Because they are a source of resistance to, or tolerance of, biotic and abiotic stresses, the most important use of the various species of wild rice is probably in breeding programmes to improve the species of cultivated rice (Oryza sativa, Oryza glaberrima). However, many are also valuable for use as food supplements and as famine foods when other crops fail. In many parts of South Asia, wild rice grains are used as an offering to Deities in the temples and can command a high price in the market where they are sold during religious festivals. This species is a kind of holy plant in Myanmar, and is protected within the sanctuaries of Buddhist temples. The plant is also used medicinally in China)[

Edible Uses

The red pericarp present in nearly all wild species is favoured by ethnic tribes and some urban people as having nutritional increments or is used for decorative purpose during festivities. On the other hand, if found in commercial lots, the red seed-coat carried by primitive cultivars lowers the grade of milled rice[
