Abstract:

This experiment explored the fluctuation trend of winter wheat quality index among different years in Huang-huai area, aiming to provide certain reference for the improvement of wheat quality and industrial application of varieties in this area. A total of 317 winter wheat cultivars, originated from the nation wheat regional trial in irrigated land from 2011 to 2015, were taken as the materials to analyze the grain quality index such as crude protein content, wet gluten content and stabilizing time, sedimentation value and maximum resistance. The results showed that the crude protein content and wet gluten content of wheat cultivars in the southern and northern parts of Huang-huai area in 2013 were averagely higher than that in other years, but the stabilization time was not the highest. Comparing these wheat quality traits in different years comprehensively, the variation of the testing weight was the least, but that of the stabilization time was the largest. The variation of protein content and wet gluten content was similar to each other, while the dough stabilization time was up to twenty times as much as the former two. According to these quality indicators, the strong, medium and weak gluten-strength wheat cultivars accounted for 3.15%, 0% and 22.7%, respectively, and the proportion of the remaining unclassified cultivars is as high as 74.14%.
