Pomato is the Potato and Tomato hybrid. This is a hybrid of an intergeneric kind. Pomato can be formed by somatic hybridization. The mechanism by which two separate species of plant protoplasts fuse together to form hybrids is known as somatic hybridization. Pomato is an example of allopolyploid. Cherry tomatoes, in this case, grow on the vine while white potatoes emerge from the same plant in the soil.
