54-543: The Totapuri mango , or Ginimoothi , is a cultivar that is widely grown in south India and is partially cultivated in Sri Lanka . It also goes by the names Bangalore , Collector , Kallamai , Kili Mooku , Gilli , Mukku , "Ottu", and Sandersha . In Bengaluru it is referred to as Ginimoothi Maavina Kayi , while most of the rest of India calls it Totapuri or Bangalora . It literally translates to parrot face (gini = parrot, muthi = beak). Totapuri mango skin lacks
108-424: A "true" cultivar name – the recognized scientific name in the public domain – and a "commercial synonym" – an additional marketing name that is legally protected. An example would be Rosa Fascination = 'Poulmax', in which Rosa is the genus, Fascination is the trade designation, and 'Poulmax' is scientific cultivar name. Because a name that is attractive in one language may have less appeal in another country,
162-424: A component of a cultigen can be accepted as a cultivar if it is recognisable and has stable characters. Therefore, all cultivars are cultigens, because they are cultivated, but not all cultigens are cultivars, because some cultigens have not been formally distinguished and named as cultivars. The Cultivated Plant Code notes that the word cultivar is used in two different senses: first, as a "classification category"
216-436: A constant state of development which makes the naming of such an assemblage as a cultivar a futile exercise." However, retired transgenic varieties such as the fish tomato , which are no longer being developed, do not run into this obstacle and can be given a cultivar name. Cultivars may be selected because of a change in the ploidy level of a plant which may produce more desirable characteristics. Every unique cultivar has
270-541: A cultivar is a member of a species . The first edition of the ICNCP , which was agreed in 1952 in Wageningen and published in 1953, has been followed by seven subsequent editions – in 1958 ( Utrecht ), 1961 (update of 1958), 1969 ( Edinburgh ), 1980 ( Seattle ), 1995 ( Edinburgh ), 2004 ( Toronto ) and 2009 ( Wageningen ). The ninth (most recent) edition was published in 2016 ( Beijing ). William Stearn has outlined
324-796: A cultivar. Some cultivars "come true from seed", retaining their distinguishing characteristics when grown from seed. Such plants are termed a "variety", "selection", or "strain" but these are ambiguous and confusing words that are best avoided. In general, asexually propagated cultivars grown from seeds produce highly variable seedling plants, and should not be labelled with, or sold under, the parent cultivar's name. Seed-raised cultivars may be produced by uncontrolled pollination when characteristics that are distinct, uniform and stable are passed from parents to progeny. Some are produced as "lines" that are produced by repeated self-fertilization or inbreeding or "multilines" that are made up of several closely related lines. Sometimes they are F1 hybrids which are
378-802: A database of new cultivars protected by PBR in all countries. An International Cultivar Registration Authority (ICRA) is a voluntary, non-statutory organization appointed by the Commission for Nomenclature and Cultivar Registration of the International Society of Horticultural Science. ICRAs are generally formed by societies and institutions specializing in particular plant genera such as Dahlia or Rhododendron and are currently located in Europe, North America, China, India, Singapore, Australia, New Zealand, South Africa and Puerto Rico. Each ICRA produces an annual report and its reappointment
432-582: A modern vernacular language to distinguish them from botanical epithets. For example, the full cultivar name of the King Edward potato is Solanum tuberosum 'King Edward'. 'King Edward' is the cultivar epithet, which, according to the Rules of the Cultivated Plant Code , is bounded by single quotation marks. For patented or trademarked plant product lines developed from a given cultivar,
486-413: A name, the first letter of the word "Group" is itself capitalized. Since the 1990s there has been an increasing use of legal protection for newly produced cultivars. Plant breeders expect legal protection for the cultivars they produce. According to proponents of such protections, if other growers can immediately propagate and sell these cultivars as soon as they come on the market, the breeder's benefit
540-499: A particular disease. Genetically modified plants with characteristics resulting from the deliberate implantation of genetic material from a different germplasm may form a cultivar. However, the International Code of Nomenclature for Cultivated Plants notes, "In practice such an assemblage is often marketed from one or more lines or multilines that have been genetically modified. These lines or multilines often remain in
