A hexaploid bermudagrass plant appeared in our breeding nursery. The unexpected plant resulted from a cross of 'Midland' Cynodon dactylon (L.) Pers. and 'Clone 2‐28' C. transvaalensis Burtt‐Davy and it carried 54 chromosomes. The vigorous, upright growth habit and early spring growth of the hexaploid give it forage potential, even though it was derived from a cross expected to give turf types. Chromosome doubling of triploid turf types may be a useful forage‐breeding technique in Cynodon .
