Population structure ofausrice.A The plot of ADMIXTURE subpopulation membership coefficients at K = 6. The cross-validation error values at different K indicates K = 6 as the most ideal sub-groups, B Biplot of first two PCA axes of 181 aus accessions colour coded according to the ADMIXTURE classification at K = 6, C Biplot of first two PCA axes of 181 aus accessions colour coded according to their geographical association. D NJ tree based on pairwise genetic distance. The accessions were colour coded according to the ADMIXTURE grouping (branch colour) as well as geographic origin as given in B and C
