Rhobs al-Arsa (Citrus limon (L.) Burm. f. [1] ) is a very popular citrus fruit in Morocco. [2]
Rhobs al-Arsa is Arabic for bread of the garden, or "Garden Loaf". This citrus hybrid has many other names, such as Al-zanbu, Khoubs al-Arsa, Koubs al-Arsa, Kubbâd, Robs al-Arsa, Zamboa, Zanbo'a, and Zemboua.
The plant is an evergreen shrub with young green shoots, and rounded leaves that are green and shiny. The fruit is round and rather flat, with a small nipple at the apex, and an inverted ring around the nipple. Its skin is usually smooth. The pulp is acidic and fruity, with a sweet and pleasant albedo, slightly bitter bark. Maturity in February or March. It is cold-hardy to -2 °C / 3 °C and is an open-pollinated seedling.
The Rhobs al Arsa has long been viewed as a citron hybrid, though different cultivars have been suggested for the parents, for example, Moroccan citron as the male parent and sour orange as the female parent, [3] citron or lemon and a mandarin, [4] or citron and lime. [5] [6]
Detailed genomic analysis showed Rhobs al Arsa to be highly similar to several cultivars of the Citrus limetta , the limetta or Persian sweet lime, and likely shared a common origin with them, arising from a cross between citron (Citrus medica) and sour orange (Citrus × aurantium). The common lemon and several other hybrids arose from distinct hybridization events involving the same two species. [7] This proposed parentage was confirmed by a study of the native Sardinian citrus, the pompia (C. medica tuberosa), which was found to be genetically synonymous with the Rhobs el Arsa, both descended from the same hybrid, the product of a citron pollinating a sour orange, with the citron likely to be a native Italian variety such as the Diamante or the Common Poncire citrons. Such citrons had been cultivated together with the sour orange around the Mediterranean after the introduction of the latter by Moors in the 8th century, and frequent spontaneous crosses are likely to have occurred. Another Mediterranean variety, the Poncire de Collioure, was likewise found to be synonymous with Rhobs el Arsa and pompia. [8]
Kumquats, or cumquats in Australian English, are a group of small, angiosperm, fruit-bearing trees in the family Rutaceae. Their taxonomy is disputed. They were previously classified as forming the now-historical genus Fortunella or placed within Citrus, sensu lato. 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.
Citrus is a genus of flowering trees and shrubs in the rue family, Rutaceae. Plants in the genus produce citrus fruits, including important crops such as oranges, lemons, grapefruits, pomelos, and limes. The genus Citrus is native to South Asia, East Asia, Southeast Asia, Melanesia, and Australia. Various citrus species have been used and domesticated by indigenous cultures in these areas since ancient times. From there its cultivation spread into Micronesia and Polynesia by the Austronesian expansion ; and to the Middle East and the Mediterranean via the incense trade route, and onwards to Europe and the Americas.
The mandarin orange, also known as mandarin or mandarine, is a small, rounded 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.
A lime is a citrus fruit, which is typically round, green in color, 3–6 centimetres (1.2–2.4 in) in diameter, and contains acidic juice vesicles.
The citron, historically cedrate, is a large fragrant citrus fruit with a thick rind. It is said to resemble a 'huge, rough lemon'. It is one of the original citrus fruits from which all other citrus types developed through natural hybrid speciation or artificial hybridization. Though citron cultivars take on a wide variety of physical forms, they are all closely related genetically. It is used in Asian cuisine, traditional medicines, perfume, and religious rituals and offerings. Hybrids of citrons with other citrus are commercially more prominent, notably lemons and many limes.
Citrus limetta, alternatively considered to be a cultivar of Citrus limon, C. limon 'Limetta', is a species of citrus, commonly known as mousami, musami, sweet lime, sweet lemon, and sweet limetta, it is a member of the sweet lemons. It is small and round like a common lime in shape. It is a cross between the citron and a bitter orange.
Persian lime, also known by other common names such as seedless lime, Bearss lime and Tahiti lime, is a citrus fruit species of hybrid origin, known only in cultivation. The Persian lime is a triploid cross between Key lime and lemon.
Citrus bergamia, the bergamot orange, is a fragrant citrus fruit the size of an orange, with a yellow or green color similar to a lime, depending on ripeness.
The Key lime or acid lime is a citrus hybrid native to tropical Southeast Asia. It has a spherical fruit, 25–50 mm (1–2 in) in diameter. The Key lime is usually picked while it is still green, but it becomes yellow when ripe.
Rangpur, Citrus × limonia or Citrus reticulata × medica, sometimes called the rangpur lime, mandarin lime or lemandarin, is a hybrid between the mandarin orange and the citron. It is a citrus fruit with a very acidic taste and an orange peel and flesh.
Sweet lemon and Sweet lime refer to groups of citrus hybrids that contain low acid pulp and juice. They are hybrids often similar to non-sweet lemons or limes, but with less citron parentage. Sweet limes and lemons are not sharply separated:
The sweet lime, Citrus limettioides Tan., is often confused with the sweet lemon, C. limetta Tan., which, in certain areas, is referred to as "sweet lime". In some of the literature, it is impossible to tell which fruit is under discussion.
The ponderosa lemon is a citrus hybrid of a pomelo and a citron. It is not the same as the 'Yuma Ponderosa' lemon-pomelo hybrid used as citrus rootstock.
The lemon is a species of small evergreen tree in the flowering plant family Rutaceae, native to Asia, primarily Northeast India (Assam), Northern Myanmar, or China.
Citrus halimii, or mountain citron, is a citrus with sour fruit. Historically placed within the polyphyletic grouping of papedas, it has since been determined to be a wild species most closely related to the kumquats, and is not related to the true citron. It was first discovered and catalogued in 1973.
The micrantha is a wild citrus from the papeda group, native to southern Philippines, particularly islands of Cebu and Bohol. Two varieties are recognized: small-flowered papeda, locally known as biasong, and small-fruited papeda or samuyao.
The lumia is also called the pear lemon, since its shape resembles a pear. It is also called French lime and sometimes sweet lemon, even though it is not necessarily sweet.
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 limettioides, Palestinian sweet lime or Indian sweet lime or common sweet lime, alternatively considered a cultivar of Citrus × limon, C. × limon 'Indian Lime', is a low-acid lime used in Palestine for food, juice and rootstock. It is a member of the sweet limes. Like the Meyer lemon, it is the result of a cross between the citron and a mandarin/pomelo hybrid distinct from sweet and sour oranges.
Pompia, also called pumpia, sa pompia, spompia, and China citron, is a Citrus hybrid cultivated for its edible fruit.
Citrus medica x aurantium may refer to one of several hybrids between a citron and sour orange:
