Foxtail millet, scientific name Setaria italica (synonym Panicum italicum L.), is an annual grass grown for human food. It is the second-most widely planted species of millet, and the most grown millet species in Asia. The oldest evidence of foxtail millet cultivation was found along the ancient course of the Yellow River in Cishan, China, carbon dated to be from around 8,000 years before present. [1] [2] [3] Foxtail millet has also been grown in India since antiquity.[ citation needed ]
Other names for the species include dwarf setaria, foxtail bristle-grass, giant setaria, green foxtail, Italian millet, German millet, and Hungarian millet. [4] [5]
Foxtail millet is an annual grass with slim, vertical, leafy stems which can reach a height of 120–200 cm (3 ft 11 in – 6 ft 7 in).
The seedhead is a dense, hairy panicle 5–30 cm (2 in – 1 ft 0 in) long.
The small seeds, around 2 millimetres (3⁄32 in) in diameter, are encased in a thin, papery hull which is easily removed in threshing. Seed color varies greatly between varieties.

Common names for foxtail millet in other languages spoken in the countries where it is cultivated include:
In India, foxtail millet is still an important crop in its arid and semi-arid regions. [13] In South India, it has been a staple diet among people for a long time from the Sangam period. It is referred to often in old Tamil texts and is commonly associated with Lord Muruga and his consort Valli.
In Karbi Anglong district of Assam, India, millets have been an integral part of the food system of the Karbis as well as the Jhum fields. Hanjangmilen, Karbi name of foxtail millets have been visible in the Jhum fields in the past. But today it is hardly visible in the Jhum fields. But farmers are now bringing the traditional crop back into their food system which needs little water, grows well on poor soil, is fast-growing and suffers from very few diseases.
In China, foxtail millet was the main staple food in the north before Sung Dynasty, when wheat started to become the main staple food. It is still the most common millet and one of the main food crops in the dry northern part of the country, especially among the poor. In Southeast Asia, foxtail millet is commonly cultivated in its dry, upland regions. [14] In Europe and North America it is planted at a moderate scale for hay and silage, and to a more limited extent for birdseed.
In the northern Philippines, foxtail millet was once an important staple crop, until its later replacement by wet-rice and sweet potato cultivation. [15]
It is a warm season crop, typically planted in late spring. Harvest for hay or silage can be made in 65–70 days with a typical yield of 15,000–20,000 kilograms per hectare (6.7–8.9 short ton/acre) of green matter or 3,000–4,000 kilograms per hectare (1.3–1.8 short ton/acre) of hay. Harvest for grain is in 75–90 days with a typical yield of 800–900 kilograms per hectare (0.36–0.40 short ton/acre) of grain. Its early maturity and efficient use of available water make it suitable for raising in dry areas.
Diseases of foxtail millet include leaf and head blast disease caused by Magnaporthe grisea , smut disease caused by Ustilago crameri , and green ear caused by Sclerospora graminicola . The unharvested crop is also susceptible to attack by birds and rodents. Insect pests include Atherigona atripalpis , the foxtail millet shoot fly. [16]
Insect pests include: [17]
The wild ancestor of foxtail millet has been securely identified as Setaria viridis , which is interfertile with foxtail millet; wild or weedy forms of foxtail millet also exist. Zohary and Hopf note that the primary difference between the wild and cultivated forms is "their seed dispersal biology. Wild and weedy forms shatter their seed while the cultivars retain them." [18] The reference genome for foxtail millet was completed in 2012. [13] [19] [20] Genetic comparisons also confirm that S. viridis is the antecedent of S. italica. [13]
The earliest evidence of the cultivation of this grain comes from the Peiligang culture of China, which also cultivated Panicum miliaceum , but foxtail millet became the predominant grain only with the Yangshao culture. [18] More recently, the Cishan culture of China has been identified as the earliest to domesticate foxtail millet around 6500–5500 BC. [21] [3]
The earliest evidence for foxtail millet cultivation outside of its native distribution is at Chengtoushan in the Middle Yangtze River region, dating to around 4000 BC. [14] In southern China, foxtail millet reached the Chengdu Plain (Baodun) at around 2700 BC [22] and Guangxi (near the Vietnamese border) at around 3000 BC. [14] Foxtail millet also reached Taiwan (Nankuanli, Dapenkeng culture) at around 2800 BC [23] and the Tibetan Plateau (Karuo) at around 3000 BC. [14]
Foxtail millet likely reached Southeast Asia via multiple routes. [14] The earliest evidence for foxtail millet in Southeast Asia comes from various sites in the Khao Wong Prachan Valley in central Thailand, with the site at Non Pa Wai providing the earliest date with direct AMS dating to around 2300 BC. [14] [24]
The earliest evidence for foxtail millet in East Siberia comes from the archaeological site at Krounovka 1 in Primorsky Krai, dating to around 3620–3370 BC. [13] [25] The earliest direct evidence for foxtail millet in Korea come from Dongsam-dong Shell Midden, a Jeulmun site in southern Korea, with a direct AMS date of around 3,360 BC. [13] [26] In Japan, the earliest evidence for foxtail millet comes from the Jōmon site at Usujiri in Hokkaido, dating to around 4,000 BP. [13]
Foxtail millet arrived in Europe later; carbonized seeds first appear in the second millennium BC in central Europe. The earliest definite evidence for its cultivation in the Near East is at the Iron Age levels at Tille Hoyuk in Turkey, with an uncorrected radiocarbon date of about 600 BC. [18]
As with some other cereals the waxy gene contributes to glutinousness. [3] The wild relative Setaria viridis provides genetic resources useful for foxtail breeding. [27] [28]
One study found that – for the rabi crop in Tamil Nadu – breeding for foxtail yield should begin from germplasm with the most productive tillers, medium panicle length and medium duration. [29] [30] [31]
Millets are a highly varied group of small-seeded grasses, widely grown around the world as cereal crops or grains for fodder and human food. Most millets belong to the tribe Paniceae.
