Thirtyfive autochthonous populations of the species Agrostis stolonifera L. collected from a narrow Serbia region (Yugoslavia), were subjected to both univariate and multivariate analysis. The plants were collected from various habitats: valley meadows - 22 populations, hilly meadows - 7 populations, mountain meadows and pastures - 6 populations. The populations of the species Agrostis stolonifera L. exhibited three levels of polyploidness: diploid, tetraploid and hexaploid. The effect of the eleven most important quantitative characters was examined. In order to establish a taxonomic connection among germplasm accessions, similar populations were grouped in three clusters. All clusters represented homogeneous groups. It was not possible to differentiate between the 35 populations on the basis of their ploidy level and their habitats.
