Question

Which of the following types of mutation is mainly used for crop improvement?

• A. Chemical mutation
• B. Induced mutation
• C. Hybridization
• D. Both A and B

Answer 1

Answer: (D)

Both A and B

Different types of breeding mechanism are used for the improvement of crop and obtain the crops which have better yield and quality. Mutational breeding is a type of breeding which is used to produce the crops with superior qualities. The selected parent plant is exposed to chemicals and mutagenic agents which can induce mutation. These agents mutate the gene and result in the activation of certain genes which are responsible for better qualities. Hybridization is a technique of crop breeding which used for crop improvement where the two parent plant combines together having the desired trait. It is not a type of mutation.

Thus, the correct answer is option D.
