Norin 10
is a semi-dwarf wheat cultivar with very large ears that was bred by 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. In 1935 it was registered as a numbered cultivar by the Japanese Ministry of Agriculture and Forestry . Norin 10 grew to just two feet (60 - 100 cm) tall, instead of the usual four (150 cm). It provided two genes, ''Rht1'' and ''Rht2'', that resulted in reduced-height wheats, thus allowing better nutrient uptake and tillage, since when heavily fertilised with nitrogen, tall varieties grow too high, become top-heavy, and lodge. The ''Rht1'' and ''Rht2'' genes have been used in wheat breeding programmes worldwide to provide shorter plants with higher yields. Cecil Salmon, a biologist and wheat expert on General Douglas MacArthur's team in Japan after 1945, collected 16 varieties of wheat including Norin 10. He se ...

Wheat
Wheat is a grass widely cultivated for its seed, a cereal grain that is a worldwide staple food. The many species of wheat together make up the genus ''Triticum'' ; the most widely grown is common wheat (''T. aestivum''). The archaeological record suggests that wheat was first cultivated in the regions of the Fertile Crescent around 9600 BCE. Botanically, the wheat kernel is a type of fruit called a caryopsis. Wheat is grown on more land area than any other food crop (, 2014). World trade in wheat is greater than for all other crops combined. In 2020, world production of wheat was , making it the second most-produced cereal after maize. Since 1960, world production of wheat and other grain crops has tripled and is expected to grow further through the middle of the 21st century. Global demand for wheat is increasing due to the unique viscoelastic and adhesive properties of gluten proteins, which facilitate the production of processed foods, whose consumption is inc ...

Monkombu Sambasivan Swaminathan
Mankombu Sambasivan Swaminathan (born 7 August 1925) is an Indian agronomist, agricultural scientist, plant geneticist, administrator and humanitarian. Swaminathan is a global leader of the green revolution. He has been called the main architect of the green revolution in India for his leadership and role in introducing and further developing high-yielding varieties of wheat and rice. Swaminathan's collaborative scientific efforts with Norman Borlaug, spearheading a mass movement with farmers and other scientists and backed by public policies, saved India and Pakistan from certain famine-like conditions in the 1960s. His leadership as Director General of the International Rice Research Institute (IRRI) in the Philippines was instrumental in his being awarded the first World Food Prize in 1987, recognized as the Nobel or the highest honours in the field of agriculture. United Nations Environment Programme has called him 'the Father of Economic Ecology'. Swaminathan contribute ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Biodiversity
Biodiversity or biological diversity is the variety and variability of life on Earth. Biodiversity is a measure of variation at the genetic (''genetic variability''), species (''species diversity''), and ecosystem (''ecosystem diversity'') level. Biodiversity is not distributed evenly on Earth; it is usually greater in the tropics as a result of the warm climate and high primary productivity in the region near the equator. Tropical forest ecosystems cover less than 10% of earth's surface and contain about 90% of the world's species. Marine biodiversity is usually higher along coasts in the Western Pacific, where sea surface temperature is highest, and in the mid-latitudinal band in all oceans. There are latitudinal gradients in species diversity. Biodiversity generally tends to cluster in hotspots, and has been increasing through time, but will be likely to slow in the future as a primary result of deforestation. It encompasses the evolutionary, ecological, and cultural ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Developing Nations
A developing country is a sovereign state with a lesser developed industrial base and a lower Human Development Index (HDI) relative to other countries. However, this definition is not universally agreed upon. There is also no clear agreement on which countries fit this category. The term low and middle-income country (LMIC) is often used interchangeably but refers only to the economy of the countries. The World Bank classifies the world's economies into four groups, based on gross national income per capita: high, upper-middle, lower-middle, and low income countries. Least developed countries, landlocked developing countries and small island developing states are all sub-groupings of developing countries. Countries on the other end of the spectrum are usually referred to as high-income countries or developed countries. There are controversies over this term's use, which some feel it perpetuates an outdated concept of "us" and "them". In 2015, the World Bank declared that ...

Green Revolution
The Green Revolution, also known as the Third Agricultural Revolution, was a period of technology transfer initiatives that saw greatly increased crop yields and agricultural production. These changes in agriculture began in developed countries after World War II and spread globally till the late 1980s. In the late 1960s, farmers began incorporating new technologies such as high-yielding varieties of cereals, particularly dwarf wheat and rice, and the widespread use of chemical fertilizers, pesticides, and controlled irrigation. Agriculture also saw the adoption of newer methods of cultivation, including mechanization. These changes were often implemented as a package of practices meant to replace traditional agricultural technology. Both the Ford Foundation and the Rockefeller Foundation were heavily involved in its initial development in Mexico. One key leader was agricultural scientist Norman Borlaug, the "Father of the Green Revolution", who received the Nobel Peace Prize ...

Journal Of Heredity
The ''Journal of Heredity'' is a peer-reviewed scientific journal concerned with heredity in a biological sense, covering all aspects of genetics. It is published by Oxford University Press on behalf of the American Genetic Association. History The trends in topics that have been published in the journal reflect the history of the discipline of genetics.Crow, J F (2004). "Genetics: Alive and Well. The First Hundred Years as Viewed Through the Pages of the Journal of Heredity. WILHEMINE E. KEY 2003 INVITATIONAL LECTURE". J Hered (95(5):365–374. Early issues included many papers on eugenics, particularly under the editorial leadership of the journal's first two editors-in-chief, Paul Popenoe and R. C. Cook. Emphasis on eugenics in the journal declined throughout the 1940s and 1950s as support for the topic waned in the scientific community and the general public; when Cook's daughter, Barbara Kuhn, took over as editor in 1962 after her father's 40-year service, "...the subject ...

Stem Rust
Stem rust, also known as cereal rust, black rust, red rust or red dust, is caused by the fungus ''Puccinia graminis'', which causes significant disease in cereal crops. Crop species that are affected by the disease include bread wheat, durum wheat, barley and triticale. These diseases have affected cereal farming throughout history. The annual recurrence of stem rust of wheat in North Indian plains was discovered by Prof. K.C. Mehta. Since the 1950s, wheat strains bred to be resistant to stem rust have become available. Fungicides effective against stem rust are available as well. In 1999 a new virulent race of stem rust was identified against which most current wheat strains show no resistance. The race was named TTKSK (e.g. isolate Ug99). An epidemic of stem rust on wheat caused by race TTKSK spread across Africa, Asia and the Middle East, causing major concern due to the large numbers of people dependent on wheat for sustenance, thus threatening global food security.

Norman Borlaug
Norman Ernest Borlaug (; March 25, 1914September 12, 2009) was an American agronomist who led initiatives worldwide that contributed to the extensive increases in agricultural production termed the Green Revolution. Borlaug was awarded multiple honors for his work, including the Nobel Peace Prize, the Presidential Medal of Freedom and the Congressional Gold Medal. Borlaug received his B.S. in forestry in 1937 and Ph.D. in plant pathology and genetics from the University of Minnesota in 1942. He took up an agricultural research position with CIMMYT in Mexico, where he developed semi-dwarf, high- yield, disease-resistant wheat varieties. During the mid-20th century, Borlaug led the introduction of these high-yielding varieties combined with modern agricultural production techniques to Mexico, Pakistan, and India. As a result, Mexico became a net exporter of wheat by 1963. Between 1965 and 1970, wheat yields nearly doubled in Pakistan and India, greatly improving the food securi ...
