The Establishment of Genetically Engineered Canola Populations in the U.S.

Figure 1

Distribution and density of feral canola populations in North Dakota road surveys (2010).

Circles indicate locations of sampling sites; diameter of circle indicates plant density; gray circles indicate no canola present. The presence of genetically engineered protein in the vouchered specimen is shown by color: red – glyphosate resistance; blue – glufosinate resistance; yellow – dual resistance traits; green – non-transgenic. Canola fields are indicated by stippling based on 2009 USDA National Agricultural Statistics Service report ( Stars show the locations of oilseed processing plants (3). Solid lines illustrate interstate, state and county highways.
