An inbred corn line, designated BE1146BMR, is disclosed. The invention relates to the seeds of inbred corn line BE1146BMR, to the plants of inbred corn line BE1146BMR and to methods for producing a corn plant, either inbred or hybrid, by crossing the inbred line BE1146BMR with itself or another corn line. The invention further relates to methods for producing a corn plant containing in its genetic material one or more transgenes and to the transgenic plants produced by that method and to methods for producing other inbred corn lines derived from the inbred BE1146BMR.
