International Hybrid Rice
Symposium 2017

7 - 9 November 2017   Aston Denpasar Hotel & Convention Center, Bali, Indonesia

About The Symposium

The International Hybrid Rice Symposium (IHRS) is a quadrennial event convened by the International Rice Research Institute (IRRI) in partnership with a host country that provides an international discussion platform on hybrid rice development. The event brings together public institutions and private organizations from different countries engaged in hybrid rice research and development.

The last International Hybrid Rice Symposium was held at Taj Krishna Hotel, Hyderabad, India on September 2012 hosted by the Indian Council for Agricultural Research (ICAR), jointly organized by the International Rice Research (IRRI) and Directorate of Rice Research (DRR). It was attended by 440 leading hybrid rice researchers, representatives from public and private organizations, and industry experts from 32 countries. The symposium discussed future rice strategies and reviewed current knowledge on hybrid rice development, seed production, molecular applications, crop and resource management, and economics.

Description of Hybrid Rice Parallel Sessions

Hybrid Rice Genetics and Breeding

This session tackles the scientific breakthroughs on the parental line improvement including new developments, methodologies and approaches used by breeders. The genetics involved in the trait breeding pertaining to higher outcrossing, combining ability, grain quality, abiotic stress tolerances, and insect pest and disease resistance. Breeding for higher heterosis for grain yield and understanding its genetics will be covered

Seed Production

Increasing hybrid rice seed production efficiency through use of improved management techniques. Approaches to make it cost effective. Improving management control in flowering synchronization of parental lines. In this session, presenters will talk about new scientific techniques that can reduce seed production costs.

New Technology Applications

Recent advances in genomics and molecular breeding is opening up new avenues for improvement of the hybrid rice technology. Genome editing tools and their utilization in hybrid rice technology. Novel approaches to enhancing the heterosis and seed production efficiency will be captured in this session.

Crop & Resource Management

Higher yields of hybrids are affected by various crop management, numerous agronomic practices and cultivation technologies. This session will focus on current studies that look into how heterosis is optimized through proper crop management, irrigation techniques and mechanization.

Hybrid Rice Economics

One of the fundamental questions in hybrid rice development is if higher yields of hybrids translates to more income and benefits to rice farmers. This session will look into current challenges in applicability, costs, re-uptake of technology and adoption among farmers. This session will also look into the economics of hybrid rice seed production to make it viable for the seed industry.

National Policies and Public-Private Engagement on Hybrid Rice

Both public and private sectors are investing in hybrid rice development. This session will look into the existing national policies and the current sphere of investments in hybrid rice development that enables promotion of the R& D and use of hybrid rice varieties by small farmers. This session will be able to identify ideal set of policy initiatives that need to be taken up for deployment of hybrid rice technology.
