Expert Answer:

Somatic cell hybridisation involves the fusion of somatic or body cells from two different varieties of a species or even from two different species.

Process of Somatic Cell Hybridisation

  • Cell walls of somatic cells are removed by the use of certain chemical and enzymes to form protoplasts.
  • The protoplasts are then fused either by chemicals or by a very brief high-voltage electric current to form a fused nucleus called heterokaryon.
  • The protoplasts are then cultured and treated chemically to regenerate cell walls.
  • They begin to divide and produce plantlets.
  • Examples of plants propagated through somatic cell hybridisation: Potato, tomato, wheat, rye.

Advantages and Disadvantages of Vegetative Propagation

ADVANTAGES

DISADVANTAGES

  • Faster and more certain method of propagation.
  • Does not produce new varieties.
  • New individuals produced have exactly identical qualities as their parents. This preserves the characteristics of food and flower crops.
  • Leads to overcrowding around the parent plant.
  • Can be used to reproduce plants that do not have viable seeds.
  • Very little possibility of dispersal.
  • The flowers produced are of a superior quality.
  • Certain desirable characteristics present in the fruit can be maintained.
