What did Dr Norman Borlaug do?
Known as the “Father of the Green Revolution,” Borlaug helped lay the groundwork for agricultural technological advances that alleviated world hunger. Borlaug studied plant biology and forestry at the University of Minnesota and earned a Ph. in plant pathology there in 1942.
Which country developed the semi dwarf variety of wheat?
Mexico
It was developed in Mexico in the mid-1940s-50s by Dr. Norman Borlaug, geneticist, plant pathologist and Nobel Peace Prize winner, as a way to increase wheat yields and make the country more self-sufficient in food production.
Which is the disease resistant variety of wheat?
The best known APR genes in wheat are Sr2, a stem rust resistance gene and Lr34, a gene that provides resistance to leaf and stripe rust and powdery mildew. These genes have been used in commercial wheat varieties for almost 100 years.
Which metal is rust proof?
To prevent oxidation and breakdown of metal products, such as handrails, tanks, appliances, roofing or siding, you can choose metals that are “rust-proof” or more accurately, “corrosion-proof.” Four basic types of metals fall into this category: Stainless steel. Aluminum metal. Copper, bronze or brass.

Who saved the most lives in history?
Norman Borlaug
Norman Borlaug, the man who saved more human lives than anyone else in history, has died at age 95. Borlaug was the Father of the Green Revolution, the dramatic improvement in agricultural productivity that swept the globe in the 1960s. For spearheading this achievement, he was awarded the Nobel Peace Prize in 1970.
What was the first major problem Norman Borlaug tried to fix for the Mexican wheat farmers?
Dr. Borlaug’s initial goal was to create varieties of wheat adapted to Mexico’s climate that could resist the greatest disease of wheat, a fungus called rust. He accomplished that within a few years by crossing Mexican wheats with rust-resistant varieties from elsewhere.

What did Stakman discover about rust in wheat?
Stakman, in his speech entitled “These Shifty Little Enemies that Destroy our Food Crops”, discussed the manifestation of the plant disease rust, a parasitic fungus that feeds on phytonutrients in wheat, oats, and barley crops. He had discovered that special plant breeding methods produced plants resistant to rust.
Where did Borlaug’s dwarf spring wheat come from?
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.
Why is wheat important to World Food Security?
Essentially, wheat provides roughly 20 percent of the calorie intake of the world, making crop protection very essential for world food security, with cereal rust affecting barley, rye, oats, and triticale crops, as well. The lead researcher says that international research had targeted stem rust.
