UPSC Syllabus: GS 3- Indian Economy<\/strong><\/p>\n

Context:<\/strong> India is preparing to commercially introduce Pusa Rice DST1<\/strong> in the upcoming rabi season, marking an important step in the application of genome-editing technology to agriculture. Along with DRR Dhan 100 (Kamala)<\/strong>, it represents an attempt to improve productivity and climate resilience in rice cultivation.<\/p>\n

Key developments<\/strong><\/h2>\n
    \n
  1. Pusa Rice DST1<\/strong> has been developed by ICAR-IARI from the MTU1010 variety.<\/li>\n
  2. It involves SDN-1 genome editing<\/strong> of the Drought and Salt Tolerance (DST) gene<\/strong> to improve tolerance to drought and saline or alkaline soils.<\/li>\n
  3. Field trials reported 9.66%\u201330.4% yield advantages<\/strong> over MTU1010 under different saline and alkaline conditions.<\/li>\n
  4. DRR Dhan 100 (Kamala)<\/strong> was developed by ICAR-Indian Institute of Rice Research from Samba Mahsuri.<\/li>\n
  5. Its gene editing targets a gene involved in cytokinin metabolism<\/strong>, increasing grains per panicle.<\/li>\n
  6. Kamala matures in around 130 days<\/strong>, approximately 20 days earlier than Samba Mahsuri, and has stronger stems that reduce lodging.<\/li>\n<\/ol>\n

    Why does it matter?<\/strong><\/h2>\n
      \n
    1. The varieties can improve productivity and resource-use efficiency<\/strong>.<\/li>\n
    2. Pusa DST1 can help farmers cope with drought and soil salinity<\/strong>.<\/li>\n
    3. Kamala\u2019s shorter duration can reduce the crop cycle and potentially conserve resources.<\/li>\n
    4. Climate-resilient varieties can strengthen India\u2019s agricultural response to climate change<\/strong>.<\/li>\n
    5. Wider cultivation can potentially benefit farmers across several States, including Andhra Pradesh, Telangana, Karnataka, Tamil Nadu, Uttar Pradesh and West Bengal.<\/li>\n<\/ol>\n

      Gene editing versus GM crops<\/strong><\/h2>\n
        \n
      1. GM crops<\/strong> generally involve introducing genetic material from another organism into the plant.<\/li>\n
      2. Genome editing<\/strong> can make targeted changes in genes already present in the plant.<\/li>\n
      3. SDN-1<\/strong> generally produces small insertions or deletions, while SDN-2<\/strong> introduces a specific small change using a repair template.<\/li>\n
      4. SDN-3<\/strong> can introduce a new genetic sequence and remains outside the exemption applicable to SDN-1 and SDN-2.<\/li>\n
      5. India\u2019s 2022 guidelines<\/strong> exempted qualifying transgene-free SDN-1 and SDN-2 plants from the more rigorous regulatory process applicable to SDN-3.<\/li>\n
      6. Both new rice varieties are SDN-1 edited and transgene-free<\/strong>.<\/li>\n<\/ol>\n

        Concerns<\/strong><\/p>\n

          \n
        1. The absence of foreign DNA does not automatically establish that the crop has no unintended effects<\/strong>.<\/li>\n
        2. Unintended mutations could potentially alter gene functioning, biochemistry, nutritional characteristics, toxins or allergens.<\/li>\n
        3. The reported yield gains need to be assessed across different environments and farming conditions<\/strong>.<\/li>\n
        4. High yield gains in one trait could involve trade-offs in other traits<\/strong>.<\/li>\n
        5. Wider scientific scrutiny is required regarding the mechanism behind the reported yield advantages<\/strong>.<\/li>\n
        6. Farmers and consumers need transparent information regarding biosafety, performance and long-term effects<\/strong>.<\/li>\n
        7. The experience of GM crops such as Bt cotton, Bt brinjal and GM mustard<\/strong> shows that technological adoption also involves ecological, regulatory and socio-economic concerns.<\/li>\n<\/ol>\n

          Regulatory and global context<\/strong><\/h2>\n
            \n
          1. The government states that the rice varieties underwent biosafety scrutiny for absence of foreign DNA, mutation stability and robustness of traits<\/strong>.<\/li>\n
          2. Each variety was reportedly tested at more than 50 locations during 2023\u201324<\/strong>.<\/li>\n
          3. India currently permits Bt cotton<\/strong> as its only GM crop for commercial cultivation.<\/li>\n
          4. Bt brinjal completed the regulatory process but was not commercially approved, while GM mustard received conditional environmental clearance and became subject to legal challenges.<\/li>\n
          5. Globally, countries are developing separate regulatory approaches for transgene-free gene-edited crops.<\/li>\n
          6. The US, Canada and Japan<\/strong> have permitted certain gene-edited crops or foods.<\/li>\n
          7. The UK introduced a separate precision-breeding framework, while the EU adopted a new framework for New Genomic Techniques in 2026<\/strong>, including a category for crops involving changes that could occur naturally.<\/li>\n<\/ol>\n

            Way forward<\/strong><\/h2>\n
              \n
            1. India should undertake long-term, multi-location field evaluation<\/strong> before large-scale adoption.<\/li>\n
            2. Regulatory decisions should be based on transparent and independently scrutinised scientific evidence<\/strong>.<\/li>\n
            3. Biosafety assessment should examine unintended mutations, nutritional changes, allergens and ecological effects.<\/li>\n
            4. Farmers should receive adequate information, extension support and access to quality seeds.<\/li>\n
            5. Public research institutions should make relevant scientific evidence available for wider peer and scientific scrutiny<\/strong>.<\/li>\n
            6. Regulation should remain risk-based and technology-neutral<\/strong>, distinguishing gene editing from transgenic GM technology without compromising biosafety.<\/li>\n<\/ol>\n

              Conclusion: <\/strong>Gene-edited rice can become an important tool for making Indian agriculture more productive, climate-resilient and resource-efficient<\/strong>. However, its success should not be judged only by higher yields. A combination of scientific transparency, rigorous biosafety assessment, multi-location testing, farmer participation and proportionate regulation<\/strong> is essential for ensuring that genome editing delivers sustainable benefits to Indian agriculture.<\/p>\n

              Question: <\/strong>\u201cGene-edited rice represents a significant opportunity for India to improve agricultural productivity and climate resilience, but its commercialisation must be accompanied by robust scientific assessment and regulatory oversight.\u201d Discuss with reference to India\u2019s gene-edited rice varieties.<\/p>\n
