Importance of new grapevine cultivars in mitigation of negative effects of climate change

Abstract

The aim of this work was to investigate the differences in yield and grape quality among three grapevine cultivars Dionis, Morava and Panonia during the period 2015-2022. The results suggest that season highly affects grape quality of all tested cultivars. Among the all tested cultivars, Morava had the lowest variation in bunch weight, while the lowest variation in acidity was demonstrated by Panonia. On average, these cultivars had satisfying yield (0,91-1,41 kg/m2) and even the production was performed according to ecological principles, without the use of pesticides. Colored cultivar Dionis and its parent Panonia, showed high sugar content in the grape must. Panonia and Morava had significantly higher acidity of the must (8.4 and 7.8 g l-1), compared to Dionis (6.30 g l-1).