594-595: A particular part of the plant, such as a lateral branch, or from a particular phase of the life cycle, such as a juvenile leaf, or from aberrant growth as occurs with witch's broom . Plants whose distinctive characters are derived from the presence of an intracellular organism may also form a cultivar provided the characters are reproduced reliably from generation to generation. Plants of the same chimera (which have mutant tissues close to normal tissue) or graft-chimeras (which have vegetative tissue from different kinds of plants and which originate by grafting) may also constitute
SECTION 10
#1732791205968648-538: A plant may be given different selling names from country to country. Quoting the original cultivar name allows the correct identification of cultivars around the world. The main body coordinating plant breeders' rights is the International Union for the Protection of New Varieties of Plants ( Union internationale pour la protection des obtentions végétales , UPOV) and this organization maintains
702-462: A unique name within its denomination class (which is almost always the genus). Names of cultivars are regulated by the International Code of Nomenclature for Cultivated Plants , and may be registered with an International Cultivar Registration Authority (ICRA). There are sometimes separate registration authorities for different plant types such as roses and camellias. In addition, cultivars may be associated with commercial marketing names referred to in
756-709: A vernacular language. From circa the 1900s, cultivated plants in Europe were recognised in the Scandinavian, Germanic, and Slavic literature as stamm or sorte , but these words could not be used internationally because, by international agreement, any new denominations had to be in Latin. In the twentieth century an improved international nomenclature was proposed for cultivated plants. Liberty Hyde Bailey of Cornell University in New York , United States created
810-656: A white rose in 1958 as the cultivar 'KORbin'. This is sold in the United Kingdom under the selling name " Iceberg ", in France as " Fée des Neiges " and in Germany as " Schneewittchen ". Trade designations are not enclosed in single quotes. The ICNCP states that "trade designations must always be distinguished typographically from cultivar, Group and grex epithets." It uses small capitals for this purpose, thus Syringa vulgaris Ludwig Spaeth (trade designation)
864-409: Is capitalized (with some permitted exceptions such as conjunctions). It is permissible to place a cultivar epithet after a common name provided the common name is botanically unambiguous. Cultivar epithets published before 1 January 1959 were often given a Latin form and can be readily confused with the specific epithets in botanical names; after that date, newly coined cultivar epithets must be in
918-478: Is also known as Cultivated Plant Code . Cultigens under the purview of the ICNCP include cultivars , Groups ( cultivar groups ), and grexes . All organisms traditionally considered to be plants (including algae and fungi ) are included. Taxa that receive a name under the ICNCP will also be included within taxa named under the International Code of Nomenclature for algae, fungi, and plants , for example,
972-529: Is any plant that is deliberately selected for or altered in cultivation, as opposed to an indigen ; the Cultivated Plant Code states that cultigens are "maintained as recognisable entities solely by continued propagation". Cultigens can have names at any of many taxonomic ranks, including those of grex , species , cultivar group , variety , form , and cultivar; and they may be plants that have been altered in cultivation, including by genetic modification , but have not been formally denominated. A cultigen or
1026-444: Is considered every four years. The main task is to maintain a register of the names within the group of interest and where possible this is published and placed in the public domain. One major aim is to prevent the duplication of cultivar and Group epithets within a genus, as well as ensuring that names are in accord with the latest edition of the Cultivated Plant Code . In this way, over the last 50 years or so, ICRAs have contributed to
1080-404: Is largely lost. Legal protection for cultivars is obtained through the use of Plant breeders' rights and plant Patents but the specific legislation and procedures needed to take advantage of this protection vary from country to country. The use of legal protection for cultivars can be controversial, particularly for food crops that are staples in developing countries, or for plants selected from
1134-546: Is medium size with greenish yellow fruits. Cultivar A cultivar is a kind of cultivated plant that people have selected for desired traits and which retains those traits when propagated . Methods used to propagate cultivars include division, root and stem cuttings, offsets, grafting , tissue culture , or carefully controlled seed production. Most cultivars arise from deliberate human manipulation , but some originate from wild plants that have distinctive characteristics. Cultivar names are chosen according to rules of

