Seed available for distribution is a limited resource. The quantity of seed distributed is hopefully sufficient to conduct the intended research. If additional seed is required, the recipient is urged to grow and reproduce the seed. Repeated requests for seed of the same accession will not be honored.

Narrative
Developed and released as a selected class (natural track) germplasm as part of an inter-agency project to identify resilient plant characteristics and develop wear-resistant plant cultivars for use on military training lands. Sandberg bluegrass reproduces via facultative apomixis, theoretically resulting in fixed adaptation to specific environments. This multi-origin germplasm assembled from 28 locations, each potentially containing unique co-adapted gene complexes, to ensure establishment over a broad geographic area and provide a source of readily available seed. It has been successfully established in several trials in Utah and Idaho and at the Dept. of Defense Yakima Training Center in Yakima, WA. It also displayed apomictic uniformity within collections, but contained a wide diversity of genotypes among collections as evidenced by a range of phenotypes in the seed increase fields. Sandberg bluegrass is an important understory grass in the bluebunch wheatgrass-sagebrush ecological sites of the Intermountain and Northwest regions of the United States. It is a medium-lived, perennial bunchgrass valuable for soil erosion control, spring livestock and wildlife grazing, and biodiversity. It resists trampling and is often one of the first species to reestablish on sites disturbed by fire, large equipment and vehicles, and animals. The intended use for this release is for rehabilitation and restoration of western rangelands. It may be particularly useful as a pioneer plant on severely disturbed sites, such as military training sites and after wildfires.

Pedigree
Description:
314 Sandberg bluegrass plants were collected from 28 locations representing 7 different ecological zones at the U.S. Army Yakima Training Center (YTC) in Yakima, Washington. The 314 plants (G0 generation) were potted, maintained in the greenhouse, and transplanted in the spring near Logan, Utah. Seed from the original 314 plants was harvested and composited, in equal amounts per collection location, to form the G1 generation.
