| This paper investigates the grain protein content, hard, Zeleny sediment, grain color, swelling index of glutenin(SIG), and flour swelling volume(FSV) of 47 wheat varieties (lines), analyzes the correlativity of the wheat qualities and categorizes the wheat varieties (lines). The result shows that the average value of grain protein content, hardness, Zeleny sediment, grain color, swelling index of glutenin(SIG), and flour swelling volume(FSV) were 14.78%、62.63%、44.39 ml、56.46、 (-1.90、) (16.67、) 5.86、13.44 ml/g, separately, The coefficient of variation of different wheat varieties (lines) were (5.71%、) 4.61%、12.70%、7.48%、12.44%、7.26%、14.77%、6.30% , repectively. There were significance correlation in these wheat quality index each other, and 6 category in 47 wheat varieties (lines). |
