Main behavior of vine varierieties with biological resistance in the south romanian climatic conditions were analyzed during 3 years of study. Thus they was determined: phenology varieties, fertility and productivity for table and wine varieties, behavior of these varieties at the main attack of major diseases and pests attack, physico-mechanical characteristics, the technological attributes of varieties, the physico-chemical characteristics of wines. For content of grapes in volatile compounds was used the gas chromatography/mass spectrometry method. The wine varieties studied were: 'Moldova' and 'Andrevit' (table wine varieties), 'Admira', 'Radames' and 'Brumariu' (varieties of wine).In ecopedoclimatic terms from the southern Romania, varieties mature later, in maturation ages IV ('Andrevit', V ('Admira') and VI ('Moldova', 'Radames' and 'Brumariu'). From the point of view of fertility and productivity varieties, variety Admira had the best behavior, also the same variety with the table wine 'Moldova' had the lowest degree of the main attack of vine diseases (powdery mildew, downy mildew, grey mold) and phylloxera attack. Regarding the accumulation of sugars in the grape, sugar content varied between 164 and 190 g/L at the wine varieties and between 154 and 171 g/L of table wine varieties, distinguishing varieties are 'Admira' and 'Radames'. Regarding the analysis of the main volatile compounds shows that limonene, hexanol, 2-methyl propanol and 3-methyl butanol is found in highest concentration in all varieties; as regarding terpenes, at the expression of olfactory characteristics of grapes, in the highest proportion is limonene, in lower concentration being found terpens as: cymene, pinene, myrcene.
