Wheat
Wheat is a grass widely cultivated for its seed, a cereal grain that is a worldwide staple food. The many species of wheat together make up the genus ''Triticum'' ; the most widely grown is common wheat (''T. aestivum''). The archaeological record suggests that wheat was first cultivated in the regions of the Fertile Crescent around 9600 BCE. Botanically, the wheat kernel is a type of fruit called a caryopsis. Wheat is grown on more land area than any other food crop (, 2014). World trade in wheat is greater than for all other crops combined. In 2020, world production of wheat was , making it the second most-produced cereal after maize. Since 1960, world production of wheat and other grain crops has tripled and is expected to grow further through the middle of the 21st century. Global demand for wheat is increasing due to the unique viscoelastic and adhesive properties of gluten proteins, which facilitate the production of processed foods, whose consumption is ...

Taxonomy Of Wheat
During 10,000 years of cultivation, numerous forms of wheat, many of them hybrids, have developed under a combination of artificial and natural selection. This diversity has led to much confusion in the naming of wheats. This article explains how genetic and morphological characteristics of wheat influence its classification, and gives the most common botanical names of wheat in current use (see ). Information on the cultivation and uses of wheat is at the main wheat page. ''Aegilops'' and ''Triticum'' The genus ''Triticum'' includes the wild and domesticated species usually thought of as wheat. In the 1950s growing awareness of the genetic similarity of the wild goatgrasses ('' Aegilops'') led botanists such as Bowden to amalgamate ''Aegilops'' and ''Triticum'' as one genus, ''Triticum''. This approach is still followed by some (mainly geneticists), but has not been widely adopted by taxonomists. ''Aegilops'' is morphologically highly distinct from ''Triticum'', with rounded r ...

Triticum Compactum
''Triticum compactum'' or club wheat is a species of wheat adapted to low-humidity growing conditions. ''T. compactum'' is similar enough to common wheat (''T. aestivum'') that it is often considered a subspecies, ''T. aestivum compactum''. It can be distinguished by its more compact ear due to shorter rachis segments, giving it its common name. In the United States of America, nearly all ''T. compactum'' is grown in dry areas of the Pacific Northwest. ''T. compactum'' is a hexaploid with 21 chromosomes. ''T. compactum'', like other club wheats, has been selectively bred for its lower protein content. Due to the process of selective breeding ''T. compactum'' has fewer HMW-glutenin genes than other species of wheat. Flour made from ''T. compactum'' is thus better suited for the production of cookies. ''T. compactum'' like other bread wheats have never been observed to grow in the wild.Harold J. E. Peake.

Emmer
Emmer wheat or hulled wheat is a type of awned wheat. Emmer is a tetraploid (4''n'' = 4''x'' = 28 chromosomes). The domesticated types are ''Triticum turgidum'' subsp. ''dicoccum'' and ''Triticum turgidum ''conv.'' durum''. The wild plant is called ''Triticum turgidum'' subsp. ''dicoccoides''. The principal difference between the wild and the domestic is that the ripened seed head of the wild plant shatters and scatters the seed onto the ground, while in the domesticated emmer the seed head remains intact, thus making it easier for humans to harvest the grain. Along with einkorn wheat, emmer was one of the first crops domesticated in the Near East. It was widely cultivated in the ancient world, but is now a relict crop in mountainous regions of Europe and Asia. Emmer is considered a type of ''farro'' food especially in Italy. Taxonomy Strong similarities in morphology and genetics show that wild emmer (''Triticum dicoccoides'' Koern.) is the wild ancestor and a crop wi ...

Triticum Spelta
Spelt (''Triticum spelta''), also known as dinkel wheat or hulled wheat, is a species of wheat that has been cultivated since approximately 5000 BC. Spelt was an important staple food in parts of Europe from the Bronze Age to medieval times. Now it survives as a relict crop in Central Europe and northern Spain, and it has found a new market as a health food. Spelt is sometimes considered a subspecies of the closely related species common wheat (''Triticum aestivum''), in which case its botanical name is considered to be ''Triticum aestivum'' subsp. ''spelta''. Like common wheat, it is a hexaploid wheat, which means it has six sets of chromosomes. Evolution Spelt has a complex history. It is a wheat species known from genetic evidence to have originated as a naturally occurring hybrid of a domesticated tetraploid wheat such as emmer wheat and the wild goat-grass ''Aegilops tauschii''. Genetic evidence shows that spelt wheat can also arise as the result of the hybridisa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Triticum Durum
Durum wheat (), also called pasta wheat or macaroni wheat (''Triticum durum'' or ''Triticum turgidum'' subsp. ''durum''), is a tetraploid species of wheat. It is the second most cultivated species of wheat after common wheat, although it represents only 5% to 8% of global wheat production. It was developed by artificial selection of the domesticated emmer wheat strains formerly grown in Central Europe and the Near East around 7000 BC, which developed a naked, free-threshing form. Like emmer, durum wheat is awned (with bristles). It is the predominant wheat that grows in the Middle East. ''Durum'' in Latin means "hard", and the species is the hardest of all wheats. This refers to the resistance of the grain to milling, in particular of the starchy endosperm, implying dough made from its flour is weak or "soft". This makes durum favorable for semolina and pasta and less practical for flour, which requires more work than with hexaploid wheats like common bread wheats. Despite ...

Cereal
A cereal is any grass cultivated for the edible components of its grain (botanically, a type of fruit called a caryopsis), composed of the endosperm, germ, and bran. Cereal grain crops are grown in greater quantities and provide more food energy worldwide than any other type of crop and are therefore staple crops. They include wheat, rye, oats, and barley. Edible grains from other plant families, such as buckwheat, quinoa and chia, are referred to as pseudocereals. In their unprocessed whole grain form, cereals are a rich source of vitamins, minerals, carbohydrates, fats, oils, and protein. When processed by the removal of the bran and germ the remaining endosperm is mostly carbohydrate. In some developing countries, grain in the form of rice, wheat, millet, or maize constitutes a majority of daily sustenance. In developed countries, cereal consumption is moderate and varied but still substantial, primarily in the form of refined and processed grains. Because of ...

Triticum Boeoticum
Einkorn wheat (from German ''Einkorn'', literally "single grain") can refer either to a wild species of wheat (''Triticum'') or to its domesticated form. The wild form is '' T. boeoticum'' (syn. ''T. m.'' ssp. ''boeoticum''), the domesticated form is '' T. monococcum'' (syn. ''T. m.'' ssp. ''boeoticum''). Einkorn is a diploid species (2''n'' = 14 chromosomes) of hulled wheat, with tough glumes ('husks') that tightly enclose the grains. The cultivated form is similar to the wild, except that the ear stays intact when ripe and the seeds are larger. The domestic form is known as "petit épeautre" in French, "Einkorn" in German, "einkorn" or "littlespelt" in English, "piccolo farro" in Italian and "escanda menor" in Spanish. The name refers to the fact that each spikelet contains only one grain. Einkorn wheat was one of the first plants to be domesticated and cultivated. The earliest clear evidence of the domestication of einkorn dates from 10,600 to 9,900 years before present ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
