| 1 | PI 649935 | Great Northern Germplasm | Achillea millefolium L. | Montana, United States | W6 | | Not Available | 2005 | COLLECTED | 1988 | Flathead county, Montana. Section 27 and 28, Township 32N, Range20W. Located along USF2 Road 5271, off Canyon Creek road 316 the cutoff to McGinnis Creek Road | 49.46666667, -114.16666667 | 1100 | Slope 0-30%, Exposure South-Southwest, 28-30 inches precipatation, greavelly soil, cut and fill slopes | Wild material | Great Northern western yarrow is a native, herbaceous perennial in the Aster Family. It is a very common wildflower that grows erect from creeping rootstocks, to a height mostly 25 to 90 cm tall. The leaves are lacy and fern-like in appearance, as they are finely dissected into numerous, short and narrow divisions not over 1 mm wide--millefolium means a thousand leaves in Latin. The basal foliage is up to 25 cm long, with leaves along the flowering stalk longest at the base and progressively shorter up the stem. The entire plant is densely covered in long, soft, wooly hairs. The plant has a very distinctive aroma, similar to chamomile or dog fennel, and is especially noticeable when crushed. It is a self-incompatible, insect-pollinated species, with an inflorescence arranged in a compound, flat-topped corymb 6-20 cm wide, consisting of small, numerous, flower heads 4-6 mm in size. Involucre bracts are pubescent and greenish, with straw-colored papery margins. Outside ray-flower numbers are 3-12, mostly white to cream-colored, 1-2.5 mm long, and encircle the center disk-flowers. The disk-flowers number 10-75 each, and are yellow, tubular, perfect, and seed-producing. The terminal clusters of flower heads are normally white to cream-colored and have an extended bloom period from May to September. The extremely small fruit is a whitish, flattened achene, with compressed margins that are grayish in color. There are approximately 10 million seeds per kilogram. Great Northern western yarrow exhibits good survival in droughty conditions on gravelly loam and thin or sandy soils. It is an early successional species that readily establishes on disturbed sites, such as shallow, silty, shallow to gravel, and silty steep. Great Northern Germplasm is adapted for use in northern Idaho, and all of Montana and Wyoming, except the Red Desert and Bighorn Basin. Great Northern Germplasm was selected primarily to add species diversity in seed mixtures for rehabilitation of disturbed sites such as rangelands, minelands, roadsides, park and restoration areas, prairie reconstruction projects, and farm bill program conservation plantings. Secondary use is for ornamental application in low maintenance or naturalized landscapes. | 1685537 | PI 649935 |
| 2 | PI 639271 | Yakima | Achillea millefolium L. | Utah, United States | W6 | | Not Available | 2005 | DEVELOPED | PRE 05/25/2005 | | | | | Breeding material | Developed and released as a source identified class germplasm by a multi-agency project to identify resilient plant characteristics and develop wear-resistant plant cultivars for use on military training lands. This is a multi-origin germplasm assembled from 27 locations to ensure establishment over a broad geographic area and provides a source of readily available seed. Has shown vigorous growth in the G1 field near Logan, Utah and has been successfully established in field trials in Utah, Idaho, and Washington. A range of phenotypic differences have been observed in the seed production field indicating the diversity within this germplasm. In a preliminary study an earlier western yarrow collection from many of the same 27 collection locations was tested at the Yakima Training Center where it established and persisted better than common variety-not-stated western yarrow. Western yarrow is an important, abundant forb in the bluebunch wheatgrass-sagebrush plant communities of the Intermountain and Northwest regions of the United States. It is rhizomatous and drought tolerant enabling it to recruit into disturbed areas and often competes well with invasive weedy species. This western yarrow is intended for use in rehabilitation and restoration of western rangelands. It should be particularly useful to help stabilize and add diversity to severely disturbed sites, such as military training lands and after wildfires. | 1677385 | PI 639271 |
