Narrative
Collected from a site classified by USDA-NRCS as Major Land Resource Area D25 (Owyhee High Plateau). Average annual precipitation at Tuscarora is 312 mm. Removal of the awn without resultant seed damage has been problematic in Sand Hollow big squirreltail germplasm. Mass of the proximal centimeter of the awn was 0.266 mg at Evans Farm, Millville, UT in 2001, 34% lower than Sand Hollow. The less robust awn makes the seed more amenable to debearding. Earlier than Fish Creek or Sand Hollow germplasms. Rachises disarticulate indeterminately at each node, while rachises of Fish Creek disarticulate determinately at the base of the spike. Exhibits later spring green-up than Fish Creek.
