Genomic breeding values’ prediction including populational selfing rate in an open-pollinated Eucalyptus globulus breeding population

Abstract In forest tree breeding programs, open-pollinated families are frequently used to estimate genetic parameters and evaluate merit of individuals. However, the presence selfing events not documented in pedigree affects estimation these parameters. this study, 194 Eucalyptus globulus Labill. trees were compare precision estimated accuracies predicted values with conventional pedigree-based model (ABLUP) pedigree-genomic single-step (ssGBLUP). The available information for pairwise parent-offspring allows us an actual populational rate 5.4%. For all growth disease resistance traits evaluated, inclusion was effective reducing upward bias, between 7 30%, heritability estimates. predictive abilities ssGBLUP models always higher than those ABLUP models. both cases, a considerable reduction observed when relatedness training validation populations removed. We proposed straightforward approach population. incorporation parameter more reliable Furthermore, our results proved that accurate improve prediction events, thus valuable tool genomic evaluations programs.
