The gliadin compositions of wheat grains were genetically determined by polyacrylamide gel electrophoresis. An improved PAGR method was used to determine the electrophoretic patterns of gliadins extracted from 25 wheat cultivars. Most of the cultivars were readily differentiated by their electrophoregrams. Some very closely related cultivars gave identical patterns and were not identifiable by polyacrylamide gel electrophoresis. We have also compared the two electrophoregram patterns extracted by alcohol and by urea. The results show that the differentiation of gliadin patterns is significant among the wheat cultivars.
