More on this exam

India becomes the first country globally to develop rice varieties using genome editing technology. New seeds to be available to farmers within 6 months post-clearance, large-scale production expected in next 3 crop seasons.

New Rice Varieties Developed

Variety NameParent VarietyKey Traits & Benefits
DRR Dhan 100 (Kamala)Samba Mahsuri (high-yield green rice)– Yield: 5.37 tonnes/ha (vs 4.5 parent) – Drought tolerant – High nitrogen use efficiency – 20 days earlier maturity (saves water, fertilizer, lowers methane)
Pusa DST Rice 1Maruteru 1010 (MTU1010)– 9.66% higher yield under inland salinity stress – 14.66% higher under alkalinity – 30.4% higher under coastal salinity stress

Technology Used

  • Genome Editing Techniques: Site-Directed Nuclease 1 and 2 (SDN-1, SDN-2).
  • Not Genetically Modified (GM): No foreign genes introduced (unlike SDN-3).
  • Mutations mimic natural mutation processes.
  • Recognized and approved internationally.
  • Research tested during 2023-24 under All India Coordinated Research Project on Rice.
  • Peer-reviewed paper on Pusa DST Rice 1 published in 2020; Kamala’s paper under publication.

Controversies & Concerns

  • Farmers’ Representative Criticism: Venugopal Badaravada called the claims premature; was expelled from ICAR governing body.
  • Activist Opposition: Coalition for a Genetically Modified-Free India opposes deregulation, citing safety concerns and legal issues.
  • Seed Sovereignty Issues: Fears about Intellectual Property Rights (IPR) on gene editing technology affecting farmers’ control over seeds.
  • Demand for Transparency: Calls for government disclosure on IPR status and regulatory clarity.
