Narrative

Tested in four Central Great Plains and two Northern Great Plains sites during the period 1990-1997. Had the greatest average forage yields at both the central and northern Great Plains sites when evaluated with released cvs. and other experimental strains of intermediate wheatgrass. Forage quality as measured by IVDMD and protein concentration is less than that of Beefmaker but is similar to that of other released cvs. of intermediate wheatgrass. Recommended for dryland hay production in the Central and Northern Great Plains, U.S. Erect growth habit and rhizomes typical of intermediate wheatgrass. Culms and leaves glabrous and non-glacuous and leaf margins are smooth. Leaves green-yellow or Munsell 5GY 5/4 (3). Sheaths have ligules, auricles are usually absent, and sheath margins are smooth. Spikes oblong, erect, and have green, lanceolate glumes. Spike density lax. Anthers yellow. At 41 deg. N Lat. in the Central Great Plains, at anthesis the last week of June. Head height varies with environment but it is typically taller than other intermediate wheatgrasses and has a wider flag leaf. Adapted to USDA Plant Hardiness Zones 3,4, and 5.
