Question

Which of the following is used to induce mutation in crop plants?

• A. Gamma rays
• B. Alpha rays
• C. X-rays
• D. Sunrays

Hint:

Gamma radiation can cause changes in the DNA of plants, leading to beneficial mutations for agriculture.

Answer 1

The Correct Option is A

Step 1: Understand mutation induction.
Gamma rays are high-energy electromagnetic radiation used in plant breeding to induce mutations for improving crops.
Step 2: Review the options.
- Gamma rays are the most common radiation used to induce mutations in crop plants.
- Alpha rays and X-rays are not typically used in mutation breeding.
- Sunrays do not have enough energy to induce mutations in plant DNA.
Step 3: Conclude.
Gamma rays are used to induce mutations in crop plants, making option (A) the correct answer.
Final Answer: \[ \boxed{\text{Gamma rays}} \]
