摘　　要：【目的】研究新疆小麦品种面粉色泽(白度)的变异及其影响因素,为提高新疆小麦品种的面粉白度及选育具有优良面粉色泽的小麦品种提供参考。【方法】以新疆小麦育成品种和自育成品种(系)为材料,研究新疆小麦面粉白度的分布规律;以37个新疆不同品质类型的冬小麦品种(系)为材料,分析小麦相关品质性状与面粉白度和色泽的相关性及影响。【结果】71份新疆小麦品种资源的面粉白度平均值的分布范围较大,筛选出13份面粉白度值超过80的小麦种质;面粉的吸水率、籽粒硬度与白度呈极显著的负相关,籽粒硬度、吸水率、淀粉含量和延伸度共同决定了面粉白度变异的63.3%。籽粒蛋白质含量与面粉白度相关性不显著,仅与面粉色泽红度(a*值)呈极显著正相关。【结论】新疆小麦育成品种和自育成品种(系)中高白度种质少。【Objective】Variation of flour color(whiteness)of Xinjiang wheat varieties and its influencing factors,to improve the flour whiteness of Xinjiang wheat varieties and provide theoretical reference for breeding wheat varieties with excellent flour color in Xinjiang wheat breeding job in the future.【Methods】In this study,Xinjiang wheat cultivars(lines)were used as materials to understand the distribution law of wheat flour whiteness in this region and then 37 winter wheat varieties(lines)of different quality types in Xinjiang were used as materials to preliminarily explore wheat related quality traits.【Results】The average distribution range of flour whiteness of 71 Xinjiang wheat variety resources was large,and 13 wheat materials had whiteness values higher than 80;The water absorption rate,grain hardness of flour and whiteness were extremely significantly negatively correlated,and grain hardness,water absorption,starch content and elongation jointly determined 63.3%of flour whiteness variation.There was no significant correlation between grain protein content and flour whiteness,but a very significant positive correlation with flour a*value.【Conclusion】There are few germplasms of medium and high whiteness in Xinjiang wheat cultivars(lines).
