Abstract: The changes of the contents of grain protein and its fractions and SDS-sedimernation value from 14 cultivars in wheat of Mianyang, and the relaionships of the contents of grain protein and its fractions with SDS-sedimentation were studied. The aim was to provide the theoretical evidence for wheat improvement of Mianyang. The results showed that the grain protein contents in the different cultivats were different. The range of grain protein content was from 7.30% to 13.09%. Most of eultivats belonged to the type of low protein content.The range of SDS-sedimentation value in most of cultivars was from 20 to 30 mL. The content of grain protein fractions in all cultivars were different. The relationships of grain protein content and storage protein content and gluten in content and gliabin content with SDS-sedimentation value were signfficantly positive. The high contents of storage protein and glutenin and gliabin were the basis of obtaining the high baking quality in wheat of Mianyang.

Key words: Wheat, Grain protein content, Protein fractions, SDS-sedimentation value
