High Sugar Leys
Grass breeding emphasis in the 1980’s changed at IGER to concentrate on producing grass varieties that offered better nutritional quality as well as keeping pace with improvements in dry matter yield, disease resistance and persistency. Some of the resultant varieties, the new high sugar grasses, offer significantly high levels of water soluble carbohydrate content (WSC) with all of the advantages described on page ??? First of these varieties were the intermediate diploid perennials AberGold and AberDart, the latter now recognised as the outstanding variety of it’s generation. Independent trials at DARD, Northern Ireland confirmed the high mean WSC content of AberDart that bettered ten other varieties, of both ploids. Calibra, an intermediate tetraploid of known high WSC content and quality, was one of only two varieties that came close to AberDart’s impressive WSC figures.AberStar, an outstanding variety, is the new high sugar intermediate diploid improving on AberDart’s impressive figures with further significant improvement in WSC content and yield as well as having the highest Grazing D value of any perennial ryegrass.
AberAvon and AberZest are the late perennial’s in the IGER high sugar portfolio, the former giving an excellent grazing performance being the highest yielding late diploid. The impact of IGER high sugar Aber tetraploid hybrid ryegrasses are a further success story of improved breeding with AberStorm and AberEcho, the highest yielding tetraploid hybrid ryegrass variety.
The Triumph Range features three leys consisting of the best genuine High Sugar grasses.
