Description
Persistence of 12 genera of perennial grasses was examined on 2 soil types at Green Range (annual rainfall 600 mm), in southern Western Australia, Tall wheat grass was found to be a good all round performer iit terms of persistence and production with 78-79% survival and an average dry matter (DM) production of 61 kg/ha/day. Four cultivars of Festuca ar11ndinacea were in the top 6 performers at the wetter site, producing .58-66 kg/ha/day during the sampling period even though their plant survival was less than 62%. VSPG006 (now released as Roper) and Kangaroo Valley perennial ryegrasses had significantly • better (P<0.05) plant densities than other lines after 3 years at the "dry" site. Similarly at the "wet" site, the plant densities of VSPG 006, VSP 12, Kangaroo Valley, Marathon and Bllett perennial ryegrasses were significantly better than the remainder of the lines. Good plant density did not necessarily indicate DM production. This: work shows perennial grasses have the potential to persist and be productive in specific niches within southern Western Australia,
