摘　　要：为给小麦品质改良提供理论依据,选用不同品质类型的3对Glu-D1位点变异的近等基因系为材料,研究Glu-D1位点麦谷蛋白亚基变异对小麦谷蛋白大聚合体(Glutenin macro polymer,GMP)含量的影响及品质变化情况。结果表明:Glu-D1位点近等基因系间5+10亚基类型GMP含量明显高于2+12或3+12亚基类型GMP含量,3对近等基因系平均增加24.23%。GMP含量在与面粉加工品质的关系上,同一品种不同亚基类型间随着GMP含量的增加,干湿面筋含量、Zeleny沉降值、稳定时间、抗延阻力及拉伸面积等均有不同程度的提高,其中与Zeleny沉降值、抗延阻力及拉伸面积等关系最为密切。同时讨论了GMP含量作为小麦品质评价指标的可能性。Three pairs of near-isogenic lines（NILS） of wheat involving variable Glu-D1 locus were used to study Glu-D1 locus of variable glutenin subunits result in GMP content and flour quality change.The results showed that the GMP content of 5＋10 subunits were significantly higher than that of the 2 ＋12 or 3＋12 subunit type,three pairs of near-isogenic lines increased by an average of 24.23%.The relationship between GMP content and flour processing quality,protein content,dry and wet gluten content,zeleny sedimentation value,stabilization time,resistance against extension and extension area was positive correlation,and closely related with zeleny sedimentation value,stabilization time,resistance against extension and extension area.But the effect on sedimentation was little.
