Identification and characterization of grapevine genetic resources maintained in eastern European collections

Abstract

Trabajo presentado en la Final Conference Progress in Vitis Vinifera diversity evaluation and use, celebrada en Lisboa del 7 al 9 de octubre de 2014.-- Maul, Erika et al. ; Cost action FA1003 - GRAPENET. East-West Collaboration for Grapevine Diversity Exploration and Mobilization of Adaptive Traits for Breeding. ; The Near East and in particular Caucasus region are considered as the cradle of viticulture and the area of domestication. Already in the 1920's Negrul first suggested the Caucasus as the grapevine gene centre. His perception was based on the abundantly thriving wild wines and the enormous morphologic diversity he encountered. Being both gene and domestication centre for grapevine a genetic wealth is highly expected in that area. A survey of the grapevine genetic resources present in Armenia, Azerbaijan, Georgia, Moldova, Russian Federation and Ukraine which took place from 2003 to 2007 in the scope of the project "Conservation and Sustainable Use of Grapevine Genetic Resources in the Caucasus and Northern Black Sea Region" was funded by the government of Luxembourg and managed by Bioversity. The outcome of 5 years intensive collaboration was the estimation that the maintained 2654 accessions may belong to 1283 cultivars. But trueness to type assessment by morphology and genetic fingerprinting still needed to be done. In the scope of COST Action FA1003, 1098 mainly Vitis vinifera accessions and 76 Vitis sylvestris individuals were analyzed by molecular markers. In addition to the six countries mentioned above Albania, Austria, Bulgaria, Croatia, Hungary, Lithuania, Romania, Slovakia and Slovenia participated, too. ; Peer Reviewed
