Allele compositions at Glu-1 loci coding for high-molecular-weight (HMW) glutenin subunits in 58 common (bread and biscuit) wheat cultivars and IO durum wheat cultivars registered in Canada were determined by SDS-polyacrylamide gel electrophoresis. Nineteen different compositions were found in the common wheats and three in the durum wheats. Most common wheats have one of two compositions and all but two durum wheats contain the same Glu-1 composition. Therefore the variation in the HMW g)utenin subunit compositions is of limited value for cultivar identification compared with gliadin polymorphism. Nine cultivars were found to consist of two biotypes with different alleles, and five cultivars contained unusual alleles previously uncatalogued; two unique alleles were found in old Canadian cultivars. The results are discussed in relation to gluten quality and possible strategies for developing new cultivars with good technological characteristics.
