Abstract:

The paper aims to study the quality of wheat lines in test and to select high quality varieties in recent years. Grey relational analysis was conducted to study 5 characters of 20 wheat varieties in 2016-2018 south Huanghuai winter-wheat region test. The results showed that the two-year relational degree and weight coefficient of the 5 characters were both like unit weight>wet gluten content/ water absorption>content of protein>stability time. The comprehensive evaluation indexes of 5 varieties were higher than the contrast in 2017 and those of 10 varieties were higher than the contrast in 2018.The comprehensive evaluation value of ‘Zhengkemai 136’ was the highest in both the 2 years. Whether or not the weight coefficient was taken into consideration, the annual difference of ‘Luomai 26’ was the smallest among all varieties. The grey relational analysis is of certain scientific value in quality traits evaluation, but is restricted by the few evaluation indexes and the rationality of the weight of each index. In the application of varieties, detailed evaluation according the final purpose is essential, and the grey relational analysis on classified quality traits should be conducted to ensure the accuracy of the evaluation.
