Note: Pred.: predictions for traits in the GWAS trials from the PLSR models built using the pooled training sets; V_cmax (μmol m⁻²s⁻¹): maximal Rubisco carboxylation; V_pmax (μmol m⁻²s⁻¹): maximal PEP carboxylation; J_max (μmol m⁻²s⁻¹): maximal electron transport rate; SLN (g m⁻²): specific leaf nitrogen content: LMA (g m⁻²): leaf mass per area; H²: generalised heritability.
