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 634538 | Sebesta Blue-1 | Triticum aestivum L. subsp. aestivum | Oregon, United States | NSGC |  | | 2004 | DEVELOPED | | | | | | Genetic material | Carries a translocated segment of a Thinopyrum chromosome derived from Thinopyrum ponticum (=Agropyron elongatum, 2n = 70). Homozygous for the alien blue-aleurone gene, Ba(b). In crosses with white- and red-seeded wheats, the blue aleurone trait exhibits a strong xenia effect, which is expressed in varing degrees from dark to light blue dependent upon allelic dosage in the 3n endosperm. The original breeding stock was the unregistered genetic stock, Blue Baart, a line developed in the mid-20th century at the University of California, Davis. Awned soft winter wheat genetic stock line (2n=44) with problematic karyotypes due to chromosomal rearrangements in the wheat genome and the presence of two Thinopyrum translocations (probable 4EL and an unidentified Thinopyrum segment). Despite the altered karyotypes, behaves as a stable blue-seeded marker line. Successive generation testing has established that the blue aleurone trait acts as a dominant trait and does not segregate.

The original breeding stock was the unregistered genetic stock, Blue Baart, a line developed in the mid-20th century at the University of California, Davis. Awned hard spring winter wheat genetic stock line (2n=24) with a normal karyotype with a 4EL Thinopyrum segment translocated on the 7AL-wheat chromosome.
