[138] Plant breeding to develop new disease-resistant varieties, and sound crop management practices are important for preventing disease. [126] The largest importers of wheat in 2016 were, in order of imported quantities: Indonesia (10.5 million tonnes), Egypt (8.7 million tonnes), Algeria (8.2 million tonnes), Italy (7.7 million tonnes) and Spain (7.0 million tonnes). The major diseases in temperate environments include the following, arranged in a rough order of their significance from cooler to warmer climates: eyespot, Stagonospora nodorum blotch (also known as glume blotch), yellow or stripe rust, powdery mildew, Septoria tritici blotch (sometimes known as leaf blotch), brown or leaf rust, Fusarium head blight, tan spot and stem rust. [citation needed], The oldest evidence for hexaploid wheat has been confirmed through DNA analysis of wheat seeds, dating to around 6400-6200 BCE, recovered from Çatalhöyük. Wheat has come to be a firm favourite grain because of the diversity it provides in culinary applications. As of 2019, reviews have concluded that FODMAPs only explain certain gastrointestinal symptoms, such as bloating, but not the extra-digestive symptoms that people with non-coeliac gluten sensitivity may develop, such as neurological disorders, fibromyalgia, psychological disturbances, and dermatitis. In particular, spring fertilizers, herbicides, fungicides, and growth regulators are typically applied only at specific stages of plant development. [104] The only known effective treatment is a strict lifelong gluten-free diet. [69] On 29 November 2012, an essentially complete gene set of bread wheat was published. The protein content in wheat can vary, and certain strains of wheat are better for making bread while others are more appropriate for pasta, cakes, cookies, cereals and other dietary staples. [115] Some information providers, following CBOT practice, quote the wheat market in per ton denomination. The unknown grass has never been identified among non extinct wild grasses, but the closest living relative is Aegilops speltoides. Of these about 1,000 are commercially significant. speltoides. Wheat is the most important cereal grain in world commerce. 207–21, "AFLP analysis of a collection of tetraploid wheats indicates the origin of emmer and hard wheat domestication in southeast Turkey", "Britons may have imported wheat long before farming it", "Ancient genomes indicate population replacement in Early Neolithic Britain", "Ancient DNA from 8400 Year-Old Çatalhöyük Wheat: Implications for the Origin of Neolithic Agricultur", "The science in detail â€“ Wheats DNA â€“ Research â€“ Archaeology â€“ The University of Sheffield", Fertilising for High Yield and Quality - Cereals, "Shifts in stomatal traits following the domestication of plant species", "Labeling of Fructans in Winter Wheat Stems", "Wheat genotypic variation in dynamic fluxes of WSC components in different stem segments under drought during grain filling", "Awns reduce grain number to increase grain size and harvestable yield in irrigated and rainfed spring wheat", "Decline in climate resilience of European wheat", Guinness World Records - Highest Wheat Yield, Farmers Weekly - Lincs grower scoops top wheat and rapeseed yield awards, Agricultural and Horticultural Development Board - 2018 GB Harvest Progress Results, "Plant genetic resources: What can they contribute toward increased crop productivity? In cooked form, the nutrition value for each staple depends on the cooking method (for example: baking, boiling, steaming, frying, etc.). Common or bread wheat Triticum aestivum accounts for some 95 percent of all the consumed wheat in the world today; the other five percent is made up of durum or hard wheat T. turgidum ssp.

