Population structure in the ORSC. a fastStructure analysis for 286 ORSC samples based on 113,739 SNPs where black arrow indicates optimal number of populations at K = 6 (see also Additional file 3: Figure S2A); admixed accessions sharing <75 % ancestry with any one subpopulation are highlighted by red rectangles above K = 6 panel; wild group numbers, W1-W6, correspond to order of divergence (as shown in Additional file 3: Figure S2A); accessions included in the Wild Rice Diversity Panel (Wild RDP, n = 95) indicated as red stars under K = 6 panel; traditional species designations, O. rufipogon (perennial), O. nivara (annual), and O. spontanea indicated by black, blue and pink stars, respectively, under K = 8 panel. b Geographical map showing distribution of samples from each subpopulation group where circle size corresponds to number of samples; fill color indicates subpopulation designation (K = 6); For admixed accessions, the first mentioned subpopulation represents the major proportion of ancestry; Chinese accessions lacking location detail indicated in closed rectangle; further detail provided in Additional file 1: Table S1A. c Simplified geographical map showing regional distribution of six subpopulation groups (K = 6); d Detailed view of geographical distribution of subpopulation groups (K = 8) highlighting relationship between W4 and W8
