Narrative

Tested in four Central Great Plains and two Northern Great Plains sites during the period 1990-1997. In both the Central and Northern Plains locations, greater average forage yields than the other fairway type crested wheatgrass (A. cristatum) cvs. and had forage yields that were equivalent to those of the best standard crested wheatgrass (A. desertorum) cvs. The in vitro dry matter digestibility (IVDMD) and protein content was similar to that of the other stains and cvs. evaluated. Erect, caespitose growth habit typical of crested wheatgrasses. Culms and leaves are glabrous and non-glacuous and leaf margins are smooth. Leaves green-yellow or Munsell 5GY 4/4. Sheaths have ligules, sheath margins smooth, and auricles are present. Spikes tapering, erect, and have green, lanceolate, awned glumes. Spikes dense. At 41 deg. N Lat. in the Central Great Plains, heads the last third of May. Ninety-five percent of the plants in a population are diploids, the remainder are tetraploids. Although geneticaly heterogeneous, is similar in phenotypic uniformity to other crested wheatgrasses. Typically about 3 to 5 cm taller in height than A. cristatum cvs. such as Fairway or Parkway and 10 to 12 cm in height shorter than A. desertorum cvs. such as HyCest and Nordan. Head length shorter and head width larger than that of standard crested wheatgrass cvs. Adapted to USDA Plant Hardiness Zones 3,4, and 5.
