摘　　要：为了解小麦新品种高分子量谷蛋白亚基的组成及变化趋势,采用SDS-PAGE电泳技术,对177个小麦DUS测试品种及近似品种进行了高分子量谷蛋白亚基分析。结果表明,申请品种和近似品种中高分子量谷蛋白亚基存在着较丰富的变异,在三个位点上共检测出12个变异类型,发现共有17个不同的亚基组合类型。与以往研究不同的是,其中优质亚基出现的频率较高。In order to know the changing trend and composition of high molecular weight glutenin subunit （HMW- GS）, 177 wheat applicant varieties suits showed that there were lots of variations leles were detected at 3 loci and 17 subunit and reference varieties were analyzed by SDS -PAGE. The re- in applicant varieties and reference varieties. In total, twelve al- combinations were identified. Compared with previous studies,high -quality subunits appeared more frequently.
