I wouldn’t be worried about being in a specifically biotechnology degree program. Grad programs will be looking for a skill set and research experience. You could major in biochem, biology, bioengineering, (you might consider botany if you’re into plant genetics) and be well-prepared for biotech in grad school. The utility of the business portion I think depends on what you want to do: start your own business? Work for a biotech startup? Work in research for a company like Monsanto?
