摘　　要：[目的]了解小麦-簇毛麦T6VS·6AL易位染色体对衍生高代品系的品质效应,为山西中部麦区培育含抗白粉病基因Pm21的优质、高产小麦新品种提供科学依据。[方法]采用MPA傅里叶变换近红外光谱仪分析了70个含纯合6VS·6AL易位染色体的小麦高代品系及8个相应亲本的蛋白质含量、湿面筋含量和沉降值。[结果]绝大多数高代品系的蛋白质含量、湿面筋含量和沉降值低于双亲,说明T6VS·6AL易位染色体对上述3个品质性状有一定的负向效应。参试T6VS·6AL高代品系的蛋白质含量、湿面筋含量和沉降值在不同组合间表现趋势不一致,而且同一组合的不同品系之间存在着显著差别。[结论]在组合配置时要考虑亲本的影响,同时注重对品质性状的早代选择。[Objective]In order to understand the effects of the wheat-Haynaldia villosa T6VS·6AL translocation chromosome on quality characters of wheat,and to provide scientific basis for breeding high-quality and high-yield wheat varieties with powdery mildew resistance gene Pm21 in central Shanxi Province. [Method]Seventy wheat advanced lines carrying T6VS·6AL chromosome and eight corresponding parents were analyzed for quality characters including protein content,wet gluten content and sedimentation value by MPA Fourier transform near infrared spectrometer. [Result]Grain protein content,wet gluten content and sedimentation value of most advanced lines were lower than those of parents,indicating that T6VS·6AL translocation chromosome had some negative effect on the above three quality traits. The protein content,high generation strains of wet gluten content and sedimentation value of advanced lines showed inconsistent trend in different crosses,and significant difference occurred for three quality traits among strains of the same cross. [Conclusion]During parent selection and early generation selection of quality traits,we should be pay attention to wheat powdery mildew resistant breeding.
