Bar plots for the admixture indices for each individual in the Capsicum population for K= 2 a and K= 4 c clusters. b Inference for the best number of clusters using the Evanno method revealed the optimal number of clusters to be K= 2. d Linkage disequilibrium (LD) decay plot for the Capsicum population. The red dashed line represents the critical value for LD (r2= 0.20) and the blue solid line represents the non-linear regression curve. The intersection between the critical value and the regression curve is the point at which LD starts to decay (~5.59 Mb)
