Contract period: 01.07.2017 - 30.06.2019
Purpose of research: Applied research
Keywords: genetic resources in grapevine, breeding

Armenia possesses a high diversity of local autochthonous cultivars and huge populations of the wild grape Vitis sylvestris. In this project, one of the main concerns is the safeguard of Armenian grapevine genetic diversity. In this context the major goals are the collection of the still existing diversity, its comprehensive description, genotyping and evaluation and the effective management of the two germplasm collections in the country. In the early 1990s, the central collection of Armenia with 22 ha and 850 varieties was destroyed. In one of the new ampelographic collections (Etchmiadzin, Armavir region) about 270 varieties are preserved. The maintenance of grape germplasm requires documentation via multi crop passport data (Multi Crop Passport Descriptor List of Bioversity) and characterization of each accession via 48 characteristics of the OIV descriptor list for grape cultivars and Vitis species (http://www.euvitis. de/docs/descriptors/mcpd/Code_descripteurs_2ed_EN.pdf). For ascertainment of trueness to type the use of nuclear microsatellites proved to be particularly suitable for the comparison of allelic data between different international collections. In the present project a multidisciplinary study will be carried out to identify valuable grape genetic resources, with high wine and table grape quality and possibly with resistance to abiotic stresses and fungus diseases. Within that context fourteen molecular markers will be analyzed. Another goal is a comprehensive evaluation of the polyphenol content in grape berries, because these secondary metabolites are considered as free radical scavengers. All accession specific data produced within the project will be uploaded in the European Vitis Database and thus will be made available for research, breeding and winegrowers.
