Fig. 2

Box plots showing the association of SNP genotypes with six fruit traits. The SNPs shown explained more than 10% of the phenotypic variance for the indicated trait(s). Box plots for different traits associated with the same SNP are enclosed by rounded rectangles. Chr15_1792340 for SUC and Chr15_16568005 for FRU, which are close to one another, are enclosed by a rounded rectangle with a dotted line. Chr04_29871378 for FRU and Chr12_4383743 for FruH were identified only in the vBayesB-based GWAS analysis (Table 4); the rest were identified in the MLM-based GWAS analysis (Table 3) or in both. The fictive chromosome 0 contains all unassigned scaffolds. For each QTL genotype, the red dot and thick horizontal line indicate the average value and median value, respectively
