Native grasses are present on most farms either as remnant populations or as a major component of the pasture. Landholders in the past have seldom been aware of their presence or contribution to overall pasture productivity. However today they are viewed as a valuable component of pastures, even to the extent that a number of species are undergoing domestication. Domestication of native grasses is a relatively new concept in Australia. For many years Australian native grasses were considered inferior for grazing, being regarded as having low yields and low nutritive value. However the enormous benefit of persistence through periodic dry times is now considered one of their greatest assets. As well, they can often yield equally to introduced species. Although a number of domestication programs are underway in Australia there are as yet no cultivars available for use. The current programs in New South Wales for the selection and domestication of native grasses, with the exception of Astrebla (Mitchell grass), initially involved the collection of material and assessment of within species genetic variation. This variation has been used to select types that have a higher seed retention and harvestable seed yield than most naturally occurring ecotypes. Selective breeding or crossing has not yet been used. The most advanced program is the Danthonia (Wallaby grass or White-top) program.
