Hello aspirant,

Hope you are doing absolutely great.

So with regard to your query, generally PhD should be done only after completion of MSc course only. However, some of the colleges provide integrated PhD in Botany, these are as follows:

1. Jiwaji University, GWalior

2. Punjab University

3. Ram Narain University

4. University of Delhi

5. Maharshi Dayanand Saraswathi University

Hope this helps you!!
