Tangelo

The early maturing Orlando tangelo is noted for its rich juiciness, mild and sweet flavor, large size, distinct zesty smell, and flat-round shape without a characteristic knob. California/Arizona tangelos have a slightly pebbled texture, vibrant interior and exterior color, very few seeds, and a tight-fitting rind. Orlando tangelos are available from mid-November to the beginning of February. The tangelo originated as a cross between a Duncan grapefruit and a Dancy mandarin.[2] W. T. Swingle of the United States Department of Agriculture (USDA) is credited with creating the hybrid in 1911. When the Orlando tangelo was first cultivated, it was known by the name Lake tangelo. The trees of this variety grow to a large size and are easily recognized by their cup-shape leaves. Orlando tangelos are recognized as one of the more cold-tolerant varieties. Northern Florida grows significantly fewer tangelos, but they are much sweeter due to climate.

The Minneola tangelo (also known as the Honeybell) is a cross between a Duncan grapefruit and a Dancy mandarin, and was released in 1931 by the USDA Horticultural Research Station in Orlando. It is named after Minneola, Florida. Most Minneola tangelos are characterized by a stem-end neck, which tends to make the fruit appear bell-shaped. Because of this, it is also called the Honeybell in the gift fruit trade, where it is one of the most popular varieties. Both Minneolas and Honeybells are usually fairly large, typically 3–3 ¹⁄₂ inches (76–89 mm) in diameter; the Honeybells tend to be larger and sweeter. The peel color, when mature, is a bright-reddish-orange color. The rind of the Minneola is relatively thin, while the rind of the Honeybell is slightly thicker. Both the Minneola and Honeybell Tangelo peel rather easily. Both are very juicy. Both the Minneola and the Honeybell are not strongly self-fruitful, and yields will be greater when interplanted with suitable pollenizers such as Temple tangor, Sunburst tangerine, or possibly Fallglo tangerine. It tends to bear a good crop every other year.[3] In the Northern Hemisphere the fruit matures in the December–February period, with January being the peak.

The Jamaican tangelo, marketed under proprietary names ugli fruit and uniq fruit, is a spontaneous hybrid discovered about 1920 on the island of Jamaica, with a rough, wrinkled, greenish-yellow rind. Its exact parentage has not been determined, but it is thought to be a tangerine/grapefruit hybrid.

A hybrid propagated by growers, the K-Early is an early-ripening cultivar which gained a notoriously bad reputation.[4]

Hybrid between a 'Bowen' grapefruit and a 'Dancy' tangerine. The fruit is deep red-orange in color and oblate in shape with a thin and firm peel, and is not necked. It has 11-13 juicy segments and a pleasant, subacid flavor. It has 20-25 small seeds. The tree is high-yielding and scab-resistant.[5]

A tangerine-grapefruit hybrid developed by Walter Tennyson Swingle in 1899. The fruit is oblate to obovate in shape, slightly rough, and medium to large in size. The peel is light orange in color and is of a medium thickness; the pulp inside is pale to deep orange. It has 10-12 juicy segments and a rich subacid to sweet flavor. There are 10-25 slender seeds inside. It ripens from December to March. The tree is high-yielding and is well-adapted to hot and dry regions, although the fruit ships poorly.[6]

In 2011, a troop of baboons were attracted to the higher sweetness of a new likely mutation in a Minneola planting in Cape Town, South Africa, prompting its propagation.[7]
