Wheat White Spike Virus
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 the use ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Carl Linnaeus
Carl Linnaeus (23 May 1707 – 10 January 1778), also known after ennoblement in 1761 as Carl von Linné,#Blunt, Blunt (2004), p. 171. was a Swedish biologist and physician who formalised binomial nomenclature, the modern system of naming organisms. He is known as the "father of modern Taxonomy (biology), taxonomy". Many of his writings were in Latin; his name is rendered in Latin as and, after his 1761 ennoblement, as . Linnaeus was the son of a curate and was born in Råshult, in the countryside of Småland, southern Sweden. He received most of his higher education at Uppsala University and began giving lectures in botany there in 1730. He lived abroad between 1735 and 1738, where he studied and also published the first edition of his ' in the Netherlands. He then returned to Sweden where he became professor of medicine and botany at Uppsala. In the 1740s, he was sent on several journeys through Sweden to find and classify plants and animals. In the 1750s and 1760s, he co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Triticum Turanicum
Khorasan wheat or Oriental wheat (''Triticum turgidum'' ssp. ''turanicum'' also called ''Triticum turanicum'') is a tetraploid wheat species. The grain is twice the size of modern-day wheat, and has a rich, nutty flavor. Taxonomy Original botanical identifications were uncertain. The variety is a form of ''Triticum turgidum'' subsp. ''turanicum'' (also known as ''Triticum turanicum''), usually called Greater Khorasan, Khorasan wheat. Khorasan is a province in Iran. Identifications sometimes seen as ''T. polonicum'' are incorrect as the variety, although long-grained, lacks the long glumes of this species. Recent genetic evidence from DNA fingerprinting suggests that the variety is perhaps derived from a natural hybrid between ''Durum, T. durum'' and ''T. polonicum'', which would explain past difficulties in arriving at a certain classification. Origins The grain is named after the Khorasan region—a historical area of ancient Persia which includes Khorasan Province of Iran, p ...

Spelt
Spelt (''Triticum spelta''), also known as dinkel wheat is a species of wheat. It is a relict crop, eaten in Central Europe and northern Spain. It is high in protein and may be considered a health food. Spelt was cultivated from the Neolithic period onward. It was a staple food in parts of Europe from the Bronze Age to the Middle Ages. It is used in baking, and is made into bread, pasta, and beer. It is sometimes considered a subspecies of the closely related common wheat (''T. aestivum''), in which case its botanical name is considered to be ''Triticum aestivum'' subsp. ''spelta''. It is a hexaploid, most likely a hybrid of wheat and emmer. Description Spelt is a species of '' Triticum'', a large stout grass similar to bread wheat. Its flowering spike is slenderer than that of bread wheat; when ripe, it bends somewhat from the vertical. The spike is roughly four-edged. The axis of the spike is brittle and divided into segments; it shatters into separate segments wh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Common Wheat
Common wheat (''Triticum aestivum''), also known as bread wheat, is a cultivated wheat species. About 95% of wheat produced worldwide is common wheat; it is the most widely grown of all crops and the cereal with the highest monetary yield. Taxonomy Numerous forms of wheat have evolved under human selection. This diversity has led to confusion in the naming of wheats, with names based on both genetic and morphological characteristics. List of common cultivars * Albimonte * Manital * Shirley * Hilliard Phylogeny Bread wheat is an allohexaploid a combination of six sets of chromosomes from different species. Of the six sets of chromosomes, four come from emmer (''Triticum turgidum'', itself a tetraploid) and two from '' Aegilops tauschii'' (a wild diploid goatgrass). Wild emmer arose from an even earlier ploidy event, a tetraploidy between two diploids, wild einkorn (''T. urartu'') and '' A. speltoides'' (another wild goatgrass). Free-threshing wheat is closely re ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Staple Food
A staple food, food staple, or simply staple, is a food that is eaten often and in such quantities that it constitutes a dominant portion of a standard diet for an individual or a population group, supplying a large fraction of energy needs and generally forming a significant proportion of the intake of other nutrients as well. For humans, a staple food of a specific society may be eaten as often as every day or every meal, and most people live on a diet based on just a small variety of food staples. Specific staples vary from place to place, but typically are inexpensive or readily available foods that supply one or more of the macronutrients and micronutrients needed for survival and health: carbohydrates, proteins, fats, minerals, and vitamins. Typical examples include grains (cereals and legumes), seeds, nuts and root vegetables (tubers and roots). Among them, cereals (rice, wheat, oat, maize, etc.), legumes ( lentils and beans) and tubers (e.g. potato, taro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
