Muslims constitute 13% of the population. 3% of the population are followers of
352-438: A combination of artificial and natural selection . This complexity and diversity of status has led to much confusion in the naming of wheats. Hexaploid species (6N) Tetraploid species (4N) Diploid species (2N) The wild species of wheat, along with the domesticated varieties einkorn , emmer and spelt , have hulls. This more primitive morphology (in evolutionary terms) consists of toughened glumes that tightly enclose
440-535: A decline in climate resilience of wheat has been observed. Hunter-gatherers in West Asia harvested wild wheats for thousands of years before they were domesticated , perhaps as early as 21,000 BC, but they formed a minor component of their diets. In this phase of pre-domestication cultivation, early cultivars were spread around the region and slowly developed the traits that came to characterise their domesticated forms. Repeated harvesting and sowing of
528-409: A good crop of grain. The farmer may intervene while the crop is growing to add fertilizer , water by irrigation , or pesticides such as herbicides to kill broad-leaved weeds or insecticides to kill insect pests. The farmer may assess soil minerals, soil water, weed growth, or the arrival of pests to decide timely and cost-effective corrective actions, and crop ripeness and water content to select
616-470: A less reliable method based on grain size. Einkorn and emmer are considered two of the founder crops cultivated by the first farming societies in Neolithic West Asia. These communities also cultivated naked wheats ( T. aestivum and T. durum ) and a now-extinct domesticated form of Zanduri wheat ( T. timopheevii ), as well as a wide variety of other cereal and non-cereal crops. Wheat
704-681: A low quality for human nutrition, according to the DIAAS protein quality evaluation method. Though they contain adequate amounts of the other essential amino acids, at least for adults, wheat proteins are deficient in the essential amino acid lysine . Because the proteins present in the wheat endosperm (gluten proteins) are particularly poor in lysine, white flours are more deficient in lysine compared with whole grains. Significant efforts in plant breeding are made to develop lysine-rich wheat varieties, without success, as of 2017 . Supplementation with proteins from other food sources (mainly legumes )
792-450: A major contribution to the nutritional welfare of the poor. Some wheat species are diploid , with two sets of chromosomes , but many are stable polyploids , with four sets of chromosomes ( tetraploid ) or six ( hexaploid ). Einkorn wheat ( Triticum monococcum ) is diploid (AA, two complements of seven chromosomes, 2n=14). Most tetraploid wheats (e.g. emmer and durum wheat) are derived from wild emmer , T. dicoccoides . Wild emmer
880-475: A major contributor to increased grain output. More widely over the last 40 years, a massive increase in fertilizer use together with the increased availability of semi-dwarf varieties in developing countries, has greatly increased yields per hectare. In developing countries, use of (mainly nitrogenous) fertilizer increased 25-fold in this period. However, farming systems rely on much more than fertilizer and breeding to improve productivity. A good illustration of this
968-874: A major role in Pugachev's Rebellion (1773–1774), the largest peasant revolt in Russian history. During the Russian Civil War , the region was heavily affected by the Russian famine of 1921–1922 . During World War II in 1941, the command and staff of the newly formed Polish Anders' Army was based in Buzuluk , and in 1942, the First Czechoslovak Independent Field Battalion was based there. Both formations afterwards fought against Nazi Germany . On 26 May 2024,

Four of those territories have a second official language in addition to Russian: Buryat (in two of the merged territories), Komi-Permian , Koryak . This is an exception: all the other official languages of Russia (other than Russian) are set by the Constitutions of its constituent Republics ( Mordovia , Chechnya , Dagestan etc.). The status of the "administrative-territorial regions with special status" has been

Yields of pure wheat per unit area increased as methods of crop rotation were applied to land that had long been in cultivation, and the use of fertilizers became widespread. Improved agricultural husbandry has more recently included pervasive automation , starting with
1496-418: A wheat plant is known as the flag leaf. It is denser and has a higher photosynthetic rate than other leaves, to supply carbohydrate to the developing ear. In temperate countries the flag leaf, along with the second and third highest leaf on the plant, supply the majority of carbohydrate in the grain and their condition is paramount to yield formation. Wheat is unusual among plants in having more stomata on
1584-506: A year's supply. Wheat grain was stored after threshing , with the chaff removed. It was then processed into flour using ground stone mortars . Bread made from ground einkorn and the tubers of a form of club rush ( Bolboschoenus glaucus ) was made as early as 12,400 BC. At Çatalhöyük ( c. 7100–6000 BC ), both wholegrain wheat and flour was used to prepare bread, porridge and gruel . Apart from food, wheat may also have been important to Neolithic societies as

There are many wheat diseases, mainly caused by fungi, bacteria, and viruses . Plant breeding to develop new disease-resistant varieties, and sound crop management practices are important for preventing disease. Fungicides, used to prevent
2024-459: Is also important to identify periods of higher risk from the climate. Farmers benefit from knowing when the 'flag leaf' (last leaf) appears, as this leaf represents about 75% of photosynthesis reactions during the grain filling period, and so should be preserved from disease or insect attacks to ensure a good yield. Several systems exist to identify crop stages, with the Feekes and Zadoks scales being

