Table 1 Pairwise Pearson correlation coefficients among the four kernel color traits in the UMN_C4 intermediate wheatgrass population. Three traits (L*, a*, b*) were measured according to the CIELAB system and one was assessed visually (V). The symbol * next to the correlation coefficient values indicates significance at α = 0.05
