Figure 5
Analyses of thirty-eight quantitative traits related to fruit shape and size. Description of phenotypes is available in Supplementary Table S3. (a) Coefficients of variation (CVs) show that very often the standard deviation exceeds the mean value of the trait, suggesting a great variability of the traits. (b) Spearman’s rank correlation coefficients between pairs of phenotypes. Only correlation coefficients with p-value < 10e-7 are shown. In (a) and (b) green dots mark phenotypes that are significantly different between clusters of C. annuum identified in the admixture analysis, while orange dots mark phenotypes showing significant association with genetic markers in genome-wide association tests. (c) Traits that significantly differs between the two subgroups of C. annuum identified from genetic clustering analysis. Cluster 1 contains bulkier and larger fruits compared to Cluster2.
