Pleiotropy is considered to have a significant impact on multi-trait evolution, but its roles in the evolution of domestication-related traits crop species been unclear. In soybean, several known quantitative trait loci (QTL) controlling maturity, called maturity loci, are major effects both flowering and highly correlated pleiotropic manner. Aiming at identification non-pleiotropic QTLs that independently control dissecting pleiotropy these important agronomic traits, we conducted QTL mapping experiment by creating population from cross between domesticated soybean G. max wild ancestor soja underwent stringent selection for non-pleiotropy maturity. Our analyses using experimental revealed novel acted manner: R1-1 controlled primarily R8-1 R8-2 while overlapped with QTL, affecting other traits. results suggest can be genetically separated, artificial during domestication diversification may favored such as E The identified this study will help identify valuable genes optimize soybean’s life history improve yield potential under diverse environments cultivation schemes.
