Protoplasts are cells that have had their cell walls removed.  They can originate from plants, bacteria, or fungi.  The answer to your question is a hybrid.  Protoplasts can be used for genetic modification in plants.  The cell walls are removed using enzymes and the cells and their nuclei are fused together using either electrical stimulation or chemical means (like polyethylene glycol).  The nuclei fuse to create a new genetic hybrid cell.  This can be done to create new genetic strains of plants that have beneficial characteristics.  So the answer to your question is hybrid.
