Abstract

Abstract: Neimai series is one of the representative varieties of middle gluten wheat in the southwest wheat region, with a total planting area of over 3.3 million hm² in Sichuan and surrounding provinces. The composition of high molecular weight glutenin subunit （HMW-GS） in Neimai varieties was analyzed by SDS-PAGE electrophoresis. It was found that the 5+10 high quality subunit in Neimai varieties was positively correlated with the processing quality of wheat with a frequency of 85.7% and a bread score of 7 points. The noodle score of Neimai varieties was higher than that of main varieties. The breeding of wheat varieties containing 5+10 high quality subunits can not only meet the market demand of middle gluten noodle wheat in southwest China, but also contribute to the improvement of wheat quality in China.

Key words: Neimai variety, HMW-GS, 5+10 subunit, flour quality
