Transgenic Mustard DMH-11 in India Aims to Reduce Oil Imports

Transgenic Mustard (DMH-11) in India

Transgenic Mustard DMH-11

India is one of the world’s largest consumers of edible oil, yet it imports more than 60% of its total demand, making it highly dependent on global markets. Mustard (rapeseed) is the country’s second-most important oilseed crop after soybean, and improving its yield is seen as a strategic step toward reducing import dependency.

The University of Delhi’s Centre for Genetic Manipulation of Crop Plants (CGMCP), led by Dr. Deepak Pental, spearheaded the development of Dhara Mustard Hybrid-11 (DMH-11), a transgenic hybrid mustard variety.

The Innovation

  • Technology Used:

    • DMH-11 was created using the barnase-barstar-bar gene system.

    • This system enables the production of high-yielding hybrid mustard seeds by preventing self-pollination and allowing cross-pollination between parent lines.

  • Yield Gains:

    • Field trials suggest 20–30% higher yields compared to conventional mustard varieties.

    • Higher productivity could directly boost domestic edible oil production.

  • Development Timeline:

    • Research began in 2002, with nearly 14 years of R&D before regulatory submissions.

    • It has since undergone confined field trials, bio-safety testing, and regulatory evaluations.

Economic & Market Significance

  • India’s Edible Oil Deficit:

    • India imports ~14–15 million tonnes of edible oil annually, costing over USD 10–12 billion.

    • A successful rollout of DMH-11 could reduce import dependency and support farmer income.

  • Farmer Benefits:

    • Higher yields → improved profitability.

    • Reduced vulnerability to global oilseed price shocks.

  • Potential Market Impact:

    • Could stimulate domestic oilseed processing industries.

    • May encourage the adoption of GM technologies in other food crops if successful.

Policy & Regulatory Journey

  • Regulatory Hurdles:

    • The Genetic EngineeringAppraisal Committee (GEAC) cleared DMH-11 for environmental release in 2017, but commercialization was delayed due to legal challenges and public protests.

    • In October 2022, GEAC again recommended environmental release, renewing debates around GM crops.

  • Opposition & Concerns:

    • Environmental groups and farmer unions argue GM mustard could harm biodiversity, threaten native mustard varieties, and increase dependence on multinational seed companies.

    • Health & Environmental Safety: Concerns raised about pesticide resistance and long-term ecological impacts, despite official biosafety trials indicating safety.

  • Government Stance:

    • The Indian government has positioned DMH-11 as a strategic tool for food security and import substitution, though political and judicial challenges persist.

Environmental & Social Dimensions

  • Biodiversity Concerns: Potential cross-pollination with wild relatives could threaten genetic purity.

  • Pesticide Debate: Critics fear GM mustard may increase the use of herbicides like glufosinate.

  • Food Sovereignty: Debate centers around seed sovereignty, whether farmers will remain dependent on proprietary seeds or benefit from public-sector innovation (since DMH-11 is developed by a public university, not a multinational corporation).

Future Outlook

  • Commercialization Path: If DMH-11 clears final legal and regulatory hurdles, it could be India’s first commercially approved food GM crop, after Bt cotton (fiber) and Bt brinjal (which remains under moratorium).

  • Scaling Impact: Adoption across mustard-growing states like Rajasthan, Haryana, Madhya Pradesh, and Uttar Pradesh could significantly raise domestic edible oil production.

  • Policy Ripple Effects: Success of DMH-11 may open doors for other transgenic food crops (rice, wheat, pulses), accelerating India’s entry into modern agri-biotech.

Key Takeaways

  1. DMH-11 represents a milestone in Indian GM crop research—14 years of R&D in a public institution.

  2. It promises 20–30% higher yields, addressing India’s USD 10–12 billion edible oil import bill.

  3. The project faces regulatory, legal, and social resistance, particularly around biosafety, biodiversity, and seed sovereignty.

  4. If approved for commercialization, DMH-11 could reshape India’s GM crop policy and spark wider biotech adoption.

  5. Its outcome will influence the future of food security, farmer livelihoods, and biotechnology regulation in India.
