Population structure of 179 rice cultivars based 36 genome wide unlinked SNP markers. (a) Two sub-populations corresponding to ‘Aromatic-Japonica’ (red) and ‘Indica’ (green) cultivar groups. Admixture types in the two sub-populations (with part red and green shades) were ‘Aus’ cultivars that formed a separate group at K = 4, (b) Delta K vs K Evanno plot showing peak delta at K = 2.