Producing awns incurs a cost in grain number,[42] but wheat awns photosynthesise more water-use-efficiently than their leaves,[43] so awns are much more frequent in varieties of wheat grown in hot drought-prone countries than those generally seen in temperate countries. [70] Random shotgun libraries of total DNA and cDNA from the T. aestivum cv. [84][104] Coeliac disease affects about 1% of the general population in developed countries. The wheat has turned a golden yellow colour indicating that it is ready for harvest. [129][130][131] The central tenet is that a point is reached, the "peak", beyond which agricultural production plateaus and does not grow any further,[132] and may even go into permanent decline. Cultivation and repeated harvesting and sowing of the grains of wild grasses led to the creation of domestic strains, as mutant forms ('sports') of wheat were preferentially chosen by farmers. [93], Wheat is grown on more than 218,000,000 hectares (540,000,000 acres). ", Jon Markman, March 6, 2008 at, Andrew McKillop (2006-12-13). For example, pollen formation from the mother cell, and the stages between anthesis and maturity, are susceptible to high temperatures, and this adverse effect is made worse by water stress. [123], In the Punjab region of the Indian subcontinent, as well as North China, irrigation has been a major contributor to increased grain output. Peak wheat is the concept that agricultural production, due to its high use of water and energy inputs,[128] is subject to the same profile as oil and other fossil fuel production. With the exception of Iraq ed-Dubb, the earliest carbon-14 dated remains of domesticated emmer wheat were found in the earliest levels of Tell Aswad, in the Damascus basin, near Mount Hermon in Syria. Generally speaking, the nutritional profiles of the grains do not differ much beyond the protein. The nutritional composition of the wheat grain varies somewhat with differences in climate and soil. [49][50], Wild grasses in the genus Triticum and related genera, and grasses such as rye have been a source of many disease-resistance traits for cultivated wheat breeding since the 1930s. There are many wheat diseases, mainly caused by fungi, bacteria, and viruses. Q = Quality of Protein in terms of completeness without adjusting for digestability. The wheat plant has long slender leaves and stems that are hollow in most varieties. In recent years, low international wheat prices have often encouraged farmers in the United States to change to more profitable crops. The majority of biomass production post- flowering is allocated to the grain. In domesticated wheat, grains are larger, and the seeds (inside the spikelets) remain attached to the ear by a toughened rachis during harvesting. [74], Einkorn wheat (T. monococcum) is diploid (AA, two complements of seven chromosomes, 2n=14).[4]. WHEAT EXPORTS Year Quantity (Lakh Tones) Value (Crore rupees) 1996-97 18.49115 1206.48600 1999-2000 0.01040 1.09070 2002-2003 19.45540 941.35880 14. Boza, a traditional fermented drink in eastern Europe and the Middle East that is made from wheat, millet, or bulgur and topped with cinnamon and roasted chickpeas. Several crops may be … There are many species of this particular genus that is used for cultivation such as Triticum sativum, Triticum polonicum, Triticum monococcum, etc. [8] Ireland wheat farms were the most productive in 2014, with a nationwide average of 10.0 tonnes per hectare, followed by the Netherlands (9.2), and Germany, New Zealand and the United Kingdom (each with 8.6). This may explain why there is an increase of inflammation in people with preexisting diseases upon ingestion of ATIs-containing grains. Estimates of the amount of wheat production lost owing to plant diseases vary between 10–25% in Missouri. 70% of the Indian population depends on agriculture for food and money. Young wheat crop in a field near Solapur, Maharashtra, India, A combine harvester threshes the wheat, crushes the chaff, then blows chaff across the field. At present, it is cultivated in more land area than all major commercial crops such as rice, maize, potatoes and so on. [75] The hybridization that formed wild emmer (AABB) occurred in the wild, long before domestication,[74] and was driven by natural selection. Ring in the new year with a Britannica Membership. This symptoms is known as a "deadheart" symptom. Wheat is also the best grain for bread making. Wheat is one of the oldest and most important of the cereal crops. Both barley and oats are susceptible too, but to a much lesser degree. Encyclopaedia Britannica's editors oversee subject areas in which they have extensive knowledge, whether from years of experience gained by working on that content or via study for an advanced degree.... Time-lapse video showing wheat germination and growth; the underground sequence was filmed over five days and the appearance of leaves over six days. The same field later in the same year just before harvest. [44], In traditional agricultural systems wheat populations often consist of landraces, informal farmer-maintained populations that often maintain high levels of morphological diversity. Wheat is a world-wide staple crop providing 20% of our calories and one quarter of our daily protein. "Feldman, Moshe and Kislev, Mordechai E., Israel Journal of Plant Sciences, Volume 55, Number 3–4 / 2007, pp. It is also subject to the vagaries of weather.” According to Peter Johnson of OMAFRA, Fusarium isn’t restricted to corn and wheat. The origins of formal wheat breeding lie in the nineteenth century, when single line varieties were created through selection of seed from a single plant noted to have desired properties. Alluvial Soils. "Peak Natural Gas is On the Way". [9] 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 the westernization of the diet. Wheat Varieties . With rice, wheat is the world's most favored staple food. Wheat (species of Triticum) is a cereal grain. [45] Commercial hybrid