GWAS analyses using the carioca diversity panel (CDP) genotyped by 1,516 high-quality SNPs and evaluated for lightness (L*) at harvest with threshold defined by the Bonferroni test (cutoff α = 0.05). a Manhattan plots showing the association between the SNPs and the traits, b QQ-plot for the model fit, c histogram of phenotypic data, and d boxplots illustrating the relationships between alleles and phenotype for the significant SNPs
