中文摘要：
为给小麦品质育种提供参考信息,选用我国18份有影响的优质面条和面包小麦品种或种质资源，通过分步法SDS-PAGE和改良A-PAGE分析了其Glu-1、Glu-3、Gli-1位点的基因变异特点。结果表明，由Glu-1住点控制的高分子量谷蛋白亚基共14种图谱，其中，Glu-A1位点上优质亚基1和2^＊分别占61．1％和11．1％，Glu—B1位点上优质亚基14＋15、7＋8、17＋18、13＋16分别占27．8％、27．8％、22．2％、5．6％．Glu_D1位点上优质亚基5＋10占55．6％。Glu—A1、Glu—B1、Glu-D1位点上均为优质亚基的品种（系）有陕451（1，7＋8，5＋10）、95鉴5104（1,14＋15，5＋10）、陕优412（2^＊，7＋8，5＋10）、绵阳89-47（2^＊，13＋16，5＋10）以及中优16、冀5099、绵优1号、绵优2号（1，17＋18,5＋10），占参试品种的44．4％。由Glu-3位点控制的低分子量谷蛋白亚基共12种图谱，小偃6号、PH82-2、陕253、80356、95鉴5104、郑农33等6个品种皆为“a，d，c”；由G1i-1位点控制的醇溶蛋白共12种图谱，小偃6号、PH82-2、陕优225、陕253、80356、中优16、95鉴5104等7个品种皆为“O，new，i”，即发现在Gli-B1位点是一个新等位基因。
英文摘要：
The banding patterns of HMW-GS, LMW-GS and HMW gliadins of 18 quality wheat cultivars （lines） were analyzed using two-step SDS-PAGE and a modified A-PAGE to provide information for wheat quality breeding. 14 HWM-GS band patterns were encoded by Glu-1 locus, 61.1% and 11.1% of them were 1 and 2^＊ in Glu-A1 , 27.8%,27.8%,22.2% and 5.6% of them were 14＋15, 7＋8, 17＋18, 13＋16 in Glu-B1, 55.6% of them were 5＋10 in Glu-D1, respectively. Cultivars with positive subunits in all three Glu-1 locus are Shaan 451（1, 7＋8, 5＋10）, 95Jian5104（1,14＋15, 5＋ 10）,Shaanyou 412（2^＊ , 7＋8, 5＋10）, Mianyang89-47 （2^＊ , 13＋16, 5＋10）, Zhongyou16, Ji5099, Mianyou 1 and Mianyou 2 （1, 17＋18, 5＋10）, and were about 44.4% of the tested cultivars. 12 LMW-GS band patterns were encoded by Glu-3 locus. The patterns of 6 Cultivars of Xiaoyan 6, PH82-2, Shaan 253, 80356, 95Jian5104 and Zhengnong 33 were the same （a, d, c） at Glu-1. 12 HMW gliadin band patterns were encoded by Gli-1 locus, the patterns of 7 Cultivars of Xiaoyan 6, PH82-2, Shaanyou 225 , Shaan 253, 80356, Zhongyou 16 and 95Jian5104 were the same （o,new,i）, two new patterns at Gli-B1 locus were discovered which were different from the linked pattern h of dencoded by Glu-B3 of other cultivars.
