Abstract

Abstract: Near-isogenic lines of HMW glutenin subunits 2+12 and 5+10 of cultivar Longmai 15 were obtained by analysis of morphology, SDS-PAGE and A-PAGE.The Zeleny sedimentation of Longmai 15 with 5+10 subunits is 4.5ml(12%) higher than Longmai 15 with 2+12 subunits.Ratio of Zeleny sedimentation and wet gluten is increased from 1.08 to 1.32.The results indicated that 5+10 subunits is better than 2+12 subunits in flour quality.

Key words: Wheat, near-isogenic line, glutenin subunits, flour quality
