Sažetak

Nine taxa of Potentilla species from Poland representing P. sect. Terminales (Dõll.) Gren et Godr. and P. sect. Aureae (Wolf) Juz. were analyzed via a series of random amplified polymorphic DNA (RAPD) analyses to test (1) the hypothesis that the six species representing P. subsect. Collinae Juz. of the P. Terminales sect., i.e. P. collina Wibel, P. thyrsiflora Zimmeter, P. wimannania Günther et Schummel, P. leucopolitana P. J. Müll., P. ´gabarae Kolodziejek, P. koernickei Zimmeter, are genetically differentiated enough to be considered as separate taxa, and (2) the position of populations of P. thyrsiflora and P. collina with respect to the Terminales sect. (P. argentea L) and the Aureae sect. (P. tabernaemontani Ascherson and P. incana P. Gaertner, B.Meyer et Scherb.). RAPD-based genetic similarity values using the UPGMAmethod and corresponding dendrogram exhibited incomplete accordance between RAPD and morphological variations. According to 'overgenomic' associations based on a series of genomic loci selected at random, P. thyrsiflora and P. collina are closely related and similarly related to the species: P. argentea, P. tabernaemontani and P. incana hypothesized as being 'parental'. Within Terminales sect., our dendrogram shows P. argentea to be relatively isolated from the other members of the section analysed, P. thyrsiflora and P. collina.
