Population structure of the 145 rice accessions. a Delta K values plotted as the number of subpopulations. b Subpopulations (K = 2) inferred using STRUCTURE. c NJ tree based on Nei’s genetic distances. Yellow and green represent Pop1 and Pop2, respectively. d Principal component analysis of rice panel. Values in parentheses indicate the percentage of variance in the data explained by each principal component. e Pairwise relative kinship analysis by distance matrix of rice panel. f Genome-wide average LD decay estimated from 145/full (black), 56 Pop1/indica (yellow) and 89 Pop2 / japonica (green) landraces
