A Group (previously cultivar-group ) is a formal category in the International Code of Nomenclature for Cultivated Plants ( ICNCP ) used for cultivated plants ( cultivars ) that share a defined characteristic. It is represented in a botanical name by the symbol Group or Gp . "Group" or "Gp" is always written with a capital G in a botanical name, or epithet . The Group is not italicized in a plant's name. The ICNCP introduced the term and symbol "Group" in 2004, as a replacement for the lengthy and hyphenated "cultivar-group", which had previously been the category's name since 1969. For the old name "cultivar-group", the non-standard abbreviation cv. group or cv. Group is also sometimes encountered. There is a slight difference in meaning, since a cultivar-group was defined to comprise cultivars, whereas a Group may include individual plants. The cultivar-groups, in turn, replaced the similar category convariety ( convar. ), which did not necessarily contain named varieties.
11-483: Mirabelle plum ( Prunus domestica subsp. syriaca ) is a cultivar group of plum trees of the genus Prunus . It is believed that the plum was cultivated from a wild fruit grown in Anatolia . The mirabelle is identified by its small, oval shape, smooth-textured flesh, and especially by its red, or dark yellow colour which becomes flecked in appearance. They are known for being sweet and full of flavour. The fruit
22-549: A different taxonomic classification, such as a subspecific name (typically a form or variety name, given in italics) after the genus and species. A Group is usually united by a distinct common trait, and often includes members of more than one species within a genus. For example, early flowering cultivars in the genus Iris form the Iris Dutch Group. A plant species that loses its taxonomic status in botany, but still has agricultural or horticultural value, meets
33-629: A gala of celebration. Import of mirabelles to the United States is generally restricted. Cultivar group The ICNCP distinguishes between the terms "group" and "Group", a "group" being "an informal taxon not recognized in the ICBN ", while a "Group" is the formal taxon defined by the ICNCP (see above). This categorization does not apply to plant taxonomy generally, only to horticultural and agricultural contexts. Any given Group may have
44-589: A specific geographical zone of production. The city of Metz dedicates two weeks to the Mirabelle plum during the popular Mirabelle Festival held in August. During the festival, in addition to open markets selling fresh prunes, mirabelle tarts, and mirabelle liquor, there is live music, fireworks, parties, art exhibits, a parade with floral floats and competition, and the crowning of the Mirabelle Queen and
55-422: A terminal . character ). A cultivar group may be surrounded by parentheses (round brackets) for clarity in long epithets: ICNCP illustrates this order consistently, though in actual practice the cultivar name in single quotation marks may come before that of the cultivar group (with or without parentheses): "Group" is translated in non-English material, and uses the word order of the language in question, but
66-745: Is always capitalized. Translation may or may not be applied to the name itself. For example, "Chater's Double Group" may appear as " Groupe Chater's Double" in French (retaining the English name but translating "Group" and using French word order), yet with full translation as " Chaters Doppelte Gruppe " in German. Groups are not necessarily mutually exclusive. For example, the same potato may be designated Solanum tuberosum Maincrop Group, or Solanum tuberosum Red-skinned Group, or given with both as Solanum tuberosum Maincrop Red-skinned Group, "depending on
77-482: Is primarily used in fruit preserves and dessert pies , and its juice is commonly fermented for wine or distilled into plum brandy . Some 90% of mirabelle plums grown commercially are made into either jam (70%) or eau de vie (20%). The mirabelle reaches maturity and is harvested from July to mid-September in the Northern Hemisphere. The traditional method of shaking the trees is now mechanized, but
88-536: Is smaller, less hard, and less sweet, and has no small red spots on the skin. It is very good for jam, while the Nancy type is better as fresh fruit as it is sweeter. Since 1996 the mirabelle de Lorraine has been recognized and promoted by the EU as a high-quality regional product, with a Protected Geographical Indication (PGI). This label guarantees a minimum fruit size (22 mm) and sugar content, and can only be used in
99-439: Is used after a hyphen in a hyphenated term, like "Red-skinned", and for conjunctions and prepositions except in the first word of the name). This is followed by the capitalized word "Group". The combined Group name is not italicized or otherwise stylized, and follows the italicized Latin epithet. It can also be used after a vernacular name for the species, genus, or other category. Examples: "Group" may be abbreviated "Gp" (without
110-455: The criteria for a cultivar group, and its former botanical name can be reused as the name of its cultivar group. For example, Hosta fortunei is usually no longer recognized as a species, and the ICNCP states that the epithet fortunei can be used to form Hosta Fortunei Group. Every word in a Group name is capitalized (unless that conflicts with linguistic custom; for example, lower-case
121-685: The principle remains the same: the ripe fruits are shaken loose and collected in a net under the tree. The following cultivars are considered part of the Mirabelle cultivar group: The mirabelle is a speciality of the French region of Lorraine , which has an ideal climate and soil composition for the cultivation of this fruit. This region produces 15,000 tons of mirabelle plums annually, which constitutes 80% of global commercial production. There are two main cultivars grown for fruit production, derived from cherry plums grown in Nancy and Metz . The Metz type
