The "Green revolution" was introduced during which of the following period in India?

1960s

The Green Revolution that came in the late 1960s introduced the Indian farmer to cultivation of wheat and rice using high yielding varieties (HYVs) of seeds. Compared to the traditional seeds, the HYV seeds promised to produce much greater amounts of grain on a single plant. As a result, the same piece of land would now produce far larger quantities of foodgrains than was possible earlier. The father of "Green revolution" in India is M.S. Swaminathan.
