production, and high seed production. It has the
<br />largest seed of intermediate wheatgrasses, averaging
<br />66,000 seeds per pound. It is adapted for soil erosion
<br />control, roadside stabilization, mine spoil
<br />stabilization, hayland, pastureland both dry and
<br />irrigated, and forage for livestock and wildlife.
<br />Certified seed is available and Aberdeen PMC
<br />maintains breeder seed.
<br />'Slate' intermediate wheatgrass was developed from
<br />seed originating from a derivative of'Am& and
<br />another accession. It was developed by the Nebraska
<br />AES and ARS and was released in 1969. It was
<br />selected for strong rhizomatous spread, erect form,
<br />broad flat leaves, and slate green color. It is adapted
<br />for use in the central Great Plains region. Certified
<br />seed is available and breeders seed is maintained by
<br />Nebraska AES and ARS.
<br />'Tegmar' intermediate wheatgrass was developed
<br />from seed originating in Turkey. It was developed by
<br />Pullman PMC and was released by Idaho-
<br />Washington AES and Aberdeen and Pullman PMCs
<br />in 1968. It was selected for long life, late maturing,
<br />vigorous seedlings, rapidly developing rhizomes,
<br />drought tolerance and dwarf growth form. It is
<br />generally about half the height of other intermediate
<br />wheatgrasses. Intended for use in erosion control,
<br />roadside and ditch stabilization, dam stabilization and
<br />grassed waterways. Certified seed is available and
<br />Aberdeen PMC maintains breeder seed.
<br />'Topaz' pubescent wheatgrass was developed from
<br />seed originating in Turkey. It was developed by
<br />Pullman PMC and was released by the California-
<br />Idaho-Oregon-Washington AES and Aberdeen-
<br />Lockford-Pullman PMCs in 1953. It was selected for
<br />seedling vigor, vigorous growth, late maturing, sod
<br />formation, and drought resistance. It forms sod
<br />faster, is more adapted to poor fertility, higher
<br />elevations and saline conditions than most pubescent
<br />wheatgrasses. Intended use is soil erosion and site
<br />stabilization. Certified seed is available and
<br />Aberdeen PMC maintains breeder seed.
