要旨本文	The half-sib hybrid larch cultivar “Clean-Larch” (Larix gmelinii var. japonica "Nakashibetsu-5" × L. kaempferi) is characterized by rapid juvenile growth and high carbon accumulation ability. Genomic prediction can be employed to accelerate the breeding process and improve growth and wood property traits. In this study, observed values, and adjusted values by spatial analysis for growth and wood property traits were used as phenotype data, respectively. Subsequently, genotype data (27,181 SNPs) combined with phenotype data were used to assess the prediction accuracies and biases of three single-trait and two multi-trait GP models incorporating additive and dominance effects. According to the prediction accuracies and biases, single-trait GP models incorporating additive plus dominance effects based on the adjusted values were more suitable.
