New regularities in mass spectra of hadrons

In the present note we analyse structure of bosonic and baryonic Regge-trajectories, using existing data on masses of hadrons with definite quantum numbers. It will be shown that an existing information on daughter Regge-trajectories agrees with a string picture of hadrons. It is pointed out that for baryonic trajectories there is a degeneracy of states with different parity and in a region of masses M > I GeV there is a possible supersymmetry between mesons and baryons. All these regularities are not present in existing quark models of hadrons and indicate to a high degree of symmetry of the large distance quark interaction
