  First experimental data on the inclusive yields of Delta^{0}(1232) and
Delta^{+}(1232) isobars in neutrino-induced reactions are obtained. Their total
yields in neutrino-nucleon interactions, 0.145+-0.055 and 0.182+-0.054,
respectively, exceed the value of 0.091+-0.015 obtained recently for the
Delta^{++}(1232) state. The data for the all three states of Delta(1232) cannot
be reproduced by the LEPTO6.5 model. The fractions of \pi^0, \pi^- and \pi^+
mesons originating from the decay of lightest baryonic and mesonic resonances
are estimated to be, respectively 56.6+-9.6%, 39.5+-6.6% and 27.7+-3.2%.
