Abstract

At the Research and Development Station for Viticulture and Vinification Murfatlar, in the period 2019 – 2022, was carried out clonal selection work on two cultivars for table grapes, respectively: 'Victoria' and 'Coarnă neagră'. The research consisted of the comparative study of five clonal elites of each cultivar, regarding their agrobiological and technological qualities, correlated with the specific climatic conditions of the Murfatlar vineyard. The five elites of each cultivar were studied and analyzed compared to the characters of the initial cultivar (the control). In the case of the 'Victoria' cultivar, out of the five elites under study, the one that stands out is the clonal elite ‘Victoria 57/4/7', which has great vigor, good fertility 63-73%, and high productivity. The preservability of grapes on the bush is long, about 30 days. Grape production is high, over 16-18 t/ha, of which 83-85% is commodity production. When are ripe for consumption, the grapes accumulate 140-150 g/l sugars, and the acidity is relatively low 3.8-4 g/l H2SO4. Regarding the cultivar 'Coarnă neagră', of the five elites under study, the one that stands out is the clonal elite 'Coarnă neagră’ 14/5/22', which has great vigor, high fertility, and medium ripening. The grape is large, cylindrical or cylindrical-conical in shape. Grape production is high, 20-25 t/ha, of which 85% is commodity production. The preservability on the bush is high, between 25-30 days. When are ripe for consumption, grapes accumulate 170–180 g/l sugars, and 5 g/l H2SO4 total acidity.
