Plant breeding is the science of changing the traits of plants in order to produce desired characteristics. [1] It is used to improve the quality of plant products for use by humans and animals. [2] The goals of plant breeding are to produce crop varieties that boast unique and superior traits for a variety of applications.
The mode of reproduction of a crop determines its genetic composition, which, in turn, is the deciding factor to develop suitable breeding and selection methods. Knowledge of mode of reproduction is also essential for its artificial manipulation to breed improved types.
The Green Revolution, or the Third Agricultural Revolution, was a period of technology transfer initiatives that saw greatly increased crop yields. [ 1 ] [ 2 ] These changes in agriculture began in developed countries in the early 20th century and spread globally until the late 1980s. [ 3 ]
Farmers have manipulated plants and animals through selective breeding for decades of thousands of years in order to create desired traits. In the 20th century, a surge in technology resulted in an increase in agricultural biotechnology through the selection of traits like the increased yield, pest resistance, drought resistance, and herbicide resistance.
Agronomy Journal is a peer-reviewed scientific journal published by American Society of Agronomy. The journal publishes articles related to soil science, crop science, agroclimatology and agronomic modeling, production agriculture, and software.
Crop Science is a bimonthly peer-reviewed scientific journal covering agronomy. It was established in 1961 by founding editor-in-chief H.L. Hamilton and is published by ACSESS (Alliance of Crop, Soil, and Environmental Science Societies) in partnership with Wiley. It is the official journal of the Crop Science Society of America. Since 2013, it ...
Even in average years, however, many agricultural regions, including the U.S. Great Plains, suffer from chronic soil moisture deficits. Cereal crops typically attain only about 25% of their potential yield due to the effects of environmental stress, with dehydration stress the most important cause. Two major trends will likely increase the ...
The Ministry of Agriculture and Cooperatives is major responsible organization for agricultural development in Nepal. This consists of five divisions, two centers, one research and development council, four departments, four projects and autonomous bodies of one research council (Nepal Agriculture Research Council), four corporations and a few development committees and boards.
