要旨本文	Rubroshorea macrophylla, commonly known as red meranti, holds significant commercial importance. To better understand the genetic mechanisms underlying key phenotypes, we conducted a genome-wide association study (GWAS) on diameter at breast height (DBH), total tree height (H), wood density (WD), and pilodyn penetration (PP).The study utilized spatial analyses to standardize heterogeneous data from 18.037 single nucleotide polymorphisms (SNPs). We collected 349 individual trees from half-sib progeny trial trees at PT-SBK in Central Kalimantan. We detected linkage disequilibrium (LD) decay up to 2427 base pairs, and genomics heritability values are 0.268, 0.273, 0.225, and 0.246 for DBH, H, PP, and WD, respectively.GWAS for DBH and H detected 3 SNPs, six and one SNPs for pilodyn penetration and wood density, based on LOD scores above three as thresholds.
