DMPQ: Explain the Crop breeding and the introduction of GM crops for food production.

Conventional breeding, especially of crops, livestock and fish, focuses principally on increased productivity, increased resistance to diseases and pests, and enhanced quality with respect to nutrition and food processing. Advances in cellular genetics and cell biology methods in the 1960s contributed to the so-called ‘green revolution’ that significantly increased varieties of staple food crops containing … Read more

Green Revolution and its impact on major crops of India

  The Green Revolution was initiated in the 1960’s to address the issue of malnutrition in the developing world. The technology of the Green Revolution involved bio-engineered seeds that worked in conjunction with chemical fertilizers and heavy irrigation to increase crop yields. Green Revolution was largely confined in wheat crop and in northern India such … Read more
