The Introduction of High-yielding varieties of seeds and the increased use of fertilizers and irrigation are known collectively as the Green Revolution, which provided the increase in production needed to make India self-sufficient in food grains, thus improving agriculture in India. Genetically modified high-yielding wheat was first introduced to India in 1963 by Dr. Norman Borlaug. Third Five-Year Plan (1961–1966) stressed on agriculture and improvement in the production of wheat. Past experience with the previous two Plans had convinced the policy makers that rate of agricultural growth was the main hampering factor on the path to development. The Plan document thus declared that, ‘Agricultural production has, therefore, to be increased to the largest extent feasible.’
