The invention relates to a method for screening a population of plants or plant parts for the presence therein of individuals that show a reduced wound-induced surface discolouration as compared to a control plant or plant part, which method comprises providing a population of plants or parts of the plants from the population； creating a wound surface on the plants or plant parts to be screened and on the control plants or plant parts； incubating the wound surfaces to allow for discolouration to occur therein or thereon； observing the wound surface discolouration in or on the plants or plant parts； comparing the observed wound surface discolouration in or on the plants or plant parts to be screened with the discolouration that is observed on or in the control plant or plant part. The invention further relates to the plants thus selected.
