Grapevine Plant Genetic Resources-Improvement, Preservation and Biodiversity

ABSTRACTProgress in application of techniques, analyses and procedures used in EEC grapevine certification schemes are discussed. Biotechnology, virology and molecular biology as a successful approaches for genetic improvement of the existing grapevine varieties and rootstocks are also considered. Development, maintenance and evaluation of Bulgarian pre-basic grape genebank and a certification scheme related to the European Legislation appeared to be a promising step for solving the key problem for revitalisation of Bulgarian viticulture. Wild grapevines are being endangered in their natural habitats and high priorities are given to the collection and preservation of Vitis germplasms. Enlargement and unification of European Vitis database are also discussed.