#17327912059681188-432: Is simply a matter of convenience as the category was created to serve the practical needs of horticulture , agriculture , and forestry . Members of a particular cultivar are not necessarily genetically identical. The Cultivated Plant Code emphasizes that different cultivated plants may be accepted as different cultivars, even if they have the same genome, while cultivated plants with different genomes may be regarded as
1242-424: Is the sense of cultivar that is most generally understood and which is used as a general definition. A cultivar is an assemblage of plants that (a) has been selected for a particular character or combination of characters, (b) is distinct, uniform and stable in those characters, and (c) when propagated by appropriate means, retains those characters. Which plants are chosen to be named as cultivars
1296-440: Is to replace the Latin scientific names on plant labels in retail outlets with appealing marketing names that are easy to use, pronounce, and remember. Marketing names lie outside the scope of the Cultivated Plant Code which refers to them as "trade designations". If a retailer or wholesaler has the sole legal rights to a marketing name then that may offer a sales advantage. Plants protected by plant breeders' rights (PBR) may have
1350-543: The Lois de la Nomenclature botanique dealt with the names of plants of horticultural origin: Among cultivated plants, seedlings, crosses [ métis ] of uncertain origin and sports, receive fancy names in common language, as distinct as possible from the Latin names of species or varieties. When they can be traced back to a botanical species, subspecies or variety, this is indicated by a sequence of names (Pelargonium zonale Mistress-Pollock ). This Article survived redrafting of
1404-402: The Cultivated Plant Code as "trade designations" (see below). A cultivar name consists of a botanical name (of a genus, species , infraspecific taxon , interspecific hybrid or intergeneric hybrid) followed by a cultivar epithet . The cultivar epithet is enclosed by single quotes; it should not be italicized if the botanical name is italicized; and each of the words within the epithet
1458-417: The Cultivated Plant Code . Each ICRA also ensures that new names are formally established (i.e. published in hard copy, with a description in a dated publication). They record details about the plant, such as parentage, the names of those concerned with its development and introduction, and a basic description highlighting its distinctive characters. ICRAs are not responsible for assessing the distinctiveness of
1512-603: The ICNCP are prompted by international symposia for cultivated plant taxonomy which allow for rulings made by the International Commission on the Nomenclature of Cultivated Plants. Each new version includes a summary of the changes made to the previous version; the changes have also been summarised for the period 1953 to 1995. The ICNCP operates within the framework of the International Code of Nomenclature for algae, fungi, and plants which regulates
1566-500: The ICNCP refers to these as "trade designations". Only the cultivar name is governed by the ICNCP . It is required to be unique; in accordance with the principle of priority, it will be the first name that is published or that is registered by the discoverer or breeder of the cultivar. Trade designations are not regulated by the ICNCP ; they may be different in different countries. Thus the German rose breeder Reimer Kordes registered
1620-495: The International Code of Nomenclature for Cultivated Plants (ICNCP), and not all cultivated plants qualify as cultivars. Horticulturists generally believe the word cultivar was coined as a term meaning " cultivated variety ". Popular ornamental plants like roses , camellias , daffodils , rhododendrons , and azaleas are commonly cultivars produced by breeding and selection or as sports , for floral colour or size, plant form, or other desirable characteristics. Similarly,
1674-673: The International Rules of Botanical Nomenclature until 1935 and its core sentiments remain in the present-day ICNCP of 2009. The first version (1953) was published by the Royal Horticultural Society as a 29-page booklet, edited by William Stearn . Following the structure of the Botanical Code , the ICNCP is set out in the form of an initial set of Principles followed by Rules and Recommendations that are subdivided into Articles. Amendments to

1728-604: The Latin names in Linnaeus ' (1707–1778) Species Plantarum (tenth edition) and Genera Plantarum (fifth edition). In Species Plantarum , Linnaeus enumerated all plants known to him, either directly or from his extensive reading. He recognised the rank of varietas (botanical "variety", a rank below that of species and subspecies ) and he indicated these varieties with letters of the Greek alphabet , such as α, β, and λ, before
