Population structure of 469 indica samples. a Mean LnP(D) values plotted as the number of subpopulations; b ΔK values plotted as the number of subpopulations; c Subpopulations (K = 2 and K = 4) inferred using STRUCTURE; d NJ tree based on Nei’s genetic distances. Blue, red, green, purple and black represent POP1, POP2, POP3, POP4 and Mixed, respectively; e Principal component analysis
