| Outline of Final Research Achievements |
Celiac disease is a serious disorder where the ingestion of gluten leads to damage in the small intestine. The major antigens of celiac disease are gamma gliadin on chromosome 1D and alpha gliadin on chromosome 6D. The purpose of this study was to create bread wheat lines that lack both parts of chromosomes 1D and 6D where the genes for gamma and alpha gliadins are located, respectively. In this study two chromosome partial deletion lines, 1DS-5 and 6DS-4 were selected to make F1 between them, and then F2 progeny was obtained. By chromosome observation and PCR analysis, one plant was confirmed to be homozygous for both 1DS-5 and 6DS-4. This plant was propagated to establish double deletion lines lacking both gamma and alpha gliadins.
