Brief"Red List Category & Criteria: Least Concern ver 3.1 Year Assessed: 2010 Assessor/s: Watve, A. Reviewer/s: Juffe Bignoli, D., Narasimhan, D., Ravikumar, K., Rao, M.L.V. & Kumar, V.S. Contributors: Molur, S. Justification: Oryza rufipogon is the wild species from which the cultivated rice, Oryza sativa, has been domesticated. It is wide spread in most of the world, being invasive in parts of America. It is considered a weed in rice fields, as it easily crosses with the cultivated rice, reducing its market value. No serious threats have been reported for the species and hence it is included in the category Least Concern. It is important for the germplasm which has many resistant genes, and hence is collected and conserved in-situ and ex-situ in China. Conservation Actions: It is considered important to conserve germplasm of this species as ancestor of cultivated rice. In China, a program on in-situ conservation has been started.
