Wheat is a grass widely cultivated for its seed, a cereal grain that is a staple food around the world. The many species of wheat together make up the genus Triticum ; the most widely grown is common wheat. The archaeological record suggests that wheat was first cultivated in the regions of the Fertile Crescent around 9600 BC. Botanically, the wheat kernel is a caryopsis, a type of fruit.
Einkorn wheat can refer either to a wild species of wheat (Triticum) or to its domesticated form. The wild form is T. boeoticum, and the domesticated form is T. monococcum. Einkorn is a diploid species 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.
Secale is a genus of the grass tribe Triticeae, which is related to barley (Hordeum) and wheat (Triticum). The genus includes cultivated species such as rye as well as weedy and wild rye species. The best-known species of the genus is the cultivated rye, S. cereale, which is grown as a grain and forage crop. Wild and weedy rye species help provide a huge gene pool that can be used for improvement of the cultivated rye.
Emmer wheat or hulled wheat is a type of awned wheat. Emmer is a tetraploid. The domesticated types are Triticum turgidum subsp. dicoccum and T. t. conv. durum. The wild plant is called T. t. subsp. dicoccoides. 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.
Chaff is dry, scale-like plant material such as the protective seed casings of cereal grains, the scale-like parts of flowers, or finely chopped straw. Chaff cannot be digested by humans, but it may be fed to livestock, ploughed into soil, or burned.
Durum wheat, also called pasta wheat or macaroni wheat, 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. It is the predominant wheat that grows in the Middle East.
Spelt, also known as dinkel wheat or hulled wheat, is a species of wheat that has been cultivated since approximately 5000 BCE.
Khorasan wheat or Oriental wheat is a tetraploid wheat species. The grain is twice the size of modern-day wheat, and has a rich, nutty flavor.
The founder crops or primary domesticates are a group of flowering plants that were domesticated by early farming communities in Southwest Asia and went on to form the basis of agricultural economies across Eurasia. As originally defined by Daniel Zohary and Maria Hopf, they consisted of three cereals, four pulses, and flax. Subsequent research has indicated that many other species could be considered founder crops. These species were amongst the first domesticated plants in the world.
Aaron Aaronsohn was a Romanian-born Ottoman agronomist, botanist, and political activist, who lived most of his life in Ottoman Syria. Aaronsohn was the discoverer of emmer, believed to be "the mother of wheat." He founded and was head of the NILI espionage network.
Rosh Pina or Rosh Pinna is a local council in the Korazim Plateau in the Upper Galilee on the eastern slopes of Mount Kna'an in the Northern District of Israel. It was established as Gei Oni in 1878 by local Jews from Safed but was nearly abandoned, except for the families of Yosef Friedman, Aharon Keller, and possibly a few others. In 1882, thirty Jewish families who had immigrated from Romania reestablished the settlement as a moshava called Rosh Pina. The town is one of the oldest Zionist settlements in Israel. In 2022 it had a population of 3,308.
Aegilops is a genus of Eurasian and North American plants in the grass family, Poaceae. They are known generally as goatgrasses. Some species are known as invasive weeds in parts of North America.
Common wheat, 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.
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.
Triticeae is a botanical tribe within the subfamily Pooideae of grasses that includes genera with many domesticated species. Major crop genera found in this tribe include wheat, barley, and rye; crops in other genera include some for human consumption, and others used for animal feed or rangeland protection. Among the world's cultivated species, this tribe has some of the most complex genetic histories. An example is bread wheat, which contains the genomes of three species with only one being a wheat Triticum species. Seed storage proteins in the Triticeae are implicated in various food allergies and intolerances.
Gluten is the seed storage protein in mature wheat seeds. It is the sticky substance in bread wheat which allows dough to rise and retain its shape during baking. The same, or very similar, proteins are also found in related grasses within the tribe Triticeae. Seed glutens of some non-Triticeae plants have similar properties, but none can perform on a par with those of the Triticeae taxa, particularly the Triticum species. What distinguishes bread wheat from these other grass seeds is the quantity of these proteins and the level of subcomponents, with bread wheat having the highest protein content and a complex mixture of proteins derived from three grass species.
Iraq ed-Dubb, or the Cave of the Bear, is an early Neolithic archeological site 7 km (4.3 mi) northwest of Ajlun in the Jordan Valley, in modern-day Jordan. The settlement existed before 8,000 BCE and experimented with the cultivation of founder crops, side by side with the harvesting of wild cereals. Along with Tell Aswad in Syria, the site shows the earliest reference to domestic hulled barley between 10,000 and 8,800 BCE. The site is located on a forested limestone escarpment above the Wadi el-Yabis in northwest Jordan. An oval-shaped stone structure was excavated along with two burials and a variety of animal and plant remains.
Triticum carthlicum Nevski, 1934, the Persian wheat, is a wheat with a tetraploid genome.
Triticum araraticum is a wild tetraploid species of wheat. T. araraticum is one of the least studied wheat species in the world.
Chogha Golan is an aceramic Neolithic archaeological site in the foothills of the Zagros Mountains in Iran, about 200 m (656 ft) from the right bank of the Konjan Cham River. Located in a semi-arid region about 30 km (19 mi) north of Mehran, Chogha Golan is one of the earliest aceramic Neolithic sites found in Iran. The people of Chogha Golan relied primarily on the exploitation of wild plants and hunting. Chogha Golan is notable for the early presence of domesticated emmer wheat, dating to around 9,800 BP as such the archaeobotanical remains from Chogha Golan shows the earliest record of long-term plant management in Iran.
