Table 4 Pearson correlation coefficients and significance of bivariate genetic correlations among traits. Values above the diagonal indicate genetic correlations among traits in the drought treatment and values below the diagonal indicate genetic correlations among traits in the well-watered treatment. Symbols denote the significance of correlations after false discovery rate correction (P < 0.05) and correlations shaded in gray indicate those for which Z-tests found significant differences in correlation coefficients across treatments
