Manila – A new international research initiative, linking the private and public sectors for the first time and launched on November 9 at the 2007 Asian Seed Congress, aims to boost the research and development of hybrid rice for the tropics.

The Hybrid Rice Research and Development Consortium (HRDC), established by the International Rice Research Institute (IRRI), will strengthen public–private sector partnership in hybrid rice, a technology that can raise the yield of rice and thus overall rice productivity and profitability in Asia.

Hybrid rice takes advantage of the phenomenon of hybrid vigor—known as heterosis—to achieve yields 15–20% higher than nonhybrid (inbred) varieties. Over the past three decades, the technology has helped China achieve food security, but has not yet reached its potential in the tropics.

IRRI and its partners in the public and private sector have led research on development of, and use of, hybrid rice technology in the tropics for almost 30 years. Successful deployment of hybrid rice in Asia, however, requires more effective cooperation between public research institutions and the private sector in research to overcome current constraints.

The HRDC will be hosted by IRRI and will have three major objectives:

  • Support research on developing new hybrids with enhanced yield heterosis, improved seed production, multiple resistances to stresses, and grain quality.

  • Support research on best management practices for rice hybrids.

  • Improve information sharing, public awareness, and capacity building.

Public and private sector organizations and companies with interest in hybrid rice development are invited to become members of the HRDC. For private-sector members, annual financial contributions under the consortium structure will take into account the status of seed companies at different stages of development. HRDC members will have access to improved parents, hybrids, and breeding lines, including seeds and associated information.

The HRDC will have a public–private sector advisory committee and will meet annually to provide information to its members on new plant genetic resources available or under development, review research on hybrid rice management, discuss new research priorities, and make decisions on other consortium activities such as capacity building for both the public and private sectors.

According to IRRI senior hybrid rice researcher Fangming Xie, the HRDC will significantly enhance the capacity for hybrid rice research and product delivery, while providing services and support to the private sector in its product development and delivery that will benefit the general public.

“National agricultural research and extension systems and other public sector organizations engaged in hybrid rice research and development will be among the primary beneficiaries of funds generated by the HRDC”, said Dr. Xie. “Rice farmers in Asia will benefit from accelerated access to hybrid rice-based technologies such as more and better hybrids, good-quality seed, knowledge, and services provided by the private and public sectors.”

The International Rice Research Institute (IRRI) is the world’s leading rice research and training center. Based in the Philippines, with offices in 13 other countries, IRRI is an autonomous, nonprofit institution focused on improving the well-being of present and future generations of rice farmers and consumers, particularly those with low incomes, while preserving natural resources. IRRI is one of 15 centers funded through the Consultative Group on International Agricultural Research (CGIAR), an association of public and private donor agencies (
