  1. ***=p < 0.001; **=p < 0.01; *=p < 0.05; ns: not-significant; \( {H}_A^2 \) and\( {H}_P^2 \)denote different measures of heritability, as estimated from eqs. (1) and (2) of Foito et al. (2015) respectively. Variance components due to field replicate (\( {\sigma}_R^2 \)), plot (\( {\sigma}_P^2 \)), technical replication (\( {\sigma}_I^2 \)), analysis batch (\( {\sigma}_B^2 \)), sequence order (\( {\sigma}_S^2 \)) and offspring (\( {\sigma}_G^2 \)) are represented. v̅ is the mean variance of a difference of two genotype means. The significance of the offspring component, as tested by the change in deviance, is included. A double dagger (‡) shows metabolites for which a QTL was detected
