چکیده

Astragalus L. is a perennial herbaceous genus belonging to the family Fabaceae. Chromosome morphology was defined for the first time in four species of Astragalus namely; A. antalyensis A.Duran & Podlech, A. nezaketae A.Duran & Aytaç, A. cariensis Boiss. & A. schizopterus Boiss. All species contained diploid chromosome numbers of 2n = 16. However, polyploid cells (4x = 32) were also observed in A. schizopterus and A. antalyensis. Astragalus nezaketae species had two double satellite chromosomes. Karyotypes of species were made using an Image Analysis System. Chromosome numbers are all first reports, except for that of A. schizopterus.
