Evans is a tetraploid perennial ryegrass with a late heading date, high tiller density.
Evans was bred in New Zealand by the late DLF plant breeder Pedro Evans. In 2007 Pedro began a programme to breed and improved tetraploid perennial ryegrass, focusing on increased growth in winter and spring, and high grazing tolerance and good persistence. One of those crosses performed exceptionally in trials around the country. The table below showed the yield of Evans without endophyte versus cultivars with endophyte.
Evans is available with low levels of endophyte infection (LE), and is therefore not suied to regions with high insect pressure.
Evans has a high tiller density for a tetraploid cultivar, and this is important as the improved palatability of Evans could make it prone to overgrazing if it only had a traditional density.
Evans can be used in any part of New Zealand where farmers want the best possible combination of feed production at crucial times of the year, and animal performance.
Evans has excellent annual production, equal to the best ryegrasses available (see table below). A key strength of Evans is growth in winter and early spring, when it is more productive than most other cultivars.
