We study the non-universal gaugino mass (NUGM) scenario in the Minimal Supersymmetric Standard Model. Suitable ratios of gauginos, superpartners of gauge bosons, enhances the SM-like Higgs boson mass and relaxes the degree of tuning to realize the electroweak scale above a few percent level at the same time. We investigate signals of superparticles in the NUGM ! scenario at the Large Hadron Collider (LHC) and observations for the dark matter. The LHC experiment probes superpartners of quarks and a gluon efficiently. We specify expected signals from these superparticles and extract limits from recent data. The dark matter observations survey the neutralino sector directly. The indirect detection constrain the dark matter mass itself, while the direct detection are sensitive to the gaugino masses and then directly probes the gaugino mass ratios.
