Désirée Potato
The Désirée potato (sometimes rendered Desirée or Desiree) is a red-skinned ''main-crop'' potato originally bred in the Netherlands in 1962. It has yellow flesh with a distinctive flavour and is a favourite with allotment-holders because of its resistance to drought, and is fairly resistant to disease. It is a versatile, fairly waxy variety which is firm and holds its shape, and is useful for all methods of cooking, from roasting to mashing and salads. It is immune to potato wart and it is resistant to skin spot. It has good resistance to PVY, tuber late blight and blackleg. It also has moderate resistance to PVA, PVX and fusarium dry rot ''Fusarium'' dry rot is one of the most common potato diseases. It is caused by fungi in the genus ''Fusarium''. This fungi causes a variety of colored rots in potatoes. This pathogen, while having both a sexual and asexual form, stays in an asexual .... It is found to be moderately susceptible to leaf late blight and leaf roll, also it ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Potato
The potato is a starchy food, a tuber of the plant ''Solanum tuberosum'' and is a root vegetable native to the Americas. The plant is a perennial in the nightshade family Solanaceae. Wild potato species can be found from the southern United States to southern Chile. The potato was originally believed to have been domesticated by Native Americans independently in multiple locations,University of Wisconsin-Madison, ''Finding rewrites the evolutionary history of the origin of potatoes'' (2005/ref> but later genetic studies traced a single origin, in the area of present-day southern Peru and extreme northwestern Bolivia. Potatoes were domesticated there approximately 7,000–10,000 years ago, from a species in the ''Solanum brevicaule'' complex. Lay summary: In the Andes region of South America, where the species is indigenous, some close relatives of the potato are cultivated. Potatoes were introduced to Europe from the Americas by the Spanish in the second half of the 16 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Solanum
''Solanum'' is a large and diverse genus of flowering plants, which include three food crops of high economic importance: the potato, the tomato and the eggplant (aubergine, brinjal). It is the largest genus in the nightshade family Solanaceae, comprising around 1,500 species. It also contains the so-called horse nettles (unrelated to the genus of true nettles, ''Urtica''), as well as numerous plants cultivated for their ornamental flowers and fruit. ''Solanum'' species show a wide range of growth habits, such as annuals and perennials, vines, subshrubs, shrubs, and small trees. Many formerly independent genera like '' Lycopersicon'' (the tomatoes) and ''Cyphomandra'' are now included in ''Solanum'' as subgenera or sections. Thus, the genus today contains roughly 1,500–2,000 species. Name The generic name was first used by Pliny the Elder (AD 23–79) for a plant also known as , most likely ''S. nigrum''. Its derivation is uncertain, possibly stemming from the Latin word ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Allotment (gardening)
An allotment (British English), or in North America, a community garden, is a plot of land made available for individual, non-commercial gardening or growing food plants, so forming a kitchen garden away from the residence of the user. Such plots are formed by subdividing a piece of land into a few or up to several hundred parcels that are assigned to individuals or families. Such parcels are cultivated individually, contrary to other community garden types where the entire area is tended collectively by a group of people. In countries that do not use the term "allotment (garden)", a "community garden" may refer to individual small garden plots as well as to a single, large piece of land gardened collectively by a group of people. The term "victory garden" is also still sometimes used, especially when a community garden dates back to the First or Second World War. The individual size of a parcel typically suits the needs of a family, and often the plots include a shed for tools a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Potato Virus Y
Potato virus Y (PVY) is a plant pathogenic virus of the family ''Potyviridae'', and one of the most important plant viruses affecting potato production. PVY infection of potato plants results in a variety of symptoms depending on the viral strain. The mildest of these symptoms is production loss, but the most detrimental is 'potato tuber necrotic ringspot disease' (PTNRD). Necrotic ringspots render potatoes unmarketable and can therefore result in a significant loss of income. PVY is transmissible by aphid vectors but may also remain dormant in seed potatoes. This means that using the same line of potato for production of seed potatoes for several consecutive generations will lead to a progressive increase in viral load and subsequent loss of crop. An increase in potato plant infection with viruses over the past few years has led to considerable losses to the South African potato industry. The increased rate of infection may be attributed to several factors. These include a mar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Potato Blight
''Phytophthora infestans'' is an oomycete or water mold, a fungus-like microorganism that causes the serious potato and tomato disease known as late blight or potato blight. Early blight, caused by ''Alternaria solani'', is also often called "potato blight". Late blight was a major culprit in the 1840s European, the 1845–1852 Irish, and the 1846 Highland potato famines. The organism can also infect some other members of the Solanaceae. The pathogen is favored by moist, cool environments: sporulation is optimal at in water-saturated or nearly saturated environments, and zoospore production is favored at temperatures below . Lesion growth rates are typically optimal at a slightly warmer temperature range of . Etymology The genus name ''Phytophthora'' comes from the Greek –(), meaning : "plant" – plus the Greek (), meaning : "decay, ruin, perish". The species name ''infestans'' is the present participle of the Latin verb , meaning : "attacking, destroying", from which w ...

