Abstract

Oregon is the world's major producer of cool-season forage and turf grass seed and a widely recognized center of expertise in seed production. Not surprisingly, nearly all of the annual ryegrass (Lolium multiflorum Lam.) and perennial ryegrass (L. perenne L.) seed in the USA is grown in Oregon. Mild, moist winters, and dry summers favor seed development and harvest, making Oregon's Willamette Valley an ideal place to produce high quality seed. Collectively, this small region produces almost two-thirds of the total USA seed production of cool-season grasses. Most seed produced is of turf-type cultivars. More than 55% of Oregon's production of perennial ryegrass was certified in 1995.
