Population Structure analysis, principal components and neighbour joining tree analysis representing 198 rice accessions. a Population structure (K=2); the areas of the two colors (red and green) depict the two subpopulations. b Plot of ∆K calculated for K =2. c Distribution of selected accessions along the three PCs. PC1 and PC2 refer to the first and second principal components respectively. Dots denote each accession of the rice subset. d Neighbour joining tree with different colours represent the subpopulations identified in our study i.e. red and blue represent the indica subspecies and other subpopulations, respectively
