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 ...
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 .
Genetically modified rice are rice strains that have been genetically modified (also called genetic engineering).Rice plants have been modified to increase micronutrients such as vitamin A, accelerate photosynthesis, tolerate herbicides, resist pests, increase grain size, generate nutrients, flavors or produce human proteins.
[4] [5] IRRI is known for its work in developing rice varieties that contributed to the Green Revolution in the 1960s which preempted the famine in Asia. [ 6 ] The institute, established in 1960 aims to reduce poverty and hunger, improve the health of rice farmers and consumers, and ensure environmental sustainability of rice farming.
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 ]
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 ...
Rice can come in many shapes, colours and sizes. This is a list of rice cultivars, also known as rice varieties.There are several species of grain called rice. [1] Asian rice (Oryza sativa) is most widely known and most widely grown, with two major subspecies (indica and japonica) and over 40,000 varieties. [2]
