  When the GUT relation on gaugino masses is relaxed, the mass and composition
of the lightest neutralino are different from those in the GUT case. We discuss
its phenomenological implications on the relic abundance of the neutralinos and
on superparticle searches. In particular, we focus on the case where the
neutral component of Winos dominates the lightest neutralino. It turns out the
Wino-LSP is not a candidate for the dark matter.
