ResumoThe paper presents an up-to-date description of some autochthonous, old and valuable grapevine varieties maintained within the germplasm collection belonging to the University of Agronomical Science and Veterinary Medicine Bucharest, respectively 3 varieties for red wines ('Feteasca neagra', 'Babeasca neagra', ‚Busuioaca de Bohotin') and 6 varieties for white wines ('Feteasca alba', 'Feteasca regala', 'Galbena de Odobesti', 'Grasa de Cotnari', 'Tamâioasa româneasca' and 'Zghihara de Husi'). The results obtained by applying standardized methodology for grape quantitative and qualitative parameters for three consecutive years, reveal the main characteristics for each variety and also the specific genotype response to particular pedoclimatic conditions. In comparison to 'Cabernet Sauvignon' as reference cultivar, 'Babeasca neagra' and 'Busuioaca de Bohotin' varieties were characterized by higher values for the sizes and weights of the berries, and 'Feteasca neagra' by heavier bunches and higher sugar juice content. The white grape varieties in comparison to 'Chardonnay' as reference cultivar, were remarked either by bigger bunches with high to very high sugar content ('Feteasca regala', 'Grasa de Cotnari', 'Tamâioasa româneasca'), or by constancy of bunch weight and titratable acidity of must ('Feteasca alba', 'Galbena de Odobesti' and 'Zghihara de Husi').