Chukotka is one of the richest subjects of Russia (with a Gross Regional Product [GRP] per capita equivalent to that of Australia) and therefore does not fit in the pattern of merging a subject to benefit from the economic dynamism of the neighbour. In 1992, Ingushetia separated from Chechnya , both to stay away from
2288-418: Is greater than for all other crops combined. 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 increasing as a result of the worldwide industrialization process and westernization of diets . Wheat became a central agriculture endeavor in the worldwide British Empire in
2376-473: Is itself the result of a hybridization between two diploid wild grasses, T. urartu and a wild goatgrass such as Ae. speltoides . The hybridization that formed wild emmer (AABB, four complements of seven chromosomes in two groups, 4n=28) occurred in the wild, long before domestication, and was driven by natural selection . Hexaploid wheats evolved in farmers' fields as wild emmer hybridized with another goatgrass, Ae. squarrosa or Ae. tauschii , to make
2464-629: Is likely to be prioritised in drought-adapted crops, while stem non-structural carbohydrate is prioritised in varieties developed for countries where disease is a bigger issue. Depending on variety, wheat may be awned or not awned. Producing awns incurs a cost in grain number, but wheat awns photosynthesise more efficiently than their leaves with regards to water usage, so awns are much more frequent in varieties of wheat grown in hot drought-prone countries than those generally seen in temperate countries. For this reason, awned varieties could become more widely grown due to climate change . In Europe, however,
2552-458: Is more diverse, with domesticated varieties falling into two major groups: hulled or non-shattering, in which threshing separates the whole spikelet ; and free-threshing, where the individual grains are separated. Both varieties probably existed in prehistory, but over time free-threshing cultivars became more common. Wild emmer was first cultivated in the southern Levant , as early as 9600 BC. Genetic studies have found that, like einkorn, it
2640-399: Is normally planted after tilling the soil by ploughing and then harrowing to kill weeds and create an even surface. The seeds are then scattered on the surface, or drilled into the soil in rows. Winter wheat lies dormant during a winter freeze. It needs to develop to a height of 10 to 15 cm before the cold intervenes, so as to be able to survive the winter; it requires a period with
2728-511: Is not the same as a wheat allergy . Other diseases triggered by eating wheat are non-coeliac gluten sensitivity (estimated to affect 0.5% to 13% of the general population ), gluten ataxia , and dermatitis herpetiformis . Certain short-chain carbohydrates present in wheat, known as FODMAPs (mainly fructose polymers ), may be the cause of non-coeliac gluten sensitivity. As of 2019 , reviews have concluded that FODMAPs only explain certain gastrointestinal symptoms, such as bloating , but not

Raw red winter wheat is 13% water, 71% carbohydrates including 12% dietary fiber , 13% protein , and 2% fat (table). Some 75–80% of the protein content is as gluten . In a reference amount of 100 grams (3.5 oz), wheat provides 1,368 kilojoules (327 kilocalories) of food energy and
2904-501: The Constitution of Russia from Russian to English uses the term "constituent entities of the Russian Federation". For example, Article 5 reads: "The Russian Federation shall consist of republics , krais , oblasts , cities of federal significance , an autonomous oblast , and autonomous okrugs , which shall have equal rights as constituent entities of the Russian Federation."

In domesticated wheat, grains are larger, and the seeds (inside the spikelets ) remain attached to the ear by a toughened rachis during harvesting. In wild strains, a more fragile rachis allows the ear to shatter easily, dispersing the spikelets. Selection for larger grains and non-shattering heads by farmers might not have been deliberately intended, but simply have occurred because these traits made gathering

