Taking into account the color-electrostatic and magnetic energies due to one gluon exchange(OGE) interaction, along with that due to the residual quark-pion coupling arising out of the requirement of the chiral symmetry and due to necessary centre-of?mass(c.m) motion and the interactions between the constituent quarks arising out of Goldstone-Boson exchange(GBE), which are considered to play an important contributing to the energy of the Baryon core, were not taken into account in our earlier works, the baryon resonance spectra are calculated in a chiral symmetric ?Potential Model of independent quarks?. The effective potential representing Phenomenologically the non-perturbative gluon interactions including gluon self-couplings, is chosen with equally mixed scalar and vector parts in a linear form. The calculated values of baryon resonance spectra are found to agree reasonably well with the experiment .It is found that OGE corrections require a value of quark gluon coupling constant α_c=0.50 which is consistent with the idea of treating OGE effects in low order perturbation.
