Matrix plot for the best linear unbiased estimations for HD (d), PH (cm) and TGW (g) as observed for 1,065 spring (in red) and 3,469 winter wheat accessions (in blue). Violin plots on the diagonal displays the dispersion of each trait of spring and winter wheat. Scatter plots in the upper and lower quadrant of the matrix shows the correlations among the three traits for spring and winter wheat, respectively. The Pearson’s correlation coefficients (r) which differ significantly from zero (P-value < 0.001) is indicated by ***.
