Population structure and ETN variation of 490 rice accessions. (a) Phylogenetic tree constructed using LD-pruned SNPs. (b) PCA plots for the first two components of 490 rice accessions. (c) Population structure determined by ADMIXTURE. Ancestral population number (K) ranged from two to six. (d) ETN variation of two subpopulations in two locations. Boxplot described ETN distribution of one subpopulation in one location, and each dot around the boxplot represent ETN value of one accession. ETN, effective tiller number; JX, Jiangxi province; HN, Hainan province. Different letters denote significant differences (P < 0.05) based on Duncan’s multiple-range test
