N2 - The WZW action on SU(NC) × SU(NF) × U(1) group manifold was proposed as the bosonized theory of free colored and flavored Dirac fermions. Here difficulties are encountered in finding the fermion mass bilinears in terms of boson variables. We thus try an alternative approach using WZW theory on U(NC × NF) group manifold, where there is no problem with the mass bilinears. After gauging the color we obtain the bosonized form of multiflavor QCD2. The strong coupling limit is then taken and the low energy effective action is obtained. We then show that this action, though different from the one we got in the past from the "old" prescription, describes the same low lying semiclassical baryonic spectrum.
