Chromosomes of Triticum aestivum L. homoeologous groups 1 and 6 have genes coding for synthesis of the endosperm gliadin components. A‐gliadin, coded by genes on chromosome 6A, and possibly other gliadins, produce symptoms in humans with celiac disease. It may be possible to eliminate toxic proteins through breeding. As a first attempt, nullisomic 6A‐tetrasomic 6B (N6AT6B) and N6A‐T6D limes of cultivar ‘Chinese Spring,’ which do not produce A‐gliadin, were grown in sufficient quantities for human feeding trials. Both lines produced satisfactory yields of grain for specialty uses. N6A‐T6B was more desirable agronomically and produced less agliadins than N6A‐T6D. Fertility of the N‐T lines was only slightly lower than that of Chinese Spring.
