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

| 0 | PI 682089 | U6714-B-056 | Triticum aestivum L. subsp. aestivum | Michigan, United States | NSGC |  | | 2017 | DEVELOPED | | | | | | Breeding material | To broaden the genetic base for resistance to powdery mildew in wheat, germplasm lines U6714-A-011 and U6714-B-056 were developed at Michigan State University and are fixed for the novel powdery mildew resistance gene Pm58. This gene was identified in Aegilops tauschii Coss. accession TA1662, introgressed, and mapped to wheat chromosome 2DS. The two germplasm lines described are BC2F4-derived inbred backcrossed lines from a direct cross between TA1662 and the recurrent wheat parent KS05HW14, a hard white winter wheat line adapted to western Kansas. In addition to exhibiting resistant reactions to multiple Bgt isolates with broad virulence profiles, both lines have moderate yield potential and good agronomic characteristics, making them suitable as breeding germplasm. | 1949925 | PI 682089 |
