Economic Characteristics of Some Newly-Selected Wine Varieties and Vine Clones in Bulgaria

During the period 1994-2008, in the Institute of Viticulture and Enology - Pleven, a comparative study of the economic characteristics of newly-selected in Bulgaria wine varieties and vine clones was carried out. It was found that according to the mechanical analysis of the grapes of the studied interspecific varieties, they were typically wine with specific characteristics of the clusters and berries suitable for the production of quality red and white wines. These varieties had high fertility rate and productivity, increased resistance to biotic and abiotic stress and were suitable to be grown on different training systems in all viticultural regions of Bulgaria. The analyzed data of many years from the grapes physico-chemical analysis of the studied clones of wine varieties showed that they were superior compared to the population of the respective variety mainly in the cluster size and mass and not so much in the berry size. The clones had a more intense rate of sugars accumulation in the grapes, while maintaining a good level of titratable acidity. The wine quality produced from the clones was better in comparison to wine from the population of the respective varieties
