Rice is the seed of the grass species Oryza sativa or less commonly O. glaberrima. The name wild rice is usually used for species of the genera Zizania and Porteresia, both wild and domesticated, although the term may also be used for primitive or uncultivated varieties of Oryza.
Oryza sativa, commonly known as Asian rice or indica rice, is the plant species most commonly referred to in English as rice. It is the type of farmed rice whose cultivars are most common globally, and was first domesticated in the Yangtze River basin in China 13,500 to 8,200 years ago.
Basmati, pronounced ['bɑːsmət̪iː], is a variety of long, slender-grained aromatic rice which is traditionally grown in India, Pakistan, and Nepal. As of 2019, India accounted for 65% of the international trade in basmati rice, while Pakistan accounted for the remaining 35%. Many countries use domestically grown basmati rice crops; however, basmati is geographically exclusive to certain districts of India and Pakistan.
Black rice, also known as purple rice or forbidden rice, is a range of rice types of the species Oryza sativa, some of which are glutinous rice.
Patna rice, a variety of the species Oryza sativa, and one of the varieties of long-grain white rice, is extensively cultivated in the Indo-Gangetic plains, in and around Patna, capital of Bihar state, India. Patna rice is known for its elongated kernel with grain length greater than 6 mm, and has been used as staple food by the local people for thousands of years. Sometimes, Patna rice is also called Parimal rice locally.
Jasmine rice is a long-grain variety of fragrant rice. Its fragrance, reminiscent of pandan and popcorn, results from the rice plant's natural production of aroma compounds, of which 2-acetyl-1-pyrroline is the most salient. A rapid loss of aromatic intensity leads many Southeast Asians and connoisseurs to prefer each year's freshly harvested "new crop" of jasmine rice. Jasmine rice is a variety of Oryza sativa.
Ambemohar is a fragrant rice variant grown in the foothills of the Western ghats region of the state of Maharashtra in India.
Domsiah is an Iranian variety of rice. It is a long-grain rice, with a black spot on one end, which gives it the name, which is Persian meaning "black end". It is cultivated mainly in the Gilan province of Iran.
Broken rice is fragments of rice grains, broken in the field, during drying, during transport, or during milling. Mechanical separators are used to separate the broken grains from the whole grains and sort them by size.
In the cuisine of Sikkim, in northeastern India, rice is a staple food, and fermented foods traditionally constitute a significant portion of the cuisine. Indian cuisine is popular, as Sikkim is the only state of India with an ethnic Indian Gorkha majority. Many restaurants in Sikkim serve various types of Nepalese cuisine, such as the Limbu, Newa and Thakali cuisines. Tibetan cuisine has also influenced Sikkimese cuisine. The combination of various cuisines has resulted in one specific cuisine.
Oryza glaberrima, commonly known as African rice, is one of the two domesticated rice species. It was first domesticated and grown in West Africa around 3,000 years ago. In agriculture, it has largely been replaced by higher-yielding Asian rice, and the number of varieties grown is declining. It still persists, making up an estimated 20% of rice grown in West Africa. It is now rarely sold in West African markets, having been replaced by Asian strains.
Japonica rice, sometimes called sinica rice, is one of the two major domestic types of Asian rice varieties. Japonica rice is extensively cultivated and consumed in East Asia, whereas in most other regions indica rice is the dominant type of rice. Japonica rice originated from Central China, where it was first domesticated along the Yangtze River basin approximately 9,500 to 6,000 years ago.
Rice production in China is the amount of rice planted, grown, and harvested for consumption in the mainland of China.
Perennial rice are varieties of long-lived rice that are capable of regrowing season after season without reseeding; they are being developed by plant geneticists at several institutions. Although these varieties are genetically distinct and will be adapted for different climates and cropping systems, their lifespan is so different from other kinds of rice that they are collectively called perennial rice. Perennial rice—like many other perennial plants—can spread by horizontal stems below or just above the surface of the soil but they also reproduce sexually by producing flowers, pollen and seeds. As with any other grain crop, it is the seeds that are harvested and eaten by humans.
Kalanamak is a scented rice of Nepal and India. Its name means black husk. This variety has been in cultivation since the original Buddhist period. It is popular in Himalayan Tarai of Nepal i.e., Kapilvastu, and eastern Uttar Pradesh, where it is known as the scented black pearl. It was featured in the book Speciality rices of the world by Food and Agriculture Organization of the United Nations.
Gandhakasala rice is a variety of rice cultivated by the farmers in Wayanad District in Kerala. This is a scented variety of rice grown mostly by the members of the tribal communities of in Panamaram, Sultan Bathery, and Mananthavady areas in Wayanad. As of 2010, gandhkasala is cultivated in an area of 327 hectares and jeerakasala in 22 hectares.
Ofada rice is a Yoruba dish. It is the name of an indigenous rice from a small community called Ofada, located in the Obafemi Owode Local Government Area of Ogun State. It is not exclusively grown in the community, but it is an indigenous rice grown in southwest Nigeria but named after the Ofada community. It is used in making a variety of dishes. Ofada rice are mostly blends, and some of the rice varieties in the blends are not indigenous to Africa; however, they usually also contain African rice. It is grown almost exclusively in Ogun State, a state in southwestern Nigeria. Ofada rice is grown on free-draining soil where the water table is permanently below the root of the plant.
Paw san hmwe is a high-grade variety of aromatic rice grown in Myanmar. Paw hsan hmwe is known for its good cooking quality, fragrant aroma, texture, good milling recovery, and substantial grain elongation during the cooking process. The medium-length grains of this rice variety can elongate up to three times in length while cooking. Paw hsan hmwe has intermediate amylose content, higher than jasmine rice, contributing to its hardness quality in line with Burmese consumer preferences. Myanmar's Paw San rice is one of the world's most recognized high quality rice, it was awarded the world's best rice at the Rice Trader's World Rice Conference in 2011. Paw San rice has a similar aroma, grain quality and eating quality to the reputable aromatic rice varieties of the world, namely Basmati of India and Pakistan and Jasmine of Thailand. It has a strong aroma similar to Jasmine rice and the fluffiness and elongation-up to 3 times after cooking of Basmati rice. Despite these qualities, Paw San rice has not made it to the export market due to its low yield. As well, a high domestic demand leaves little to export. The low yield has been an important barrier to its wider adoption; only about 6% of the area under rice cultivation was planted to Paw San in 2013. In order to meet export target and increase export value, Myanmar would need to promote the wider adoption of Paw San rice. To support the campaign for adoption, the county also would need to develop the infrastructure and the technology to increase productivity.
The history of rice cultivation is an interdisciplinary subject that studies archaeological and documentary evidence to explain how rice was first domesticated and cultivated by humans, the spread of cultivation to different regions of the planet, and the technological changes that have impacted cultivation over time.
