Why did Norman Borlaug use shuttle breeding?
In an effort to speed up the programme Norman Borlaug came up with the idea of “shuttle breeding”. By growing his breeding plants in central Mexico during the summer and then in Northern Mexico during the winter he was able to double the rate of the wheat breeding programme.
What did Norman Borlaug do with cross breeding?
Borlaug crossbred the semi-dwarf Norin 10/Brevor 14 cultivar with his disease-resistant cultivars to produce wheat varieties that were adapted to tropical and sub-tropical climates.
What was the excellent unintended consequence of shuttle breeding?
This approach became known as “shuttle breeding.” He recognized that an unintended benefit of the shuttle breeding was that the resulting varieties resisted many different varieties of pests and diseases and they didn’t care how long the days were during their growing season.
What was shuttle breeding?
They created a revolutionary high volume “shuttle breeding” program. They bred wheat using two distinct latitudes and seasons in the same year. In summer they bred wheat at high altitude near Mexico City, in winter they used the Yaqui Valley of northern Mexico—an irrigated part of the Sonoran Desert.
What did shuttle breeding add to the wheat cross breeding program?
Borlaug began growing two crops of wheat a year in contrasting growing conditions. As a result, Borlaug’s “shuttle breeding” produced highly adaptive wheat, yielding twice the production potential.
What is shuttle breeding?
Shuttle breeding uses diverse ecological environments to develop improved varieties with higher adaptability. Alternate generations of early breeding materials are grown under different environments. The basis of shuttle breeding is cooperative research among nations and institutions.
Why is Borlaug infamous to environmentalists?
Not only did Borlaug’s ‘high-yielding’ seeds demand expensive fertilisers, they also needed more water. Both were in short supply, and the revolution in plant breeding was said to have led to rural impoverishment, increased debt, social inequality and the displacement of vast numbers of peasant farmers,” he wrote.
Who developed shuttle breeding?
Norman Borlaug invented shuttle breeding. It entailed using two different geographic locations to breed two generations of plants yearly. He did “summer” wheat breeding at the International Center for Maize and Wheat Improvement (CIMMYT) near Mexico City.
Who developed Norin 10?
scientist Gonjoro Inazuka
EL BATAN, Mexico (CIMMYT) — In 1935, Japanese scientist Gonjoro Inazuka crossed a semi-dwarf Japanese wheat landrace with two American varieties resulting in an improved variety, known as Norin 10.
What is Dee Gee Woo Gen?
Dee-geo-woo-gen is a spontaneous dwarf mutant of rice which is characterized by dwarf plant habit (60 cm; half than the traditional tall varieties), stiff and erect leaves to ensure maximum exposure to sunlight, photo insensitivity and lack of seed dormancy.
Who is known as Indian father of Green Revolution?
Mr. Swaminathan
With his recent statements, Mr. Swaminathan, who is regarded in India as the father of the Green Revolution, added a prominent voice to a growing chorus of experts warning that the effect on global grain production from rising temperatures would be far more severe than previously believed.
What is Norin?
Norin is a traditional meal eaten across Uzbekistan consisting of layers of finely chopped meat and freshly cooked noodles with various Uzbek spices.
Which is dwarfing gene in wheat?
Dwarfing genes (Rht) are known for yield gains due to lodging resistance and partitioning of assimilates into ear. The available and commercially exploited sources of dwarfism in Indian spring wheat are Rht1 and Rht2 genes inspite of availability of over 20 dwarfing genes.
What is shuttle breeding at Borlaug?
Borlaug began growing two crops of wheat a year in contrasting growing conditions. As a result, Borlaug’s “shuttle breeding” produced highly adaptive wheat, yielding twice the production potential.
What is the Borlaug Fellowship?
The Borlaug Fellowship Program honors Norman E. Borlaug, the American agronomist, humanitarian and Nobel laureate known as the “Father of the Green Revolution.”
What is shuttle breeding in agriculture?
Shuttle Breeding. Borlaug began growing two crops of wheat a year in contrasting growing conditions. As a result, Borlaug’s “shuttle breeding” produced highly adaptive wheat, yielding twice the production potential.
What is the NAPB Borlaug scholars travel grant program?
Thank you for your interest in supporting the NAPB Borlaug Scholars travel grant and scholarship program. This program enhances the recruitment, development, and professional opportunities for our future plant breeders by covering expenses for recipients to attend the NAPB Annual Meeting.
