1. The albumin, globulin, prolamin, and glutelin of the protein were obtained by the multiple - step extraction method.

2. Chinese Spring x Dv hybridization. Prolamin genes from Dv and wheat are coexpressed in the ILs and differentially affect bread-making quality.

3. The seed protein were used by 2 protein such as prolamin, glutelin, their 28 alleles and 35.7% diversity were detected.

4. Effect of total protein content on eating quality of rice varied with the relative proportions of glutelin and prolamin.

5. The later the timing of panicle fertilizer application was, the higher the crude protein content and glutelin content of rice endosperm was and the lower the prolamin content of rice endosperm was.
