Title: Pachytene chromosome morphology of diploid Cynodon dactylon (L.) Pers.
Abstract: Diploid clones of C. dactylon were studied to determine their pachytene chromosome morphology. The chromosomes ranged in length from 20.5μm to 44.6μm. Arm ratios ranged from under 1.50 to 2.14. The chromosomes were identified by their arm length ratios, relative length and position and number of prominent chromomeres. The shortest chromosome was designated chromosome 1 and other chromosomes numbered on basis of average chromosome length. There was little variability in chromosome morphology among clones.
