MegaChip Computers
MegaChip is a round white potato variety with good tuber size,Paul R. Wonning and specific gravity for making potato chips. It was developed at Rhinelander Agricultural Research Station in Wisconsin and it was result of a cross between 'Wischip' and 'FYF85' after many years of selection and breeding.Groza, H. I. "Megachip: A new potato variety for chipping". ''American Potato Journal'' 84: 343-349 The cross resulting in Megachip was made in 1985. It produces high quality chips that have an excellent color both from the field and after storage at 7.2 to 10 degrees C. Botanical features * Medium-late variety for chipping * Round-oval tubers with medium to large size * Flesh is white and have a high specific gravity, and medium-long dormancy * Leaves are dark green * Has four to seven inflorescences per plant * 12 florets per inflorescence, and medium peduncle length Agricultural feature * High level of resistance to common scab * Moderately resistant to foliar early blight, p ...

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] |

Tuber
Tubers are a type of enlarged structure used as storage organs for nutrients in some plants. They are used for the plant's perennation (survival of the winter or dry months), to provide energy and nutrients for regrowth during the next growing season, and as a means of asexual reproduction. ''Stem tubers'' form thickened rhizomes (underground stems) or stolons (horizontal connections between organisms); well known species with stem tubers include the potato and yam. Some writers also treat modified lateral roots (''root tubers'') under the definition; these are found in sweet potatoes, cassava, and dahlias. Terminology The term originates from the Latin , meaning "lump, bump, swelling". Some writers define the term "tuber" to mean only structures derived from stems; others use the term for structures derived from stems or roots., p. 124 Stem tubers A stem tuber forms from thickened rhizomes or stolons. The top sides of the tuber produce shoots that grow into typical stems ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Potato Chip
A potato chip (North American English; often just chip) or crisp (British and Irish English) is a thin slice of potato that has been either deep fried, baked, or air fried until crunchy. They are commonly served as a snack, side dish, or appetizer. The basic chips are cooked and salted; additional varieties are manufactured using various flavorings and ingredients including herbs, spices, cheeses, other natural flavors, artificial flavors, and additives. Potato chips form a large part of the snack food and convenience food market in Western countries. The global potato chip market generated total revenue of US$16.49 billion in 2005. This accounted for 35.5% of the total savory snacks market in that year ($46.1 billion). History The earliest known recipe for something similar to today's potato chips is in William Kitchiner's book '' The Cook's Oracle'' published in 1817, which was a bestseller in the United Kingdom and the United States. The 1822 edition's recipe for "Pota ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Powdery Scab
Powdery scab is a disease of potato tubers. It is caused by the cercozoan ''Spongospora subterranea'' f. sp. ''subterranea'' and is widespread in potato growing countries. Symptoms of powdery scab include small lesions in the early stages of the disease, progressing to raised pustules containing a powdery mass. These can eventually rupture within the tuber periderm.Maldonado, M. Loreto Hernandez, Richard E. Falloon, Ruth C. Butler, Anthony J. Conner, and Simon R. Bulman. "''Resistance to Spongospora Subterranea Induced in Potato by the Elicitor β-aminobutyric Acid.''" Australasian Plant Pathol. Australasian Plant Pathology 44.4 (2015): 445-53. Web. 21 Oct. 2015. The powdery pustules contain resting spores that release anisokont zoospores (asexual spore with two unequal length flagella) to infect the root hairs of potatoes or tomatoes. Powdery scab is a cosmetic defect on tubers, which can result in the rejection of these potatoes. Potatoes which have been infected can be peeled t ...

Phytophthora Erythroseptica
''Phytophthora erythroseptica''—also known as pink rot along with several other species of ''Phytophthora''—is a plant pathogen. It infects potatoes (''Solanum tuberosum'') causing their tubers to turn pink and damages leaves. It also infects tulips (''Tulipa'') damaging their leaves and shoots. Several species from the genus ''Phytophthora'' are believed to be involved in causing pink rot-like diseases. Disease cycle As ''Phytophthora erythroseptica'' is an oomycete, its disease cycle follows that of similar ''Phytophthora'' species. Oospores, sporangia, and zoospores can infect any part of the potato plant that is below ground. Oospores serve as the primary form of inoculum, and can survive in the soil as long as seven yearsWarton, Phillip., Kirk, William. Potato Diseases: Pink Rot (E2993). 31 January 2017. Michigan State University Extension http://msue.anr.msu.edu/resources/potato_diseases_pink_rot_e2993 Oospores produced in the field can overwinter and when thaw ...

Dry Rot
Dry rot is wood decay caused by one of several species of fungi that digest parts of the wood which give the wood strength and stiffness. It was previously used to describe any decay of cured wood in ships and buildings by a fungus which resulted in a darkly colored deteriorated and cracked condition. The life-cycle of dry rot can be broken down into four main stages. Dry rot begins as a microscopic spore which, in high enough concentrations, can resemble a fine orange dust. If the spores are subjected to sufficient moisture, they will germinate and begin to grow fine white strands known as hyphae. As the hyphae grow they will eventually form a large mass known as mycelium. The final stage is a fruiting body which pumps new spores out into the surrounding air. In other fields, the term has been applied to the decay of crop plants by fungi. In health and safety, the term is used to describe the deterioration of rubber, for example the cracking of rubber hoses. Discussion '' ...

Erwinia
''Erwinia'' is a genus of Enterobacterales bacteria containing mostly plant pathogenic species which was named for the famous plant pathologist, Erwin Frink Smith. It contains Gram-negative bacteria related to ''Escherichia coli'', ''Shigella'', ''Salmonella'', and ''Yersinia''. They are primarily rod-shaped bacteria. Many infect woody plants. A well-known member of this genus is the species '' E. amylovora'', which causes fire blight on apples, pears, and other Rosaceae crops; ''E. tracheiphila'', though, causes bacterial wilt of cucurbits. Other familiar species, such as '' E. carotovora'' (another major cause of plant diseases), are more distantly related to the fire blight bacterium, and have been moved to genera ''Brenneria'', ''Dickeya'', and '' Pectobacterium''. ''Erwinia aphidocola'' and ''E. persicina'' species were both observed to be present within the floral nectar microbial community of seven different orchid (''Epipactis'') flower species. ''E. aphidicola'' appear ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
