The research carried out in the period 2020-2022 looked at the biological, productive and quality potential of four grape cultivars for red wines (Băbească neagră, Haiduc, Novac, Arcaș), studied in the ampelographic collection of the Research-Development Station for Plant Culture on Sands Dăbuleni. The obtained results showed that the beginning of bud burst phenophase of these cultivars with grapes for red wines started at temperatures between 11.5-18.20C, the earliest being the Novac cultivar, which beginning of bud burst between April 16 and May 10. The vegetation period for red wine grape cultivars was between 159-164 days, under the conditions of recording an active heat balance between 3429.4-34910C. From the point of view of productivity, the Novac cultivar stood out with a grape production of 20479 kg/ha, registering a difference of 6579 kg/ha compared to the control, statistically assured as distinctly significant. The quality recorded at harvest maturity of the grapes revealed values of the content in total sugars between 180 g/l for the Arcaș cultivar and 200 g/l for the Novac cultivar.
