A native herbaceous perennial legume is showing promise as a pasture species for Western Australia's low to medium rainfall cropping zone.
This finding is the result of a joint study between researchers at The University of Western Australia and the GRDC supported Future Farm Industries Cooperative Research Centre.
According to PhD student Richard Bennett, School of Plant Biology, UWA, native perennial legumes from the genus Cullen could outperform lucerne on infertile acid soils in the low-medium rainfall zone.
Mr Bennett said C. australasicum X and C.cinereum, which showed remarkable productivity on the Fortescue River Floodplain in northern WA, are being trialled on sandy acid soils at Buntine in the WA wheatbelt.
"C. australasicum is very promising and selection and breeding trials have already commenced," Mr Bennett said.
However, it will be some years before a Cullen species is commercially available.
