Hadron spectroscopy based on relativistic Schr\"odinger-like wave   equations
  Relativistic potential-type equations are proposed which approximately reproduce important features and constraints of field-theoretic models and can be useful tool in hadron spectroscopy. Within this approach, the Regge-trajectory parameters and some properties of hihger radial excitations in the light quark sector are discussed.
