The seed weight of soybean [Glycine max (L.) Merr.] is one the major traits that determine yield and closely related to size. However, genetic basis synergistic regulation unclear.To understand molecular for formation traits, present study focused on QTLs mapping size in different environments target genes mining.A total 85 associated with were identified using a recombinant inbred line (RIL) population developed from Guizao1×B13 (GB13). We also detected 18 environmentally stable QTLs. Of these, qSL-3-1 was novel QTL main effect length. It all environments, three which explained more than 10% phenotypic variance (PV), maximum 15.91%. In addition, qSW-20-3 width, four environments. And amount (PVE) varied 9.22 21.93%. Five clusters both summarized by cluster identification. Fifteen candidate may be involved regulating screened based gene function annotation GO enrichment analysis.The results provide biologically basic reference understanding traits.
