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

Abstract : The genomic revolution have been the starting point for the renewal of attention on the extent of natural occurring variation in many plants species. In this regards, the use of genetic diversity in grape may greatly improve our understanding of quantitative economically important traits. Genetic resources for grape are very numerous, in particular in Europe, but the exact extent of diversity is still difficult to know. In the scope of the European GrapeGen06 project, research institutes and grapevine collections from 17 countries of Europe, Caucasus and North-Africa are working together for the characterization and management of grapevine genetic resources, including wild accessions of Vitis vinifera subsp. sylvestris. The initial work consisted of 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 project is in particular focusing on old autochthonous varieties. The database website, numbering more than 25000 accessions, is open for consultation, with different levels of access that allows in-dept 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.
