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.
Norin 10 wheat (小麦農林10号) is a semi-dwarf wheat cultivar with very large ears that was bred by Gonjiro Inazuka at an experimental station in Iwate Prefecture, Japan. Its parents were a semi-dwarf Japanese landrace that may have originated in Korea in the 3rd or 4th century AD, and two varieties from the USA. [ 1 ]
Genetically modified wheat is wheat that has been genetically engineered by the direct manipulation of its genome using biotechnology. As of 2020, no genetically modified wheat is grown commercially, although many field tests have been conducted. One wheat variety, Bioceres HB4 Wheat, is obtaining regulatory approval from the government of ...
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 world population has grown by about five billion [88] since the beginning of the Green Revolution. India saw annual wheat production rise from 10 million tons in the 1960s to 73 million in 2006. [89] The average person in the developing world consumes roughly 25% more calories per day now than before the Green Revolution. [81]
Wheat is a group of wild and domesticated grasses of the genus Triticum (/ ˈ t r ɪ t ɪ k ə m /). [3] They are cultivated for their cereal grains, which are staple foods around the world. Well-known wheat species and hybrids include the most widely grown common wheat (T. aestivum), spelt, durum, emmer, einkorn, and Khorasan or Kamut.
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 ...
Einkorn is a short variety of wild wheat, usually less than 70 centimetres (28 in) tall and is not very productive of edible seeds. [5] The principal difference between wild einkorn and cultivated einkorn is the method of seed dispersal. In the wild variety the seed head usually shatters and drops the kernels (seeds) of wheat onto the ground. [1]
