The Indian Council of Agricultural Research (ICAR) has successfully developed the world's first genome-edited (GE) rice varieties that promise superior yields and increased resilience against drought and salinity. These advancements were achieved through the efforts of the Indian Institute of Rice Research (IIRR) and the Indian Agricultural Research Institute (IARI) using cutting-edge CRISPR-Cas SDN-1 gene editing technology. Union Minister of Agriculture and Farmers’ Welfare, Shivraj Singh Chouhan, launched these varieties at the ICAR’s NASC Complex.

Key Highlights of the Development:

• Genomic Editing vs. Genetic Modification: The GE rice varieties differ from traditional genetic modification (GM) in that they edit existing genes within the plant rather than introducing foreign genes. This involves modifying the native genetic code using CRISPR-Cas, which functions as molecular scissors to effect these changes.

• Samba Mahsuri Rice Variety: The first GE variety, known as IET-32072 or 'Kamala', is derived from the widely cultivated Samba Mahsuri (BPT-5204). It exhibits:

  • An average paddy yield of 5.37 tonnes per hectare, which is a significant increase compared to 4.5 tonnes from the parent variety.
  • Shorter maturation time (around 130 days), allowing for earlier harvesting while preserving grain quality.

• Cottondora Sannalu Rice Variety: The second GE variety, IET-32043 or Pusa DST Rice 1, comes from the Cottondora Sannalu (MTU-1010) strain. It offers:

  • Improved tolerance against drought and salinity, making it suitable for stress-prone areas.
  • Yield improvements of 3.508 tonnes per hectare under inland salinity conditions, surpassing the yields of its parent strain.

Regulatory Status and Future Implications:

• The Indian government has exempted GE crops from certain biosafety regulations that typically govern GM crops, streamlining the process for field trials and commercialization. The marshaling of these regulatory relaxations signifies a recognition of the potential benefits posed by GE technology.

• Multi-location field trials of the new GE rice varieties were conducted in 2023 and 2024, leading to their approval based on findings that they lack foreign DNA. This could open avenues for advancing GE technology across other crops like oilseeds and pulses.

• Funding for this initiative has been supported by the Union Budget, which allocated ₹500 crore for GE breeding and agricultural research.

Intellectual Property Concerns:

• Despite the advances, the ICAR acknowledged ongoing issues concerning intellectual property rights (IPR) associated with the CRISPR-Cas9 technology, which is patented by the Broad Institute of MIT and Harvard. ICAR is actively addressing these IPR concerns.

Conclusion:

The development of these genome-edited rice varieties marks a significant leap in agricultural biotechnology in India, advocating for higher yields, resilience to climate change, and improved crop quality. This initiative not only illustrates the potential of CRISPR technology in crop breeding but also sets a precedent for further research and application in various agricultural sectors.
