S795 Coffee
S795 (Selection-795) is a coffee cultivar important for being one of the first strains of '' C. arabica'' found to be resistant to coffee leaf rust (CLR). It is a selection of the Balehonnur Coffee Research Station in India and it was generated by R.L. Narasimhaswamy by cross breeding '' C. arabica'' and '' C. liberica'' known as S288 and the Kent variety, a hybrid of Typica and an unknown other type. Both S288 and Kent are known to be resistant to many rust races and the Kent variety is a high-yielding tree. The resultant S795 cultivar exhibits rust resistance, high yield, and a good cup profile, making it a desirable cultivar for producers. S795 is widely planted in India and Indonesia. In India, it represents 25-30% of the acreage of arabica coffee. Description S795 is a tall and vigorous shrub producing a high number of primary and secondary plagiotropic branches. The fruit (cherries) are medium in size and oblong in shape and progress from green when young to dark re ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cultivar
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 ...

Coffea Arabica
''Coffea arabica'' (), also known as the Arabic coffee, is a species of flowering plant in the coffee and madder family Rubiaceae. It is believed to be the first species of coffee to have been cultivated and is currently the dominant cultivar, representing about 60% of global production. Coffee produced from the less acidic, more bitter, and more highly caffeinated robusta bean ('' C. canephora'') makes up most of the remaining coffee production. Arabica coffee originates from and was first cultivated in Yemen, and documented by the 12th century. ''Coffea arabica'' is called () in Arabic, borrowed from the Amharic "Buna". Taxonomy ''Coffea arabica'' was first described scientifically by Antoine de Jussieu, who named it ''Jasminum arabicum'' after studying a specimen from the Botanic Gardens of Amsterdam. Linnaeus placed it in its own genus ''Coffea'' in 1737. ''Coffea arabica'' is the only polyploid species of the genus ''Coffea,'' as it carries 4 copies of the 11 chromosom ...

Hemileia Vastatrix
''Hemileia vastatrix'' is a multicellular basidiomycete fungus of the order Pucciniales (previously also known as Uredinales) that causes coffee leaf rust (CLR), a disease affecting the coffee plant. Coffee serves as the obligate host of coffee rust, that is, the rust must have access to and come into physical contact with coffee (''Coffea sp.'') in order to survive. CLR is one of the most economically important diseases of coffee, worldwide. Previous epidemics have destroyed coffee production of entire countries. In more recent history, an epidemic in Central America in 2012 reduced the region's coffee output by 16%. The primary pathological mechanism of the fungus is a reduction in the plant's ability to derive energy through photosynthesis by covering the leafs with fungus spores and/or causing leaves to drop from the plant. The reduction in photosynthetic ability (plant's metabolism) results in a reduction in quantity and quality of flower and fruit production, which ult ...

Coffea Liberica
''Coffea liberica'', commonly known as the Liberian coffee, is a species of flowering plant in the family Rubiaceae from which coffee is produced. It is native to western and central Africa from Liberia to Uganda and Angola, and has become naturalised in the Philippines, Indonesia, Seychelles, the Andaman & Nicobar Islands, and Malaysia. Description ''Coffea liberica'' trees are very tall, reaching up to high. They are harvested using ladders. The size of the cherries, the beans, and the leaves of barako are also among the largest of all coffee varieties. The shape of the ''liberica'' beans is unique among other commercial species ('' arabica'', ''robusta'') and varieties (''liberica'' var. ''dewevrei''). It is asymmetric, with one side shorter than the other side, creating characteristic "hook" at the tip. The central furrow is also more jagged in comparison to other coffee beans. Cultivation and use ''Coffea liberica'' accounts for less than 1.5% of commercial coffee grow ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cup Of Excellence
The Cup of Excellence is an annual competition held in several countries to identify the highest quality coffees produced. It is organized by the Alliance for Coffee Excellence, which was founded by George Howell, Susie Spindler and Silvio Leite. The Cup of Excellence has worked to fundamentally change the high quality coffee industry and has supported advances in farming and premiums to farmers that would have been impossible without it. Format The winning coffees are sold in internet auctions. The concept was developed by the Gourmet Coffee Project of the International Coffee Organization (ICO). This project was devised by Pablo Dubois, Head of Operations of the ICO and Frans Bolvenkel, of the International Trade Centre (ITC) at a meeting in Geneva in late 1994. This project, supervised by the ICO, managed by the ITC and largely financed by the Common Fund for Commodities, ran from 1995 to 2000, and aimed to develop methodologies for the creation of new "gourmet" or high-q ...

List Of Coffee Varieties
] Coffee varieties are the diverse subspecies derived through selective breeding or natural selection of coffee plants. While there is tremendous variability encountered in both wild and cultivated coffee plants, there are a few varieties and cultivars that are commercially important due to various unique and inherent traits such as disease resistance and fruit yield. These unique traits are what producers use to select breeds when developing crops. Therefore, at a micro level, breed selection is critical to the success of a producer and is one of the key components of cup quality. At a macro level, the viability of the coffee industry as a whole is dependent upon breed selection. Already, the majority of coffee produced originates from producers using selected breeds. For this reason, breed selection is an important aspect of sustainability within coffee production. Terminology There is considerable confusion as to which term to use when speaking about coffee subspecies. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Lists Of Cultivars
__NOTOC__ The lists of cultivars in the table below are indices of plant cultivars, Plant variety (law), varieties, and Strain (biology), strains. A ''cultivar'' is a plant that is Artificial selection, selected for desirable characteristics that can be maintained by Plant propagation, propagation. The plants listed may be Ornamental plant, ornamental, Medicinal plant, medicinal, and/or Eating, edible. Several of them bear edible fruit. Plants are Selective breeding, selectively bred for phenotypic traits (such as flower colour) and other hereditary traits. When developing a new variety, a plant breeder might value such characteristics as appearance, Disease resistance in fruit and vegetables, disease resistance, and Hardiness (plants), hardiness. In the cultivation of edible fruit and vegetables, nutritional value, shelf life, and crop yield are also among the potential considerations. Some of the lists use the word ''variety'' instead of ''cultivar''. In most of these lists, ''v ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
