Biological and technological characteristics of Georgian wine and table grapes

Georgian grapevine germplasm, which has formed for thousands of years, includes white, black, red, pink and grey 525 Vitis vinifera cultivars. In 2009–2014 up to 440 local grapevine varieties Vitis vinifera sativa has been restored. These varieties are cultivated in the LEPL Agriculture Scientific-Research Center grapevine collection GEO 038, Mtskheta Munisipal, village Jighaura, at an altitude 550 m. There are retrieved and recorded in the collection up to 60 forms of Vitis vinifera silvestris. In order to study biological and technological characteristics of Georgian grapevine, in 2012–2014 were investigated 50 Georgian widely cultivated white and colored wine and table grapes varieties, in the seven viticulture regions of Georgia. Description of grapevine varieties implemented through the descriptors for grapevine (IPGRI OIV). Botanical, biological-technological, qualitative and quantitative marks are characterized and evaluated. Investigation conducted during the biologic development phases were studied for chemical and eno-carpological characteristics
