In this talk we demonstrate a statistical analysis of the trait DBH (diameter at breast height) obtained from five Radiata Pine Breeding Company (RPBC) clonal trials. A one-stage approach in used in which individual tree records are analysed and both marker and pedigree information are incorporated. Additionally, the various sources of genotype by environment interaction, both additive and non-additive, are appropriately modelled. We discuss how the methodology may be used to provide information not only for genomic selection but also superior estimates of breeding values for routine forward selections.
