Japonica rice
Japonica rice (Oryza sativa subsp.Japonica rice originated from Central China, where it was first domesticated along the Yangtze River basin approximately 9,500 to 6,000 years ago.[5] Temperate japonica is cultivated in East Asia (China, Japan, Korea, and Vietnam), while tropical japonica is in Indonesia, Madagascar, and also the Americas where it was brought to with slave trade.[6] Japonica rice grains are rounder, thicker, and harder, compared to longer, thinner, and fluffier indica rice grains.Japonica rice is also stickier due to the higher content of amylopectin, whereas indica rice starch consists of less amylopectin and more amylose.
