Description of the vitis vinifera L. Phenotypic variability in eno-carpological traits by a Euro-Asiatic collaborative network among ampelographic collections

The grapevine intra-specific variability captured an increasing interest during the last decades, as demonstrated by the number of recently funded European projects focused on the grapevine biodiversity preservation. However, nowadays, crop plants are mainly characterized by genotyping methods. The present work summarizes the phenotype data collected among 20 ampelographic collections spread over 15 countries, covering most of the viticultural areas in the Euro-Asiatic region: from Portugal to Armenia and from Cyprus to Luxembourg. Together with agro-climatic characterization of the experimental site, over two years about 2,400 accessions were described. A common experimental protocol mainly focused on the carpological and oe-nological traits was followed, obtaining a general overview of the distribution of the considered phenotypic traits in the cultivated Vitis vinifera species. The most replicated cultivars were selected and, for the subset of these reference cultivars, their behavior in the different environmental conditions over sites and years was described by ANOVA methods

Progress for research of grape and wine culture in Georgia, the South Caucasus

This communication will provide the latest information about the progress of the “Research Project for the Study of Georgian Grapes and Wine Culture”, managed by the National Wine Agency of Georgia since 2014. Local and foreign institutions continue to work together with the aim of stimulating multidisciplinary scientific research activity on Georgian viticulture and viniculture and to reconstruct their development from Neolithic civilizations to the present. The project is multidisciplinary in nature, merging contributions from archaeology, history, ethnography, molecular genetics, biomolecular archaeology, palaeobotany, ampelography, enology, climatology and other scientific fields

Study of less widespread and rare Georgian wine grape varieties

The genetic biodiversity of the Georgian genome of vine is a resource that creates Georgian viticulture – winemaking basis. According to its species diversity Solomon Cholokashvili Jigaura National International Category Collection GEO 038 of Mtskheta Municiality is really very interesting. On the background of the climate global changes it is necessary to complexly re-study the less widespread and rare grape varieties – according to fenological, chemical and enocarpological characteristics, and others, to spread them on their wide range – for the purpose of diversity of entrepreneurial varieties. In addition, information received as a result of the research will be used in variety breeding, as the original material for the parent couple's target selection. The study of the species for research was performed in field and laboratory conditions by complex using of different research methods
