Which of the following statements is not correct plant breeding ?

Options

A. It reduce the dependence on fungicides and bactericides.
B. It provides somaclonal variation.
C. It is independent of germplasm collection.
D. It involves self-pollination of plants

Explanation

To determine which statement is not correct about plant breeding, we can follow these steps:

### Step-by-Step Solution:

1. **Understand Plant Breeding**:
- Plant breeding is the science of changing the traits of plants to produce desired characteristics. The main aim is to improve the quality of nutrition and produce crops with superior traits.

2. **Identify Commonly Targeted Traits**:
- The traits commonly targeted in plant breeding include tolerance to biotic (pests, diseases) and abiotic (weather conditions) stresses.

3. **Recognize the Steps in Plant Breeding**:
- The steps involved in plant breeding include:
- **Selection**: Choosing plants with desirable traits.
- **Propagation**: Propagating the selected plants.
- **Elimination of Undesirable Traits**: Removing less desirable characteristics from the plants.

4. **Evaluate the Statements**:
- Now we need to evaluate the provided statements to find the incorrect one:
- **Statement 1**: "It reduces the dependence on fungicides and bactericides." - This is true as improved crops can be more resistant to diseases.
- **Statement 2**: "It provides somaclonal variation." - This is also true as plant breeding can lead to variations.
- **Statement 3**: "It is independent of germplasm collection." - This is the incorrect statement because plant breeding relies on germplasm collection for genetic diversity.
- **Statement 4**: "It involves the self-pollination of the plants." - This is true as self-pollination can be a method used in plant breeding.

5. **Conclusion**:
- The statement that is not correct about plant breeding is: "It is independent of germplasm collection."

### Final Answer:
The incorrect statement about plant breeding is: "It is independent of germplasm collection."
