The objective of this study was to evaluate diversity and relationships among
grapevine cultivars from the Serbian gene bank in Sremski Karlovci, and to
identify the most useful variables for discrimination. A total of 54
grapevine cultivars have been studied. During the period 2000-2005, twelve
quantitative and qualitative characteristics were evaluated using OIV
categories to each trait. Characterization was done using multivariate
statistical analyses: cluster and principal component analysis (PCA), Based
on cluster analysis cultivars divided into three major groups and the
clustering pattern was related to the classical eco-geographical grouping:
occidentalis, pontica and orientalis. Beside geographic origin clustering
position of cultivars throughout the dendrogram was related to main uses. The
major part (70.1%) of the total variation presented was explained by four
principal components. PC1 is highly correlated with the bunch and berry size
and PC2 with the density of prostrate hairs of young shoot tip and the
density of prostrate hairs between veins on the lower side of mature leaf.
The overall arrangement of cultivars suggests considerable phenotypical (and
presumably genetic) variability in studied germplasm collection. Furthermore,
obtained results may be useful for further utilization of available genetic
resources in gene bank managers, growing and breeding.
