  The Higgs sector of the minimal nonlinear supersymmetric SU(5) model contains
three mass parameters. Although these mass parameters are essentially free at
the electroweak scale, they might have particular values if they evolve from a
particular constraints at the GUT scale through the RG equations. By assuming a
number of simple constraints on these mass parameters at the GUT scale, we
obtain their values at the electroweak scale through the RG equations in order
to investigate the phenomenological implications. Some of them are found to be
consistent with the present experimental data.
