Answer

To solve the question of selecting the incorrect statement, we will analyze each statement one by one.

### Step-by-Step Solution:

1. **Statement Analysis**:
- **Statement A**: "Bird flu which is normally seen as a common disease of domesticated fowls is a viral disease."
- **Evaluation**: This statement is true. Bird flu is indeed caused by a virus, specifically the H5N1 virus, and it primarily affects birds but can also infect humans.

2. **Statement B**: "Outcrossing is the practice of animal mating within the same breed with no common ancestors on either side of their pedigree up to 4 to 6 generations."
- **Evaluation**: This statement is also true. Outcrossing refers to breeding animals from the same breed that do not share common ancestors for several generations, which helps in increasing genetic diversity.

3. **Statement C**: "Rohu and common carp are some common freshwater fishes used for consumption."
- **Evaluation**: This statement is true as well. Both Rohu and common carp are widely consumed freshwater fish and are important in aquaculture.

4. **Statement D**: "Pusa komal is a crop variety of chilli which is resistant to bacterial blight."
- **Evaluation**: This statement is incorrect. Pusa Komal is not a variety of chilli; it is actually a variety of cowpea. Therefore, this statement is false.

### Conclusion:
The incorrect statement is **D**: "Pusa komal is a crop variety of chilli which is resistant to bacterial blight."

### Final Answer:
**D** is the incorrect statement.
