We report a detailed study of polarization characteristics and subpulse drifting in PSR J1110-5637 with the observations of the Parkes 64 m radio telescope at 1369 MHz. The observations revealed that the trailing component of the pulse profile has obvious subpulse drifting, while the leading component has no subpulse drifting. Using the two-dimensional fluctuation spectrum (2DFS), we detected three distinct emission modes in the trailing component (modes A, B and C). The emission in mode A is chaotic and indistinguishable, while modes B and C have obvious subpulse drifting. The vertical modulation periods P₃ of modes B and C are around the mean values of 12 P and 8 P, respectively. The subpulse drifting of PSR J1110-5637 will expand the pulsar sample with multiple subpulse drifting rates, and this will help future systematic studies on the physical origin of the subpulse drifting phenomenon.
