We study softly broken N=1 supersymmetric QCD with the gauge group SU(N c ) and N f flavours of quarks for N f >N c +1. We investigate the phase structure of its dual theory adding generic soft supersymmetry breking terms, i.e. soft scalar masses, trilinear coupling terms of scalar fields and gaugino masses. It is found that the trilinear coupling terms play an important role in determining the potential minima. Also we compare softly broken original and dual theories in the broken phase.
