• Karyotypes of 15 accessions belonging to five species of Vicia were determined. Chromosomes number varied between species and subspecies. V. cordata had chromosome count of 2n=10 V. angustifolia had 2n=12 V. narbonensis V. monantha ssp. calcarata and ssp. cinerea presented 2n=14. Both V. sativa ssp. amphicarpa accessions with aerial and underground pods showed 2n=14 and were first reported. Chromosome numbers of V. sativa ssp. sativa were verified and revised as 2n=10 12. Therefore our karyological data provided information about phylogenetic position of the analysed species. Vicia narbonensis had the most symmetrical karyotype and could be considered as the primitive among the studied species. Vicia monantha had metacentric chromosomes with high differences in relative size between the chromosomes of the complement showing an asymmetrical karyotype. V. sativa ssp. sativa was the only subspecies having a metacentric chromosome marker in its complement within the species. Both V. cordata and V. angustifolia had all subtelocentric chromosomes showing an evolutionary tendency. Principal component analysis and Cluster analysis revealed that the studied species were grouped regarding to their evolutionary tendency. Our results support that the karyotypes analysis showed distinction between the taxa. 2014 Friends Science Publishers
