A collection of new and obsolete Iranian bread wheat cultivars were characterized for gliadins using acid polyacrylamide gel electrophoresis (A-PAGE). Extensive polymorphism (H) = 0.734 in gliadin patterns was found. A total of 26 band patterns including 13, 8 and 5 different mobility bands were identified, in the zones of omega-, beta + gamma- and alpha-gliadins, respectively. There were a few patterns specific to each region and some were common among all the regions. Patterns of alpha-gliadin C, beta + gamma-gliadins A, and omega-gliadins H, C and E patterns were significantly higher in temperate and tropical zones beta + gamma-gliadin C and omega-gliadin Q were significantly higher in Caspian-cold regions. Variation was observed in gliadins patterns of cultivars grown in different regions in Iran. Individual cultivars showed unique gliadin fingerprints. There were larger variation in omega- and gamma + beta-gliadins than in alpha-gliadins. These results may provide complementary information for relating genetic diversity, and quality characterization of Iranian wheat cultivars.
