Grape is one of the most important fruit with thousands of germplasm resources and multiple genetics in the world. In recent years, with the rapid development of grape industry and internet, it was particularly important to establish a grape germplasm database in the internet. In 1984, Geilweilerhof, a grape breeding institute from Germany, was under the support of the International Organization of Vine and Wine (OIV) and Bioversity (formerly known as International Plant Genetic Resources Institute (IPGRI)), and established the most abundant grape germplasm database——VIVC (Vitis International Variety Catalogue). This paper introduces the main functions and characteristics of the VIVC in order to make the majority of grape breeders and researchers better understand the function of VIVC and a large number of grape germplasm in it, to promote the use of grape germplasm resources and innovation. This paper also reveals information regarding analysis of breeding area, utilization, color of berry skin, sex of flowers, formation of seeds, SSR-maker and other grape germplasm resource.
