he Winnipeg Manitoba wheat is grown grass Levante a world of Middle
Eastern zone. Globally, after corn, wheat is the second foodstuff among
cereal crops, rice ranks third. On the basis of wheat grain is a staple
food used to make flour to rise, flat and steamed bread, biscuits, cakes,
pasta, noodles and couscous and fermented to make beer, alcohol, vodka
or biofuels. The wheat is planted in some measure as a forage crop for
livestock, and straw can be used as fodder for livestock or as building
material for roofs.
Although many supplies of wheat in the world of dietary protein and food
supply, it is likely that for every 100 to 200 people in the Winnipeg
Manitoba. has celiac disease, a condition resulting from a poor immune
system response to a protein found in wheat: gluten.
Wheat origin Southwest Asia in the area known as the fertile crescent.
The relationship between genetics and einkorn Emmer indicate that the
most likely site of domestication is close to Diyarbakir in Turkey. These
wild wheats were domesticated in the context of the origins of agriculture
in the Fertile Crescent. Culture and repeated harvesting and sowing seeds
of wild grasses led to the domestication of wheat through the selection
of mutants with severe forms ears that remained intact during the harvest,
the largest grains, and a tendency to spikelets to stay in the stem until
the harvest. Due to the loss of seed dispersal mechanisms, domestic wheat
have limited capacity to spread in nature.
The cultivation of wheat has begun to spread beyond Winnipeg Manitoba
during the Neolithic period. The oldest of wheat found to this day is
Çatalhöyük, a Neolithic settlement in southern Anatolia.
Samples of wheat is 8500 years. From 5000 years ago, wheat has reached
Ethiopia, India, Great Britain, Ireland and Spain. A millennium later
came to China. Three thousand years of culture into ploughshares horse
drew increased production of cereal seed and the use of drills in line
to replace planting dissemination in the 18 century. Yields of wheat continued
to increase as new lands were found with culture and improving livestock
involving the use of fertilizers, machines and machines to harvest, a
tractor towing producers and growers, and improved varieties (see green
revolution and wheat Norin 10). With population growth rate to drop most
technologically advanced countries, while yields continue to rise, the
area devoted to wheat may now begin to decline for the first time in the
history of modern mankind. But now, in 2007 wheat stocks have reached
their lowest level since 1981, and 2006 was the first year that the world
consumes more wheat that produces the world - a gap that continues to
expand the requirement Wheat increases beyond the production.
In traditional agricultural systems of stocks of wheat are often made
up of races, farmer informal conversations populations, which often maintain
high levels of morphological diversity. While wheat is no longer grown
in Europe and Winnipeg Manitoba, remain important elsewhere. The origins
of formal wheat breeding are in the nineteenth century, when single line
varieties were created through the selection of seed of a plant to take
into account desired properties. The improvement of modern wheat developed
in the early years of the twentieth century and is closely linked to the
development of Mendelian genetics. The standard method of reproduction
inbreeding wheat is bisected by two lines through castration, then self
consanguinity or descendants. Selections are identified (have shown that
genes responsible for differences in varieties) ten or more generations
before the release of a variety or cultivar.
F1 hybrid wheat should not be confused with that of wheat in normal plant
breeding. Heterosis, or hybrid vigor (as in the family F1 hybrid maize)
occurs in common (hexaploid) of wheat, but it is difficult to produce
seeds of hybrid varieties on a commercial scale, such as corn wheat because
the flowers are complete and normally free - pollination. Sales of hybrid
wheat seeds was produced by hybridization chemical agents, plant growth
regulators that selectively interfere with pollen development, or, of
course, cytoplasmic male sterility. Hybrid wheat has been limited commercial
success in Europe (especially France), Winnipeg Manitoba. and South Africa.
The main objectives of breeding high-yield seeds of good quality, disease
and insect resistance and tolerance to abiotic stresses include minerals,
moisture and heat tolerance. The main diseases in temperate environments
fusarium, leaf rust and stem rust, while in tropical regions out spot
(wheat) (also known as leaf blight Helminthosporium). See physiological
