The German Genebank for Grapevine (DGR) aims to preserve the diversity of grapevine varieties in Germany in a scientific and efficient manner in the long term. The focus of conservation is on German varieties and varieties with a socio-cultural, local or historical connection to Germany. The collection also includes wild grapevine.

The German Genebank for Grapevine is a network of seven institutions maintaining grapevine collections:

•    Julius Kühn-Institute (JKI) - Federal Research Centre for Cultivated Plants

•    Federal plant variety office

•    Agricultural Public Service Centre Rheinhessen-Nahe-Hunsrück (Dienstleistungszentrum Ländlicher Raum Rheinpfalz)

•    Bayerische Landesanstalt für Weinbau und Gartenbau

•    Staatliche Lehr- und Versuchsanstalt für Wein- und Obstbau Weinsberg

•    Forschungsanstalt Geisenheim

•    Staatliches Weinbauinstitut Freiburg

Over 5,000 accessions are preserved. The Julius Kühn-Institut (JKI), Institute for grapevine breeding Geilweilerhof in Siebeldingen coordinates the network. The Institute documents DGR's genebank holdings. In addition, it supports the national and international documentation of grapevine genetic resources through the European Vitis database and the international grapevine database (Vitis International Variety Catalogue). Data on German grapevine accessions are available in the National Inventory on Plant Genetic Resources in Germany (PGRDEU).

The distribution of planting material for breeding, research and training purposes takes place via the standardised material transfer agreement (SMTA) of the International Treaty on Plant Genetic Resources for Food and Agriculture.
The Federal Office for Agriculture and Food is partner of the DGO and responsible for integration into national and international cooperation.
