In minimal supergravity theories the soft supersymmetry breaking (SSB) parameters are universal near the Planck scale. Nevertheless, one often assumes universality at the grand-unification scale [ital M][sub [ital G]][approx]10[sup 16] GeV, and corrections to the SSB parameters arising from their evolution between the Planck and grand-unification scales are neglected. We study these corrections in minimal SU(5) and show that large splittings between the scalar mass parameters can be induced at [ital M][sub [ital G]]. These effects are model dependent and lead to significant uncertainties in the predictions of supersymmetric models.
