Rice is described that is tolerant/resistant to AHAS/ALS inhibitors because of a plurality of mutations that act synergistically in providing resistance/tolerance to the herbicide. Tolerance/resistance is due to presence of combined mutations in the rice leading to amino acid substitutions (A205V and G654E) in the AHAS/ALS enzyme. Use of the rice for weed control and methods of producing tolerant/resistant rice are also disclosed.

Effects of a plurality of mutations to improve herbicide resistance/tolerance in rice

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.
