MCOA analysis. A multiple co-inertia analysis (MCOA) of metabolites and enzymatic capacities both expressed in nmol g FW -1-min-1 for 106 genotypes. “a” represents the trajectory plots during fruit development for the first common component (CC1) and the third common component (CC3) plans. Numbers one to six correspond to values that were extrapolated from GLMM for all of the genotypes, at 40, 52, 64, 76, 88 and 100% of fruit development respectively. The grey numbers correspond to the 29 ‘low-fructose-to-glucose-ratio’ genotypes, and the black numbers correspond to the 77 ‘standard-fructose-to-glucose-ratio’ genotypes. Mean values of the fructose types at each point are linked by a line in red for the ‘low-fructose-to-glucose-ratio’ genotypes and in blue for the ‘standard-fructose-to-glucose-ratio’ genotypes. “b” represents the variable correlation plots that are associated with a, with metabolite variables in red and enzyme variables in blue.