wheat seed has been produced using chemical hybridizing agents, plant growth regulators that selectively interfere with pollen development, or naturally occurring cytoplasmic male sterility systems. Wheats grown in dry climates are generally hard types, having protein content of 11–15 percent and strong gluten (elastic protein). [29], From Asia, wheat continued to spread across Europe. Parts of the plant Wheat is an annual grass made up of roots, stems with tillers, leaves, inflorescence and seeds. Genes for the 'dwarfing' trait, first used by Japanese wheat breeders to produce short-stalked wheat, have had a huge effect on wheat yields worldwide, and were major factors in the success of the Green Revolution in Mexico and Asia, an initiative led by Norman Borlaug. However, Triticum sativum is the most cultivated wheat variety. Great expansion of wheat production occurred as new arable land was farmed in the Americas and Australia in the 19th and 20th centuries. Heavy soil with open structure which can retain the monsoon rainfall for longer period is ideal for dry wheat crop. [115] In that study, farm wheat yields averaged 41.7 bushels per acre (2.2435 metric ton/hectare), and typical total wheat production value was $31,900 per farm, with total farm production value (including other crops) of $173,681 per farm, plus $17,402 in government payments. These must be sprouted, or prepared and cooked as appropriate for human consumption. [109] A 2017 study in mice demonstrated that ATIs exacerbate preexisting inflammation and might also worsen it at extraintestinal sites. [117], Average wheat yields, measured in tonnes per hectare in 2014. Diversity is king and has well known benefits. [74] These have three sets of paired chromosomes, three times as many as in diploid wheat. Optimal crop management requires that the farmer have a detailed understanding of each stage of development in the growing plants. Agcapita Farmland Investment Partnership - Peak oil v. Peak Wheat, July 1, 2008, Credit Suisse First Boston, Higher Agricultural Prices: Opportunities and Risks, November 2007, Food Production May Have to Double by 2030 - Western Spectator, Learn how and when to remove this template message, International wheat production statistics, "Crops/World Total/Wheat/Area Harvested/2014 (pick list)", "World food situation: FAO cereal supply and demand brief", "Crops/World Total/Wheat/Production Quantity/2014 (pick list)", "Food security: The challenge of feeding 9 billion people", "Review: The contribution of wheat to human diet and health", Community Research and Development Information Service, "Genetic markers signal increased crop productivity potential", "The Oslo definitions for coeliac disease and related terms", "μCT trait analysis reveals morphometric differences between domesticated temperate small grain cereals and their wild relatives". [61] However, a 2020 study that grew and analyzed 60 wheat cultivars from between 1891 and 2010 found no changes in albumin/globulin and gluten contents over time. Advances in wheat production during the 20th century included improvements through the introduction of new varieties and strains; careful selection by farmers and seedsmen, as well as by scientists; and crossbreeding to combine desirable characteristics. [7][8] 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. These have mostly been solved, so that in the 20th century millions of acres of triticale are being grown worldwide. Mike Abram for Farmers' Weekly. Better seed storage and germination ability (and hence a smaller requirement to retain harvested crop for next year's seed) is another 20th-century technological innovation. [6][95][96], Consumed worldwide by billions of people, wheat is a significant food for human nutrition, particularly in the least developed countries where wheat products are primary foods. Wheat is grown on more land area than any other food crop (220.4 million hectares, 2014). Roots The wheat plant has two types of roots: seminal and adventitious. The Many Uses of Wheat . [119], In the 20th century, global wheat output expanded by about 5-fold, but until about 1955 most of this reflected increases in wheat crop area, with lesser (about 20%) increases in crop yields per unit area. [72], Then in 2020 some of the same researchers produced 15 genome sequences from various locations and varieties around the world[65][66][67] - the most complete and detailed so far[65][66][67] - along with examples of their own use of the sequences to localize particular insect and disease resistance factors. It is responsible for the development of the great bread-wheat civilizations from Mesopotamia to India, and China to Egypt, Greece and Rome, and then to our region. [20] With the anomalous exception of two grains from Iraq ed-Dubb, the earliest carbon-14 date for einkorn wheat remains at Abu Hureyra is 7800 to 7500 years BCE. [76], In free-threshing (or naked) forms, such as durum wheat and common wheat, the glumes are fragile and the rachis tough. Cereal crops such as wheat are semelparous, meaning that they die after their first reproduction. [citation needed], The world record wheat yield is about 17t/ha, reached in New Zealand in 2017. Selections are identified (shown to have the genes responsible for the varietal differences) ten or more generations before release as a variety or cultivar.