Abstract
Rice is the primary dietary source of energy for nearly half of the world’s population. Rice genetic improvement is the need of the hour to feed the world’s growing population. Wild rice species are treated as a useful source of genetic variability for different important traits. Besides two cultivated rice species (Oryza sativa and Oryza glaberrima), there are a total of 24 wild species belong to four species complex, viz. Sativa, Officinalis, Ridleyi and Meyeriana. This chapter deals with the most unexplored wild rice species Oryza neocaledonica, an endemic and endangered species with very few known populations. The species belongs to Meyeriana complex and is only confined to an island, Neo Caledonia of southwest Pacific Ocean. Scientific study subjected to O. neocaledonica is rarely available. This member of tertiary gene pool of rice could be proved as a valuable genetic resource for drought tolerance as it grows in much lesser water than that is required by cultivated rice.
