Epistatic interactions underlie phenotypic diversity of tree architecture in columnar apple

Phenotypic and genotypic data underlying Güvencli et al., Epistatic interactions underlie phenotypic diversity of tree architecture in columnar apple. Phenotype files per trait and year after outlier removal (standardised residuals |z| > 3 using a GBLUP model with population treated as fixed covariate). Trait abbreviations: in_len = INL, lsh_ang_1 = LSA, tr_brz_prop = TBZP, tr_coni = TC, tr_len = TL. Genotype matrix (GT_filtered_numeric_transposed.csv) is in numeric 0/1/2 format (31,825 SNPs × 509 genotypes) after filtering for marker/individual missingness > 0.1 and MAF < 0.05. Marker map (GM_v11.csv) with marker flanking sequences aligned to the GDDH13 v1.1 reference genome.
