Gene Campaign has sought a ban on the field trials of Bt rice that are taking place in parts of the country ”in violation of regulations and conditions laid down for field trials of genetically modified crops.” Saying that no country -- that is the centre of origin of any crop -- allows genetically modified(GM) version of that crop so as to protect the genetic wealth and diversity, Suman Sahai of the Campaign said that it was for that reason that Mexico banned GM corn, Peru disallowed GM potato, and China banned GM soyabean.
