Abstract
Neutralino dark matter is studied in the context of a supergravity sch eme where the soft scalar mass terms are not constrained by universali ty conditions at the grand unification scale. We analyse in detail the consequences of the relaxation of this universality assumption on the supersymmetric parameter space, on the neutralino relic abundance and on the event rate for the direct detection of relic neutralinos.
