Boxplot of bootstrap distribution for the slope of the regression of additive genetic values obtained with whole phenotypic information on additive values obtained with partial phenotypic information (\({{\varvec{b}}}_{w,p}\)) in leave-one-line out cross-validation. M1: spatial model 1 based on \({{\varvec{S}}}_{knn}\) correlation structure, M2: spatial model 2 based on \({{\varvec{S}}}_{euc}\) correlation structure, GY grain yield, GPC grain protein content, GNR grain nitrogen removal, TKW thousand kernel weight, TRL total root length, SRL shallow root length, DRL deep root length. The black dashed line represents a regression coefficient of one, where no under or over-dispersion is present
