Abstract: Forty perennial and 12 annual grass varieties were evaluated for seed production potential at Corvallis, Oregon. Perennial ryegrass, orchardgrass, Kentucky bluegrass, red fescue, Chewings fescue, tall fescue, and annual ryegrass were included in the study. Results of 1986 and 1987 harvest years are reported. INTRODUCTION Private and public plant breeding programs release many new varieties for commercial production each year. In many cases, seed producers are requested to produce seed of a new variety with very limited information about the comparative seed yield. Since 1981, a seed yield evaluation program has been conducted at Oregon State University. Seed yield and other characteristics of these varieties growing under western Oregon conditions were observed for two years and previously reported (Youngberg et al., 1985; 1986). A fee is charged for the service. In this study, 52 entries and standards for each species were planted for evaluation. Species included: perennial ryegrass (Lo lium perenne), Italian ryegrass (Lolium multiflorum), fine -leaf (Chewings and red) fescue (Festuca rubra), Kentucky bluegrass (Poa pratensis), orchardgrass (Dactylis glomerata), and tall fescue (Festuca arundinacea).
