Implementation of the realized genomic relationship matrix to open-pollinated white spruce family testing for disentangling additive from non-additive genetic effects

Popis výsledku v původním jazyce

The open-pollinated (OP) family testing combines the simplest known progeny evaluation and quantitative genetics analyses as candidates offspring are assumed to represent independent half-sib families. The accuracy of genetic parameter estimates is often questioned as the assumption of half-sibling in OP families may often be violated. We compared the pedigree- vs. marker-based genetic models by analysing 22-yr height and 30-yr wood density for 214 white spruce (Picea glauca (Moench Voss) OP families represented by 1694 individuals growing on one site in Quebec, Canada. Assuming half-sibling, the pedigree-based model was limited to estimating the additive genetic variances which, in turn, were grossly overestimated as they were confounded by very minor dominance and major additive-by-additive epistatic genetic variances. In contrast, the implemented genomic pairwise realized relationship models allowed the disentanglement of additive from all nonadditive factors through genetic variance decompositio
