Black Spanish (grape)
Black Spanish is a variation of grapes that were originally assumed to be a seedling of an American hybrid grape which resulted from the crossing of the American ''Vitis aestivalis'' species with a grape of an unknown ''Vitis vinifera'' pollen donor. Microsatellite DNA analysis (a.k.a. Simple Sequence Repeats or SSRs) has revealed that the American wild grapevine parent of Black Spanish (a.k.a. Jacquez) is '' Vitis berlandieri'' and not ''Vitis aestivalis''. This hybridization is not known to have been purposeful and may have occurred naturally, as was the case with many of the early American grape cultivars. Riaz et al. (2019) have now published the genetic profile of the Jacquez grapevine as follows (percentages): ''V. vinifera'': 69% ''V. berlandieri'': 21% ''V. rupestris'': 7% ''V. riparia'': 3%. Additional microsatellite DNA analyses was conducted on various 'Jacquez cultivars' by Dr. Jerry Rodrigues. They showed that at least two of the European accessions (grapevine collec ...

Vitis Aestivalis
''Vitis aestivalis'', the summer grape, or pigeon grape is a species of Vitis, grape native to eastern North America from southern Ontario east to Maine, west to Oklahoma, and south to Florida and Texas. It is a vigorous vine, growing to 10 m or more high in trees. The leaf, leaves are 7–20 cm long, suborbicular, and usually a little broader than long; they are variable in shape, from unlobed to deeply three- or five-lobed, green above, and densely hairy below. The flowers are produced at every 3rd node in a dense panicle 5–15 cm long. The fruit is a small grape 5–14 mm diameter, dark purple or black in colour.Oklahoma University''Vitis aestivalis''/ref> It is the official state grape of Missouri.http://www.moga.mo.gov/statutes/chapters/chap010.htm Summer grape prefers a drier upland habitat.

Vitis Vinifera
''Vitis vinifera'', the common grape vine, is a species of flowering plant, native to the Mediterranean region, Central Europe, and southwestern Asia, from Morocco and Portugal north to southern Germany and east to northern Iran. There are currently between 5,000 and 10,000 varieties of ''Vitis vinifera'' grapes though only a few are of commercial significance for wine and table grape production. The wild grape is often classified as ''Vitis vinifera'' ''sylvestris'' (in some classifications considered ''Vitis sylvestris''), with ''Vitis vinifera'' ''vinifera'' restricted to cultivated forms. Domesticated vines have hermaphrodite flowers, but ''sylvestris'' is dioecious (male and female flowers on separate plants) and pollination is required for fruit to develop. Grapes can be eaten fresh or dried to produce raisins, sultanas, and currants. Grape leaves are used in the cuisine of many cultures. The fresh grapes can also be processed into juice that is fermented to make wine ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vitis Berlandieri
''Vitis berlandieri'' is a species of grape native to the southern North America, primarily Texas, New Mexico and Arkansas. It is primarily known for good tolerance against soils with a high content of lime, which can cause chlorosis in many vines of American origin. Lime is a characteristic of the soils of many classical French wine regions and highly regarded vineyard sites, and many ''Vitis vinifera'' cultivars were well suited to these growing conditions. When American vines were imported to Europe as rootstocks for grafting ''V. vinifera'' on, in the wake of the Great French wine blight, it initially proved difficult to find vine species that would grow well in lime-rich soil. ''V. berlandieri'', which had adapted to limestone hills in central Texas, provided the lime tolerance needed to solve this problem. However, ''V. berlandieri'' itself is poorly adapted to grafting. Therefore, various rootstocks resistant against both phylloxera and lime, and suitable for viticulture, w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Phylloxera
Grape phylloxera is an insect pest of commercial grapevines worldwide, originally native to eastern North America. Grape phylloxera (''Daktulosphaira vitifoliae'' (Fitch 1855) belong to the family Phylloxeridae, within the order Hemiptera, bugs); originally described in France as ''Phylloxera vastatrix''; equated to the previously described ''Daktulosphaera vitifoliae'', ''Phylloxera vitifoliae''. The insect is commonly just called phylloxera (; from grc, φύλλον, leaf, and , dry). These almost microscopic, pale yellow sap-sucking insects, related to aphids, feed on the roots and leaves of grapevines (depending on the phylloxera genetic strain). On ''Vitis vinifera'', the resulting deformations on roots ("nodosities" and "tuberosities") and secondary fungal infections can girdle roots, gradually cutting off the flow of nutrients and water to the vine.Wine & Spirits Education Trust ''"Wine and Spirits: Understanding Wine Quality"'' pgs 2-5, Second Revised Edition (2012), Lo ...

Pierce's Disease
''Xylella fastidiosa'' is an aerobic, Gram-negative bacterium of the genus ''Xylella''. It is a plant pathogen, that grows in the water transport tissues of plants ( xylem vessels) and is transmitted exclusively by xylem sap-feeding insects such as sharpshooters and spittlebugs. Many plant diseases are due to infections of ''X. fastidiosa'', including bacterial leaf scorch, oleander leaf scorch, coffee leaf scorch (CLS), alfalfa dwarf, phony peach disease, and the economically important Pierce's disease of grapes (PD), olive quick decline syndrome (OQDS), and citrus variegated chlorosis (CVC). While the largest outbreaks of ''X. fastidiosa''–related diseases have occurred in the Americas and Europe, this pathogen has also been found in Taiwan, Israel, and a few other countries worldwide. ''Xylella fastidiosa'' can infect an extremely wide range of plants, many of which do not show any symptoms of disease. Disease occurs in plant species that are susceptible due to blockage ...

