The linkage disequilibrium (LD), principal component and kinship analyses of soybean genetic data. a The estimated average linkage disequilibrium (LD) decay of soybean genome. The dashed line in blue indicated the position where r2 was 0.5. b The first three principal components of 34,710 SNPs used in the GWAS indicated little population structure among 278 tested accessions. c The population structure of the soybean germplasm collection reflected by principal components. d The heat map of the kinship matrix of the 278 soybean accessions calculated from the same 34,710 SNPs used in the GWAS, suggesting low levels of relatedness among 278 individuals
