Following radiation is commonly used for inducing mutation in crops?

Options

A. UV rays
B. `gamma`-radiation
C. X-rays
D. `alpha`-rays

Answer

**Step-by-Step Solution:**

1. **Understand the Question**: The question asks for the type of radiation commonly used to induce mutations in crops.

2. **Identify the Types of Radiation**: The transcript mentions several types of radiation: UV rays, gamma rays, X-rays, and alpha rays.

3. **Evaluate Each Type of Radiation**:
- **UV Rays**: These are harmful and lethal to plants, hence not used for inducing mutations.
- **Gamma Rays**: These have a very short wavelength (1 x 10^-6 nm) and are effective in inducing mutations in crop plants, allowing for the development of desired traits.
- **X-Rays**: With a wavelength of 1 nanometer, they are primarily used for imaging and not specifically for inducing mutations.
- **Alpha Rays**: These have a larger wavelength (20 to 100 micrometers) and are not primarily used for inducing mutations but rather for electron transfer.

4. **Select the Correct Answer**: Based on the evaluation, gamma rays are identified as the most effective radiation for inducing mutations in crops.

5. **Conclude the Answer**: The correct answer to the question is gamma rays.

**Final Answer**: Gamma rays are commonly used for inducing mutations in crops.
