U.S. biotech company Monsanto Co hopes to gain regulatory approvals to commercialize some varieties of its biotech corn in India in about five years, a company official said on Thursday. ”There is a fundamental (amount of) time that is required for crops to be evaluated ... We can be in the four-year time frame, but my guess is we will be in the five-year time frame on this one,” Sekhar Natarajan, head of Monsanto’s Indian operations, said in an interview with Reuters.
