Supersymmetric QCD with large matter representations is analyzed in the ladder approximation. In the nonrunning limit we find that chiral-symmetry breaking takes place when the coupling constant exceeds a critical value equal to 3/2 times the critical coupling of ordinary QCD. Fermionic condensation induces a nonzero scalar mass, which, in turn, stabilizes the broken-symmetry phase. The relevance of our results to supersymmetry breaking in realistic theories is discussed.
