Norman Ernest Borlaug (/ ˈ b ɔːr l ɔː ɡ /; March 25, 1914 – September 12, 2009) [2] was an American agronomist who led initiatives worldwide that contributed to the extensive increases in agricultural production termed the Green Revolution.
A Japanese dwarf wheat cultivar Norin 10 developed by Japanese agronomist Gonjiro Inazuka, which was sent to Orville Vogel at Washington State University by Cecil Salmon, was instrumental in developing Green Revolution wheat cultivars. In the 1960s, with a food crisis in Asia, the spread of high-yielding variety rice greatly increased.
It played a significant part in the Green Revolution. IR8 was the eighth of 38 crossbred rice varieties in a 1962 experiment by IRRI. [1] It was a cross of Peta, a high yield rice variety from Indonesia, and Dee-geo-woo-gen (DGWG), a dwarf variety from Taiwan.
The Green Revolution has been a team effort and much of the credit for its spectacular development must go to the Indian officials, organizations, scientists, and farmers. However, to you, Dr. Swaminathan, a great deal of the credit must go for first recognizing the potential value of the Mexican dwarfs.
The first Green Revolution rice variety, IR8, was produced in 1966 at the International Rice Research Institute through a cross between an Indonesian variety named "Peta" and a Chinese variety named "Dee Geo Woo Gen". [94] Green Revolution varieties were bred to have short strong stems so that the rice would not lodge or fall over.
Rice eui mutants amass bioactive Gibberellins at high levels, which suggests cytochrome P450 mono-oxygenase is a main enzyme responsible for deactivation GA in rice. [29] The Gamt1 and gamt2 genes encode enzymes that methylate the C-6 carboxyl group of GAs. [30] In a gamt1 and gamt2 mutant, concentrations of GA in developing seeds is increased ...
The most popular HYVs can be found among wheat, corn, soybean, rice, potato, and cotton. They are heavily used in commercial and plantation farms. The Green Revolution in the late 1960s (or generally, in the second half of the 20th century) [1] introduced farmers to cultivation of food crops using HYV seeds, although their ancestral roots may ...
Surajit Kumar De Datta is an Indian agronomist who is best known for his high yield variety of rice IR-8 that contributed significantly to the Green Revolution across Asia. [1] Over the course of 27 years, he worked at the International Rice Research Institute in Philippines helping Southeast Asia get self-sufficiency in rice production. [2]
