A turbine rotor is provided. The turbine rotor has a plurality of blades assembled into blade rows and arranged on a turbine disk. Each blade has a blade root arranged in a blade retaining slot of the turbine disk extending in an axial direction. A locking plate is arranged between the respective blade root and a base of the blade retaining slot, for securing blades against a displacement along the blade retaining slot. The locking plate is fixed to the turbine disk by folds. The locking plate comprises a plurality of cooling air holes for the passage of cooling medium from a cooling air feed passage. The respective blade root comprises two grooves extending substantially azimuthally in relation to a turbine axis, and the respective locking plate comprises two tongues which are arranged such that they are connected to the two grooves of the blade root for sealing.
