Thirteen new grapevine varieties for white wines’ behaviour was studied between 2015-2019, under climate change conditions in the ampelografic collection of the UASVM Bucharest. During the experimentation period, as compared to the reference period (1981-2010), the average temperature during the growing season increased by 0.75ºC, the average annual maximum temperatures by 1.26ºC, number of hot days by 21, number of very hot days by 6.2 and Huglin index by 140 units. Phenological cycles (budburst to harvest) varied between 138.6 and 140.6 days, with Aromat de Iași and Crâmpoşie selecţionată - the most precocious varieties and Columna - the latest variety, as an average of 5 years of experimentation. Due to the high temperatures during the growing season, phenological stages were anticipated, the harvesting being anticipated by approximately 15-25 days. The highest value of sugar content of must was for Aromat de Iaşi variety (23.33ºBrix) and the lowest value for Astra (19.38ºBrix). Aromat de Iaşi, Crâmpoşie selecţionată and Şarba varieties have been distinguished by the best qualities.
