Figure 5. Microsatellite and SNP marker-based estimation of genome-wide and population-specific LD patterns in wild chickpea.

(A) Estimates of LD (mean r²) for linked, unlinked and global markers (478 genic and genomic microsatellite markers and 380 TF gene-based SNP markers). The bar indicates the standard error. *ANOVA significance at p<0.01. (B) LD decay (mean r²) in six population groups as defined by population genetic structure. For LD decay, the r² value of marker physical distance of 0 kb is considered as 1. The marked dots indicate the mean r² values for marker intervals of 0–200, 200–400, 400–600, 600–800, 800–1000 and 1000–1200 kb, respectively. The curve was drawn across the dots using non-linear regression model. “All” includes the LD estimates and decay across entire six population groups.
