Abstract

This invention relates to a plant, seed, variety, inbred and hybrid. More specifically, the invention relates to plant having resistance to at least two herbicides. The invention also relates to methods of producing a hybrid plant and methods of producing a plant having resistance to at least two herbicides.

Claims

1. A soybean seed having genes for resistance to glyphosate and sulfonylurea herbicides, wherein said glyphosate gene is an EPSPS gene which confers tolerance to glyphosate, and said sulfonylurea gene is an ALS gene which confers tolerance to sulfonylurea.

2. A soybean plant produced by growing the seed of claim 1.

3. Pollen of the plant of claim 2.

4. Ovule or ovules of the plant of claim 2.

5. Tissue culture of the plant of claim 2.

6. A plant regenerated from the tissue culture of claim 5 wherein said plant comprises said EPSPS gene and said ALS gene.

7. A method to produce a hybrid seed comprising crossing a first parent plant with a second parent plant and harvesting the resultant F₁ hybrid seed, wherein said first or second parent plant is the plant of claim 2.

8. A first generation (F₁) hybrid plant produced by growing said hybrid seed of claim 7 wherein said first generation hybrid plant comprises said EPSPS gene and said ALS gene.

9. Progeny of the plant of claim 8 wherein said progeny plant comprises said EPSPS gene and said ALS gene.

10. The soybean seed of claim 1, wherein said glyphosate gene is CP4.

11. The soybean seed of claim 1, wherein said ALS gene is derived from W20.

12. The soybean seed of claim 1, wherein said seed is capable of producing a commercially acceptable soybean plant.
