Non-additive inheritance patterns for metabolites in hybrids. a Relative deviations of all measured metabolites from the mid-parent value. The indices correspond to the metabolite annotation provided in Table S1A and the metabolites are ordered according their relative deviations from negative to positive. b The number of primary metabolites inherited in non-additive way in different hybrids; c The number of secondary metabolites inherited in non-additive way in different hybrids. In b and c non-additive inheritance was based on significant deviation from the parental mean at level α = 0.01. The total number of analysed primary metabolites was 66 (numbered 1–66) and the total number of secondary metabolites was 33 (numbered 67–100). The four first groups (i.e. acids, amines, sugars, phosphates and polyol compounds) belong to primary metabolism and flavonoids, glucosinolates and phenylpropanoids to secondary metabolism
