要旨本文	Teak is one of the important tropical timbers that is grown, traded worldwide. Climate challenges raise the necessity for teak plantation to find a new strategy to identify climate resilience individuals yet still maintain their growth performance. Genome Wide Association Study (GWAS) and Genomic selection (GS) are emerging approaches in tree breeding that improve its speed and efficiency. We assessed the genomic selection model on 617 individuals using 12,419 SNP markers. We developed the prediction model for growth, leaf, and wood property traits and compare GBLUP, Bayesian and kernel-based approach on 48, 96, 192, and all marker scenarios. Our result shows median of prediction accuracy from 10 iterations range -0.002(SPAD)-0.335(PYL) while maximum accuracy results range 0.12(H26)-0.421(PYL). Our results show that GS provides room for improvement of teak to enhance teak plantation resilience amidst the changing environment by incorporating both volumetric and adaptive traits.
