In order to provide information for wheat quality improvement based on biotechnology to wheat breeders,the research progresses on molecular breeding of HMW-GS gene were reviewed in the aspects of gene cloning,marker assisted selection(MAS) and gen.

The field experiment was carried out to study the effect of nitrogen and sulfur application on glutenin macropolymer of spring wheat varieties with the same HMW-GS background.

In order to understand the influence of nitrogen application on HMW-GS amount and main quality characteristics of strong gluten wheat cultivar Shannong 12 was used to study the effects of nitrogen fertilization at different stages and amounts on HMW-GS amount and processing quality.
