Abstract

Rice is the staple food of more than half of the world’s population, and its present cultivation spans from latitude 53° N to 40° S (Lu and Chang 1980), from -23 to +7000 feet above sea level. It is cultivated under various conditions, including upland, deep water, and soils with pH 3.5 to 9.5 (Khush 1984). There are 22 species in the genus Oryza, most of which are diploid (2n = 24), and seven species are tetraploid (4n = 48) (Chang 1985). O. sativa L. and O. glaberrima Steud are the two cultivated species. O. sativa is usually divided into three eco-species: indica, japonica (sinica), and javanica.
