| Chromosome counts of five species of the genus Astragalus including A.campylanthus and A. susianus from sect. Campylanthus; A. callistachys, A. fragiferus, and A. microphysa from sect. Microphysa, are reported for the first time. Three of the studied species including A.campylanthus (2n=2x=16), A. susianus (2n=2x=16), and A. microphysa (2n=2x=16) were diploid and 2 species including A. callistachys (2n=4x=32) and A. fragiferus (2n=4x=32) were tetraploid. A basic chromosome number of x=8 was confirmed for investigated species. Karyotypic analyses of all species are presented. | ||

| عدد کروموزومی پنج گونه از جنس گون شامل گونههای A. campylanthus و A. susianus از بخش Campylanthus و A. callistachys، A. fragiferus و A. microphysa از بخش Microphysa برای اولین بار گزارش میشوند. سه گونه شامل گونههای A. campylanthus (2n=2x=16)،A. susianus (2n=2x=16) و A. microphysa (2n=2x=16) دیپلوئید و دو گونه شامل گونههای A. callistachys (2n=4x=32) و A. fragiferus (2n=4x=32) تتراپلوئید بودند. عدد پایه کروموزومی x=8 برای تمام گونههای مطالعه شده مورد تأئید قرار گرفت. تحلیل کاریوتایپی تمام گونهها ارائه میشوند. | ||
