In mung bean , resistance to yellow mosaic virus and powdery mildew were induced by

Options

A. Biofortification
B. Hybrid breeding
C. Mutation breeding
D. Conventional breeding

Answer

To solve the question regarding the resistance of mung bean to yellow mosaic virus and powdery mildew, we need to analyze the options given and determine which method was responsible for inducing this resistance.

### Step-by-Step Solution:

1. **Understand the Question**: The question asks about the method that induced resistance to yellow mosaic virus and powdery mildew in mung beans.

2. **Evaluate the Options**:
- **A. Biofortification**: This method typically involves enhancing the nutritional quality of food crops, not specifically for disease resistance.
- **B. Hybrid Breeding**: This involves crossing two different varieties to produce hybrids. While it can improve certain traits, it is not primarily used for inducing resistance to specific diseases like yellow mosaic virus or powdery mildew.
- **C. Mutation Breeding**: This method involves inducing mutations in plants to create new traits, including disease resistance. It is a well-known technique for developing resistant varieties.
- **D. Conventional Breeding**: This refers to traditional breeding methods that select for desirable traits over generations but does not specifically induce mutations.

3. **Identify the Correct Method**:
- The question specifies that the resistance was induced. Among the options, mutation breeding (Option C) is known for creating new traits, including disease resistance, through induced mutations.

4. **Conclusion**: After evaluating all options, the correct answer is **C. Mutation Breeding**. This method successfully induced resistance to the yellow mosaic virus and powdery mildew in mung beans.

### Final Answer:
**C. Mutation Breeding**
