A phenomenological study of Bloom‐Gilman duality is performed in electron and neutrino scattering on nuclei. In the resonance region the structure functions are calculated within the phenomenological models of Ghent and Giessen groups, where only the resonance contribution is taken into account, and the background one is neglected. Structure functions F2 in the resonance region are compared with the DIS ones, extracted directly from the experimental data. The results show, that within the models considered the Bloom‐Gilman duality does not work well for nuclei: the integrated strength in the resonance region is considerably lower than in the DIS one.
