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). The seed of this species is also sometimes harvested from the wild for local use as a food.
