The Application Conditions of Whole Wheat Flour Gluten Index in Wheat Breeding

[Objective]In order to determine the qualities of small samples of wheat varieties more flexibly and conveniently,this research replaced the flour gluten index by whole wheat flour gluten index.[Method] This study selected ten experimental materials of high,medium and low gluten type wheat varieties which suitable for growing in the south of Shanxi Province.The correlations between the whole wheat flour gluten index(wheat gluten index) and the flour sedimentation value,as well as the stability time under different temperatures and humidities were observed.And the correlation between wheat gluten index and flour gluten index was also analyzed.[Result] The results showed that the wheat gluten index determination was optimal at 20 ℃ and humidity around 50%.Under this conditions,the wheat gluten index and flour gluten index were highly correlated,as well as the wheat wet gluten content and flour wet gluten content,both correlation coefficients were above 0.9.[Conclusion] So the wheat gluten index method was feasible in the application of wheat breeding,storage and food processing,etc.
