、花粉形态、DNA遗传水平和抗性等方面进行种内多样性的研究和综述,以期为刺葡萄种质资源的保护、鉴定评价和发掘利用奠定基础。

Vitis davidii is mainly distributed in the middle and lower reaches of the Yangtze River and south of the Yangtze River area in China. As one of the wild Vitis species originated in China, 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. These results will provide a basic for protection, identification and utilization of Vitis davidii.
