Oryza sativa, having the common name Asian cultivated rice, [2] is the much more common of the two rice species cultivated as a cereal, the other species being O. glaberrima, African rice. It was first domesticated in the Yangtze River basin in China 13,500 to 8,200 years ago.

3 days ago · rice, (Oryza sativa), edible starchy cereal grain and the grass plant (family Poaceae) by which it is produced. Roughly one-half of the world population, including virtually all of East and Southeast Asia, is wholly dependent upon rice as a staple food; 95 percent of the world’s rice crop is eaten by humans.

The scientific name for rice is Oryza. Oryza sativa is the most common species and is subdivided into the long-grain indica, and short-grain japonica. Tools for farming rice have been found in China dating back 8000 years. Merchant traders helped the gradual spread of rice across the continents. Source Of* (*primarily whole grain varieties) Fiber

Oryza glaberrima, commonly known as African rice, is one of the two domesticated rice species. [1] It was first domesticated and grown in West Africa around 3,000 years ago. [2] [3] In agriculture, it has largely been replaced by higher-yielding Asian rice , [2] and the number of varieties grown is declining. [1]

ORYZA is a crop model for rice, which embodies more than 30 years of global research. IRRI has been involved in crop modeling since the 1970s, and has participated in the Simulation and Systems Analysis for Rice Production (SARP) Project from mid-80s to mid-90s.

Oryza is a genus of plants in the grass family. [3] [4] It includes the major food crop rice (species Oryza sativa and Oryza glaberrima). Members of the genus grow as tall, wetland grasses, growing to 1–2 metres (3–7 ft) tall; the genus includes both annual and perennial species. [5]

Asian rice is one of only two cultivated types of rice, along with African rice (Oryza glaberrima). It is an extremely versatile plant that is used in countless dishes, medicines, cosmetics, and crafts.

Weedy rice is highly variable and thought to originate from outcrosses to wild species (O. nivara, O. rufipogon) or as a result of outcrossing within domestic rice. It is distinguished by the key weedy traits of ready panicle shattering and variable secondary dormancy.
