چکیده	In this study, original mitotic chromosome counts have been presented for 10 populations belonging to 6 species of Astragalus sect. Onobrychoidei: A. aduncus, A. arguricus, A. cancellatus, A. lilacinus and A. vegetus. All taxa were diploid and possessed 2n = 2x = 16 chromosome number, consistent with the proposed base number of x = 8. In addition, meiotic studies revealed chromosome number of 2n = 2x = 16 for A. aduncus21 and A. brevidens and also 2n = 4x = 32 for A. vegetus99. Although this taxon displayed regular bivalent pairing and chromosome segregation at meiosis, some abnormalities were observed.
