Sebesta Blue-2 LINK Triticum aestivum habit = Springstatus = Breeding/research material order = available | # PI 634539 @ USDA-ARS (USA) INFO > GRIS | United States, Oregon (developed) | other # = GRIS{PI-634539} | Remark: 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. Awnless soft winter wheat (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.
