Which are the two main kinds of rice in the world?
There are three main varieties of Oryza sativa:
Indica: The indica variety is long-grained, for example Basmati rice, grown notably on the Indian sub-continent.
Japonica: Japonica rice is short-grained and high in amylopectin (thus becoming “sticky” when cooked), and is grown mainly in more temperate or colder regions such as Japan.
Javonica: Javonica rice is broad-grained and grown in tropical climates.
