Graphic representation of QTLs showing interaction effects for the number of pods per plant in Pusa Dwarf /HDM04-1 F2:3 population. Circles represent QTLs with only additive effect while squares represents QTLs with only dominant effect. Connecting lines indicate significant interactions between the main effect QTLs.
