N2  - Nine lines of Dactylis glomerata, five of Phalaris tuberosa, two of Festuca arundinacea, and two of Lolium perenne were compared over a three year period for survival and seasonal yield on two sites on lateritic gravelly soils in south-western Australia. On plots sown broadcast at two seeding rates and grazed periodically, yield and density were measured. On other plots that were drill sown and grazed either continuously or rotationally, density only was measured. In the broadcast plots, there was no interaction between seeding rates and plant yield or plant density. There were significant differences in yield of sown grass between lines in all years, but in total yield (i.e. sown grass plus volunteer annuals) at one site only. Significant differences in density between lines were recorded in all plots. At one site final plant density was similar in the broadcast and drill sown plots, whereas at the second site there were large differences between the broadcast and drilled plots. On a survival and yield basis the best lines of each were D. glomerate cv. Currie, P. tuberosa cv. Australian, F. arundinacea CPI 15301, and L. perenne CPI 15914. F. arundinacea gave outstanding winter yields.
