Green revolution in India occurred during;
1 1950 's
2 1960 's
3 1970 's
4 1980 's
Explanation:
Green revolution was the notable increase in cereal-grains production in Mexico, India, Pakistan, Philippines and other developing countries in the 1960's. This resulted in introduction of hybrid strains of wheat, rice and corn and the adoption of modern agricultural technologies.

Assertion : Wild varieties of crop plants must be conserved. Reason : Genome of wild plants serve as important resource for selection of desired genes like genes for pest resistance.
1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
3 Assertion is correct but Reason is incorrect.
4 Both Assertion and Reason are incorrect
Explanation:
Plant breeding involves selection of parents with desired characters, their crossing and selection of hybrid progeny with desired character. Wild varieties of crop plants have better resistance to insects, pests, diseases, etc. During plant breeding these wild varieties serve as germplasm resource where genes for disease resistance, etc., can be searched and selected. The wild varieties with desired character can be crossed with crop plants to obtain desired set of characters in the progeny. Therefore, wild varieties of crop plants must be conserved, otherwise large amount of germplasm will be lost.
