摘要: 为了明确小麦高分子质量谷蛋白亚基(HMW-GS)与加工品质的关系,以来源于国内外不同种植区的148个小麦种质为材料,研究小麦HMW-GS的多样性及其与小麦粉和馒头加工品质的关系。结果表明,参试材料在Glu-A1、Glu-B1、Glu-D1 3个位点分别检测到3,7,7种不同的亚基类型,1、7+9、2+12亚基在各自位点上出现的频率均最高,分别为56.8%,47.3%,45.9%;亚基组合类型共有35种,其中,(1/7+9/2+12)、(1/7+8/5+10)、(N/7+9/2+12)、(1/7+9/5+10)组合出现频率较高;不同来源小麦种质的HMW-GS组成存在一定差异,国外引进种质和黄淮冬麦区种质的亚基类型较丰富,且优质亚基出现的频率较高;1、2*、7+8、17+18、5+10亚基对面筋强度具有明显的正向效应,2*、17+18、2+10亚基对馒头的硬度和咀嚼性具有重要影响,携带(1/14+15/2+12)、(1/7+9/5+10)、(N/7+8/2+12)亚基组合种质馒头的加工品质较好。

Abstract: In order to clarify the relationship between high molecular weight glutenin subunit (HMW-GS) and wheat processing quality,148 wheat germplasms from different regions of the world were used to study the genetic diversity of high molecular weight glutenin subunits(HMW-GS) and its relationship with the quality of flour and steamed bread. Results showed that the tested materials had abundant polymorphisms at the three gene loci of Glu-A1, Glu-B1 and Glu-D1, of which, three, seven and seven types of subunits were detected, respectively. The highest frequency of allele was 1, 7+9 and 2+12 at each of the three loci, which accounted for 56.8%, 47.3% and 45.9%, respectively. A total of 35 HMW-GS combinations were identified in the tested materials, among which the combinations of(1/7+9/2+12), (1/7+8/5+10), (N/7+9/2+12) and(1/7+9/5+10) had higher frequencies. The compositions of HMW-GS were different in wheat varieties(lines) from different regions. Moreover, the most abundant type of subunit and the highest frequency of high-quality subunit were found in germplasms from aboard and Huanghuai winter wheat region. Furthermore, subunits 1, 2*, 7+8, 17+18 and 5+10 had positive effects on gluten strength, while subunits 2*, 17+18 and 2+10 had important influence on hardness and chewiness of steamed bread. The genotypes with combination forms of(1/14+15/2+12), (1/7+9/5+10) or(N/7+8/2+12) had good processing quality of steamed bread.
