sunflower - Sonneblume f: the genus of cultivated sunflower (H. annuus) includes more than 50 species; it contains one other economically important species, H. tuberosus, plus several ornamentals; wild species played an important role in genetic improvement of sunflower; sunflower was a common crop among American Indian tribes throughout North America; evidence suggests that the plant was cultivated by Indians in present-day Arizona and New Mexico about 3,000 BC; some archaeologists suggest that sunflower may have been domesticated before maize; sunflower was used in many ways throughout the various Indian tribes; seed was ground or pounded into flour for cakes, mush or bread; some tribes mixed the meal with other vegetables such as beans, squash, and maize; the seed was also cracked and eaten for a snack; there are references of squeezing the oil from the seed and using the oil in making bread; non-food uses include purple dye for textiles, body painting and other decorations; parts of the plant were used medicinally ranging from snakebite to other body ointments; the oil of the seed was used on the skin and hair; the dried stalk was used as a building material; the plant and the seeds were widely used in ceremonies; this exotic North American plant was taken to Europe by Spanish explorers some time around 1,500 AC; the plant became widespread throughout present-day Western Europe mainly as an ornamental, but some medicinal uses were developed; by 1716, an English patent was granted for squeezing oil from sunflower seed; sunflower became very popular as a cultivated plant in the 18th century; most of the credit is given to Peter the Great; the plant was initially used as an ornamental, but by 1769 literature mentions sunflower cultivated by oil production; by 1830, the manufacture of sunflower oil was done on a commercial scale; the Russian Orthodox Church increased its popularity by forbidding most oil foods from being consumed during Lent; however, sunflower was not on the prohibited list and therefore gained in immediate popularity as a food; by the early 19th century, Russian farmers were growing over 2 million acres of sunflower; during that time, two specific types had been identified: oil-type for oil production and a large variety for direct human consumption; government research programs were implemented. V. S. PUSTOVOIT developed a very successful breeding program at Krasnodar (Russia); oil contents and yields were increased significantly; today, the world's most prestigious sunflower scientific award is known as The Pustovoit Award; by the late 19th century, Russian sunflower seed found its way into the USA; by 1880, seed companies were advertising the “Mammoth Russian” sunflower seed in catalogues; this particular seed name was still being offered in USA in 1970, nearly 100 years later; a likely source of this seed movement to North America may have been Russian immigrants; the first commercial use of the sunflower crop in USA was silage feed for poultry; in 1926, the Missouri Sunflower Growers' Association participated in what is likely the first processing of sunflower seed into oil; Canada started the first official government sunflower breeding program in 1930; the basic plant breeding material utilized came from Mennonite immigrants from Russia; acreage spread because of oil demand; by 1946, Canadian farmers built a small crushing plant; acreage spread into Minnesota and North Dakota; in 1964, the Government of Canada licensed the Russian cultivar “Peredovik”; this variety produced high yields and high oil content; acreage in USA escalated in the late 1970's to over 5 million because of strong European demand for sunflower oil; this European demand had been stimulated by Russian exports of sunflower oil in the previous decades; during this time, animal fats were negatively impacted by cholesterol concerns; however, the Russians and later Bulgarians could no longer supply the growing demand, and European companies looked; Europeans imported sunflower seed that was then crushed in European mills; Western Europe continues to be a large consumer of sunflower oil today, but depends on its own production and breeding, Helianthus ssp.
