Narrative
Klamath Mountains Germplasm Roemer's fescue is a native cool season, perennial bunchgrass with variable longevity and mostly basal foliage. The foliage is fine textured and densely tufted (cespitose). Morphological diversity among the five parent populations appears moderately high. Leaves are sometimes glaucous (covered with a whitish waxy coating) and their color varies throughout a wide spectrum of green and pale blue for this germplasm. Plants rarely flower until the second full growing season. Stem color ranges from yellowish green to purple or red, turning mostly straw colored at seed maturity. Mean culm (plant) heights varied from 73 to 82 cm (29-32 in) and mean basal width ranged from 10 to 14 cm (3.9-5.5 in). The panicle (seed head or inflorescence) is loosely open to moderately contracted and 5-20 cm (2-8 in) long; branches are erect to slightly spreading. The spikelets are 9-13.5 mm (0.35-0.53 in) long with 4-6 florets. Glumes are exceeded by the upper florets. Lemma awns are 2-5 mm (0.08-0.20 in) long. Leaf sheaths are closed for less than one half their length and collars are glabrous; ligules are 0.1-0.5 mm (0.004-0.02 in) long; blades are 0.5-1.2 mm (0.02-0.05 in) in diameter

Pedigree
Description:
Klamath Mountains Germplasm is the result of geographic selection and open crossing of five populations for one generation for the limited purpose of enhancing genetic diversity over single wild populations. While two lesser performing populations were excluded, this germplasm is not anticipated to have substantial genetic improvement or hybrid vigor in terms of ease of establishment, reproductive capability, and plant growth over other naturally occurring, fit populations of Roemer's fescue found within the same ecoregion.
