PERENNIAL RYEGRASS IMPROVEMENT IN AUSTRALIA

Perennial ryegrass is one of the most researched and valuable temperate pasture grasses in the world. Historically, there has been minor attention given to its improvement in Australia, although at least six million hectares of perennial ryegrass-based pastures are used for the sheep, dairy, and meat industries. The performance of introduced cultivars of perennial ryegrass is reviewed and the main breeding objectives in Australia are discussed. A model for the National Perennial Ryegrass Improvement Program is briefly outlined, together with a range of support research considered necessary for the long-term success of the programme. Collaboration between public breeders and private seed companies would strengthen the programme by combining scientific expertise and support research with breeding, seed production, and commercialisation skills and ensure a balanced focus on industry and market needs.
