In 1961 to 1962, Borlaug's dwarf spring wheat strains were sent for multilocation testing in the International Wheat Rust Nursery, organized by the U.S. Department of Agriculture. In March 1962, a few of these strains were grown in the fields of the Indian Agricultural Research Institute in Pusa, New Delhi, India.
Of wheat grown in the United States, 36% percent is consumed domestically by humans, 50% is exported, 10% is used for livestock feed, and 4% is used for seedlings. [16] Various American-style wheat beers are produced in the US. [17] Wheat in the U.S. is grown under two major categories based on climate: winter wheat, and spring wheat.
Ears of compact wheat. Modern wheat varieties have been selected for short stems, the result of RHt dwarfing genes [14] that reduce the plant's sensitivity to gibberellic acid, a plant hormone that lengthens cells. RHt genes were introduced to modern wheat varieties in the 1960s by Norman Borlaug from Norin 10 cultivars of wheat grown in Japan ...
A new genomic study, analyzing 827 varieties of wheat collected nearly a century ago, discovered a “goldmine” of genetic diversity that could help safeguard the crop well into the future.
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 second strategy is to hybridize wheat with T. intermedium to create a strain of wheat that mimics T. intermedium ' s resistance and perenniality but retains wheat's seed size and yield. In other words, this second strategy gives wheat more T. intermedium-like characteristics. Researchers hope that these two strategies will progress and meet ...
Triticum compactum or club wheat is a species of wheat adapted to low-humidity growing conditions. T. compactum is similar enough to common wheat (T. aestivum) that it is often considered a subspecies, T. aestivum compactum. It can be distinguished by its more compact ear due to shorter rachis segments, giving it its common name.
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 ...
