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.
