We analyze the effects of soft supersymmetry-breaking terms on {ital N}=1 supersymmetric QCD with {ital N}{sub {ital f}} flavors and color gauge group SU({ital N}{sub {ital c}}). The mass squared of some squarks may be negative, as long as vacuum stability is ensured by a simple mass inequality. For {ital N}{sub {ital f}}{lt}{ital N}{sub {ital c}}, we include the dynamics of the nonperturbative superpotential and use the original (s)quark and gauge fields while, for {ital N}{sub {ital f}}{gt}{ital N}{sub {ital c}}+1, we formulate the dynamics in terms of dual (s)quarks and a dual gauge group SU({ital N}{sub {ital f}}{minus}{ital N}{sub {ital c}}). The presence of negative squark mass-squared terms leads to spontaneous breakdown of flavor and color symmetry. We determine this breaking pattern, derive the spectrum, and argue that the masses vary smoothly as one crosses from the Higgs phase into the confining phase. {copyright} {ital 1996 The American Physical Society.}