Panicum miliaceum is a grain crop with many common names, including proso millet, broomcorn millet, common millet, hog millet, Kashfi millet, red millet, and white millet. Archaeobotanical evidence suggests millet was first domesticated about 10,000 BP in Northern China. Major cultivated areas include Northern China, Himachal Pradesh of India, Nepal, Russia, Ukraine, Belarus, the Middle East, Turkey, Romania, and the Great Plains states of the United States. About 500,000 acres are grown each year. The crop is notable both for its extremely short lifecycle, with some varieties producing grain only 60 days after planting, and its low water requirements, producing grain more efficiently per unit of moisture than any other grain species tested. The name "proso millet" comes from the pan-Slavic general and generic name for millet.
The 9th millennium BC spanned the years 9000 BC to 8001 BC. In chronological terms, it is the first full millennium of the current Holocene epoch that is generally reckoned to have begun by 9700 BC. It is impossible to precisely date events that happened around the time of this millennium and all dates mentioned here are estimates mostly based on geological and anthropological analysis, or by radiometric dating.
North China (华北) is a geographical region of China, consisting of two direct-administered municipalities, two provinces, and one autonomous region.
Common millet is a common name for several plants and may refer to:
Panicum italicum may refer to two different species of plants:
Echinochloa is a very widespread genus of plants in the grass family and tribe Paniceae. Some of the species are known by the common names barnyard grass or cockspur grass.
Setaria is a widespread genus of plants in the grass family. The name is derived from the Latin word seta, meaning "bristle" or "hair", which refers to the bristly spikelets.
Panicum mosaic virus (PMV) is a positive-sense single-stranded RNA viral pathogen that infects plant species in the panicoid tribe of the grass family, Poaceae. The pathogen was first identified in Kansas in 1953 and most commonly causes disease on select cultivars of turf grass, switchgrass, and millet. The disease most commonly associated with the panicum mosaic virus pathogen is St. Augustine Decline Syndrome, which infects species of turf grass and causes chlorotic mottling. In addition to St. Augustine Decline, panicum mosaic virus is responsible for chlorotic streaking and mild green mosaicking in select cultivars of switchgrass and millet.
Panicum antidotale Retz. is a tall, coarse, woody perennial grass throughout the Himalaya and the Upper Gangetic Plain and specifically in various regions of the Indian state of Punjab and the Pakistan province of Punjab and the neighbouring areas of these regions. The plant has strong spreading rhizomes.
Panicum sumatrense, known as little millet, is a species of millet in the family Poaceae.
Setaria viridis is a species of grass known by many common names, including green foxtail, green bristlegrass, and wild foxtail millet. It is sometimes considered a subspecies of Setaria italica. It is native to Eurasia, but it is known on most continents as an introduced species and is closely related to Setaria faberi, a noxious weed. It is a hardy grass which grows in many types of urban, cultivated, and disturbed habitat, including vacant lots, sidewalks, railroads, lawns, and at the margins of fields. It is the wild antecedent of the crop foxtail millet.
The Jeulmun pottery period is an archaeological era in Korean prehistory broadly spanning the period of 8000–1500 BC. This period subsumes the Mesolithic and Neolithic cultural stages in Korea, lasting ca. 8000–3500 BC and 3500–1500 BC, respectively. Because of the early presence of pottery, the entire period has also been subsumed under a broad label of "Korean Neolithic".
Xinglonggou is a Neolithic through Bronze Age archaeological site complex consisting of three separate sites. The sites are located on a loess slope above the left bank of the Mangniu River north of the Qilaotu Mountains in Aohan Banner, Inner Mongolia, China. Xinglonggou is one of the most important sites of the early Neolithic Xinglongwa culture and provides evidence for the development of millet cultivation. The millet assemblage at Xinglonggou consists primarily of broomcorn millet. Xinglonggou is one of the few, early Neolithic sites in China for which systematic flotation has been performed.
Atherigona is a genus of flies in the family Muscidae.
Our analytical results of both phytoliths and biomolecular components have established that the earliest cereal remains stored in the Cishan Neolithic sites, during ca. 10,300–8,700 cal yr BP, are not foxtail millet, but only common millet. After 8,700 cal yr BP, the grain crops gradually contained 0.4–2.8% foxtail millet .
