Answer

To determine how many statements are incorrect, we will evaluate each statement one by one.

1. **Statement (i)**: "Pusa Gaurav, a variety of Brassica, is disease resistant for bacteria."
- **Evaluation**: This statement is incorrect. Pusa Gaurav is indeed a variety of Brassica, but it is known for being resistant to aphids, not bacteria.

2. **Statement (ii)**: "Jaya and Ratna are varieties of wheat."
- **Evaluation**: This statement is also incorrect. Jaya and Ratna are actually varieties of rice, not wheat.

3. **Statement (iii)**: "Method of producing thousands of plants through tissue culture is called micropropagation."
- **Evaluation**: This statement is correct. Micropropagation is indeed the method used to produce a large number of plants from a small amount of plant tissue.

4. **Statement (iv)**: "Pusa Sawani is a variety of Brassica."
- **Evaluation**: This statement is incorrect. The correct name is Pusa Swarnima, not Pusa Sawani, and it is not a variety of Brassica.

5. **Statement (v)**: "Capacity to generate a whole plant from any cell explants is called totipotency."
- **Evaluation**: This statement is correct. Totipotency refers to the ability of a single cell to divide and produce all the differentiated cells in an organism, including the whole plant.

Now, let's summarize the evaluations:
- Incorrect statements: (i), (ii), (iv)
- Correct statements: (iii), (v)

**Total incorrect statements**: 3

### Final Answer:
There are **3 incorrect statements**.
