  For nearly degenerate neutrinos, quantum corrections can modify the
tree-levelmasses via low energy supersymmetric threshold corrections comparable
to the solar oscillation mass scale. We numerically calculate corrections to
neutrino masses in minimal supergravity (mSugra) and Gauge Mediated
Supersymmetry Breaking (GMSB) scenarios and identify parameter spaces in the
high energy regime for which the solar neutrino mass splitting becomes too
large compared to the LMA solution. We show that such considerations can give
bounds on GMSB and mSugra models which can be useful. On the contrary, if we
start from degenerate mass eigenvalues at the tree level, these threshold
corrections being generation dependent, can also produce the required mass
splitting at solar scale for regions of parameter space.
