Valencia orange

The Valencia orange is a sweet orange cultivar named after the famed oranges in València, Spain. It was first hybridized by pioneer American agronomist and land developer William Wolfskill in the mid-19th century on his farm in Santa Ana, southern California, United States, North America.

History
William Wolfskill (1798–1866) was an American born in Kentucky and reared in Missouri. He became a Mexican citizen in the 1820s, when he was in his 20s, while working in Santa Fe, New Mexico, as a fur trapper and then migrating to California, which was still part of Mexico at that time. He was given a land grant as a naturalized Mexican citizen under Mexican government rules. He cultivated numerous vineyards and grape varietals and was the largest wine producer in the region. He continued to buy land and later had sheep ranches as well as developing extensive citrus orchards. He hybridized the Valencia orange, a sweet orange, naming it after València, Spain, which has a reputation for its sweet orange trees.

Before his death in 1866, Wolfskill sold his patented Valencia hybrid to the Irvine Ranch owners, who planted nearly half their lands in its cultivation. The success of this crop in Southern California led to the naming of Valencia, California. It became the most popular juice orange in the United States.

In the mid-20th century, Florida botanist Lena B. Smithers Hughes introduced major improvements to the Valencia orange, developing virus-free strains for budwood production. These were so successful that, by 1983, the Hughes Valencia bud line made up some 60 percent of all Valencia oranges propagated for cultivation in Florida.

In 1988, Merleen Smith, a woman in Ventura County, California, contacted her local farm advisor on the suspicion that her neighbor was poisoning her tree. Investigators found that it was a pigmented bud sport of a conventional Valencia orange tree. The orange cultivar 'Smith Red Valencia' (with red insides) now bears her name.

Description
Primarily grown for processing and orange juice production, Valencia oranges have seeds, varying in number from zero to nine per fruit. Its excellent taste and internal color make it desirable for the fresh fruit markets, too. The fruit has an average diameter of 2.7 to 3 in, and a piece of this fruit which weighs 96 g has 45 calories and 9 grams of sugar. After bloom, it usually carries two crops on the tree, the old and the new. The commercial harvest season in Florida runs from March to June. Worldwide, Valencia oranges are prized as the only variety of orange in season during summer.

In 2012, the genome of the orange was sequenced, and was found to have 29,445 protein-coding genes. It was also found that the sweet orange originated from a backcross hybrid between pomelo and mandarin orange.

The Valencia orange undergoes nucellar embryony in both fertilized and unfertilized conditions of the ovule.

Hamlin
This cultivar was discovered by A. G. Hamlin near Glenwood, Florida, in 1879. The fruit is small, smooth, not highly colored, and juicy, with a pale yellow colored juice, especially in fruits that come from lemon rootstock. The fruit may be seedless, or may contain a number of small seeds. The tree is high-yielding and cold-tolerant and it produces good quality fruit, which is harvested from October to December. It thrives in humid subtropical climates. In cooler, more arid areas, the trees produce fruit too small for commercial use. Trees from groves in hammocks or areas covered with pine forest are budded on sour orange trees, a method that gives a high solids content. On sand, they are grafted on rough lemon rootstock. The Hamlin orange has been one of the most popular juice oranges in Florida and replaced the Parson Brown variety as the principal early-season juice orange.

 * Lue Gim Gong: grown in Florida, is an early scion developed by Lue Gim Gong, a Chinese immigrant known as the "Citrus Genius"; in 1888, Lue cross-pollinated two orange varieties—the Hart's late Valencia and the Mediterranean Sweet—and obtained a fruit both sweet and frost-tolerant; this variety was propagated at the Glen St. Mary Nursery, which in 1911 received the Silver Wilder Medal by the American Pomological Society; originally considered a hybrid, the Lue Gim Gong orange was later found to be a nucellar seedling of the Valencia type, which is properly called Lue Gim Gong; since 2006, the Lue Gim Gong variety is grown in Florida, although sold under the general name Valencia