[45]. When looking at nature, a monoculture only occurs in very rare situations. Since they have higher tendency to retain rainwater for a longer time. Regions – Alluvial soils can be found mainly in the northern Indian delta areas. [118], In 2017, global wheat production was 772 million tonnes, led by China, India, and Russia, collectively providing 41% of the world total. The increased moisture in eastern Nebraska poses sprouting problems that restrict this wheat type to the western half of the state. In Medieval England, farmers saved one-quarter of their wheat harvest as seed for the next crop, leaving only three-quarters for food and feed consumption. [83], In manufacturing wheat products, gluten is valuable to impart viscoelastic functional qualities in dough,[84] enabling the preparation of diverse processed foods such as breads, noodles, and pasta that facilitate wheat consumption. "[62], Stomata (or leaf pores) are involved in both uptake of carbon dioxide gas from the atmosphere and water vapor losses from the leaf due to water transpiration. [85][10], In 100 grams, wheat provides 1,370 kilojoules (327 kilocalories) of food energy and is a rich source (20% or more of the Daily Value, DV) of multiple essential nutrients, such as protein, dietary fiber, manganese, phosphorus and niacin (table). [70] The implications of the research in cereal genetics and breeding includes the examination of genome variation, analysis of population genetics and evolutionary biology, and further studying epigenetic modifications. [6] In 2017, world production of wheat was 772 million tonnes, with a forecast of 2019 production at 766 million tonnes,[7] making it the second most-produced cereal after maize. Such … By alternating grain crops, like wheat, with broadleaf crops such as canola, lupin or a pasture crop like medics we have the opportunity to create diversity on a field. D raw potato with flesh and skin Spelt and Common bread wheat became the favoured types. [47], International wheat breeding is led by CIMMYT in Mexico. Early in the season, many species of birds, including the long-tailed widowbird, and rodents feed upon wheat crops. H raw sorghum Well drained, fertile clay loam soils having moderate water holding capacity are ideal for irrigated wheat. To obtain the grain, further processing, such as milling or pounding, is needed to remove the hulls or husks. [5] World trade in wheat is greater than for all other crops combined. For this reason, awned varieties could become more widely grown due to climate change. This type of wheat has more protein than any other type and is used to make pasta. [63], The gene Sm1 protects against the orange wheat blossom midge.

Wheat bulb fly is a serious pest of wheat crops. White and purple wheats, food barleys, special types of beans, oats for health drinks and even chickpeas are some of the novel crop options being investigated by Agrii. [10] Globally, it is the leading source of vegetable protein in human food, having a protein content of about 13%, which is relatively high compared to other major cereals[12] but relatively low in protein quality for supplying essential amino acids. Significant values are highlighted in light Gray color and bold letters. The name of a wheat species from one information source may not be the name of a wheat species in another. However, other natural forms of wheat exist. It is the backbone of our country. Wheat is the second largest agricultural crop in the world after rice. [35] It has been theorised that this might be an effect of it having been domesticated and cultivated longer than any other plant. Inferior and surplus wheats and various milling by-products are used for livestock feeds. It … [108], The following table shows the nutrient content of wheat and other major staple foods in a raw form.[112]. It is denser and has a higher photosynthetic rate than other leaves, to supply carbohydrate to the developing ear. In the 19th century, efforts were made to hybridize the two do get a crop with the best traits of both. Garnsey Peter. [126], In the rapidly developing countries of Asia and Africa, westernization of diets associated with increasing prosperity is leading to growth in per capita demand for wheat at the expense of the other food staples.

[46] Bread wheat with high grain iron and zinc content was developed through gamma radiation breeding. Neolithic cultures first appear in Britain circa 4000 bc, a millennium after they appeared in adjacent areas of continental Europe. Agriculture plays a very important role in the Indian economy. /* unofficial. About 72 percent of the milled grain is recovered as white flour. In milling, the grain is cracked and then passed through a series of rollers. AREA, PRODUCTION & PRODUCTIVITY 15. Knowledge of stages is also important to identify periods of higher risk from the climate. Within a species, wheat cultivars are further classified by wheat breeders and farmers in terms of: The named classes of wheat in English are more or less the same in Canada as in the US, as broadly the same commercial cash crop strains can be found in both. In tropical areas, spot blotch (also known as Helminthosporium leaf blight) is also important. “And that will depend on different times for different types of crops. Wheat is widely cultivated as a cash crop because it produces a good yield per unit area, grows well in a temperate climate even with a moderately short growing season, and yields a versatile, high-quality flour that is widely used in baking. The milling industry opreates a quality testing system for varieties, to ensure that new varieties meet the quality requirements set by millers. It contains many vitamins and minerals which make it a staple food product. There are many botanical classification systems used for wheat species, discussed in a separate article on wheat taxonomy. Wheat is used as a food plant by the larvae of some Lepidoptera (butterfly and moth) species including the flame, rustic shoulder-knot, setaceous Hebrew character and turnip moth. In fact, over two-thirds of wheat produced globally is used as food. A good illustration of this is Australian wheat growing in the southern winter cropping zone, where, despite low rainfall (300 mm), wheat cropping is successful even with relatively little use of nitrogenous fertilizer. Each year, the weather is the key determinate of wheat supplies. Its 13% protein content is mostly gluten (75-80% of the protein in wheat). And, for growing under rainfed wheat crop, heavy soils having an open structure are best. Different Types of Wheat .
