We derive the nonuniversal gaugino mass ratios in a supergravity (SUGRA) framework where the Higgs superfields belong to the nonsinglet representations 54 and 770 in an SO(10) grand unified theory (GUT). We evaluate the ratios for the phenomenologically viable intermediate breaking chain SU(4){sub C}xSU(2){sub L}xSU(2){sub R}(G{sub 422}). After a full calculation of the gaugino mass ratios, noting some errors in the earlier calculation for 54, we obtain, using the renormalization group equations, interesting low scale phenomenology of such breaking patterns. Here, we assume the breaking of the SO(10) GUT group to the intermediate gauge group and that to the standard model take place at the GUT scale itself. We also study the collider signatures in multilepton channels at the Large Hadron Collider (LHC) for some selected benchmark points allowed by the cold dark-matter relic density constraint provided by the WMAP data and compare these results with the minimal supergravity (mSUGRA) framework with similar gluino masses indicating their distinguishability in this regard.
