Narrative
Washoe Germplasm basin wild rye release is a key species for reclamation of disturbed mine lands in the Intermountain West due to its tolerance to a wide range of soil pH levels as well as elevated heavy metal and arsenic concentrations. Washoe germplasm is typical of the species, having the same general morphological and physiological characteristics as others in the species. Basin wildrye is a tall, coarse, robust, perennial bunchgrass native to the Great Plains and Intermountain regions of the western United States. It is a long-lived, cool season grass with extensive fibrous roots and a few short rhizomes. This selection of Basin wildrye may produce clumps that reach 3 ft in diameter and grow 6-10 ft tall. The leaf blades are long, wide, and flat with long, pointed, clasping auricles. It has a prominent membranous ligule. The reproductive stems are dense, stout, and strongly erect. Seedheads are 6-10 inches long. Growing points are located 10-12 in above the soil surface. This selection has 388 seeds/gram. Seeds mature from late July through early August in south-central Montana. For seed production purposes, seed should be planted in the spring with a disk or furrow drill in a firm, weed-free seedbed at a depth of 0.25-0.75 inches, 24 seeds per liner foot using row spaces of 30 inches. Under irrigation, basin wild rye will produce 250 to 500 lb/acre of seed for 5-7 years.
