摘　　要：为了给小麦品质遗传改良提供参考,对59份CIMMYT春小麦材料的HMW-GS组成及其品质状况进行了分析。结果表明,供试材料中Glu-A1上的HMW-GS有3种类型,分别是1、2*和null,其中1出现的频率最高,为44.07%;Glu-B1位点有9种类型,其中6+8和14+15出现的频率最高,分别是37.29%和32.20%;Glu-D1位点有11种类型,其中10亚基出现的频率最高,为25.42%。总共检测到33种HMW-GS组合变异类型,其中1/14+15/10出现频率最高,为10.17%。59份CIMMYT春小麦材料的综合品质均较差,不适合直接推广,但有些优质亚基出现的频率较高,因而可以作为改善我国春小麦现有品种亚基组成状况的亲本材料加以利用。In order to provide information for wheat quality improvement,the composition of High-Molecular-Weight Glutenin Subunits(HMW-GS) and the quality properties of 59 CIMMYT spring wheat lines were investigated.The results indicated that three kinds of HMW-GS,including subunit 1,2* and null,were detected at Glu-A1 locus,and the frequency of subunit 1 was the highest with 44.07%.There were 9 kinds of HMW-GS at Glu-B1 locus,and the frequencies of allelic combination 6+8 and 14+ 15 were 37.29% and 32.20%,respective...
