Vine varieties react differently to the influence of environmental factors by decreasing or significantly intensifying the vigour of shoot growth, a biological reaction that also affects fertility and productivity. This article presents data on some agrobiological properties (vegetative growth of shoots, fertility and productivity) of some white wine varieties, created at the Research and Development Station for Viticulture and Vinification (R.D.S.V.V.) Odobeşti, Vrancea County, Romania) - Şarba, Băbească gri, Miorița and Vrancea, in the period 2020 - 2021. The data obtained were compared with the control variety Fetească regală. In Odobeşti vineyard, 2020 was much warmer than normal, characterized by a severely deficient rainfall regime resulting in atmospheric drought, followed by the gradual development of pedological drought. The vigour of shoots was negatively influenced by the climatic conditions of the vegetation period in 2020, the highest values being recorded for the varieties Şarba (159.6 cm) and Vrancea (141.5 cm), which showed significant positive differences, compared to the control variety. The fertility of the buds was lower in 2020, compared to 2021, the Vrancea variety being distinguished by higher potential fertility than the varieties Şarba, Băbească gri and Miorița, but lower potential fertility than the control variety. The absolute fertility coefficient (Cfa) had superunitary values for all varieties (1.07 - 1.50), and the relative fertility coefficient (Cfr) had subunitary values, except for the Vrancea variety (1.32). The varieties Şarba, Băbească gri and Miorița achieved an absolute productivity index (Ipa) superior to the control variety Fetească regală due to the higher average weight of the grapes, and the relative productivity index (Ipr) ranged from 199 for the Vrancea variety to 182 for the variety Şarba.