Texas Hill Country
The Texas Hill Country is a geographic region of Central and South Texas, forming the southeast part of the Edwards Plateau. Given its location, climate, terrain, and vegetation, the Hill Country can be considered the border between the American Southeast and Southwest. The region represents the very remote rural countryside of Central Texas, but also is home to growing suburban neighborhoods and affluent retirement communities. The region is notable for its karst topography and tall rugged hills of limestone or granite. Many of the hills rise to a height of above the surrounding plains and valleys, with Packsaddle Mountain rising to a height of above the Llano River in Kingsland. The Hill Country also includes the Llano Uplift and the second-largest granite dome in the United States, Enchanted Rock. The terrain throughout the region is characterized by a thin layer of topsoil and many exposed rocks and boulders, making the region very dry and prone to flash flooding. Nat ...

Rio Grande Valley (Texas)
The Lower Rio Grande Valley ( es, Valle del Río Grande), commonly known as the Rio Grande Valley or locally as the Valley or RGV, is a region spanning the border of Texas and Mexico located in a floodplain of the Rio Grande near its mouth. The region includes the southernmost tip of South Texas and a portion of northern Tamaulipas, Mexico. It consists of the Brownsville, Harlingen, Weslaco, Pharr, McAllen, Edinburg, Mission, San Juan, and Rio Grande City metropolitan areas in the United States and the Matamoros, Río Bravo, and Reynosa metropolitan areas in Mexico. The area is generally bilingual in English and Spanish, with a fair amount of Spanglish due to the region's diverse history and transborder agglomerations It is home to some of the poorest cities in the nation, as well as many unincorporated, persistent poverty communities called ''colonias''. A large seasonal influx occurs of "winter Texans" — people who come down from the north for the winter and then r ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vitis Labrusca
''Vitis labrusca'', the fox grape, is a species of grapevines belonging to the ''Vitis'' genus in the flowering plant family Vitaceae. The vines are native to eastern North America and are the source of many grape cultivars, including Catawba, Concord, Delaware, Isabella, Niagara, and many hybrid grape varieties such as Agawam, Alexander and Onaka. Among the characteristics of this vine species in contrast to the European wine grape ''Vitis vinifera'' are its "slip-skin" that allows the skin of the grape berries to easily slip off when squeezed, instead of crushing the pulp, and the presence of tendrils on every node of the cane. Another contrast with European ''vinifera'' is the characteristic "foxy" musk of ''V. labrusca'', best known to most people through the Concord grape. Jancis Robinson (ed.) ''The Oxford Companion to Wine'' (Oxford University Press, third edition 2006, ), pp 19-20 This musk is not related to the mammalian fox, but rather to the strong, earthy aromas char ...

Norton (grape)
Norton, is grown in the Midwestern United States, Mid-Atlantic States, northeastern Georgia. DNA data are consistent with 'Norton' being a hybrid with ancestry including ''V. aestivalis'' and ''V. vinifera''. Norton was first cultivated in Richmond, Virginia, and is the official grape of the State of Missouri, and is considered the cornerstone of the Missouri wine industry. Daniel Norton first purveyed the Norton cultivar during the early 19th century from his vineyards in Virginia, USA. History The Norton cultivar was introduced by Daniel Norborne Norton of Richmond, Virginia, who selected it from among what he believed were seedlings of a long forgotten grape variety called Bland, though there is some doubt as to whether it was the actual source of the seed which yielded Norton. The male parent, presumably, was a wild vine of ''Vitis aestivalis''. Another cultivar, called Cynthiana, closely resembles Norton, but has traditionally been considered a separate variety.

Blanc Du Bois
Blanc du Bois (French, ''white ''grapeof the woods ''forest') is an American hybrid grape that was created in 1968 by John A. Mortensen at the University of Florida’s Central Florida Research and Education Center in Leesburg, Florida. Mortensen created this variety by crossing various Vitis vinifera grape varieties such as Golden Muscat with native Florida varieties. When released in 1987, Blanc du Bois became another grape variety in the small but growing number of vine types that can both produce marketable wine on their own yet can withstand Pierce's Disease, a bacterial infection that destroys nearly all vinifera vinestocks imported into the southern United States. Despite the name, the grape variety has nothing to do with woods or forests; rather it was named in honor of Emile DuBois, an influential grapegrower and winemaker in the Tallahassee, Fla., area. Ancestry Blanc du Bois is two-thirds ''Vitis vinifera'', most of which is Cardinal. The rest is 25% ''V. smalliana'' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Texas Wine
Texas has a long history of wine production. The sunny and dry climate of the major winemaking regions in the state have drawn comparison to Portuguese wines, in addition to other regions in Europe like Spain, France, and Italy. Some of the earliest recorded Texas wines were produced by Spanish missionaries in the 1650s near El Paso. Texas ranked as the fifth largest wine producing state by 2019. The state is home to over 42 members of the ''Vitis'' grape vine family with fifteen being native to the state, more than any other region on earth. As of 2017, the state had over planted with ''Vitis vinifera''. Despite being the largest of conterminous states, this relatively small amount of planted land is dwarfed by the production of even the smallest French AOCs like Sancerre. The Texan wine industry is continuing its steady pace of expansion and has gained a reputation as an established wine growing region in the United States.
