Orangequat
The madarinquat, also misleadingly called orangequat, is any cross between a mandarin and a kumquat (Fortunella crassifolia). Mandarinquats are members of the citrofortunella group. The variety Nippon orangequat was first introduced in 1932 by Dr. Eugene May of the USDA as a hybrid between the Meiwa kumquat and the Satsuma mandarin. A second variety, the Indio mandarinquat, was discovered as an open-pollinated seedling from a Nagami kumquat with an unknown pollen parent. Description This is a small, round, orange fruit, which is larger than a kumquat. The fruit ranges from in circumference. Mandarinquat trees are small to medium in size; the leaves are usually long and narrow and dark green in color. The trunk and branches of the trees are slightly narrow, given the size of the trees. These trees can be seen with fruits on them through many of the colder months, since that is the season for Mandarinquat growing. Mandarinquat have not been genetically altered to be resistant ...

Kumquat
Kumquats (; zh, 金桔), or cumquats in Australian English, are a group of small fruit-bearing trees in the flowering plant family Rutaceae. Their taxonomy is disputed. They were previously classified as forming the now-historical genus ''Fortunella'' or placed within ''Citrus'', . Different classifications have alternatively assigned them to anywhere from a single species, ''C. japonica'', to numerous species representing each cultivar. Recent genomic analysis would define three pure species, ''Citrus hindsii'', ''C. margarita'' and ''C. crassifolia'', with ''C. x japonica'' being a hybrid of the last two. The edible fruit closely resembles the orange (''Citrus sinensis'') in color and shape but is much smaller, being approximately the size of a large olive. The kumquat is a fairly cold-hardy citrus. Etymology The English name "kumquat" is a borrowing of the Cantonese ''gāmgwāt'' (). Origin The kumquat plant is native to Southern China. The historical reference to kum ...

Mandarin Orange
The mandarin orange (''Citrus reticulata''), also known as the mandarin or mandarine, is a small citrus tree fruit. Treated as a distinct species of orange, it is usually eaten plain or in fruit salads. Tangerines are a group of orange-coloured citrus fruit consisting of hybrids of mandarin orange with some pomelo contribution. Mandarins are smaller and oblate, unlike the spherical common oranges (which are a mandarin–pomelo hybrid). The taste is considered sweeter and stronger than the common orange. A ripe mandarin is firm to slightly soft, heavy for its size, and pebbly-skinned. The peel is thin, loose, with little white mesocarp, so they are usually easier to peel and to split into segments. Hybrids usually have these traits to a lesser degree. The mandarin is tender and is damaged easily by cold. It can be grown in tropical and subtropical areas. According to genetic studies, the mandarin was one of the original citrus species; through breeding or natural hybridization ...

Citrofortunella
Citrofortunella are a large group of commercial hybrids that cross the kumquat with other citrus. In the system of citrus taxonomy established by Swingle, kumquats were placed in a different genus, '' Fortunella'', from ''Citrus'', which included citron, mandarin orange, pomelo and papedas. The result of genetic crosses between kumquats and these other citrus would then be intergeneric hybrids, so a novel genus name was coined for them in 1975, by compounding the names of the contributing genera to form ''Citrofortunella''. That the genus is of a hybrid nature is represented by a multiplication sign before the genus name, for example × ''Citrofortunella microcarpa''. Recent phylogenetic work has shown kumquats to fall within ''Citrus'' rather than belonging to a distinct genus, meaning these would no longer be considered intergeneric hybrids, and use of ''Citrofortunella'' as a distinct genus name for these hybrids loses taxonomic validity. All would be placed instead within ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Satsuma Mandarin
''Citrus unshiu'' is a semi-seedless and easy-peeling citrus species, also known as miyagawa mandarin, unshu mikan, cold hardy mandarin, satsuma mandarin, satsuma orange, naartjie, and tangerine. ''Citrus unshiu'' was named after Unshu (Wenzhou), a famous production area of mandarin oranges in China, in the late Edo period of Japan. It is said to have originated in either Japan or China, and because of its name, it is often described as originating in China;The Satsuma Mandarin University of Florida "probable origin in Kyushu islands, Japan or imported from China to Japan." however, due to multiple genetic studies conducted in the 2010s, the theory that the maternal species ...

The Citrus Industry
''The Citrus Industry'' is a book consisting of five volumes of scientific and experimental information on all the citrus species and varieties, originals as well as hybrids. The book was produced by scientists associated with the University of California Citrus Experiment Station, and contains fundamental information on the variety description and cost effectiveness of growing, as well technical support for citrus cultivation. The name reflects its aim to support the success of the citrus industry in all means. It is considered the Bible of citrus farming.

Citrus Canker
Citrus canker is a disease affecting ''Citrus'' species caused by the bacterium ''Xanthomonas'' (''X.axonopodis; X. campestris''). Infection causes lesions on the leaves, stems, and fruit of citrus trees, including lime, oranges, and grapefruit. While not harmful to humans, canker significantly affects the vitality of citrus trees, causing leaves and fruit to drop prematurely; a fruit infected with canker is safe to eat, but too unsightly to be sold. The disease, which is believed to have originated in Southeast Asia, is extremely persistent when it becomes established in an area. Citrus groves have been destroyed in attempts to eradicate the disease. Countries like Brazil and the United States also suffer from canker outbreaks. Biology ''Xanthomonas axonopodis'' is a rod-shaped Gram-negative bacterium with polar flagella. The bacterium has a genome length around 5 megabase pairs. A number of types of citrus canker diseases are caused by different pathovars and variants ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Citrus Hybrids
Citrus taxonomy refers to the botanical classification of the species, varieties, cultivars, and graft hybrids within the genus ''Citrus'' and related genera, found in cultivation and in the wild. Citrus taxonomy is complex and controversial. Cultivated citrus are derived from various citrus species found in the wild. Some are only selections of the original wild types, many others are hybrids between two or more original species, and some are backcrossed hybrids between a hybrid and one of the hybrid's parent species. Citrus plants hybridize easily between species with completely different morphologies, and similar-looking citrus fruits may have quite different ancestries. Some differ only in disease resistance. Conversely, different-looking varieties may be nearly genetically identical, and differ only by a bud mutation. Detailed genomic analysis of wild and domesticated citrus cultivars has suggested that the progenitor of modern citrus species expanded out of the Himalaya ...
