Figure 3. Boxplot distributions analysis of fruit color phenotype (R/B)
by genotypes of significant GWAS SNPs from this study. Samples were
classified into three group: (a ) all 188 samples group,
(b ) wild type VIR group: samples with
VIR+/VIR+ or
VIR+/VIRsaf (n=25) and (c )
VIRIM group: samples with
VIRIM/VIRIM genotype (n=61) and then
further separated by genotypes of significant SNPs identified in this
study. P-values were calculated using by Wilcoxon statistical test. The
X-axis represents the SNP’s genotypes, and Y-axis represents R/B
phenotypic value. Results show significant association with fruit color
even when samples are separated by the VIR genotypes associated with
red/yellow fresh fruit color.
