Abstract: 【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).
