摘　　要：以SY95-71(1,13+16,5+10)和CH7034(1,14+15,5'+12)重组自交系研究了高分子量麦谷蛋白(HMW-GS)在不同水分条件下对品质性状的影响。结果表明,Glu-1位点各亚基及组合对品质性状的效应受水分条件影响,当Glu-A1为1,Glu-D1为5'+12时,14+15面团形成时间(雨养)和最大抗延阻力(灌溉)明显高于13+16,增幅分别为5.10%和6.16%;Glu-A1位点为1,Glu-B1为13+16时,含5+10亚基的沉降值(灌溉),以及雨养条件下拉伸面积和最大抗延阻力显著高于5'+12;1,14+15,5+10组合对沉降值(雨养和灌溉)和拉伸面积(灌溉)的效应大于1,13+16,5'+12,增幅分别为7.49%、9.54%和10.39%。各组合的蛋白质含量和延伸性、1,13+16,5+10的稳定时间以及1,14+15,5+10的稳定时间和拉伸面积受水分影响较大,1,13+16,5+10和1,14+15,5+10的面包体积在雨养条件下大于灌溉条件下,1,14+15,5'+12和1,13+16,5'+12则反之。研究结果对选育和推广符合当地生产用途和栽培模式的品种具有指导作用。The effects of high molecular weight glutenin subunit (HMW-GS) on quality traits were evaluated using recombine inbred lines (RILs) under different water conditions. Different water regimes influenced effects of subunits at Glu-1 loci on quality traits. Under the same background of 1 at Glu-A1 and 5'+12 at Glu-D1, the 14+15 had more significant effects on the development time under rain-fed and max resistance under well-watered regime than 13+16, with the increase of 5.10% and 6.16%, respectively. The combination of 5+10 had much more significant effects on Zeleny sedimentation under well-water regime and stretch area and max resistance under rain-fed than 5'+12. The effect of (1, 14+15, 5+10) on Zeleny sedimentation was significantly higher than that of (1, 13+16, 5'+12), and the stretch area under well-watered condition had similar trends. The protein content and extensibility of each combination, and the stability time and stretch area of (1, 14+15, 5+10) and the stability time of (1, 13+16, 5+10) were significantly influenced by water conditions, and the performance of other quality traits was relatively stable. Compared with the condition of well-watered, the bread volume of (1, 13+16, 5+10) and (1, 14+15, 5+10) were slightly larger under rain-fed conditions, while (1, 14+15, 5'+12) and (1, 13+16, 5'+12) were opposite. The results of the study have a positive guiding role to select and popularize varieties suitable for production and cultivation at local area.
