Abstract:

Principal component analysis on 13 wheat quality traits of F1 produced from 9 winter wheat varieties by Incomplete diallel cross design was carried out for appraising the contribution of wheat quality index to the qualities of different wheat. The results showed that 5 principal component factors, their cumulating contribution ratio reached to 85.52%, which could be obtained from 13 quality traits according to principal component analysis. Cumulating contribution ratio of first principal component factors to the wheat quality was the highest, which was 39.29%, followed by the second principal component factors. Appropriate increasing the first, second and fourth principal component factor will be favorable for improving the qualities of strong-gluten winter wheat and appropriate increasing the third principal component factor will be favorable for improving the qualities of weak-gluten winter wheat in winter wheat quality breeding.
