List of varieties of genetically modified maize

This article provides a comprehensive list of genetically modified maize varieties. Genetically modified maize, also known as genetically engineered maize or GM maize, refers to maize plants that have been modified through genetic engineering techniques to exhibit specific traits or characteristics.

Bt Maize

Bt maize is a type of genetically modified maize that has been engineered to produce a toxin derived from the bacterium Bacillus thuringiensis (Bt). This toxin is toxic to certain pests, such as the European corn borer and the corn rootworm, providing protection against these insects without the need for excessive pesticide use. Some popular Bt maize varieties include:

• MON 810: Developed by Monsanto, MON 810 is one of the most widely grown Bt maize varieties. It provides protection against the European corn borer.

• Bt11: Developed by Syngenta, Bt11 is another popular Bt maize variety that offers resistance against the European corn borer and certain other pests.

Herbicide-Tolerant Maize

Herbicide-tolerant maize varieties have been genetically modified to tolerate specific herbicides, allowing farmers to effectively control weeds without harming the maize plants. Some notable herbicide-tolerant maize varieties include:

• Roundup Ready Maize: Developed by Monsanto, Roundup Ready Maize is engineered to tolerate the herbicide glyphosate, commonly known as Roundup. This allows farmers to spray glyphosate-based herbicides to control weeds without damaging the maize crop.

• Liberty Link Maize: Developed by Bayer CropScience, Liberty Link Maize is genetically modified to tolerate the herbicide glufosinate. It provides effective weed control while maintaining the health of the maize plants.

Stacked Traits Maize

Stacked traits maize refers to genetically modified maize varieties that possess multiple genetically engineered traits. These traits can include both insect resistance and herbicide tolerance, providing farmers with comprehensive pest and weed control options. Some prominent stacked traits maize varieties include:

• SmartStax: Developed through a collaboration between Monsanto and Dow AgroSciences, SmartStax is a stacked traits maize variety that combines multiple Bt traits for insect resistance and herbicide tolerance. It offers protection against a wide range of pests and allows for effective weed management.

• PowerCore: Developed by Dow AgroSciences, PowerCore is another stacked traits maize variety that provides multiple modes of action against pests and weeds. It combines Bt traits for insect resistance with herbicide tolerance traits.

Other Genetically Modified Maize Varieties

Apart from the aforementioned categories, there are several other genetically modified maize varieties that possess unique traits or characteristics. These include:

• Golden Rice: Golden Rice is a genetically modified maize variety that has been engineered to produce beta-carotene, a precursor of vitamin A. It aims to address vitamin A deficiency in developing countries.

• Drought-Tolerant Maize: Drought-tolerant maize varieties have been genetically modified to withstand periods of water scarcity. These varieties help farmers mitigate the impact of drought on maize yields.
