We study the implications of such non-universal gaugino masses for the composition of the lightest neutralino in supersymmetric (SUSY) theories based on SU(5) gauge group. We also consider the phenomenological implications of non-universal gaugino masses for the phenomenology of Higgs bosons in the context of Large Hadron Collider.4 pages, 8 eps figures, style files included, Talk at LCWS06, Bangalore, India; typos correctedHigh Energy Physics - Phenomenologytext
