In the paper are presented the results of studying the agrobiological characteristics of some seedless cultivars from the Ampelographic collection of PI NIARAMV: 'Bessemeannyi V-6', 'Călina', 'Centennial seedless', 'Flame seedless', 'Kișmiș lucistâi', 'Mecita', 'Otilia', 'Perlette', 'Perlon' – V. vinifera L. cultivars and interspecific cultivars 'Himrod', 'Interlaken' and 'Romulus'. The phenological stages, fertility coefficients, productivity indices and winter hardiness were assessed, and the relationships among the main fertility components were examined through linear regression analysis. The investigated cultivars exhibited a wide range of berry maturity periods—from very early to late—together with variable levels of fertility and productivity indices. Several genotypes showed favorable agronomic traits, highlighting their potential value as genetic resources for seedless grape breeding programs.
