The SU(3) symmetry of baryon Regge poles is explored by comparing the angular distributions of backward meson-baryon reactions whose Regge exchanges should be SU(3)-related. Several indications of the symmetry are found. In particular, it is discovered that one can generate the observed highly structured angular distribution for π+p→pπ+ from the featureless one for K+p→pK+ simply by assuming SU(3) symmetry and taking singlet-octet exchange degeneracy in K+p scattering into account. Using the symmetry, evidence that exchange degeneracy between the Reggeized 1/2+ and 32- octets is broken is found. Relevant experiments are suggested.
