  In unified $\mathcal{N}=1$ supergravity scenario the gaugino masses can be
non-universal. The patterns of these non-universalities are dictated by the
vacuum expectation values of non-singlet chiral super-fields in visible sector.
Here, we have analysed the model independent correlations among the gaugino
masses with an aim to explain the $[1\div 3]\sigma$ excess of muon (g-2)
($\Delta a_\mu$). We have also encapsulated the interconnections among other
low and high scale parameters, compatible with the collider constraints, Higgs
mass, relic density and flavour data. We have noted that the existing
non-universal models are not capable enough to explain $\Delta a_\mu$ at
$[1\div 2]\sigma$ level. In the process, we have also shown the impact of
recent limits from the searches for disappearing track and long lived charged
particles at the LHC. These are the most stringent limits so far ruling out a
large parameter space allowed by other constraints. We have also performed
model guided analysis where gaugino masses are linear combination of
contributions coming from singlet and non-singlet chiral super-fields. Here, a
new mixing parameter has been introduced. Following the earlier methodology, we
have been able to constrain this mixing parameter and pin down the promising
models on this notion.
