Abstract: The composition of high molecular weight glutenin subunits (HMW-GS) in 175 hexaploid Triticale from CIMMYT were analyzed using SDS-PAGE method in this experiment. The result showed that the HMW-GS composition of 175 lines were extremely abundant, 3 ,4 and 7 different HMW-GS types were found in the loci of Glu-A1,Glu-B1 and Glu-Rx respectively . The frequency of subunit Null was the highest(49.14%) at Glu-A1 locus, and the second are 1 (30.29%) and 2* (20.57%) .(13+16)was the highest (45.71%) at Glu-B1. The subunits coded by rye chromosome were mainly 21* and 22*. 27 HMW-GS composition types were found ,and among them the frequency of(N,21*,13+16,)(10.29%)、(N,21*,14+15,.22*)(9.14%)、(1,21*,13+16,22*)(8.57%)、(N,21*,7+8)(6.29%)和(1,21*,13+16)(5.71%)was higher.
