Narrative
Intended to provide genetic diversity within a single germplasm for semi-arid to mesic sites where bluebunch wheatgrass was an original component of the vegetation. Its broad genetic base was generated by open-pollinating 25 native-site populations from Washington, Oregon, Nevada, Utah, Idaho, Montana, and British Columbia. Twenty-four of the constituent populations are diploid (2n=14) and one is tetraploid (2n=28). Two of the populations are the cvs. 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. AFLP molecular markers have received significantly more genetic diversity within P-7 relative to Whitmar and Goldar.
