Four new Cocksfoot (Dactylis glomerata) cultivars have been bred for areas of temperate Australia that have annual rainfall normally considered insufficient for the species. The new cultivars were bred from plants selected for persistence and production in areas with acidic, high aluminium content soils in an earlier project. Two are fine-leafed lines bred from selections from Morocco, one is a replacement for cv. Currie and was bred from persistent plants of three cultivars – Currie, Jana and Medly. The last is a selection from a Portuguese accession – AVH48. Five field experiments were established in 2009 and 2010 in Victoria and NSW to evaluate these new cocksfoot cultivars. Establishment density was satisfactory for all treatments at all sites (range 46-263 plants/m2 ). There were differences within sites and between sites. These experiments are ongoing but total herbage production to date indicates strong genotype x environment interactions. Unusually high summer rainfall in 2010/11 (up to 375% of the mean summer total at one of the Victorian sites) has not put selection pressure on the treatments to persist but the two fine leafed lines, bred from Moroccan genotypes, have been the most productive at the two southern NSW sites, Beckom and Trungley Hall. The Currie Replacement line and AVH48 have outproduced Currie at three of the four southern sites. If the new cultivars are successful in these experiments their commercial use will allow persistent perennial grass-based pastures to be established where currently the only option is unproductive annual grass pastures.
