Abstract
We review the prospects for dark matter (DM) in two classes of supersymmetric (SUSY) models which are characterized by the different mechanism of SUSY breaking, namely the more common supergravity models with very large scale of SUSY breaking and the recent schemes where SUSY is broken at a relatively low scale and gravitinos are likely to be the lightest SUSY particle. We point out that the former scheme is in general associated with the cold dark matter (CDM) scenario, while the latter predicts a warm dark matter (WDM) dominated Universe.
