Soybean plants with dominant selectable trait for herbicide resistance

摘要

The utilization of a positive selection seed screening process to isolate rate variants with resistance to a herbicide is described. The ability to screen large numbers of mutagenized seed has made it feasible to pursue and isolate plants with low frequency dominant herbicide-resistance mutations. The dominant herbicide resistance mutations are useful for many applications including expanding the utility of sulfonylurea herbicides for soybean weed control, production of F1 and F2 seeds, and as selectable markers for efficient seed purification.
