A new quark potential model, the quark delocalization and color screening model, is used for a systematic search of dibaryon candidates in the {ital u},{ital d}, and {ital s} three flavor world. The color screening results from unquenched lattice gauge calculations and quark delocalization similar to electron delocalization in molecular physics are included. Flavor symmetry breaking and channel coupling effects are studied. The model is constrained not only by the baryon ground state property but also by the N--N scattering phase shifts. The deuteron and the zero energy di-nucleon resonance are reproduced qualitatively. The model predicts that there might be two kinds of dibaryon states. Possible high spin dibaryon resonances are emphasized. {copyright} {ital 1995} {ital American} {ital Institute} {ital of} {ital Physics}.
