The new $f_0(1790)$ meson recently observed by BES collaboration in
$J/\Psi$-decay, is seen only in the OZI-forbidden channel. It is shown that
chiral symmetry restoration in excited hadrons implies a new selection rule of
dynamical origin that forbids some of the OZI-favoured mechanisms of decays.
Hence decays into channels that are suppressed by OZI can become dominant.
