Matrix of plot-based heritabilities (h²_Plot, underlined diagonal values), genetic (cor_g) and phenotypic (cor_p) correlations (lower and upper triangle values, respectively) for grain yield (GY, Mg ha⁻¹), plant height (PH, cm), heading date (HD, days since 1 January), thousand grain weight (TGW, g), test weight (TW, kg hl⁻¹), grains per ear (GPE), and ear weight (EW, g) in the population of 358 European winter plus 15 spring wheat varieties (GABI-WHEAT population) phenotyped in up to eight environments
