In Australia, little work has been carried out on the im-provement of tropical or subtropical pastures in recent years. There seems to be an increasing demand for pas-tures that can withstand heavy grazing, while producing high yields of high quality forage in the humid subtropi-cal regions of Australia. Most graziers, who live in these areas, have small acreages, which they graze intensively. Cynodon spp. represent a potential source of grasses with these attributes. This study will evaluate the pasture potential of a large number of bermudagrass (Cynodon spp.) ecotypes collected from across Australia.