6336-517: The second largest producer of wheat in the world. In the 19th century the American wheat frontier moved rapidly westward. By the 1880s 70% of American exports went to British ports. The first successful grain elevator was built in Buffalo in 1842. The cost of transport fell rapidly. In 1869 it cost 37 cents to transport a bushel of wheat from Chicago to Liverpool . In 1905 it was 10 cents. In
6424-513: The seeds easier; nevertheless such 'incidental' selection was an important part of crop domestication . As the traits that improve wheat as a food source involve the loss of the plant's natural seed dispersal mechanisms, highly domesticated strains of wheat cannot survive in the wild. Wild einkorn wheat ( T. monococcum subsp. boeoticum ) grows across Southwest Asia in open parkland and steppe environments. It comprises three distinct races , only one of which, native to Southeast Anatolia ,
6512-417: The stem, one above each joint. At the top of the stem is the flower head, containing some 20 to 100 flowers. Each flower contains both male and female parts. The flowers are wind-pollinated , with over 99% of pollination events being self-pollinations and the rest cross-pollinations . The flower is housed in a pair of small leaflike glumes . The two (male) stamens and (female) stigmas protrude outside
6600-405: The temperature at or near freezing, its dormancy then being broken by the thaw or rise in temperature. Spring wheat does not undergo dormancy. Wheat requires a deep soil , preferably a loam with organic matter, and available minerals including soil nitrogen, phosphorus, and potassium. An acid and peaty soil is not suitable. Wheat needs some 30 to 38 cm of rain in the growing season to form
6688-409: The term "subjects of the Russian Federation". Tom Fennell, a translator, told the 2008 American Translators Association conference that "constituent entity of the Russian Federation" is a better translation than "subject". This was supported by Tamara Nekrasova, Head of Translation Department at Goltsblat BLP , who said in a 2011 presentation at a translators conference that " constituent entity of
6776-514: The text of the 1978 Constitution of the Russian SFSR . The current Constitution of Russia, adopted by federal referendum on 12 December 1993, came into force on 25 December 1993 and abolished the model of the Soviet system of government introduced in 1918 by Vladimir Lenin and based on the right to secede from the country and on unlimited sovereignty of federal subjects (in practice secession
6864-407: The upper ( adaxial ) side of the leaf, than on the under ( abaxial ) side. It has been theorised that this might be an effect of it having been domesticated and cultivated longer than any other plant. Winter wheat generally produces up to 15 leaves per shoot and spring wheat up to 9 and winter crops may have up to 35 tillers (shoots) per plant (depending on cultivar). Wheat roots are among
6952-614: The use of threshing machines , and progressing to large and costly machines like the combine harvester which greatly increased productivity. At the same time, better varieties such as Norin 10 wheat , developed in Japan in the 1930s, or the dwarf wheat developed by Norman Borlaug in the Green Revolution , greatly increased yields. In addition to gaps in farming system technology and knowledge, some large wheat grain-producing countries have significant losses after harvest at
7040-542: The use of the oven and developed baking into one of the first large-scale food production industries." By 4000 BC, wheat had reached the British Isles and Scandinavia . Wheat likely appeared in China 's lower Yellow River around 2600 BC. The oldest evidence for hexaploid wheat has been confirmed through DNA analysis of wheat seeds, dating to around 6400–6200 BC, recovered from Çatalhöyük . As of 2023,
7128-446: The usefulness of gluten to the food industry. Wheat is an important source of carbohydrates . Globally, it is the leading source of vegetable proteins in human food, having a protein content of about 13%, which is relatively high compared to other major cereals but relatively low in protein quality (supplying essential amino acids ). When eaten as the whole grain , wheat is a source of multiple nutrients and dietary fiber . In
7216-417: Was 771 million tonnes (850 million short tons), 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
7304-486: Was 808.4 million tonnes, led by China, India, and Russia which collectively provided 43.22% of the world total. As of 2019 , the largest exporters were Russia (32 million tonnes), United States (27), Canada (23) and France (20), while the largest importers were Indonesia (11 million tonnes), Egypt (10.4) and Turkey (10.0). In 2021, wheat was grown on 220.7 million hectares or 545 million acres worldwide, more than any other food crop. World trade in wheat
7392-462: Was domesticated in southeastern Anatolia, but only once. The earliest secure archaeological evidence for domestic emmer comes from Çayönü, c. 8300–7600 BC , where distinctive scars on the spikelets indicated that they came from a hulled domestic variety. Slightly earlier finds have been reported from Tell Aswad in Syria, c. 8500–8200 BC , but these were identified using
7480-429: Was domesticated. The main feature that distinguishes domestic einkorn from wild is that its ears do not shatter without pressure, making it dependent on humans for dispersal and reproduction. It also tends to have wider grains. Wild einkorn was collected at sites such as Tell Abu Hureyra ( c. 10,700–9000 BC ) and Mureybet ( c. 9800–9300 BC ), but the earliest archaeological evidence for
7568-601: Was historically a high status food, but during the nineteenth century it became in Britain an item of mass consumption, displacing oats , barley and rye from diets in the North of the country. It became "a sign of a high degree of culture". After 1860, the enormous expansion of wheat production in the United States flooded the world market, lowering prices by 40%, and (along with the expansion of potato growing) made
7656-491: Was never allowed), which conflicts with the country's integrity and federal laws. The new constitution eliminated a number of legal conflicts, reserved the rights of the regions, introduced local self-government and did not grant the Soviet-era right to secede from the country. In the late 1990s and early 2000s the political system became de jure closer to other modern federal states with a republican form of government . In
7744-456: Was relatively uncommon for the first thousand years of the Neolithic (when barley predominated), but became a staple after around 8500 BC. Early wheat cultivation did not demand much labour. Initially, farmers took advantage of wheat's ability to establish itself in annual grasslands by enclosing fields against grazing animals and re-sowing stands after they had been harvested, without
