Explain how the Green Revolution helped India to be self-sufficient in food grain production.

Green Revolution was the name given to the technological breakthrough achieved in farm production in India after the late 1960s.
In the late 1960s, the Green Revolution introduced the Indian farmer to better r
cultivation methods using High Yielding Varieties (HYVs) of seeds. This led to a growth in the productivity of food grains (especially wheat and rice), thereby helping India attain self-sufficiency in food grains.
The production of wheat was just 88 lakh tonnes in 1955-56. Now, it has crossed 718 lakh tonnes. Since the advent of the Green Revolution, the country has avoided famine even during adverse weather conditions. The highest role of growth was achieved in Punjab and Uttar Pradesh.
