Thinopyrum intermedium

Intermediate wheatgrass

Previous scientific name(s): Agropyron aucheri, Agropyron ciliatiflorum, Agropyron gentryi, Agropyron glaucum, Agropyron intermedium, Agropyron

Formerly known as Agropyron intermedium, or as Elytrigia intermedia ssp. intermedia. Cool season, robust, moderately drought tolerant sod-former, 2 to 4 ft. tall. Adapted to a wide variety of sites but does best on medium to fine textured soils. Generally good palatability to livestock and wildlife.

Varieties: 
Clarke
Rush

Superior seedling emergence and vigor over other choices. Achieves greater stand density and height quicker than previous releases. Equal or higher forage production than Oahe. (Released 1994, source of ecotype: Berlin, Germany)

Variety Release Notes: 
Chief

Developed for pasture and hayland production in northern latitudes of the U.S. and Canadian prairie region. Well adapted to remain productive under heavy grazing pressure for up to five years. Maintains good productivity under moderate to light grazing for longer than five years. (Released 1961, source of ecotype: former USSR)

Oahe

High seed and forage producer, and good resistance to rust. A blue-green type with vigorous sod-forming capability. (Released 1961, source of ecotype: former USSR)

Reliant

Developed for its persistence and sustained hay production in the Northern Great Plains region. Vigorous and winter hardy. Matures relatively late, weakly rhizomatous and is strongly resistant to leaf spot. Distinguished from other cultivars by its upright growth habit. (Released 1991, source of ecotype: six clone synthetic with parentage from Eurasia)

Tegmar

A dwarf strain (½ the height of other varieties) with excellent drought tolerance. Forms a dense sod, often used as a lowmaintenance turf. Resistant to Banks Grass Mite. (Released 1968, source of ecotype: Bolu, Turkey)
