Endurance is a true dual purpose orchard- grass, it excels at both grazing and harvested forage production. Persistence The germplasm used to develop Endurance was first selected for low cutting height. Plants were maintained at a 1.25 inch mowing height for three years. Survivors were then placed in a nursery and allowed to inter-pollinate. Seed was then sent to Dr. Joe Bouton of the University of Georgia. After three years of intense grazing pressure, survivors were selected and sent to Oregon. This became the base population for Endurance. The improved grazing tolerance has been demonstrated at university grazing trials in Georgia, Kentucky and Pennsylvania. In addition to persistence under grazing, Endurance endures wide temperature extremes, from the winter cold of Canada, to the heat of the south. Endurance is registered in Canada. Disease resistance is above average.
