摘要: 利用SDS-PAGE和荧光标记检测技术同时对91份黄淮麦区小麦品种(系)的高分子质量麦谷蛋白亚基(HMW-GS)组成进行分析,以期为黄淮麦区小麦品质改良提供理论依据。SDS-PAGE检测结果表明,在Glu-1位点共出现14种亚基类型和28种亚基组合。Glu-A1位点有3种亚基类型,分别是1 (59.34%)、Null (37.36%)、2*(3.30%);Glu-B1位点有5种亚基类型,分别是7+8(52.75%)、7+9(25.27%)、7(12.09%)、13+16(7.69%)、14+15(2.20%); Glu-D1位点有6种亚基类型,2+12(46.15%)、3+12(13.19%)、4+12(8.79%)、5+10(29.67%)、10(1.10%)和12(1.10%)。主要亚基组合类型为1/7+8/5+10(14.29%)、1/7+8/2+12(12.09%)、Null/7+8/2+12(12.09%)。荧光标记检测结果表明,供试材料中含有Ax2*、Dx2、Dx5、Dy10、Dy12的材料分别为3、42、27、28、63份,与SDS-PAGE检测结果相吻合。供试材料品质评分介于5.5~11.0分,平均评分为7.78分,亚基组合Null/13+16/5+10和1/13+16/2+12评分较高,均在10.0分及以上。聚类分析结果表明,供试材料可分为4类,其中第Ⅲ类集中了大部分强筋小麦材料。

Abstract: The high molecular weight glutenin subunit(HMW-GS) composition of wheat varieties(lines) from Huanghuai region was analyzed by SDS-PAGE and fluorescence markers,so as to provide theoretical basis for quality improvement of wheat in Huanghuai region.The results of SDS-PAGE showed that in all 91 wheat varieties (lines) ,a total of 14 types of HMW-GS were detected,including three[Null (37.36%) ,2* (3.30%) ,1 (59.34%)]at Glu-A1,five[7 (12.09%),7 +8 (52.75%) ,7+9 (25.27%) , 13 +16 (7.69%),14 +15 (2.20%)]at Glu-B1 and six[2+12 (46.15%),3+12 (13.19%),4+12 (8.79%),5+10 (29.67%),10 (1.10%) and 12 (1.10%)]at Glu-D1; the main combination types were 1/7+8/5+10(14.29%),1/7+8/2 +12(12.09%),Null/7 +8/2 +12 (12.09%) .The results of fluorescence marker showed that there were 3,42,27,28,63 materials containing Ax2*,Dx2,Dx5,Dy10 and Dy12,respectively,which was consistent with SDS-PAGE result.The quality score ranged from 5.5 to 11.0 with an average of 7.78,and the scores of Null/13+16/5+10 and 1/13 +16 /2+12 were higher,which were equal or greater than 10.0.The results of cluster analysis showed that 91 wheat varieties(lines) were divided into four classes,and class Ⅲ had the most of the strong gluten materials.
