Species Information


























































Common name:       Rice

Scientific name:         Oryza sativa-indica

Chinese name:        籼稻

Taxonomy

       Angiosperms/Monocotyledoneae/Gramineae/Oryza/Oryza sativa

Overview

       Oryza Sativa is one of the oldest crop species in the world. Asian cultivated rice originated in China and appeared as early as 8,000 years ago in China's Yangtze River valley, US researchers have confirmed in a study of the evolution of rice through large-scale gene resequencing.
       The character of indica rice is close to that of its ancestor wild rice, so some scholars believe that indica rice is the basic type and japonica is the variant type. Indica rice is suitable for planting in hot and humid areas at low latitude and altitude, and its grains are easy to fall off. It is resistant to humidity, heat and intense light, but not cold. Japonica rice is more suitable for high latitude or low latitude high altitude planting, grain is not easy to fall off, more cold resistance, weak light resistance, but not high temperature resistance, so the middle and lower reaches of the Yangtze River in China after the double rice area and the North of the Yellow River generally use japonica rice varieties.
