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 ''Hemileia vastatrix'' is a multicellular Basidiomycota, basidiomycete fungus of the order Pucciniales (previously also known as Uredinales) that causes coffee leaf rust (CLR), a disease affecting the Coffea, coffee plant. Coffee serves as t ... (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. It represents 25-30% of the acreage o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Coffea
''Coffea'' is a genus of flowering plants in the family Rubiaceae. ''Coffea'' species are shrubs or small trees native to tropical and southern Africa and tropical Asia. The seeds of some species, called coffee beans, are used to flavor various beverages and products. The fruits, like the seeds, contain a large amount of caffeine, and have a distinct sweet taste. The plant ranks as one of the world's most valuable and widely traded commodity crops and is an important export product of several countries, including those in Central and South America, the Caribbean and Africa. The coffee trade relies heavily on two of the over 120 species, ''Coffea arabica'' (commonly known simply as "Arabica"), which accounts for 60–80% of the world's coffee production, and ''Coffea canephora'' (known as " Robusta"), which accounts for about 20–40%. Both coffee species are vulnerable to shifts, caused by climate change, in their growing zones, which are likely to result in a decline in pr ...

Coffea Arabica
''Coffea arabica'' (), also known as the Arabica 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 the dominant cultivar, representing about 60% of global production. Coffee produced from the less acidic, more bitter, and more highly caffeinated robusta bean (''Coffea canephora, C. canephora'') makes up most of the remaining coffee production. The natural populations of ''Coffea arabica'' are restricted to the forests of South Ethiopia and Yemen. Taxonomy ''Coffea arabica'' was first species description, described scientifically by Antoine de Jussieu, who named it ''Jasminum arabicum'' after studying a specimen from the Hortus Botanicus (Amsterdam), Botanic Gardens of Amsterdam. Carl Linnaeus, Linnaeus placed it in its own genus ''Coffea'' in 1737. ''Coffea arabica'' is one of the polyploid species of the genus ''Coffea'', as it carries four copies of the eleven ch ...

Cultivar
A cultivar is a kind of Horticulture, cultivated plant that people have selected for desired phenotypic trait, traits and which retains those traits when Plant propagation, propagated. Methods used to propagate cultivars include division, root and stem cuttings, offsets, grafting, micropropagation, tissue culture, or carefully controlled seed production. Most cultivars arise from deliberate human genetic engineering, 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, 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 t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 leaves 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, whi ...

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 areas including Colombia, Venezuela, the Philippines, Borneo and Java. 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. Characteristics ''Coffea liberica'' beans are larger than Arabica and Robusta beans, with a unique shape ... [...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-qua ...

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] |
