Rice is described that is tolerant/resistant to herbicides, for example, ACCase inhibitors, and HPPD inhibitors, or both. For ACCase inhibitors, 2 different chromosome regions act synergistically in providing resistance/tolerance to the same herbicide class. Use of the herbicide resistant/tolerant rice for weed control and methods of producing tolerant/resistant rice are also disclosed.

Methods and compositions for combinations of mutations associated with herbicide resistance/tolerance in rice

Rice is described that is tolerant/resistant to a plurality of herbicides, for example, ACCase and HPPD inhibitors. Use of the rice for weed control and methods of producing tolerant/resistant rice are also described.

Rice resistant to HPPD and ACCase inhibiting herbicides

Mutant rice resistant/tolerant to ACCase inhibiting herbicides, in particular FOP herbicides, are listed in Table 1. The ACCase inhibiting herbicides used for selection include quizalofop. An exemplary mutant rice tolerant to an ACCase herbicide is disclosed, with a rice genome having G2096S or the equivalent, in the carboxyl transferase domain of the ACCase coding gene, using the Black-Grass numbering system. This mutation shows differential response to FOPs vs. DIMs herbicides, and a greater differential with comparable non-resistant rice lines. Methods to control weeds and methods to produce herbicide resistant rice including transgenic rice, are disclosed.
