  We present the results of the contributions to the decay rate of the lightest
Higgs particle into a charm-anticharm and bottom-antibottom pair within the
minimal supersymmetric standard model when scalar quarks and a gluino are taken
within the relevant loop diagrams. We show that in the case where the vacuum
expectation values of the Higgs particles obey the condition $v_1\ll v_2$\ the
scalar quarks and gluino change the decay rate by not more than a few per cent.
These small contributions make it difficult to distinguish the Higgs particle
of the standard model from the supersymmetric one.
