Oryza ridleyi Hook. F.

Abstract

Although rice is life of human from the civilization and conventional breeding has contributed immensely to improve the rice cultivar. Yet due to the climate change and high demand of paddy for food security, improved cultivar of rice is required. While extensive research has been conducted with the exciting gene pool of rice, wild species of rice is now of paramount importance. Thus, in this chapter we tried to describe one such little-known species Oryza ridleyi and its importance and economic benefits, which gives us the opportunity to search more accurately within the genes and benefit from the pursuit of environmental development. economic importance due to the presence of several tolerant genes for various biotic and abiotic stress. For an example, Padhi and Sen (2002) reported that O. ridleyi is tolerant to yellow stem borer. Oryza ridleyi has various agronomically important genes such as adaptation to aerobic soil and salinity tolerance, and resistance to bacterial blight, blast and stem borer (Khush 1997; Brar and Khush 1997; Ge et al. 1999).