1782-514: The cultigen , which is defined as a plant whose origin or selection is primarily due to intentional human activity. A cultivar is not the same as a botanical variety , which is a taxonomic rank below subspecies , and there are differences in the rules for creating and using the names of botanical varieties and cultivars. In recent times, the naming of cultivars has been complicated by the use of statutory patents for plants and recognition of plant breeders' rights . The International Union for
1836-415: The etymology and it has been suggested that the word is actually a blend of culti gen and var iety . The neologism cultivar was promoted as "euphonious" and "free from ambiguity". The first Cultivated Plant Code of 1953 subsequently commended its use, and by 1960 it had achieved common international acceptance. The words cultigen and cultivar may be confused with each other. A cultigen
1890-546: The 1866 International Botanical Congress, where he suggested that future congresses should deal with nomenclatural matters. De Candolle, who had a legal background, drew up the Lois de la Nomenclature botanique (rules of botanical nomenclature). When adopted by the International Botanical Congress of Paris in 1867, this became the first version of today's International Code of Nomenclature for algae, fungi, and plants ( ICN ). Article 40 of
1944-457: The 1995 edition, it is still widely used and recommended by other authorities. Where several very similar cultivars exist they can be associated into a Group (formerly Cultivar-group ). As Group names are used with cultivar names it is necessary to understand their way of presentation. Group names are presented in normal type and the first letter of each word capitalised as for cultivars, but they are not placed in single quotes. When used in
1998-443: The Protection of New Varieties of Plants (UPOV – French : Union internationale pour la protection des obtentions végétales ) offers legal protection of plant cultivars to persons or organisations that introduce new cultivars to commerce. UPOV requires that a cultivar be "distinct", "uniform", and "stable". To be "distinct", it must have characters that easily distinguish it from any other known cultivar. To be "uniform" and "stable",
2052-473: The botanical variety except in respect to its origin. In that essay, Bailey used only the rank of species for the cultigen, but it was obvious to him that many domesticated plants were more like botanical varieties than species, and that realization appears to have motivated the suggestion of the new category of cultivar . Bailey created the word cultivar . It is generally assumed to be a blend of culti vated and var iety but Bailey never explicitly stated
2106-421: The commercial product name is typically indicated by the symbols "TM" or "®", or is presented in capital letters with no quotation marks, following the cultivar name, as in the following example, where "Bloomerang" is the commercial name and 'Penda' is the cultivar epithet: Syringa 'Penda' BLOOMERANG. Although "cv." has not been permitted by the International Code of Nomenclature for Cultivated Plants since
2160-496: The cultivar is defined in Article 2 of the International Code of Nomenclature for Cultivated Plants (2009, 8th edition) as follows: The basic category of cultivated plants whose nomenclature is governed by this Code is the cultivar. There are two other classification categories for cultigens, the grex and the group . The Code then defines a cultivar as a "taxonomic unit within the classification category of cultivar". This
2214-480: The cultivar must retain these characters in repeated propagation. The naming of cultivars is an important aspect of cultivated plant taxonomy , and the correct naming of a cultivar is prescribed by the Rules and Recommendations of the International Code of Nomenclature for Cultivated Plants (ICNCP, commonly denominated the Cultivated Plant Code ). A cultivar is given a cultivar name, which consists of

2268-545: The origins of ICNCP , tracing it back to the International Horticultural Congress of Brussels in 1864, when a letter from Alphonse de Candolle to Edouard Morren was tabled. This set out de Candolle's view that Latin names should be reserved for species and varieties found in the wild, with non-Latin or "fancy" names used for garden forms. Karl Koch supported this position at the 1865 International Botanical and Horticultural Congress and at

It
2376-428: The result of a deliberate repeatable single cross between two pure lines. A few F2 hybrid seed cultivars also exist, such as Achillea 'Summer Berries'. Some cultivars are agamospermous plants, which retain their genetic composition and characteristics under reproduction. Occasionally cultivars are raised from seed of a specially selected provenance – for example the seed may be taken from plants that are resistant to
