  In this paper we study Yukawa-unified SO(10) SUSY GUTs with two types of
SO(10) boundary conditions: (i) universal gaugino masses and (ii) non-universal
gaugino masses with effective "mirage" mediation. With these boundary
conditions, we perform a global chi^2 analysis to obtain the parameters
consistent with 11 low energy observables, including the top, bottom, and tau
masses. Both boundary conditions have universal scalar masses and "just so"
splitting for the up- and down-type Higgs masses. In these models, the third
family scalars are lighter than the first two families and the gauginos are
lighter than all the scalars. We therefore focus on the gluino phenomenology in
these models. In particular, we estimate the lowest allowed gluino mass in our
models coming from the most recent LHC data and compare these to limits
obtained using simplified models. We find that the lower bound on M_gluino in
Yukawa-unified SO(10) SUSY GUTs is generically ~1.2 TEV at the 1 sigma level
unless there is considerable degeneracy between the gluino and the LSP, in
which case the bounds are much weaker. Hence many of our benchmark points are
not ruled out by the present LHC data and are still viable models which can be
tested at LHC 14.
