An inbred pumpkin line, designated ZYPMB24, is disclosed. The invention relates to the seeds of inbred pumpkin line ZYPMB24, to the plants and plant parts of inbred pumpkin line ZYPMB24 and to methods for producing a pumpkin plant, either inbred or hybrid, by crossing the inbred line ZYPMB24 with itself or another pumpkin line. The invention further relates to methods for producing a pumpkin 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 pumpkin lines derived from the inbred ZYPMB24.
