Question

A technique of micropropagation is

• A. Embryo rescue
  
• B. Somatic embryogenesis
  
• C. Protoplast fusion
  
• D. Somatic hybridization
  

Answer 1

The correct option is B Somatic embryogenesis


Definition of micropropagation
Micropropagation is an $invitro$ technique that uses tissue culture for the commercial production of plantlets. The plantlets produced are genetically identical to the parent plant and are called somaclones.

Protoplast fusion
Fusion of the protoplast derived from somatic cells of plants belonging to different species to produce a hybrid protoplast is called protoplast fusion.

Embryo rescue
Embryo rescue involves the assistance in development of immature plant embryos that may not survive to become viable plants.

Somatic hybridisation
Somatic hybridisation is a process of developing hybrid plants by the fusion of protoplasts of two plant cells belonging to different species which generates a hybrid protoplast with desired characteristics.

Somatic embryogenesis
Somatic embryogenesis is an $invitro$ process by which a somatic cell is used to form an embryo. Somatic embryos are formed from plant cells that do not naturally form embryos. Using appropriate plant growth regulators in the culture media, somatic cells are induced to form embryos. Somatic embryogenesis is an alternative method of $invitro$ micropropagation.
