Table 3 Quantitative genetic partitioning of variation and significance of effects across drought and control treatments, and Pearson correlation coefficients for across-treatment genotypic correlations (r _GE ) for each trait. Standard error is indicated in parenthesis. Estimates of r _GE for all traits are significantly different than 0, as indicated by a significant effect of Genotype; r _GE for above- and below-ground biomass, root:shoot ratio, and fruit production are significantly less than 1, as indicated by significant effects of genotype × treatment interactions
