Hybrid rice + innovations: a path forward for climate-smart agriculture

January 7, 2025 | International Rice Research Institute (IRRI) |

 

A recent study “Advanced technologies for reducing greenhouse gas emissions from rice fields: Is hybrid rice the game changer?”, published in Plant Communications by researchers from IRRI, USDA, and the University of the Philippines Los Baños (UPLB), highlights hybrid rice as a promising solution to reduce greenhouse gas (GHG) emissions while ensuring food security. The study shows hybrid rice emits 19% less methane due to its shorter growth duration and enhances nitrogen-use efficiency, reducing nitrogen emissions. Innovations such as machine learning, gene editing, and high-throughput phenotyping further accelerate climate-resilient rice breeding. Integrating hybrid rice with nutrient optimization, controlled irrigation, and soil organic matter management could significantly lower emissions while improving productivity. However, understanding plant genetics, soil microbiota, and environmental interactions remains a challenge, and widespread adoption will require research, farmer incentives, and policy support.
