Answer

To determine how many of the statements are incorrect, we will analyze each statement one by one.

### Step-by-Step Solution:

1. **Statement (i)**: "Pusa Gaurav, a variety of Brassica, is disease resistant for bacteria."
- **Analysis**: This statement is incorrect. Pusa Gaurav is actually known for being resistant to insects, particularly aphids, not bacteria.

2. **Statement (ii)**: "Jaya and Ratna are varieties of wheat."
- **Analysis**: 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."
- **Analysis**: This statement is correct. Micropropagation is indeed the method used to produce thousands of plants from tissue culture.

4. **Statement (iv)**: "Pusa Sawani is a variety of Brassica."
- **Analysis**: This statement is incorrect. Pusa Sawani is not a variety of Brassica; it is actually a variety of Bhindi (Okra).

5. **Statement (v)**: "Capacity to generate a whole plant from any cell explants is called totipotency."
- **Analysis**: 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 ability to generate a whole plant.

### Summary of Findings:
- Incorrect Statements: (i), (ii), (iv)
- Correct Statements: (iii), (v)

### Conclusion:
There are **3 incorrect statements** out of the 5 provided.

### Final Answer:
**3**
