Abstract :
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.
