Conteúdo: | The cultivated sunflower [Helianthus annuus var. macrocarpa (DC.) Ck11.] is one of the four most important annual crops in the world grown for edible oil.  There is archaelogical evidence that the present sunflower with a single head was grown in the prehistoric North American Indian culture and may have been domesticated before the introduction of corn (Zea mays L.). The Indian used the crop as a source of food. Early Spanish explorers introduced the plant to Europe where it was largely used as an ornamental. Extensive use of sunflower as a source of edible oil began in 1830 after the crop reached Russia. The sunflower has become the main source of edible oil in the USSR, other eastern European countries, and Argentina. The crop was re-introduced to North America from Europe in the late 19th century with initial interest being its use as silage. Commercial extraction of oil began in 1946 in Manitoba when Canada promoted it as an oilseed crop. Some of the crop grown in North America is for confectionery and birdbeef purposes. In the last 10 to 15 years, production increased greatly in some other countries, including the United States where plantings in 1977 where approximately 1,000,000 ha. Much of the stimulus in the United States has been due to the importation of Russian germplasm with oil content consistently above 40%, and the discovery of a cytoplasmic male sterile and fertility re-storer system which is used to produce hybrid seed. The introduction of hybrid seed has improved the yield and uniformity of the
