Rice, one of the most important cereal crop, is the staple food for more than half the world's population. Future crop improvement needs the genetic variation from traditional varieties and related wild species to cope with the many biotic and abiotic stresses around the world. Established in 1977, the IRRI genebank has conserved more than 109,000 accessions including 5,000 accessions of wild. All introduced germplasms are multiplied after the necessary quarantine check by IRRI's Seed Health Unit. Multiplication and regeneration are carried out only during the dry season between the end of October and March with the consideration of ecotype to produce seeds with the highest quality. A sufficient quantity of high qualified seeds are stored in base and active collections for long-term and medium-term conservation, respectively. Germplasms are also conserved at the NCGRP(National Center for Gegenetic resources Preservation), USA and SGSV(Svalbard Global Seed Vault), Norway as a safety back-up. The decision to regenerate germplasm accessions depends equally upon the viability and quantity of seeds held in storages. Germplasms are available freely on request to bona fide researchers in both public and private sector institutions and farmers. An integrated information system is linked to all operations associated with germplsam conservation and management.
