• A. Biotechnology
• B. Traditional breeding
• C. Chemical fertilizers
• D. Mutation breeding

Answer 1

Answer: (A), (B), (D)

The correct options are
A Biotechnology
B Traditional breeding
D Mutation breeding

Disease resistant crop varieties are created by:

1. Biotechnology: some procedures are tissue culture, protoplast fusion, etc.
2. Traditional breeding: cross-hybridisation of superior parents to produce superior progeny.
3. Mutation breeding: by inducing mutations artificially through use of chemicals or radiations such as gamma or x-rays.
