Narrative
The United States Department of Agriculture - Agricultural Research Service announces the public release of the cultivar `Stabilizer? Siberian wheatgrass [Agropyron fragile (Roth) Candargy] as a low growing, rapid establishing revegetation grass for use on rangelands and roadsides, and as a grass component in fire strip plantings in the Intermountain West, Great Basin, and Northern Great Plains Regions of western U.S. Selection emphasis in Stabilizer was for seedling establishment, persistence, seed production, pubescence, and reduced forage yield. During the establishment year, Stabilizer had similar numbers of seedlings per unit area (m2), using a frequency grid, as did the cultivar `Vavilov II? at Guernsey, WY, Dugway, UT, Beaver, UT, Fillmore, UT, and Malta, ID; and the cultivar `Vavilov? at King Hill, ID and Spring City, UT. Stabilizer persisted similar to Vavilov II at Guernsey, WY, Fillmore, UT, and Beaver, UT, but was significantly more persistent than Vavilov II at Malta, ID. Stabilizer had significantly less dry matter yields (0.25 kg plot-1) at Beaver, UT compared to Vavilov II (0.53 kg plot-1), and Vavilov at (0.60 kg plot-1). Stabilizer was genetically distinct and unique with respect to the other available Siberian wheatgrass varieties.

Pedigree
Description:
Stabilizer originated from six collections of pubescent, narrow-spiked Siberian wheatgrass from Kazakhstan [PI 598669, PI 598670, PI 598671, PI 598674, PI 598675, and PI 598714]. The parent material was selected based on dry matter yield, seed yield and mass, and seedling emergence from a 7.6-cm planting depth, pilose leaves, leaf sheaths, and spikes, 39 genotypes were selected representing PI 598669 (11 genotypes), PI 598670 (2), PI 598671 (11), PI 598674 (5), PI 598675 (8), and 598714 (2).
