Abstract: In order to make good use of foreign varieties, and to reallize the genetics base ,especially the quality traits of these introduced materials.HMW-GS compositions of 102 wheat cultivars from Russia and middle Asia area were analyzed by SDS-PAGE. The results showed that the number of allelic variations was eleven. At Glu-A1 locus, three alleles were detected, which encoded subunit 1, 2*and Null respectively and the major subunit was Null with the frequency of 40.20%;At Glu-B1 locus, five alleles were detected, which encoded7、7+8、7+9、6+8、17+18, the 7+9 was the major subunit pattern(59.80%). At Glu-D1 locus, there were three alleles which encoded 2+12 、2+12’ and 5+10 respectively were detected, and there are 51.96% materials took the subunit 5+10. Sixteen subunit combination patterns were identified and the major pattern was “Null, 7+9, 2+12”with the frequency of 25.5%.It is worth mentioning that there were twenty one cultivars with the score of 10 and twenty nine varieties with the score of 9 according to Payne’s scoring system.It was showed that these materials may be a promising resource for improving the bread-making quality of wheat in China.
