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

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 618816Leymus hybrid-1Leymus hybr.Utah, United StatesW6Not Available2001DEVELOPEDPRE 04/30/2001Breeding materialThree way cross combining genetic material from Altai wildrye (Leymus angustus), Great Basin wildrye (L. cinereus), and mammoth wildrye (L. racemosus). Cross pollinating and behaves meiotically as a segmental autoallopolyploid with multiple copies of the Ns and Xsm genomes from Psathryostachys and an unknown diploid progenitor. In environments where annual precipitation ranges from 400-500 mm, dry matter production exceeded the current Altai wildrye cultivars at mid August by 36% and at late November by 42%. Forage quality lower than the check cultivars throughout the year. However, increased dry matter yields more than compensated in available nutrient levels. Should be utilized as a standing forage for winter grazing.1613726PI 618816
