Abstract：In order to investigate the quality of new wheat lines from Henan province and to provide refer-ence for wheat quality breeding,HMW-GS compositions of 722 materials were analyzed by SDS-PAGE. 12 HMW-GS alleles and 20 subunit combinations were detected. The subunits 1(60.94%),7 +9(65.93%),2 +12(57. 34% ) were the major subunits on locus Glu-A1,Glu-B1 and Glu-D1 respectively. Subunit combi-nations “1,7 + 9,2 + 12”(21. 88% ) and “Null,7 + 9,2 + 12”(20. 22% ) were the major subunit com-binations. The result showed that HMW-GS allelic variation and subunit combination had rich diversity, but the frequency of different alleles had great disparity. So the frequency of quality subunit combinations and the quality subunits 7 + 8 and 14 + 15 need to be improved in future.
