  We investigate squark and gluino pair production at LHC (CMS) with subsequent
decays into quarks and LSP for the case of nonuniversal gaugino masses.
Visibility of signal by an excess over SM background in (n > 1)jets +
E^{miss}_T events depends rather strongly on the relation between LSP, gluino
and squark masses and it decreases with the increase of LSP mass. For
relatively heavy LSP mass closed to squark or gluino masses and for
(m_{\tilde{q}}, m_{\tilde{g}}) > 1.5 TeV signal is too small to be observable.
For the case when only third generation squarks and LSP are relatively light
signal is not visible without b-tagging.
