Genetically Engineered Corn (GE Corn) is corn that has had its DNA modified through the process of genetic engineering. Varieties of GE corn that contain more than one trait are referred to as "stacked." Most GE corn falls into one of two categories:
Other varieties include:
- Plant Genetic Systems: Male Sterile (Terminator) Corn (Event MS3), deregulated in the U.S. in February 1996 but never sold commercially
- Pioneer Hi-Bred: Male Sterile (Terminator) Glufosinate Tolerant Corn (676, 678, 680), deregulated in the U.S. in May 1998 but never sold commercially
- AgrEvo (Bayer CropScience): Male Sterile (Terminator) Glufosinate Tolerant Corn (MS6), deregulated in the U.S. in March 1999 but never sold commercially
- Monsanto: High Lysine Corn (LY038), deregulated in the U.S. in February 2006
- Syngenta: Thermostable Alpha-Amylase Corn (3272), deregulated in the U.S. in February 2011
- Monsanto: Drought Tolerant Corn (MON 87460), deregulated in the U.S. in May 2011
- Pioneer Hi-Bred: Male Sterile/Female Inbred Corn (DP-32138-1), deregulated in the U.S. in June 2011

- 2000: 25%
- 2001: 26%
- 2002: 34%
- 2003: 40%
