International Rice Genebank

International Rice Genebank. It is the world's largest and most comprehensive repository of rice genetic diversity, serving as a global public good for food security. Operated by the International Rice Research Institute at its headquarters in the Philippines, the genebank's primary mission is to conserve the genetic heritage of rice for current and future generations. Its extensive collection supports breeding programs and scientific research worldwide to develop improved, resilient rice varieties.

History and establishment

The foundation for the genebank was laid with the establishment of the International Rice Research Institute in 1960, which began assembling rice samples from across Asia. A formal seed storage facility was inaugurated in 1977 with support from the United Nations Development Programme and the Government of Japan. Its creation was driven by growing recognition, highlighted in forums like the Food and Agriculture Organization, of the need to conserve crop wild relatives and traditional landraces facing genetic erosion. Over the decades, its mandate was strengthened by international agreements such as the International Treaty on Plant Genetic Resources for Food and Agriculture, designating it a global center for rice conservation.

Collection and conservation

The collection encompasses over 130,000 accessions of cultivated rice (Oryza sativa and Oryza glaberrima) and their wild relatives from more than 140 countries. This includes traditional varieties, modern breeding lines, and crucial genetic resources from the primary centers of diversity in regions like the Ganges Delta and the Mekong Delta. Conservation follows rigorous scientific protocols for seed viability testing, cryopreservation, and in vitro storage, with duplicate samples stored in the Svalbard Global Seed Vault. The genebank also maintains a living collection of species with recalcitrant seeds at the International Rice Research Institute farm.

Research and utilization

Scientists at the International Rice Research Institute and partner institutions conduct extensive characterization of accessions for valuable traits such as tolerance to biotic stress like blast disease and brown planthopper, and abiotic stress including drought and salinity. Genomic studies, often utilizing techniques developed from the Rice Genome Project, help identify genes for yield potential and nutritional quality. The germplasm is freely distributed under the Standard Material Transfer Agreement to researchers globally, leading to varieties like Swarna-Sub1 and contributing to initiatives such as the Green Revolution and the C4 Rice Project.

Management and operations

Day-to-day operations are managed by a dedicated team of genetic resources specialists, curators, and technicians at the International Rice Research Institute. The genebank's activities are guided by a management committee and adhere to quality standards set by the Food and Agriculture Organization and the Consultative Group on International Agricultural Research. Key processes include seed health testing, regeneration of accessions in screenhouses, and meticulous data management through the International Rice Genebank Collection Information System. Financial and strategic support comes from donors like the World Bank and the Government of Norway.

Global impact and partnerships

The genebank is a cornerstone of international efforts to safeguard agricultural biodiversity and adapt to climate change. It actively collaborates with national programs like the Indian Council of Agricultural Research and the Chinese Academy of Agricultural Sciences, as well as global entities including the Global Crop Diversity Trust and Bioversity International. Its resources were instrumental in post-disaster recovery, such as restoring rice diversity in Mozambique after floods. By providing the raw genetic material for innovation, it underpins food security for millions dependent on rice production across Africa, Latin America, and Asia.
