After 1955 however, there was a ten-fold increase in the rate of wheat yield improvement per year, and this became the major factor allowing global wheat production to increase. Thus technological innovation and scientific crop management with synthetic nitrogen fertilizer , irrigation and wheat breeding were the main drivers of wheat output ...
Common wheat was first domesticated in West Asia during the early Holocene, and spread from there to North Africa, Europe and East Asia in the prehistoric period. [citation needed] Naked wheats (including Triticum aestivum, T. durum, and T. turgidum) were found in Roman burial sites ranging from 100 BCE to 300 CE.
The type and quantity vary between regions. The US is ranked fourth in production volume of wheat, with almost 50 million tons produced in 2020, behind only China, India and Russia. [2] The US is ranked first in crop export volume; almost 50% of its total wheat production is exported.
The following international wheat production statistics come from the Food and Agriculture Organization figures from FAOSTAT database, older from International Grains Council figures from the report "Grain Market Report". The quantities of wheat in the following table are in million metric tonnes. All countries with a typical production ...
A Vavilov center or center of origin is a geographical area where a group of organisms, either domesticated or wild, first developed its distinctive properties. [1] They are also considered centers of diversity. Centers of origin were first identified in 1924 by Nikolai Vavilov.
Genetic analysis has shown that the original hexaploid wheats were the result of a cross between a tetraploid domesticated wheat, such as T. dicoccum or T. durum, and a wild goatgrass, such as Ae. tauschii. [8] Polyploidy is important to wheat classification for three reasons: Wheats within one ploidy level will be more closely related to each ...
