10 th <strong>Symposium</strong> on the Flora of Southeastern Serbia and Neighbouring regions,Vlasina 17 to 20 June 2010Variabillity of the Larg Yellow Vetch Vicia grandiflora Scop.1772 (Fabaceae, Vicieae)Anačkov, G., Boža, P.University of Novi Sad, Faculty of Sciences, Department of Biology andEcology, Serbiagoran.anackov@dbe.uns.ac.rsThe large yellow vetch (Vicia grandiflora Scop. Fl. Carn. 2:65 (1772)) is aPontic-Balkan-Caucasian species native to the Southeastern Balkans. It is commonon the territory of Serbia, especially in the Pannonic floral region. It grows invarious habitats, most typically on grassy patches, pasture lands, and meadows. Itstaxonomic variation on the territory of the Pannon Plain includes three variants andtwo forms. The variants differ in leaflet shape, whereas the forms are distinguishedon the basis of flower hue.Using comparative morphological methods, we have carried out a taxonomicand variation analysis of the large yellow vetch on individuals collected in threepopulations on the territory of Novi Sad. The analysis concentrated on more than 30morphological features in 30 individuals from each population. The features havebeen grouped into quantitative and qualitative categories. We have subdivided thecategory of quantitative features into measurement and calculation subcategories.Both the quantitative and qualitative features have been statistically analysed withthe Statistica for Windows ver. 80 software package, relying on the method ofmultivariational analysis.The preliminary findings have proved to be promising and may be furtherverified by more detailed analyses still ahead. We have found completely newfeatures that are not mentioned in the literature at all. Based on these results, it maybe possible to describe a new variant of the large yellow vetch. This new variantdiffers from those already described in leaflet shape, vexillum colour and size, aswell as seed colour.17
