Abstract

This invention relates to a method for the production of stable, genetically transformed cereal plants, other than maize or rice, that comprise an exogenous DNA expressing phosphinothricin acetyl transferase to impart resistance to phosphinothricin in said cereal plants. Cereal plants within the scope of the method include, but are not limited to, wheat, barley and oats. The invention also pertains to a method of breeding said transgenic cereal plants with a either a non-transgenic plant or a transgenic plant, and the obtention of fertile transgenic plants and seed therefrom.
