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

0PI 659317CO03752Triticum aestivum L. subsp. aestivum Colorado, United StatesNSGCImageNot Available2010DEVELOPEDGenetic materialWheat-rye addition lines carrying resistance to the biotypes 1 and biotype 2 of Russian Wheat Aphid (RWA). Resistance was derived from PI 386148 Russian triticale, backcrossed five times into the background of Lamar wheat (PI 559719). The progenies were tested for RWA reaction for at least eight generations. These six lines from these selections were identified for their resistance to the RWA and their seeds were increased for agronomic and other characterizations. CO03752, CO03758, CO03761, and CO03765 are cytologically stable and carry a pair of rye (Secale strictum C. Presl) chromosomes as disomic addition lines of 1R. CO03764 carries 42 wheat chromosomes and two heteromorphic 1R chromosome products. CO03754 is cytologically unstable and shows a moderate level of mixoploidy with monosomic additions of 1R. One rye chromosomes, 1R from the donor species contains genes for RWA resistance. [See PI 659317-659322 for accessions from the same J Pl Regis citation.]1835018PI 659317
