This study was conducted to determine the number and morphological features of somatic chromosomes of yellow bluestem (Bothriochloa ischaemum (L) Keng) dominated in natural maqui type range vegetation of Çukurova region. The results showed that 39 out of the 40 ekotypes had 2n=60 and only one had 2n=50 chromosomes. It was determined that all the chromosomes of yellow bluestem were metacentrich and their lengths ranged from 1.3006 mm to 3.1294 mm. The cytotype with 2n=50 had two pairs of chromosomes with satellite and the cytotype with 2n=60 had three pairs of chromosomes with satellite.
