¹ ${\text{r}}_{{\text{pc}}_{\text{TROP}}}$ = purebred–crossbred genetic correlation in tropical environment; ${\text{r}}_{{\text{pc}}_{\text{TEMP}}}$ = purebred–crossbred genetic correlation in temperate environment; ${\text{r}}_{{\text{g}}_{\text{PB}}}$ = genotype by climate interaction in PB; ${\text{r}}_{{\text{pc}}_{\text{TROP}-\text{TEMP}}}$ = genetic correlation between the performance of PB in tropical climate and CB in temperate climate; ${\text{r}}_{{\text{pc}}_{\text{TEMP}-\text{TROP}}}$ = genetic correlation between the performance of PB in temperate climate and CB in tropical climate.

*Genetic variance components converged restrained (liable to change from positive definite to fixed at a boundary) and thus should be interpreted with caution; nc = not converged.
