Principal component analysis (PCA) and phylogenetic analysis using Neighbour joining (NJ) based on SNP genotypic data. A: PCA on SNP genotypic data of the eight chickpea accessions. The X and Y-axes show PC1 (21.2%) and PC2 (20.3%), respectively. B: NJ tree showing genetic relationships among the chickpea accessions. The NJ-tree grouped chickpea genotypes into two major clades wild and cultivars. Further the cultivars were grouped into sub-clades, i.e., desi and kabuli types.
