  We study the light gluino scenario giving special attention to constraints
from the masses of the light CP-even neutral Higgs $m_h$, the lightest chargino
$m_{\chi^{\pm}_1}$, and the second lightest neutralino $m_{\chi^0_2}$, and from
the $b\rightarrow s\gamma$ decay. We find that minimal $N=1$ supergravity, with
a radiatively broken electroweak symmetry group and universality of scalar and
gaugino masses at the unification scale, is incompatible with the existence of
a light gluino.
