Cultivars Of Tea Grown In China
A cultivar is a type of cultivated plant that people have selected for desired traits and when propagated retain those traits. Methods used to propagate cultivars include: division, root and stem cuttings, offsets, grafting, tissue culture, or carefully controlled seed production. Most cultivars arise from purposeful human manipulation, but some originate from wild plants that have distinctive characteristics. Cultivar names are chosen according to rules of the International Code of Nomenclature for Cultivated Plants (ICNCP), and not all cultivated plants qualify as cultivars. Horticulturists generally believe the word ''cultivar''''Cultivar'' () has two meanings, as explained in ''Formal definition'': it is a classification category and a taxonomic unit within the category. When referring to a taxon, the word does not apply to an individual plant but to all plants that share the unique characteristics that define the cultivar. was coined as a term meaning "cultivated variety ...

Sport (botany)
In botany, a sport or bud sport, traditionally called ''lusus'', is a part of a plant that shows morphological differences from the rest of the plant. Sports may differ by foliage shape or color, flowers, fruit, or branch structure. The cause is generally thought to be a chance genetic mutation. Sports with desirable characteristics are often propagated vegetatively to form new cultivars that retain the characteristics of the new morphology. Such selections are often prone to "reversion", meaning that part or all of the plant reverts to its original form. An example of a bud sport is the nectarine, at least some of which developed as a bud sport from peaches. Other common fruits resulting from a sport mutation are the red Anjou pear, the Ruby Red grapefruit, and the ' Pink Lemonade' lemon, which is a sport of the "Eureka" lemon. See also * Mosaic (genetics) Mosaicism or genetic mosaicism is a condition in multicellular organisms in which a single organism possesses more tha ...

Latin
Latin (, or , ) is a classical language belonging to the Italic branch of the Indo-European languages. Latin was originally a dialect spoken in the lower Tiber area (then known as Latium) around present-day Rome, but through the power of the Roman Republic it became the dominant language in the Italian region and subsequently throughout the Roman Empire. Even after the fall of Western Rome, Latin remained the common language of international communication, science, scholarship and academia in Europe until well into the 18th century, when other regional vernaculars (including its own descendants, the Romance languages) supplanted it in common academic and political usage, and it eventually became a dead language in the modern linguistic definition. Latin is a highly inflected language, with three distinct genders (masculine, feminine, and neuter), six or seven noun cases (nominative, accusative, genitive, dative, ablative, and vocative), five declensions, four verb conjuga ...

Cultivated Plant Taxonomy
Cultivated plant taxonomy is the study of the theory and practice of the science that identifies, describes, classifies, and names cultigens—those plants whose origin or selection is primarily due to intentional human activity. Cultivated plant taxonomists do, however, work with all kinds of plants in cultivation. Cultivated plant taxonomy is one part of the study of horticultural botany which is mostly carried out in botanical gardens, large nurseries, universities, or government departments. Areas of special interest for the cultivated plant taxonomist include: searching for and recording new plants suitable for cultivation ( plant hunting); communicating with and advising the general public on matters concerning the classification and nomenclature of cultivated plants and carrying out original research on these topics; describing the cultivated plants of particular regions (horticultural floras); maintaining databases, herbaria and other information about cultivated plant ...

International Union For The Protection Of New Varieties Of Plants
The International Union for the Protection of New Varieties of Plants or UPOV (french: link=no, Union internationale pour la protection des obtentions végétales) is a treaty body (non-United Nations intergovernmental organization) with headquarters in Geneva, Switzerland. Its objective is to provide an effective system for plant variety protection. It does so by defining a blueprint regulation to be implemented by its members in national law. The expression UPOV Convention also refers to one of the three instruments that relate to the union, namely the ''1991 Act of the UPOV Convention'' (UPOV 91), ''1978 Act of the UPOV Convention'' (UPOV 78) and ''1961 Act of the UPOV Convention with Amendments of 1972'' (UPOV 61). History UPOV was established by the International Convention for the Protection of New Varieties of Plants (UPOV 61). The convention was adopted in Paris in 1961 and revised in 1972, 1978 and 1991. The initiative for the foundation of UPOV came from European bre ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Plant Breeders' Rights
Plant breeders' rights (PBR), also known as plant variety rights (PVR), are rights granted to the breeder of a new variety of plant that give the breeder exclusive control over the propagating material (including seed, cuttings, divisions, tissue culture) and harvested material (cut flowers, fruit, foliage) of a new variety for a number of years. With these rights, the breeder can choose to become the exclusive marketer of the variety, or to license the variety to others. In order to qualify for these exclusive rights, a variety must be new, distinct, uniform, and stable. A variety is: *''new'' if it has not been commercialized for more than one year in the country of protection; *''distinct'' if it differs from all other known varieties by one or more important botanical characteristics, such as height, maturity, color, etc.; *''uniform'' if the plant characteristics are consistent from plant to plant within the variety; *''stable'' if the plant characteristics are genetically fi ...
