Select the tab for the type of search. Each tab has everything you need to do to perform that type of search.

(Results of more than 500 will not return images.)

This search will show only accessions that have material that may be requested, including those not seasonally available.
You may list accessions with separators (commas or semicolons, as shown below) or by entering them on separate lines, such as
PI 651794
PI 651649
PI 651650
When searching a range of accessions, use the Advanced Search tab with the Accession Identifier Range criterion.

The more information you provide, the better the search will be.

0PI 633741FISH CREEKElymus elymoides (Raf.) Swezey subsp. elymoides Idaho, United StatesW61998DEVELOPEDPRE 09/1998Wild materialCollection from a site classified by USDA-NRCS as Major Land Resource Area B10 (Upper Snake River Lava Plains and Hills). Estimated average annual precipitation at the site is 380 mm based on extrapolation from official weather stations at Picabo (20.00 km to the southwest) and Craters of the Moon National Monument (23.75 km to the northeast). Removal of the awn without resultant seed damage has been problematic in Sand Hollow big squirreltail germplasm. Mass of the proximal centimeter of the awn was 0.272 mg at Evans Farm,(Millville, UT) in 2001, 33% lower than Sand Hollow. The less robust awn makes the seed more amenable to debearding. Spike disarticulates in a determinate fashion at the base, unlike most E. elymoides ssp. elymoides accessions that disarticulate indeterminately at each rachis internode.1563693PI 633741
