Abstract
Non-universal boundary conditions in grand unified theories can lead to non-universal gaugino masses at the unification scale. In R-parity preserving theories the lightest supersymmetric particle is a natural candidate for the dark matter. In this talk the composition of the lightest neutralino is studied, when nonuniversal gaugino masses come from representations of SO(10). In these cases, the thermal relic density compatible with WMAP observations is found.
