To evaluate expression level of HMW-GS protein qualitatively and quantitatively, we separated glutenin fractions and conducted two-dimensional electrophoresis (2DE) in 32 cultivars of Korean wheat for the use of as the basis of wheat breeding. The average spot number of HMW-GS in all Korean wheat cultivars was 11.78 which included 1.31, 5.53 and 4.94 to Glu-A1, Glu-B1 and Glu-D1 loci, respectively. Cultivars harboring 1, 2* subunits had many spots more than ones harboring null allele in Glu-A1 loci because there is no difference of spots between Glu-B1 and Glu-D1 loci. In total spot number of HMW-GS, the highest one was Jokyung as 18 and Dahong the lowest as 7. When the Korean wheat cultivars were compared with the Chinese spring in the average relative expression level, Korean one’s were lower as 0.44. Especially, Gobun was the highest as 1.11 and Eunpa was the lowest as 0.24. Also we investigated phylogenetic relationship based on both frequency of HMW-GS spots and quantification value of each spot to all HMW-GS spots. As a result, Korean the varieties of Korean wheat could be classified into six groups.
