The objective of the present study was to characterize the high molecular glutenin subunits (HMW-GS) composition and the presence of 1B/1R translocation in newly developed wheat (Triticum aestivum L.) germplasm, which have one or more traits that are useful in wheat improvement. Sodium dodecyl sulphate polyacrylamide-gel electrophoresis (SDS-PAGE) and acid polyacrylamide-gel electrophoresis (A-PAGE) were used to detect HMW-GS composition and the presence of 1B/1R wheat-rye (Secale cereale L.) chromosome translocation in the wheat germplasm. Bread-making quality scores of these lines were determined. A high level of variations in HMW-GS encoded by Glu-1 locus was observed. Sixteen major HMW-GS, with 30 combinations, were detected. The percentage of cultivars with more than two desirable subunits was 38.7%. Thirteen cultivars had bread-making quality scores of 10 in combination with one or two desirable agronomical traits, such as high-yield potential, dwarfing stem, resistance to diseases, and/or tolerance to abiotic stress. Sixty-eight (36.6%) cultivars possessed IBIIR translocation. The newly developed germplasm with HMW-GS for good quality can be promising resources for improving bread-making quality of wheat. |
