This oilseed rape (canola, Brassica napa) is genetically modified using Agrobacterium tumefaciens to make it herbicide tolerant against Monsanto's herbicide glyphosate (Roundup). It contains two different transgenes to confer the herbicide tolerance: cp4 epsps as well as goxv247.
It is produced by Monsanto and marketed as "Westar Roundup Ready". GT73 is synonym with RT73, as which it was registerd in the US.
Austria banned GT73 in January 2006
