International Hybrid Rice Symposium


Heralding an era of low carbon footprint hybrids



The International Hybrid Rice Symposium (IHRS) is a meeting spearheaded by IRRI’s Hybrid Rice Development Consortium (HRDC) and is held every 4 years. Attended by 300-500 experts in the field of hybrid rice, IHRS is being conducted in different countries and coordinated with the host government’s rice research institution. It aims to provide the latest scientific knowledge among its members and fellow researchers specializing in and studying hybrid rice and related concepts. It also serves as a platform to discuss the challenges in hybrid rice research and its adoption.


This year, the IHRS theme “Heralding an era of low carbon footprint hybrids” focuses on the effect of rice production on climate change, with a special emphasis on carbon footprint. Rice production is both affected by and a contributor to climate change. The inputs used and the management practices applied contribute to the increasing greenhouse gas emissions across the globe. HRDC, which engages with both private and public institutions, promotes climate-resilient hybrid rice that can withstand the effect of climate change. Previous editions of IHRS include Changsha, China (1986 and 2008), Manila, Philippines (1994), Hyderabad, India (1996 and 2012), Hanoi, Vietnam (2003), and Yogyakarta, Indonesia (2018).
