Abstract:
1. A herbicide-resistant hybrid rice plant produced by the process of: (a) crossing or back-crossing a first rice plant with other rice germplasm; (b) growing rice plants resulting from said crossing or back-crossing in the presence of at least one herbicidally-effective imidazolinone at levels of the imidazolinone herbicide that would normally inhibit the growth of a rice plant; and (c) selecting for further propagation hybrid rice plants resulting from said crossing or back-crossing, wherein the hybrid rice plants selected are plants that grow without significant injury in the presence of the imidazolinone herbicide; wherein: (d) the first rice plant is selected from the group consisting of the rice plants having ATCC accession numbers PTA-905, PTA-902, PTA-903, PTA-906, PTA-907, PTA-908, 203419, 203420, 203421, 203422, 203423, 203424, 203425, 203426, 203427, 203428, 203429, 203430, 203431, 203432, and 203433; and (e) said herbicide-resistant hybrid rice plant exhibits the same phenotype of resistance and sensitivity towards imidazolinone herbicides and sulfonylurea herbicides as the phenotype exhibited by the first rice plant, as exemplified by Tables 2, 3, and 4 of the Specification.
