  The large forward-backward asymmetry of the top quark pair production
measured by the hadron colliders shed light on new physics signals beyond the
Standard Model. In the Randall-Sundrum model with an additional SU(3) group in
the strong sector, we compare the total cross section and forward-backward
asymmetry of the top quark pair production with the newest data obtained by the
CDF and the D0 collaborations. Our numerical analysis shows that the parameter
$c_q \gtrsim 0.5$, $c_t \sim -0.6\sim-0.8$, $\tan\phi \gtrsim 20$ or $\tan\phi
\leq 1/20$ and the first excitation of axial gluon with a mass about $5
\thicksim 6 \mathrm{TeV}$ can accommodate this large anomaly without violating
other experimental constraints.
