Introduction
The controversy over India’s indigenously developed genetically modified (GM) mustard — Dhara Mustard Hybrid-11 (DMH-11) — reflects the complex intersection of science, health, economy, and governance. While DMH-11 promises higher yields and lower erucic acid content in mustard oil, concerns persist over its biosafety, ecological impact, and regulatory transparency. India, being a signatory to the Cartagena Protocol on Biosafety, must balance scientific advancement with public confidence, environmental sustainability, and constitutional accountability.
Scientific and Economic Significance of DMH-11
- Nutritional and Health Benefits: Traditional mustard oil in India contains 40-54% erucic acid, well above the <5% global safety threshold. High levels are linked to cardiac and liver issues in animal studies. DMH-11 reduces erucic acid to 30-35%, aligning it closer to international standards and potentially improving public health.
- Economic Advantage: India is the world’s largest importer of edible oils, with an import bill exceeding $20 billion (NITI Aayog, 2024). A high-yield, low-erucic acid mustard could reduce this burden. Higher domestic yields (by 25-30%) also align with the government’s goal of doubling farmers’ income and achieving oilseed self-reliance (Atmanirbharata).
- Agronomic Merits: DMH-11 uses the barnase-barstar gene system for hybrid vigour, enabling higher productivity. Trials by the Indian Council of Agricultural Research (ICAR) suggest yield gains without adverse agro-ecological impact.
Governance and Regulatory Dilemmas
- Regulatory Fragmentation: India’s biotech governance is overseen by multiple bodies — GEAC (Genetic Engineering Appraisal Committee), FSSAI, and the Environment Ministry — leading to overlaps, delays, and lack of coordination. The Supreme Court (2024) withheld environmental release, citing insufficient health impact assessments, exposing regulatory gaps.
- Lack of Transparency and Public Participation: Critics allege non-disclosure of full biosafety data, limited stakeholder consultations, and inadequate risk communication, fueling distrust. Civil society and farmer groups demand independent, peer-reviewed evidence, not solely developer-led trials.
- Policy Inconsistency: While Bt cotton is widely cultivated (95% of India’s cotton area), GM food crops like brinjal and mustard face moratoriums, reflecting incoherence in biotech policy. The absence of a comprehensive GM crop policy or biosafety law further complicates approvals and oversight.
Balancing Risks and Sustainability
- Scientific Rigor: Robust, multi-location, long-term field trials with transparent data sharing must be institutionalized. An autonomous biosafety authority, as recommended by the Parliamentary Standing Committee (2017), could ensure credibility and insulation from political influence.
- Environmental Concerns: Cross-pollination risks to wild relatives of mustard, impact on pollinators (especially bees), and herbicide tolerance traits demand ecological risk management.
- Alternative Approaches: Conventional breeding, CRISPR-based gene editing, and marker-assisted selection (non-transgenic) can offer safer and publicly acceptable alternatives.
Conclusion
The DMH-11 episode epitomizes the challenges of integrating science with policy in a democratic, diverse society. India needs a coherent, transparent, and evidence-based regulatory framework that encourages innovation while safeguarding public health, ecology, and farmers’ rights. Trust-building through scientific integrity and participatory governance is crucial for the sustainable adoption of GM technology.
