The issue of returning to the ancestral varieties from the old sortiment specific to Romanian vineyards in the context of global warming and the conservation of biodiversity in wine-growing areas, represents one of the main directions of scientific research. The old Romanian grape varieties are currently preserved in ex situ germplasm collections (ampelographic collections) at the research units in the viticulture field. This paper presents preliminary results regarding the agrobiological and technological characteristics of four old autochthonous grape varieties (Vitis vinifera L.) for white wines ('Galbenă de Odobești’, 'Cruciuliță’, 'Pîrciu’ and 'Gordin’), in the climatic conditions of the year 2024 in Odobești vineyard, Vrancea county. In the drought conditions of year 2024, these varieties demonstrated a high fertility potential (63.2-89.6% fertile shoots) and valuable technological characteristics, with a production that varied between 2.26 kg/vine for 'Pârciuʼ variety and 4.43 kg/vine in 'Cruciulitaʼ variety, under the conditions of a good accumulation of sugars in the berries (>190 g/L) and a balanced total acidity (>5.1 g/L as tartaric acid).
