Carl Linnaeus>L.|synonyms=Secale fragile M.Bieb.}}Rye (Secale cereale) is a grass grown extensively as a grain, a cover crop and a forage crop. It is grown principally in an area from eastern and northern Europe into Russia. It is much more tolerant of cold weather and poor soil than other cereals, making it useful in those regions; its vigorous growth suppresses weeds, and provides abundant forage for animals early in the year. It is a member of the wheat tribe (Triticeae) which includes the cereals wheat and barley. Rye grain is used for bread, beer, rye whiskey, and animal fodder. In Scandinavia, rye was a staple food in the Middle-ages, and rye crispbread remains a popular food in the region. Around half of world production is in Europe; relatively little is traded between countries. A wheat-rye hybrid, triticale, combines the qualities of the two parent crops and is produced in large quantities worldwide. In European folklore, the Roggenwolf (“rye wolf“) is a carnivorous corn demon or Feldgeist. Origins (File:Wild rye.jpg|thumb|left|Wild rye)The rye genus Secale is in the grass tribe Triticeae, which contains other cereals such as barley (Hordeum) and wheat (Triticum).JOURNAL, Soreng, Robert J., Peterson, Paul M., Romaschenko, Konstantin, Davidse, Gerrit, Teisher, Jordan K., Clark, Lynn G., Barberá, Patricia, Gillespie, Lynn J., Zuloaga, Fernando O., 3, A worldwide phylogenetic classification of the Poaceae (Gramineae) II: An update and a comparison of two 2015 classifications, Journal of Systematics and Evolution, 55, 4, 2017, 1674-4918, 10.1111/jse.12262, 259–290, The generic name Secale, related to Italian segale and French seigle meaning “rye”, is of unknown origin but may derive from a Balkan language.Walde, Alois; Hofmann, Johann Baptist (1954) “secale”, in Lateinisches etymologisches Wörterbuch (in German), 3rd edition, volume 2, Heidelberg: Carl Winter, page 504 The English name rye derives from Old English ryge, related to Dutch rogge, German Roggen, Russian rozh, again all with the same meaning.WEB, rye (n.),www.etymonline.com/word/rye, Online Etymology Dictionary, 4 May 2024, Rye is one of several cereals that grow wild in the Levant, central and eastern Turkey and adjacent areas. Evidence uncovered at the Epipalaeolithic site of Tell Abu Hureyra in the Euphrates valley of northern Syria suggests that rye was among the first cereal crops to be systematically cultivated, around 13,000 years ago.JOURNAL, Hillman, Gordon, Hedges, Robert, Moore, Andrew, Colledge, Susan, Pettitt, Paul, 2001, New evidence of Lateglacial cereal cultivation at Abu Hureyra on the Euphrates,www.researchgate.net/publication/200033056, live, The Holocene, 11, 4, 383–393, 2001Holoc..11..383H, 10.1191/095968301678302823,web.archive.org/web/20211120221734/https://www.researchgate.net/publication/200033056_New_evidence_of_Late_Glacial_cereal_cultivation_at_Abu_Hureyra_on_the_Euphrates, November 20, 2021, July 12, 2016, 84930632, However, that claim remains controversial; critics point to inconsistencies in the radiocarbon dates, and identifications based solely on grain, rather than on chaff.JOURNAL, Colledge, Sue, Conolly, James, 2010, Reassessing the evidence for the cultivation of wild crops during the Younger Dryas at Tell Abu Hureyra, Syria, Environmental Archaeology, 15, 2, 124–138, 10.1179/146141010X12640787648504, 2010EnvAr..15..124C, 129087203, Domesticated rye occurs in small quantities at a number of Neolithic sites in Asia Minor (Anatolia, now Turkey), such as the Pre-Pottery Neolithic B Can Hasan III near Çatalhöyük,JOURNAL, Hillman, Gordon, 1978, On the Origins of Domestic rye: Secale Cereale: The Finds from Aceramic Can Hasan III in Turkey, Anatolian Studies, 28, 157–174, 10.2307/3642748, 3642748, 85225244, {{Subscription required|via=JSTOR}}JOURNAL, Sidhu, Jagdeep, Ramakrishnan, Sai