Abstract The allelic diversity in seed storage proteins of 25 bread wheat cultivars grown in Hellas was investigated. In total, 15–20 seeds per cultivar were used for the determination of the alleles present at the loci coding for high‐molecular‐weight glutenin subunits and gliadins. For this purpose, acid polyacrylamide gel electrophoresis for gliadins and SDS‐electrophoresis for glutenins were employed. Analysis of the electrophoretic patterns revealed that intravarietal selections obtained from the cultivar ‘Nestos’, together with the cultivar ‘Eurydice’ which was selected from the cultivar ‘Nestos’, were identical to their original cultivar and to the cultivar ‘Dodoni’. The cultivars ‘Penios’, ‘Siette Cerros E’, ‘Gorgona’ and ‘Louros’, although recorded to differ in descent, were found to be identical at all the loci examined. Finally, it was revealed that four of the Hellenic cultivars carry the wheat‐rye 1BL/1RS translocation. These data could be beneficial for a better understanding of the existing differences in quality and stress‐resistance between the cultivars examined.
