Wine quality depends mainly on the characteristics of the grape it is made of, and one of the attributes affecting wine composition is cluster and berry morphology. The aim of this study was to represent variability of the morphological characteristics between different clones of the autochthonous grape variety Prokupac and to perform chemical evaluation of wines obtained from them. Total phenolic content was generally low and it ranged from 33.0 to 114.5 mg GAE/100 mL. Six main anthocyanin compounds including malvidin as the main anthocyanidin were detected. Malvidin 3-O-glucoside was the most abundant anthocyanin with concentration of 59.8 to 101.7 mu g/mL. Clones 43/5 and 43/4 yielded highest quality wines. According to the results, clonal selection makes a significant difference in Prokupac wine quality. On the other hand, there is a minor dependance of wine quality parameters to variation in morphological attributes of clusters and berries (bunch weight, proportion of stem, berry ...and seed weight, skin, pulp and seed weight per berry).
