Performance of fungus-tolerant grapevine cultivars in different production systems

Fungus-tolerant grapevine cultivars

Rezumat

Several fungus-tolerant grapevine cultivars have been created and have already found their place in vineyards in Serbia and Hungary. The aim of this work was to  investigate the differences in yield, grape quality and wine sensory properties  obtained in two different production systems of pathogentolerant white grapevine cultivars Backa and Panonia over the 2015-2018 period. The paper showed differences in harvest parameters between the Conventional and NoPes&MinFert  (without use of pesticides and mineral fertilizers) production systems. Fruitfulness  and bud tolerance to low temperatures in these production systems were also  examined. The results suggest that grape quality obtained by NoPes&MinFert was  at the same level as that achieved by conventional methods, while the yield loss 
in NoPes&MinFert was on average <20% compared to the conventional system.  Although the number of inflorescences per node and yield were higher in conventional production, NoPes&MinFert production showed satisfied yield that  exceeded 10 t/ha. Wine sensory analyses showed that production NoPes&MinFert  achieved better wine score compared to the wines derived from the Conventional production.
