There are three wild rice germplasm resources in China. Compared with Oryza rufipogon and Oryza officinalis， Oryza granulata exhibits more distinct scarcity and endangerment status and utmost importance in protection. At present， the research on the theory of wild rice conservation and the development of conservation technology are relatively lagging behind， and there is a lack of standardized technical guidelines， which results in insufficient support for both ex-situ and in-situ conservation. Based on the results of many years of investigation and experiments， the standard technical regulation for ex-situ conservation of Oryza granulata resources was summarized and normalized. It mainly includes the saving procedures， acquisition of germplasm samples， trial planting and observation， cataloging and organization， ex-situ conservation， planting in the field， field management， monitoring， harvesting， rejuvenation and propagation， distribution， germplasm information. Our study provides technical reference for ex-situ conservation of Oryzagranulata resources. The technical regulations are applicable to ex-situ conservation of Oryza granulata resources.
