Conservation, characterisation and management of grapevine genetic resources: the European project GrapeGen06

Abstract : Since 2007, research institutes and grapevine collections from 17 countries of Europe, Caucasus and North Africa are working together for the conservation, characterization and management of grapevine genetic resources. The initial work consisted in inventorying and describing the varieties in the partners’ collections, using standardized morphological, agronomic, and molecular descriptors, and to link the information into a unique European web-database. The growing database contains today passport data from 25.000 living accessions, of which 2.500 are linked to photos and 1.600 are characterized for 48 OIV descriptors and 9 microsatellite markers. The project is also working on 448 old autochthonous varieties that have presented a regional interest in the past but are not clearly identified. Comparing their microsatellite fingerprint with the total database will enable us to find if they are original resources and to uniquely define their traits. The database website is open for consultation, with different levels of access that allows indept searches but also confidentiality, according to the user needs. At the end of 2010, the fingerprint data will also be online, so that other collections or professionals can check their own varieties against the referenced varieties to verify names and true-to-typeness. The final objective of the European project is to promote an optimized conservation scheme of the Vitis germplasm, involving ex-situ, cryo- and on-farm conservation, so that the resources are permanently maintained, easily accessible and field-tested in a pertinent agricultural context. This network of resources will also provide plant material as a basis for biotechnology, genomic and breeding research.
