Abstract: Gauge mediation of supersymmetry breakdown has many attractive features andcan be realized in phenomenologically interesting string-motivated models. Wepoint out that in models with the Polonyi-like field stabilized at a lowexpectation value by quantum corrections, gravity seems to limit from above theadmixture of gravity mediation to the dominant gauge mediation channel.However, we also point out that in a class of such models the low energymetastable supersymmetry breaking vaccum appears to be cosmologicallydisfavoured. These features should hold also in the case of typical stabilizedmodels with anomalous U1 groups.