2430-899: The same cultivar. The production of cultivars generally entails considerable human involvement although in a few cases it may be as little as simply selecting variation from plants growing in the wild (whether by collecting growing tissue to propagate from or by gathering seed). Cultivars generally occur as ornamentals and food crops: Malus ' Granny Smith ' and Malus ' Red Delicious ' are cultivars of apples propagated by cuttings or grafting , Lactuca 'Red Sails' and Lactuca 'Great Lakes' are lettuce cultivars propagated by seeds. Named cultivars of Hosta and Hemerocallis plants are cultivars produced by micropropagation or division. Cultivars that are produced asexually are genetically identical and known as clones ; this includes plants propagated by division , layering , cuttings , grafts , and budding . The propagating material may be taken from
2484-468: The scientific Latin botanical name followed by a cultivar epithet . The cultivar epithet is usually in a vernacular language. The word cultivar originated from the need to distinguish between wild plants and those with characteristics that arose in cultivation, presently denominated cultigens . This distinction dates to the Greek philosopher Theophrastus (370–285 BC), the "Father of Botany", who
2538-399: The scientific names of plants. The following are some examples of names governed by the ICNCP : Note that the ICNCP does not regulate trademarks for plants: trademarks are regulated by the law of the land involved. Nor does the ICNCP regulate the naming of plant varieties in the legal sense of that term. Many plants have "selling names" or "marketing names" as well as a cultivar name;
2592-479: The stability of cultivated plant nomenclature. In recent times many ICRAs have also recorded trade designations and trademarks used in labelling plant material, to avoid confusion with established names. New names and other relevant data are collected by and submitted to the ICRA and in most cases there is no cost. The ICRA then checks each new epithet to ensure that it has not been used before and that it conforms with
2646-456: The usual bitter taste of most mango skins or has a very slight bitterness and is consumed with the flesh traditionally. Totapuri was imported to Florida in 1901 as Sandersha and in the 1960s as Totapuri. It is the parent of at least two Florida mango cultivars, Anderson and Brooks . Totapuri is one of the main cultivars grown in India along with Alphonso , Dasheri, and Kesar mango . The tree
2700-432: The varietal name, rather than using the abbreviation "var." as is the present convention. Most of the varieties that Linnaeus enumerated were of "garden" origin rather than being wild plants. In time the need to distinguish between wild plants and those with variations that had been cultivated increased. In the nineteenth century many "garden-derived" plants were given horticultural names, sometimes in Latin and sometimes in
2754-428: The wild and propagated for sale without any additional breeding work; some people consider this practice unethical . The formal scientific name of a cultivar, like Solanum tuberosum 'King Edward', is a way of uniquely designating a particular kind of plant. This scientific name is in the public domain and cannot be legally protected. Plant retailers wish to maximize their share of the market and one way of doing this

#17327912059682808-414: The word cultivar in 1923 when he wrote that: The cultigen is a species, or its equivalent, that has appeared under domestication – the plant is cultigenous. I now propose another name, cultivar, for a botanical variety, or for a race subordinate to species, that has originated under cultivation; it is not necessarily, however, referable to a recognized botanical species. It is essentially the equivalent of
2862-406: The world's agricultural food crops are almost exclusively cultivars that have been selected for characters such as improved yield, flavour, and resistance to disease, and very few wild plants are now used as food sources. Trees used in forestry are also special selections grown for their enhanced quality and yield of timber . Cultivars form a major part of Liberty Hyde Bailey 's broader group,
2916-477: Was keenly aware of this difference. Botanical historian Alan Morton noted that Theophrastus in his Historia Plantarum ( Enquiry into Plants ) "had an inkling of the limits of culturally induced ( phenotypic ) changes and of the importance of genetic constitution" ( Historia Plantarum , Book 3, 2, 2 and Causa Plantarum , Book 1, 9, 3). The International Code of Nomenclature for algae, fungi, and plants uses as its starting point for modern botanical nomenclature
