When it should be used
Conservation of rice seed material under cold (between 2 and -20oC) and dry (moisture content of 6-7% fresh weight) storage is the most common, efficient and cheapest means of conservation of rice genetic resources. There are about 20 000 samples of wild rice seeds and related genera conserved in seed banks worldwide. The largest collections of wild rice and related genera are housed at CAAS, China and IRRI, the Philippines.
- Should be used for any rice accessions and species that produce seeds that remain viable under the standard cold and dry seed storage conditions.
