摘　　要：利用SDS-PAGE技术对385份CIMMYT种质进行高分子量麦谷蛋白亚基组成分析。结果表明:Glu-A1、Glu-B1、Glu-D1位点上变异类型丰富,共存在11亚基与24种组合类型,优质亚基出现的频率非常高,Glu-A1位点上的1亚基的频率达到了33.5%,Glu-B1优质亚基7+8出现的频率11.2%,Glu-D1位点优质亚基5+10出现的频率达到81.3%。评分在7分以上的材料达37.8%,23个材料评分在9分以上,高分子量麦谷蛋白亚基的平均得分7.08分。通过在这些材料中选取评分较高的与贵州小麦进行杂交,可有效提高贵州小麦品种的产量与品质。The high molecular weight glutenin subunit （HMW-GS）of 385 cimmyt germplasms was analyzed by SDS-PAGE which were planted in Guizhou. The results showed that there were 11 kinds of subunits and 24 combination types in Glu-1 locus of cimmyt wheat germ plasms. 1 subunits on Glu-A 1 reached 33.5% ,7 ＋ 8 subunits on Glu-B 1 reached 11.2% ,5 ＋ 10 subunits on Glu-D 1 reached 81.3%. The quality score over 7 reached 37.8% ,and 23 germplasm quality score over 9 ,and its average score was 7.08. The wheat with high quality score could be used in wheat breeding to increase yield and quality of Guizhou wheat variety.
