Transgenic Crops: Revolutionizing Indian Agriculture

Introduction

Transgenic crops that contain foreign genes by use of recombinant DNA technology are known as genetically modified organisms (GMOs) that promise improved yields, pest resistance and improved nutrition.

Definition and Technology

• Transgenic crops are those that incorporate the genes of other species that are not related (e.g. Bt toxin of Bacillus thuringiensis bacteria into cotton). Contrary to the conventional breeding, such peculiarities as herb-resistance or drought resistance are permitted in this very biotech.
• These methods are gene gun and agrobacterium-mediated transformation. India has an interest in Bt cotton (approved 2002) and ongoing GM mustard (DMH-11, approved 2022 amid controversy).

International Adoption and Case studies

• Globally, more than 190 million hectares (ISAAA 2023) in the first place in the United States of America (corn, soy), and in the second place in Brazil and Argentina. Dominating crops: Bt corn (insect resistant), Roundup Ready soy (herbicide resistant), Golden Rice (enriched with Vitamin A).
• India planted 95%+ (11.6 million ha, 2024) GM cotton and GM cotton yields 30-50 and GM cotton cuts pesticide application by 50 percent cutback. None of the GM food crops available in the market yet test trials on brinjal, rice and chickpea.

Indian Agriculture Economic benefits

• Increment in Yield and Productivity: Bt cotton had increased the income of farmers by 15, 000/ha/year (pre- 2020 data). In self-sufficiency of edible oil (60 percent of it is imported in India), GM mustard yields 28 percent more oil that is needed.
• Pest and Climate Resilience: Saves bollworm ( 10,000 crore of savings since 2002). Drought-tolerant GM maize is under water stress, and results on the trials yield 20 per cent more, a solution to 40 per cent susceptibility in the rainfed agricultural land areas.
• Nutritional Security: There is the application of GM crops like the bio-enriched Golden Rice which is being applied to curb micronutrient deficiencies in half of the Indian children (NFHS-5).
• The GM tech enhances the economically the PM-KISAN and Doubling Farmers Income goals.

Indian Regulatory Environment

• Trial/release sanctioned by Genetic Engineering Appraisal Committee (under MoEFCC). Bio safety levels (BLS-1 to 4) ensure containment.
• Key Milestones:
  • 2002: Bt cotton moratorium lifted.
  • 2022: GM clearance of mustard commercial (first food crop).
  • In waiting: Bt brinjal (waiting since 2010 protests).
• The directives of the Supreme Court which gave more importance to science-based regulation removed moratorium on field tests (2015-2021).

Scandals and Problems

• Health and Environmental risks: Aggregate: Critics refer to allergenicity, gene flow to wild relatives and superweeds. According to Bt cotton studies, it has been shown that there is no long term health issue in human beings (ICAR), but it has been exhibiting signs of antibiotic resistance.
• Socio-Economic Issues: Monsanto developed GM seeds that were the monopoly, hence became dependent on farmers; Indian Cervavac type GM seeds has it.
• Biodiversity Impact: There is the risk that the pollinators would be affected in a non-target manner; proactive monitoring on 10 years or more after release would be compulsory.

Status and Recent Developments (2026)

• By Feb 2026 GM cotton is king; mustard cultivation in Haryana/Rajasthan pilot projects. New trials GM rice (flood resistant), potato (late blight resistant). Nano-biolytics are more accurate and reduce off-target mutations.
• In budget 2026, 1000 crore is being given on biotech farms. 50 plus research stations head IICAR.
