The hadroproduction of charmed mesons is discussed within the framework of the modified Quark-Gluon String model (QGSM) taking into account the decays of corresponding S--wave resonances like D^*. It is shown that the estimate of the cc--pair contribution to the quark sea of colliding hadrons strongly depends on the parametrization of the function of the leading light quark fragmentation into charmed mesons. A description of the existing experimental data on inclusive spectra and asymmetries of leading and nonleading D - and D^* - meson production in πp -, p p - and Σp - collisions is obtained. The predictions for leading/nonleading asymmetry in Σ- p-- and Ξ-p-- collisions are also given.
