Triticum
Wheat is a group of wild and domesticated grasses of the genus ''Triticum'' (). They are cultivated for their cereal grains, which are staple foods around the world. Well-known wheat species and hybrids include the most widely grown common wheat (''T. aestivum''), spelt, durum, emmer, einkorn, and Khorasan or Kamut. The archaeological record suggests that wheat was first cultivated in the regions of the Fertile Crescent around 9600 BC. Wheat is grown on a larger area of land than any other food crop ( in 2021). World trade in wheat is greater than that of all other crops combined. In 2021, world wheat production was , making it the second most-produced cereal after maize (known as corn in North America and Australia; wheat is often called corn in countries including Britain). 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 because of t ...

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. Genetic and morphological characteristics of wheat influence its classification; many common and botanical names of wheat are in current use. ''Aegilops'' and ''Triticum'' Similarities and differences 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 rather than keeled glumes. Hybridisation and polyploidy ''Aegilops'' is i ...

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 grown 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, causing dough made from its flour to be weak or "soft". This makes durum favorable for semolina and pasta and less practical for flour, which requires more work than with hexaploid wheats such as common bread wheats. Despite ...

Triticum Turgidum
''Triticum turgidum'' (with its various subspecies being known as ''pasta wheat'', ''macaroni wheat'' and ''durum wheat'') is a species of wheat. It is an annual and grows primarily in temperate areas and is native to countries around the eastern Mediterranean, down to Iran and east to Xinjiang, China. Taxonomy It was first published and described by Carl Linnaeus in his book ''Species Plantarum'' on page 86 in 1753. It is known as ''rivet wheat''. Distribution It is native to the countries of Egypt, Iran, Iraq, Kazakhstan, Kyrgyzstan, Lebanon, North Caucasus (parts of Russia), Syria, Israel, Transcaucasus (or South Caucasus; Armenia, Georgia, and Azerbaijan), Turkey, Turkmenistan, Uzbekistan and Xinjiang, China. It has been introduced into many places, including within Europe (Albania, Austria, Belarus, Bulgaria, Corsica, Crete, Cyprus, Czechia, Denmark, East Aegean Islands, France, Germany, Great Britain, Greece, Hungary, Italy, Madeira, Netherlands, Poland, Portugal, Roman ...

Triticum Dicoccon
Emmer is a hybrid species of wheat, producing edible seeds that have been used as food since ancient times. The domesticated types are ''Triticum turgidum'' subsp. ''dicoccum'' and ''T. t. ''conv.'' durum''. The wild plant is called ''T. t.'' subsp. ''dicoccoides''. The seeds have an awned covering, the sharp spikes helping the seeds to become buried in the ground. The principal difference between the wild and the domestic forms 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 people to harvest the grain. Along with einkorn, 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 one of the three grains called farro in Italy. Etymology Emmer is first attested in 1908 in English as a loanword from German , va ...

Triticum Boeoticum
Einkorn wheat (from German ''Einkorn'', literally "single grain") can refer to either a wild species of wheat (''Triticum'') or a domesticated form of wheat. The wild form is ''T. boeoticum'' (syn. ''T. m.'' subsp. ''boeoticum''), and the domesticated form is ''T. monococcum'' (syn. ''T. m.'' subsp. ''monococcum''). 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 in French, in German, "einkorn" or "littlespelt" in English, in Italian and 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 (8650 BCE to 7950 BCE) from Çayönü and Cafer ...

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 42 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.
