QIN Jiang-min~1,LU He-ping~2,LI Jia-min~1,GE Chang-bin~1,XU Ru-hong~1,ZHANG Qing-qin~1(1.Research Center of Wheat,Guizhou University,Guizhou Guiyang 550025,China;2.College of Animal Science and Technology,Northwest A&F University,Shanxi Yangling 712100,China)  
The compositions of high molecular weight glutenin subunit of 108 wheat materials were studied with the method of SDS-PAGE.The results showed that the HMW-GS compositions of 108 wheat materials were extremely(abundant.) 15 subunit patterns and 26 subunit combinations were detected.At the Glu-A1 loci,frequency of subunit 1 was the highest(59.3%),at the Glu-B1 loci,frequency of subunit(7+8) was the highest(27.8%),at the Glu-D1 loci,frequency of subunit(2+12) was the highest(68.5%),frequency of subunit(5+10) was 17.6%.In analysis of wheat lines the special subunit(6~*+8~*) was also observed.
