Plots of divergence index (Fst), nucleotide diversity (θπ) and fixed SNPs within the QTL regions. (a) QTL region of root fresh weight on chromosome 8. (b) QTL region of total plant fresh weight and total nodule fresh weight on chromosome 18. Gray boxes highlighted regions with high nucleotide diversity and large number of fixed nucleotides. (c) QTL region of total nodule fresh weight on chromosome 12. (d) QTL region of ureides content on chromosome 17. Gray box highlighted region with above-average Fst values, high nucleotide diversity and large number of fixed nucleotides. Black dots: Fst values between wild and cultivated soybeans. Purple line: average Fst value of the chromosome. Red dots and blue dots indicate the θπ of cultivated soybeans and wild soybeans, respectively. Red lines and blue lines indicate the number of fixed SNPs of cultivated soybeans and wild soybeans, respectively. Black lines: average number of fixed SNPs in a chromosome of cultivated soybeans.
