Hi krithika,

The future of Biotechnology in India isn't so bright. 

India's main obstruction for the advancement Biotech is, well, India itself. Biotech is a unique field. It combines the concepts of engineering with Biology. India's administration is yet to grasp the workings of this field, yet alone compete globally in the same. For them Biotech is just like any other engineering field, with a peppering of Biology jargon.

So, yes if you are looking to pursue Biotech, I personally feel you should do your education from outside India as of now. Bachelor's, you can do here if there is some financial strain but ultimately Biotech is more fun if done outside India. That is the ground reality.
