It is shown that the chiral model with SU(3) flavor symmetry predicts a dibaryon state of low mass M (Mroughly-equal2x2 GeV). It is electrically neutral and is an SU(3) singlet with J/sup P/ = 0/sup +/. It corresponds to a six-quark state found in the MIT bag model by Jaffe. It is also shown that there is no stable particlelike state of baryon number 2 which is based on Skyrme's spherically symmetric ansatz for the chiral field.
