Popis:	Four varieties of perennial ryegrass are compared throughout the seeding year and the first four harvest years (1954–58). Two of the varieties, Irish ‘commercial’ and New Zealand, are of ‘early’ type; and the others, Glasnevin and S23 are, ‘late’. New Zealand gave the most grazing, 1% more than ‘commercial’ and Glasnevin, and 5% more than S23. The ‘early’ varieties contrasted markedly with the ‘lates’ in seasonal growth. In persistency and in resistance to invasion by unsown species, the ‘lates’ were better than the ‘earlies’ S23 was outstanding, and New Zealand had an advantage over ‘commercial’. The ‘earlies’ were the more compatible with clover. New Zealand appears to have most merit, but sowing of more than one variety may give better results.
