Interpretive Summary: The USDA-Agricultural Research Service (ARS) announces the release of Charleston Peak Germplasm slender wheatgrass as a pre-variety germplasm selected directly from collection D-3269 that originated from near Charleston Peak, Clark Co., NV at 2,438 m above sea leavel. This collection is unique in that it exhibits short rhizomes not typically found in standard slender wheatgrass and appears to have the ability to accumulate cadmium (Cd) in aboveground tissue from the soil. In addition, Charleston Peak is currently the only slender wheatgrass plant material that originates in the Great Basin. This germplasm is intended for use on arid and semiarid rangelands for revegetation in the Great Basin and Intermountain Region of western U.S.A. where it is adapted to dry to moderately moist roadsides, ditchbanks, streambanks, meadows, and woodlands from valley bottoms to subalpine and alpine elevations ranging from sea level to 3300 m (10,725 ft).

Technical Abstract: The USDA-Agricultural Research Service (ARS) announces the release of Charleston Peak Germplasm slender wheatgrass [Elymus trachycaulus (Link) Gould ex Shinners] as a selected class, genetically manipulated track pre-variety germplasm selected directly from collection D-3269. This collection is unique in that it exhibits short rhizomes not typically found in standard slender wheatgrass and appears to have the ability to accumulate cadmium (Cd) in aboveground tissue from the soil. In addition, Charleston Peak is currently the only slender wheatgrass plant material that originates in the Great Basin. Charleston Peak germplasm was collected near Charleston Peak, Clark Co., NV at 2,438 m above sea level on 30 July 1983 designated as D-3269 within the USDA-ARS Collection of the Triticeae grasses at Logan, UT. This germplasm is intended for use on arid and semiarid rangelands for revegetation in the Great Basin and Intermountain Region of western U.S.A.
