Interpretive Summary: NU-ARS AC2 crested wheatgrass is a broadly adapted, complex composite population developed from fairway-type germplasm accessions collected in the former USSR in 1977. It was released in September, 2002 by the USDA, Agricultural Research Service; Agricultural Research Division, Institute of Agricultural and Natural Resources, University of Nebraska; and the USDA, Natural Resources Conservation Service. NU-ARS AC2 is a Fairway type of crested wheatgrass adapted to the Central and Northern Great Plains, USA. In trials in these regions, NU-ARS AC2 had greater average forage yields than the other fairway type crested wheatgrass cultivars and its yield equaled that of the best standard crested wheatgrass cultivars even though it's about six inches shorter in height. It should provide genetic diversity and high, stable yields when used to re-seed cool-season pastures and rangeland in the mid- and short- grass ecological regions of the Central and Northern Great Plains.
