Identification of putative loci underlying selection using F ST and Spatial Ancestry Analysis (SPA). F ST analysis between elite and landrace population within each country: (a) America, (b) China, and (c) Japan. The F ST values are plotted against the base pair position on 20 chromosomes of soybean. The dashed horizontal line denotes the calculated F ST value based based on 99.9th percentile for declaring a selected region. The solid horizontal line denotes the calculated F ST value based on 99th percentile for declaring a selected region. Strong selection signals that co-localized with known genes or QTL are indicated by an arrow. (d) SPA of 3,012 geo-referenced landrace accessions in G. max. The SPA selection scores are plotted against the base pair position on 20 chromosomes of soybean. Strong selection signals that co-localized with known genes or QTL are indicated by an arrow. The dashed horizontal line denotes the calculated SPA threshold score based on 99.9th percentile for declaring a selected region. The solid horizontal line denotes the calculated SPA threshold score based on 99th percentile for declaring a selected region.
