    A method for generating hybridly polarized vector beams by manipulating Pancharatnam-Berry (PB) phase is proposed. According to the law of optical axis varying with the spatial coordinates, a PB phase element is used to manipulate the PB phase and generate vector beams with local linear polarization. When the vector beam is incident to a quarter-wave plate, a hybridly polarized vector beam is obtained. By measuring the Stokes parameter, the polarization distribution of the output light field is reconstructed. The experimental results show that the output hybridly polarized field contains all polarization states on the longitude of Poincaré sphere perpendicular to S3 axis when input wave is linearly polarized light with polarization angle θ0=0. The output hybridly polarized field contains all polarization states on the longitude of Poincaré sphere perpendicular to S3 axis when input wave is linearly polarized light with polarization angle θ0=0. When the polarization angle θ0=π/2, the output hybridly polarized field includes all polarization states on the longitude of Poincaré sphere perpendicular to S1 axis.
