Abstract: The high molacular weight(HMW) subunit composition of glu-tenin was analysed by SDS-PAGE in 611 local varieties of the common wheat(T. aestivum L.), and triticum varieties different to the local varieties were also analysed by their electrophoretograms. The results showed that there were only few simple composition types for HMW subunits. Glu-Ale, Glu-Bib and Glu-Dla, accounting for 97.1%, 80.7% and 90.5% respectively, were superabundant, and the varieties with these alleles were generally bad in baking quality. Some novel variants were found including Glu-Blaj(coding only subunit 8) and Glu-Dlk(coding only subunit 2). This suggested that the local varieties belonged to a special wheat group. According to the electrophoretograms, the triticum varieties different to the local varieties were considered to belong to the same genotype and were highly similar in heredity.
