Heat map of the correlation matrix among traits based on mean values of each RIL within individual environment. Matrix was ordered by hierarchical clustering. Correlation between environments was not significant unless indicated by * (which means it is significant at P < 0.05 level). SW, Seed weight; ShW, shoot weight; P, NIR protein content of seeds; BT, biotron; ID, Idaho; 2018_19, samples from 2018BT and 2019BT combined.
