Narrative
Cool season perennial bunchgrass. Selected for agronomic performance, earlier phenological development (spring recovery and maturity) and uniformity. Good vigor, seed yield (mean 514 lbs/ac, range 380-623), and stand longevity compared to Arlington and other populations. Matures seed 7-14 days earlier and initiates growth 15-30 days sooner in spring than Arlington. Foliage grass green and lacks glaucous appearance. Mean culm height 118 cm (range 95-140). Seed weight 140,000 seeds/lb, average of 3 lots. Stems intermediate in coarseness, often bent at base. Lower, younger sheaths are purple tinged at base, pubescent. Leaf blades nearly glabrous, flat, lax, and width 6-14 mm. Spikes erect, length 8-20 cm. Lemmas glabous to scabrid-pubescent.
