Molecular study of high molecular weight glutenin subunits in Iranian wheat

The high molecular weight glutenin subunit (HMW-GS) compositions of 154 Iranian bread wheat landraces were determined by sodium dodecyl sulphate polyacrylamide gel electrophoresis (SDSPAGE). Seeds were obtained from the Field Crops Research and Genetic Resources Unit of the Faculty of Agriculture، University of Tehran. The Iranian bread wheat landraces divided into 14 groups based on allelic compositions and 12 alleles were detected. The genetic diversity of Glu-B1 locus (0. 274) was the highest compared to others loci. The Glu-1 loci score ranged from 4-10. The Most frequent HMW-GS compositions were N، 7+8 and 2+12. By studying the allelic diversity of high molecular weight glutenin subunits (HMW-GS)، characterization of genetic resources and quality of wheat varieties can be done for improving the bread-making quality of hexaploid wheat.
