Hello Supriya,

Congratulations on getting such a good rank.

Having said that, I would say you should check with yourself with what are you more interested in.

I would advise you to opt for MSc Plant biotechnology, because this wouldn't narrow down your field and you will surely have genetics and plant breeding in the course as a part of it.

Though if you choose MSc genetics and plant breeding, you'll surely miss some of the important topics in plant biotechnology. Also this would narrow down your field.

With narrow down your field i mean just in case you want to pursue your PhD in some of the topic relevant to Plant biotechnology, you might miss out on those just because you pursued MSC in genetics and plant breeding.

Otherwise both the courses have equal scope

Hope that helps you

All the best
