Abstract: Using ‘Dornfelder’(Vitis vinifera L.)which was introduced from Penglai as the material in this study,‘Garanior’as the control variety.The differences of‘Dornfelder’and‘Garanior’in botanical character,productivity,Plasmopara viticola resistance and wine quality were investigated to survey the adaptability of‘Dornfelder’and to increase the diversity of wine grape in Yangling.The results showed that‘Dornfelder’′s mature leaf size(13.7cm×19.4cm),bunch weight(305.51g)and berry weight(2.65g)were larger than ‘Garanior’′s,and the resistance of downy mildew was also higher than‘Garanior’.The wine of‘Dornfelder’and‘Garanior’had no obvious differences in total score according to the results of sensory analysis,but ‘Dornfelder’in wine aromas was a little better than‘Garanior’.The main aromas found in the‘Dornfelder’wine were red fruits(strawberry,raspberry and cherry),black fruits(plum and mulberry),jam and wild jujube aromas.The conclusion in this paper was that‘Dornfelder’had a good adaptability in Yangling,which could be used to make good new wines.
