Eno-carpological study of Georgian grapevine varieties from Skra germplasm repository.
2017
Eno-carpological traits were evaluated in thirty-three Georgian autochthonous grapevine varieties preserved at the Skra Germplasm repository. The standard phenotyping method proposed by the COST action FA1003 “East-West Collaboration for Grapevine Diversity Exploration and Mobilization of Adaptive Traits for Breeding” has been adopted for analyses. The obtained results showed a significant variability in the carpological and biochemical characteristics of Georgian grapevine varieties. The total phenolics for studied varieties varied from 427,7 mg/kg (Mirzaanuli Tetri (2015)) to 3378.0 mg/kg (Shonuri (2016)). The total antocyianins contents in colored grapevine varieties varied from 50.0 mg/kg to 2861.2 mg/kg, were the highest content was found in the variety Shonuri, and the lowest - in the variety Ghrubela Kartlis.
