Abstract
Novel herbicide resistance has been introduced into rice plants, making the plants resistant to herbicides which normally interfere with a plant's acetohydroxyacid synthase. For the first time it is possible to selectively control the weed called "red rice" in commercial rice fields by planting rice varieties incorporating the novel herbicide resistance, and treating the field with herbicide.
Claims10
A rice plant wherein:
- (a) the growth of said plant is resistant to inhibition by one or more of the following herbicides, at levels of herbicide which would normally inhibit the growth of a rice plant:
- imazethapyr, imazaquin, primisulfuron, nicosulfuron, or a derivative of any of these herbicides;
- and
- (b) said plant is the plant with ATCC accession number 75295;
- or is a mutant, recombinant, or genetically engineered derivative of the plant with ATCC accession number 75295 or of any progeny of the plant with ATCC accession number 75295;
- or is a plant which is the progeny of any of these plants;
- and
- (c) said plant has the herbicide resistance characteristics of the plant with ATCC accession number 75295.
