SUMMARY
AbstractThis paper presents results of a study on morphological variability of Fragaria vesca, F. moschata and F. viridis populations collected in their natural habitats in Serbia, Macedonia and Montenegro. The goals of the study were to determine the degree of morphological variability as well as the morphological characters with the greatest impact on differentiation of these species. The morphometric study was carried out on 7 populations (142 individuals x 19 morphological characters). Analyses included standard univariate (Descriptive, ANOVA) and multivariate (Principal Component Analysis, Canonical Discriminant Analysis, UPGMA classification) analyses. The obtained results indicate moderate to high variability in most of the analyzed characters. F. moschata has shown the highest level of variability for almost all characters in comparison to F. vesca and F. viridis. The greatest differentiation in Fragaria species was present in following characters: Leaf_L, Lam_cent_L, Lam_cent_W, Lam_lat_L, Ped_L and Sep_int_L.
