Question

Tissue culture technique can produce the indefinite number of new plants from a small parental tissue. The economic importance of the technique is in raising

• A. Development of new species
• B. Variants through picking up somaclonal variations
• C. Genetically uniform population of an elite species
• D. Homozygous diploid plants

Answer 1

Answer: (C)

Genetically uniform population of an elite species

Tissue culture technology is based on the fact that whole plant can be regenerated from explants i.e., any part of a plant grown in a test tube, under sterile conditions in special nutrient media and growth regulators. This capacity to generate a whole plant from any cell/explant is called totipotency. Each of these plants will be genetically identical to the original plant. Many important food plants like tomato, banana, apple etc., can be produced on the commercial scale by this method.

Thus, the correct answer is option C.
