Genetic relatedness and population structure of the diversity panel; a Genetic diversity depicted through the unweighted neighbour-joining tree method within the population as indica (ind1A, ind1B, ind2, ind3 and indx) and aus accessions, as established in the 3k rice genome project; b Ancestory proportions from ADMIXTURE analysis represented for k = 3, the optimal with the lowest cross-validation error for K = 2–8 and visualized using R/pophelper package; c Cross-validation error for k = 2–8 from ADMIXTURE analysis; d Variation captured by the PCs using R/GAPIT corresponding to the 3 clustered distribution along the first three PC components