Mukund, Shaukat, Ali, Amy, Bernado, Bai, Guihua, Sidrat, Abdullah, Ayana, Girma, Sehgal, Sunish, 2019, Assessing the genetic diversity and characterizing genomic regions conferring Tan Spot resistance in cultivated rye, PLOS ONE, 14, 3, e0214519, 2019PLoSO..1414519S, 10.1371/journal.pone.0214519, 6438500, 30921415, free, but is otherwise absent from the archaeological record until the Bronze Age of central Europe, c. 1800–1500 BCE.BOOK, Zohary, Daniel,books.google.com/books?id=1hHSYoqY-AwC&pg=PA62, Domestication of Plants in the Old World: The Origin and Spread of Domesticated Plants in Southwest Asia, Europe, and the Mediterranean Basin, Hopf, Maria, Weiss, Ehud, 2012, Oxford University Press, 978-0-19-954906-1, Oxford, 62, October 5, 2016, Google Books, It is likely that rye was brought westwards from Asia Minor as a secondary crop, meaning that it was a minor admixture in wheat as a result of Vavilovian mimicry, and was only later cultivated in its own right.JOURNAL, McElroy, J.

Cultivation File:Ivan Shishkin - Рожь - Google Art Project.jpg|thumb|upright=1.35|1878 oil painting A Rye Field by Ivan ShishkinIvan ShishkinSince the Middle Ages, people have cultivated rye widely in Central and Eastern Europe. It serves as the main bread cereal in most areas east of the France–Germany border and north of Hungary. In Southern Europe, it was cultivated on marginal lands.JOURNAL, Behre, Karl-Ernst, 1992, The history of rye cultivation in Europe,www.academia.edu/17566065, live, Vegetation History and Archaeobotany, 1, 3, 10.1007/BF00191554, 0939-6314,web.archive.org/web/20220323020416/https://www.academia.edu/17566065, March 23, 2022, February 17, 2022, 129518700, Rye grows well in much poorer soils than those necessary for most cereal grains. Thus, it is an especially valuable crop in regions where the soil has sand or peat. Rye plants withstand cold better than other small grains, surviving snow cover that would kill winter wheat. Winter rye is the most popular: it is planted and begins to grow in autumn. In spring, the plants develop rapidly. This allows it to provide spring grazing, at a time when spring-planted wheat has only just germinated.WEB, Growing Winter Rye in Scotland,www.fas.scot/article/growing-winter-rye-in-scotland/, Farm Advisory Service Scotland, 4 May 2024, 10 May 2023, The physical properties of rye affect attributes of the final food product such as seed size, surface area, and porosity. The surface area of the seed directly correlates to the drying and heat transfer time.JOURNAL, Jouki, Mohammad, Emam-Djomeh, Zahra, Khazaei, Naimeh, 2012, Physical Properties of Whole Rye Seed (Secale cereal), International Journal of Food Engineering, 8, 4, 10.1515/1556-3758.2054, 102003836, Smaller seeds have increased heat transfer, which leads to lower drying time. Seeds with lower porosity lose water more slowly during the process of drying.Rye is harvested like wheat with a combine harvester, which cuts the plants, threshes and winnows the grain, and releases the straw to the field where it is later pressed into bales or left as soil amendment. The resultant grain is stored in local silos or transported to regional grain elevators and combined with other lots for storage and distant shipment. Before the era of mechanised agriculture, rye harvesting was a manual task performed with scythes or sickles.BOOK, Jensen, Joan M.,books.google.com/books?id=v8OSv8QQQgoC&pg=PA47, Loosening the Bonds: Mid-Atlantic Farm Women, 1750–1850, Yale University Press (YUP), 1988, 978-0-300-04265-8, New Haven, 47, 2016-07-17, Google Books, BOOK, Jones, Peter M.,books.google.com/books?id=Jv3VCgAAQBAJ&pg=PA123, Agricultural Enlightenment: Knowledge, Technology, and Nature, 1750–1840, Oxford University Press (OUP), 2016, 978-0-19-102515-0, Oxford, 123, Agroecology Winter rye is any breed of rye planted in the autumn to provide ground cover for the winter.

