Q9 of 77 Page 65

Why are plants obtained by protoplast culture called somatic hybrids?

Plants obtained by protoplast culture are called somatic hybrids because these plants are formed by the fusion of protoplasts of two different plant varieties, each having desirable characters.

Also the new plant formed is not by the fusion of germ cells but protoplasts, hence the name somatic.
