Twelve plants were studied per population and per herbicide. Phenotype classes: A, plants whose clones were rated sensitive or moderately resistant in the presence and in the absence of safener, B, plants whose clones showed a moderate decrease in sensitivity in the presence of the safener (from S to M or from M to R); C, plants whose clones showed a substantial decrease in sensitivity in the presence of the safener (from S to R); D, plants whose clones were rated M or R in the presence and in the absence of safener.
