Karyology Study of Six Cytotypes of Vicia L. in Tehran Province, Iran

The genus Vicia L. is an important forage crop and consists of approximately 160 annual perennial species. This has variety in phenotypic characters. In this study, six genotypes taxon was choosen to determine the chromosome numbers, ploidy levels compare karyotypic trairts. Based on results, basic number varied from x=5, x=6 x=7. According Stebbins classification, species were classified as symmetric class 3A. intra chromosomal symmetry, V. villosa Roth. had most asymmetrical evolutionary karyotype. cordata (Wulf. ex Hoppe) Arcangeli, Comp. symmetrical highest distance observed between these two using cluster analysis.
