Establishing Score System of HMW-GS on Dough Consistency Characters of Wheat;

Analysis of Agronomic Characters and HMW-GS in Landrace of Common Wheat;

Composition Analysis of HMW-GS of Some Domestic and Overseas Wheat Germplasms;

N-terminal amino acid sequences were homologous comparing with other High-Molecular-Weight glutenin subunits.

Allelic variation of high-molecular-weight glutenin subunit loci at Glu-1 in bread wheat (Triticum aestivum) new cultivars;

The compositions of high molecular weight glutenin subunits(HMW-GS) in 199 spring advanced lines were analyzed by using SDS-PAGE method.

The foreign genes including gus and 1Dx5 mutant engineered to possess more of the repetitive central domain drived by HMW-GS (high molecular weight glutenin subunits) promoter were introduced into wheat, which allows obtaining the stable expression transplant.

By using SSR molecular marker and high-molecular weight subunits of glutenin SDS-PAGE,the wheat cultivars HeNong822 and 8 character-mutant types obtained from the said cultivars induced by EMS,such as dwarf,awnless,dense panicle,clubbed panicle and early flower,were identified.

The result indicated that maxium height of extensogram could reflect the gluten intensity objectively, but the experiment of extensogram reqaired to use 300 g flour at least; HMW glutenin subunits composition of wheat cultivars were controlled by gene, half of one wheat kernel was enough to finish the experiment.

Second filial generation populations of two crosses made by parents containing different HMW glutenin subunit composition were used to study the relations between subunit combina-tions and their protein content, dry gluten content, wet gluten content, Zeleny sedimentation value.

The differences of several quality characters of HMW glutenin subunits in second filial generation of bread wheat were studied by using two single cross combinations.