Alkylresorcinols are phenolic lipids present in high amounts in the bran layer (e.g. pericarp, testa and aleurone layers) of wheat and rye (0.1–0.3% of dry weight).JOURNAL, Suzuki, Yoshikatsu, Esumi, Yasuaki, Yamaguchi, Isamu, 1999, Structures of 5-alkylresorcinol-related analogues in rye, Phytochemistry (journal), Phytochemistry, 52, 2, 281–289, 10.1016/S0031-9422(99)00196-X, 1999PChem..52..281S, Rye bread, including pumpernickel, is made using rye flour and is a widely eaten food in Northern and Eastern Europe.“Grains: Rye” {{Webarchive|url=https://web.archive.org/web/20181113134555www.bakkerijwiki.nl/index.php?t=2&h=5&s=8#Minderwaardig |date=November 13, 2018}} (in Dutch) bakkerijmuseum.nlJOURNAL, Prättälä, Ritva, Helasoja, Ville, Mykkänen, Hannu, The consumption of rye bread and white bread as dimensions of health lifestyles in Finland, Public Health Nutrition, 2000, 4, 3, 813–819, 10.1079/PHN2000120, 11415489, free, In Scandinavia, rye is widely used to make crispbread (); in the Middle Ages it was a staple food in the region, and it remains popular in the 21st century.NEWS, 2016-05-03, TuggmotstÃ¥nd, sv, Tough to chew, Dagens Nyheter,www.dn.se/mat-dryck/reportage/tuggmotstand/,web.archive.org/web/20160503231014/https://www.dn.se/mat-dryck/reportage/tuggmotstand/, dead, 2016-05-03, 2022-08-09, Rye grain is used to make alcoholic drinks, such as rye whiskey and rye beer.

{{further|Feldgeister}}(File:Roggenwolf and Rye Sheaves in coat of arms.jpg|thumb|upright|A Roggenwolf, a carnivorous spirit of the rye fields, with sheaves of harvested rye, on the coat of arms of the Bartensleben family )In European folklore, the Roggenwolf (“rye wolf“) is a carnivorous corn demon or Feldgeist, a field spirit shaped like a wolf.Golther, Wolfgang (2011)Germanische Mythologie: Vollständige Ausgabe. Marix-Verlag, Wiesbaden, {{ISBN|978-3-937715-38-4}} p. 200. The Roggenwolf steals children and feeds on them.Mannhardt, Wilhelm (2005) Wald- und Feldkulte: Band II.

Marix-Verlag, Wiesbaden, {{ISBN|978-3-937715-39-1}} p. 171. In contrast, the Roggenmuhme or Roggenmutter (“rye aunt” or “rye mother“) is an anthropomorphic female corn demon with fiery fingers. Her bosoms are filled with tar, and may end in tips of igneous iron. Her bosoms are also long, and as such must be thrown over her shoulders when she runs. The Roggenmuhme is completely black or white, and in her hand she has a birch or whip from which lightning sparks. She can change herself into different animals; such as snakes, turtles, frogs and others.Mannhardt, Wilhelm (2014) Die Korndämonen: Beitrag zur germanischen Sittenkunde. Bremen University Press, Bremen, {{ISBN|978-3-95562-798-0}} p. 20.The classical scholar Carl A. P. Ruck writes that the Roggenmutter was believed to go through the fields, rustling like the wind, with a pack of rye wolves running after her. They spread ergot through the sheaves of harvested rye. According to Ruck, they then lured children into the fields to nurse on the infected grains “like the iron teats of the Roggenmutter”. The enlarged reddish ergot-infected grains were known as Wulfzähne (wolf teeth).JOURNAL, Ruck, Carl, Carl A. P.
