Sweet oranges are the most important of the citrus fruits. (See also citrus fruits.) Varieties vary from early ripening - about 8 months from bloom - to late - up to 16 months from bloom. There are three main groups: The normal fruited, without navels and with light orange colored flesh; the navel oranges, with a distinct navel development at the styler end; and blood oranges, with red flesh and juice. The latter are little grown commercially in the U.S. Sweet oranges vary in size from 2 inches upward in diameter, are generally round to oblong in shape, and have a medium thick and tough rind. Although 73 varieties are listed by Webber (THE CITRUS INDUSTRY) major production in the U.S. is of 6 varieties: Valencia, Washington Navel, Hamlin, Parson Brown, Pineapple and Temple.

Season, bloom to harvest: 8 to 16 months, depending on variety and area of production.

Production in U.S.: About 4,500,000 tons.

Use: Fresh, canned and frozen juice, canned segments, marmalade.

Part of fruit consumed: Interior segments. Some rind is used in marmalade; dried rind from processing plants is used as livestock feed.
