Hello, being a student of botany there are many options you can choose for Masters. I was also a student of botany. I have done my masters from botany right after completing my bachelor's. There are many disciplines in this field. One needs the generic skills in ecology, evolution, about plant molecular science. It gives students a broad base of knowledge about life science. You can choose the following subjects for Master -

Microbiology, Ecology, Environmental Science, Plant Pathology, Molecular Biology, Biotechnology, Genetics, Physiology etc.

Career options -

Wildlife biologists, microbiologists, Researcher, Work for Biodiversity conservation, Biotechnology companies etc

All the best
