Release: P-7 - bluebunch wheatgrass

This release is available in the marketplace

SymbolPSSP6
Release NameP-7
Release Typeselected
DescriptionIntended to provide genetic diversity within a single germplasm for semi-arid to mesic sites where bluebunch wheatgrass was an original component of the vegetation. Twenty-four of the constituent populations are diploid (2n=14) and one is tetraploid (2n=28). Increased diversity is attractive to land managers because it 1) enhances the probability that some of the constituent material will be adapted to the seedling site and 2) augments the amount of genetic variation upon which natural selection can operate. Source locations: Slocan, BC; New Meadows, Pollock, and Riggins, ID; Darby, MT; Lone Mountain, NV; Durkee, Seneca, and Grande Ronde R., OR; Salina Canyon and North Logan, UT; Almota Road (Whitman Co.), Anatone, Lind, Colfax, Colton, Connell, Dayton, and Wawawai Rd (Whitman Co.), WA.
SourceDerived from 23 native populations of bluebunch wheatgrass from Idaho, Nevada, Oregon, Utah, Washington and British Columbia and the cultivars Whitmar and Goldar.
Breeding MethodGenerated by open- pollinating 23 native populations of bluebunch wheatgrass and the cultivars Whitmar and Goldar. Breeder seed was bulked across the 25 populations in proportion to their seed yield. Therefore, some populations are better represented genetically than others.
Intended UseIntended for use on valley, foothill, and mountain rangelands for re-establishment of native plant communities, vegetative firebreaks, and critical area stabilization and reclamation purposes.
