The Vitis International Variety Catalogue (VIVC) is a database of various species and varieties/cultivars of grapevine, the genus Vitis.
VIVC is administered by the Geilweilerhof Institute for Grape Breeding (Institut für Rebenzüchtung Geilweilerhof) in Siebeldingen, Germany, and contains information from grapevine collections existing in various institutes of viticulture around the world.
[3] Its initial creation was supported by the International Organisation of Vine and Wine and the International Board for Plant Genetic Resources, a forerunner of Bioversity International.
The purpose of the VIVC database is to provide documentation on available grapevine genetic resources, and to be a source of information to grape breeders, viticultural researchers and others.
The information on grape cultivars in VIVC includes basic characteristics of the cultivars, holding institutes, passport data, and all known synonyms, which are quite numerous for many grape cultivars.
