We report the preliminary results of the studies of hadron spectrum under the background of abelian and monopole gauge fields in quenched Wilson SU(3) QCD. Abelian gauge fields alone reproduce the same chiral limit as in the full case. Critical hopping parameter $\kappa_c$ and $m_{\rho}$ are the same in both cases. We need more time to get a definite result in the case of monopole background. The photon contribution do not produce any mass gap in the chiral limit ($\kappa=\kappa_c\sim 0.17$). The behavior is similar to those in the free photon case for $\kappa_c= 0.125$.
