摘　　要：利用SDS-PAGE方法对源于CIMMYT的六倍体普通小麦材料SYN351进行了高分子量谷蛋白亚基(HMW-GS)分析,结果表明SYN351Glu-A1和Glu-B1位点编码的HMW-GS同时全部缺失,唯有Glu-D1位点编码的HMW-GS(5+10)存在(N,N,5+10),是六倍体普通小麦中一种高分子量谷蛋白亚基缺失的新类型。The composition of high molecular weight （HMW） glutenin subunit （GS） in a common wheat line SYN351 derive from CIMMYT wheat germplasm,was analyzed by SDS-PAGE. SYN351 only possessed HMW-GS 5 ＋ 10 encoded by Glu-D1 ,and non HMW-GS were observed on locus of Glu-Aland Glu-B1. It was seemed that SYN351 （ N, N ,5 ＋ 10） was a new type of HMW-GS composition in common wheat. The potential utilization of SYN351 in wheat quality breeding was discussed in present paper.
