This study concerns the relationships among 40 taxa belonging to 13 sections of the genus Vicia occurring in Iran using chromosomal (mitotic) studies. Based on the results of this study, there are 37 diploid (2n=10, 12 and 14) and 3 tetraploid (2n=28) taxa for the flora of Iran. Based on these observations three basic chromosome numbers (x=5, 6 and 7) were determined in the Iranian gene pool of Vicia. There are some ploidy reports for V. cracca and V. villosa subsp. dasycarpa in the world but in this study just has been seen diploid cytotypes in Iran. Most of karyotypes in the genus showed submetacentric (sm.) (54.38%), subtelocentric (st.) (26.31%), metacentric (14.38%) and telocentric (3.15%) chromosomes which mostly longest and shortest ones are submetacentric and subtelocentric, respectively. Stebbins’ karyotype classes were of 2A, 3A, 4A, 3B and 4B which in this system are considered as relatively primitive and therefore symmetrical karyotypes. Highest value of TF% (37.57) and lowest value of A1 (0.39) belonged to V. narbonensis as symmetrical karyotype and highest value of A1 (0.82) and highest value of TF% (13.15) belonged to V. michauxii as asymmetrical karyotype in Iran.
