This paper presents two new genotypes obtained at INCDBH Ştefăneşti-Argeş through controlled hybridization of Muscat de Pölöskei x Victoria (coded RVC 24) and Coarnă neagră x Victoria (VMD 24) varieties. Both the hybrid elites studied and the control Victoria were characterized and evaluated according to standardized international methodology. Phenotypic, agro-biological, and technological determinations were carried out throughout the years 2020-2023, following the 'OIV Descriptor list for grapevine varieties and Vitis species'. The RVC 24 genotype stood out for its superior agro-biological and technological potential compared to the control: high fertility at 67%, absolute and relative fertility coefficients (1.2 and 0.76, respectively), average grape weight of 476.24 g, absolute and relative productivity indices: 555 and 364 respectively, sugar content of 157 g/l. The VMD 24 genotype was notable for its high to very high fertility at 78%, average grape weight of 443.30 g, absolute and relative productivity indices: of 474 and 373 respectively, and sugar content of 155 g/l. The results obtained were correlated with the climatic data recorded during the study period, which showed significant fluctuations from one year to another.
