Phenotypic correlations among all the traits. Heat maps illustrating the correlations measured in the RAC875/Kukri DH population grown under a Lameroo and b Roseworthy field-conditions and c drought and d well-watered treatments in the glasshouse. According to colour key, correlation coefficients between r ≤ -0.3 and 0.3 ≤ r are significant at p < 0.01 (**) and p < 0.05 (*)
