The composition of high molecular weight glutenin subunits of genetic resources of bread wheat and their relationship with bread-making quality


, : The composition of high molecular weight glutenin subunits of genetic resources of bread wheat and their relationship with bread-making quality. Scientia Agricultura Sinica 28(Supplement): 22-27

SDS-PAGE was used to determine the high molecular weight (HMW) glutenin subunit composition of 5071 wheat accessions over a 3-year period. A total of 118 types of subunit composition were identified, of which 90 were present in the Chinese entries. The good quality subunits 5 + 10 were observed in 15.7% of Chinese entries and 45.9% of foreign entries. Subunits 2, 5, 8, 10 and 12 were usually closely linked with another subunit, but in several entries they occurred alone.
