Citrus fruits are popular worldwide, and new types of citrus fruits are constantly being created in order to develop larger, tastier fruits. When naming hybrid citrus, prefixes and suffixes are used to give clues to the origin of the breeding. When crossed with grapefruit, for instance, the suffix used is 'ummelo' or 'ela'. Sweet orange crosses use the prefix 'or' or the suffix 'ange'. The tangerine cross uses the prefix 'tan' or suffix 'andarin'.
Page Citrus Hybrid
The Page citrus hybrid is a cross between the Minneola tangelo and Clementine mandarin. The Minneola is a grapefruit and tangerine mix, so the Page is actually 3/4 tangerine and 1/4 grapefruit. The Page was developed in 1942 in Orlando, Florida. It was first marketed in 1963. The Page ripens early, but has several problems that have stopped its commercial growth. These problems include overly small fruit size and its susceptibility to scab fungus disease.
Osceola Citrus Hybrid
Osceola citrus hybrid is a cross between a Clementine mandarin and an Orlando tangelo. Developed in 1942, it was released to the public in 1959. It never moved into the commercial citrus market because of its bland taste. It is a mixture of 3/4 tangerine and 1/4 grapefruit that resembles a tangerine. Its fruit is 2 to 3 inches in diameter with a thin, easy-to-peel skin. Scab fungus is known to attack this citrus and the fruit rind puffs up if it is left on the tree for an extended period of time.
Ambersweet Orange Hybrid
Ambersweet orange hybrid is a cross between Clementine and Orlando oranges. It produces 2 1/2- to 3 3/4-inch fruit that is seedless if not cross pollinated. The fruit is harvested in October through January. Ambersweet was released in 1989. It is classified as an orange with an easy peel to remove. It resembles a navel orange. The fruit is fuzzy when immature.
Temple Tangor Hybrid
The Temple tangor is a tangerine and orange hybrid. It originated in Jamaica in the late 1800s. The Temple tangor was named in 1919. The fruit tree has a high heat requirement to set fruit and is extremely cold sensitive. The fruit size is 2 3/4 to 3 inches and slightly flattened in shape. The skin is thick, but it is easy to peel. The rind color is a deep reddish-orange, as it matures in January to March. It is highly susceptible to scab fungus and is a target for aphid infestations.
