PERENNIAL RYEGRASS IMPROVEMENT IN AUSTRALIA

Perennial ryegrass is one of the most researched and valuable temperat e pasture grasses in the world. Historically, there has been minor att ention given to its improvement in Australia, although at least six mi llion hectares of perennial ryegrass-based pastures are used for the s heep, dairy, and meat industries. The performance of introduced cultiv ars of perennial ryegrass is reviewed and the main breeding objectives in Australia are discussed. A model for the National Perennial Ryegra ss Improvement Program is briefly outlined, together with a range of s upport research considered necessary for the long-term success of the programme. Collaboration between public breeders and private seed comp anies would strengthen the programme by combining scientific expertise and support research with breeding, seed production, and commercialis ation skills and ensure a balanced focus on industry and market needs.
