Domesticating Australian native legumes for pastures: a case study in Cullen
Perennial pastures have been advocated as an effective way to combat environmental degradation caused by dryland salinity and improve productivity in southern Australias wheatbelt.However, there are currently few perennial legume cultivars that can be widely used in Western Australia ( WA ), with lucerne ( Medicago sativ a ) not adapted to drought conditions, acid soils and waterlogging, conditions common in WAs wheatbelt.Cullen spp.have been shown to have some potential for pastures in Queensland (Britten and De Lacy 1979) and in South Australia (Dear et al.2007) but to date, use in WA had not been evaluated.Our approach included ecogeography to select native Cullen species potentially adapted to WAs wheatbelt, field trials of selected species to test adaptation, productivity and persistence, and a common garden experiment (CGE) to identify useful variation in agronomic characters in lines from germplasm collections of wild populations.