Blackleg (potatoes)
Blackleg is a plant disease of potato caused by pectolytic bacteria that can result in stunting, wilting, chlorosis of leaves, necrosis of several tissues, a decline in yield, and at times the death of the potato plant. The term "blackleg" originates from the typical blackening and decay of the lower stem portion, or "leg", of the plant.De Boer S. H. 2004"Blackleg of potato" The Plant Health Instructor. DOI:10.1094/PHI-I-2004-0712-01 Blackleg in potatoes is most commonly caused by '' Pectobacterium atrosepticum'' (older synonym: ''Erwinia carotovora subsp. astroseptica''), a gram-negative, nonsporulating, facultative anaerobe that is also associated with soft rot of potatoes. While other bacterial species such as ''Pectobacterium carotovorum'' and ''Dickeya dadantii'' can exhibit symptoms similar to blackleg of potato, these pathogens exhibit broader host ranges, are present in different climates, and typically are more associated with soft rot diseases.Ali HF, Ahmad M, Junaid ...

Potato Virus X
Potato virus X (PVX) is a plant pathogenic virus of the family ''Alphaflexiviridae'' and the order ''Tymovirales''. PVX is found mainly in potatoes and is only transmitted mechanically. There are no insect or fungal vectors for this virus. This virus causes mild or no symptoms in most potato varieties, but when Potato virus Y is present, synergy between these two viruses causes severe symptoms in potatoes. The virion has helical symmetry and a deeply grooved, highly hydrated surface and is made of a single-stranded positive-sense RNA genome of approximately 6.4 kb. This is wrapped in approximately 1300 units of a single coat protein (CP) type, with 8.9 CP units per helix turn. The genome is capped at the 5′-end and poly-adenylated at the 3′-terminus. It contains five open reading frames (ORFs) encoding five proteins: the RNA-dependent RNA Polymerase (RdRP), the movement proteins encoded by three overlapping ORFs that form the Triple Gene Block module (TGBp1, TGBp2, and TGBp3), ...

Fusarium Dry Rot
''Fusarium'' dry rot is one of the most common potato diseases. It is caused by fungi in the genus ''Fusarium''. This fungi causes a variety of colored rots in potatoes. This pathogen, while having both a sexual and asexual form, stays in an asexual cycle due to the way it spreads. Preferring warmer climates, it is not uncommon to find this pathogen in the northern United States where it has been reported to affect yield as much as 60%. Hosts and symptoms ''Fusarium'' dry rot of potato is a devastating post-harvest losses (vegetables) disease affecting both seed potatoes and potatoes for human consumption.Rowe, R.C., Miller, S.A, & Riedel R.M. ''Fusarium'' Dry Rot and Seed Piece Decay of Potato. Retrieved from http://www.oardc.ohio-state.edu/sallymiller/extension/factsheets/fuspotato.pdf Dry rot causes the skin of the tuber to wrinkle. The rotted areas of the potato may be brown, grey, or black and the rot creates depressions in the surface of the tuber. Seed pieces may rot complet ...

Potato Leafroll Virus
Potato leafroll virus (PLRV) is a member of the genus ''Polerovirus'' and family ''Solemoviridae''. The phloem limited positive sense RNA virus infects potatoes and other members of the family Solanaceae. PLRV was first described by Quanjer ''et al.'' in 1916. PLRV is transmitted by aphids, primarily the green peach aphid, ''Myzus persicae''. PLRV is one of the most important potato viruses worldwide but particularly devastating in countries with limited resources and management. It can be responsible for individual plant yield losses of over 50%. One estimate suggests that PLRV is responsible for an annual global yield loss of 20 million tons. Symptoms include chlorosis, necrosis and leaf curling. Hosts and symptoms PLRV infects members of the family Solanaceae. The most economically important host is the Potato, ''Solanum tuberosum'' spp. In potato, symptoms of primary infection, infection in the growing season, occurs in the youngest leaves. Leaf margins become necrotic, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
