Multidimensional scaling plot of single nucleotide polymorphisms from 47 desirable and off-type bermudagrasses sampled from golf course putting greens, five ultradwarf bermudagrass (Cynodon dactylon (L.) x C. transvaalensis Burtt-Davy) cultivars, and two progenitor species (Cynodon dactylon (L.) Pers. and C. transvaalensis Burtt-Davy).

The multidimensional scaling plot plot revealed clear clustering of the progenitor species (DA1&2, DB1&2, TA1&2, and TB1&2) from ultradwarf bermudagrasses and the majority of off-type grasses. The plot also revealed clear clustering of ‘Tifway’ hybrid bermudagrass (TW 1 – 6) from ultradwarf bermudagrasses, off-type grasses, and progenitor species. Of the 47 samples selected from golf course putting greens, only 5 (~11%) were genetically divergent from ultradwarf bermudagrasses.
