Oryza officinalis is species of flowering plant in the genus Oryza (rice) native to India, Nepal, the eastern Himalaya, southeast Asia, south-central and southeast China, Hainan, the Philippines, New Guinea, and the Northern Territory and Queensland in Australia.[2] A perennial diploid with the CC rice genome, it can reach 3 m (10 ft) in height.[3] It is the namesake of a widespread species complex.[4]
Pests
O. officinalis in Sukhothai Province, Thailand was reported in 1990 to be highly resistant to tungro and various other pests, and already in use in several cultivars.[IRRI 1][Bon 1]

Results from recent research indicate that resistance to RTD is present in many wild rice species (R. Ikeda, personal communication), and perhaps some will show resistance to RTBV."
