In supersymmetric quantum chromodynamics with Nc-colors and Nf-flavors
of quarks, our effective superpotential provides the alternative description to
the Seiberg's N=1 duality at least for Nf>=Nc+2, where
spontaneous breakdown of chiral symmetries leads to SU(Nc)L+R
xSU(Nf-Nc)L xSU(Nf-Nc)R
as a nonabelian chiral symmetry.The anomaly-matching is ensured by the presence
of Nambu-Goldstone superfields associated with this breaking and the instanton
contributions are properly equipped in the effective superpotential.
