ABSTRACT:
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 F.sub.1 and F.sub.2 seeds, and as selectable markers for efficient seed purification.
