Heterosis or hybrid vigor (as in the familiar F1 hybrids of maize) occurs in common (hexaploid) wheat, but it is difficult to produce seed of hybrid cultivars on a commercial scale as is done with maize because wheat flowers are perfect in the botanical sense, meaning they have both male and female parts, and normally self-pollinate. }); { bidder: 'openx', params: { unit: '539971081', delDomain: 'idm-d.openx.net' }}, [88] Supplementation with proteins from other food sources (mainly legumes) is commonly used to compensate for this deficiency,[13] since the limitation of a single essential amino acid causes the others to break down and become excreted, which is especially important during the period of growth. { bidder: 'triplelift', params: { inventoryCode: 'Cambridge_SR' }}, { bidder: 'ix', params: { siteId: '195465', size: [300, 250] }}, bidders: '*', { bidder: 'sovrn', params: { tagid: '346693' }}, [17] Selection for these traits by farmers might not have been deliberately intended, but simply have occurred because these traits made gathering the seeds easier; nevertheless such 'incidental' selection was an important part of crop domestication. bids: [{ bidder: 'rubicon', params: { accountId: '17282', siteId: '162036', zoneId: '776160', position: 'atf' }}, name: "pbjs-unifiedid", { bidder: 'criteo', params: { networkId: 7100, publisherSubId: 'cdo_rightslot' }}, { bidder: 'sovrn', params: { tagid: '346688' }}, { bidder: 'ix', params: { siteId: '195451', size: [300, 250] }}, These remains were dated by Willem van Zeist and his assistant Johanna Bakker-Heeres to 8800 BCE. wheat definition: 1. a plant whose yellowish-brown grain is used for making flour, or the grain itself: 2. a plant….

Various studies in India, for example, have concluded that about 10% of total wheat production is lost at farm level, another 10% is lost because of poor storage and road networks, and additional amounts lost at the retail level. 'Lodging' occurs when an ear stalk falls over in the wind and rots on the ground, and heavy nitrogenous fertilization of wheat makes the grass grow taller and become more susceptible to this problem. In recent years, low international wheat prices have often encouraged farmers in the United States to change to more profitable crops.

Wild emmer is itself the result of a hybridization between two diploid wild grasses, T. urartu and a wild goatgrass such as Aegilops searsii or Ae. The major diseases in temperate environments include the following, arranged in a rough order of their significance from cooler to warmer climates: eyespot, Stagonospora nodorum blotch (also known as glume blotch), yellow or stripe rust, powdery mildew, Septoria tritici blotch (sometimes known as leaf blotch), brown or leaf rust, Fusarium head blight, tan spot and stem rust. }, dfpSlots['topslot_b'] = googletag.defineSlot('/2863368/topslot', [[728, 90]], 'ad_topslot_b').defineSizeMapping(mapping_topslot_b).setTargeting('sri', '0').setTargeting('vp', 'top').setTargeting('hp', 'center').addService(googletag.pubads()); { bidder: 'appnexus', params: { placementId: '11654174' }}, { bidder: 'triplelift', params: { inventoryCode: 'Cambridge_HDX' }}, Definition and synonyms of wheat from the online English dictionary from Macmillan Education.

Improved agricultural husbandry has more recently included threshing machines, reaper-binder machines (the 'combine harvester'), tractor-drawn cultivators and planters, and better varieties (see Green Revolution and Norin 10 wheat). The varieties of wheat created through these methods are in the hundreds (going as far back as 1960), more of them being created in higher populated countries such as China.

[119], In the 20th century, global wheat output expanded by about 5-fold, but until about 1955 most of this reflected increases in wheat crop area, with lesser (about 20%) increases in crop yields per unit area.

Most breads are made with wheat flour, including many breads named for the other grains they contain, for example, most rye and oat breads.
