METHOD FOR IDENTIFYING PLANT MATERIAL THAT SHOWS A REDUCED DISCOLOURATION, PLANTS THUS IDENTIFIED AND USE OF THE IDENTIFIED PLANTS FOR THE PRODUCTION OF COMMERCIAL CROP PLANTS SHOWING A REDUCED DISCOLOURATION

摘要

The invention relates to a method for testing a plant or plant part for e xhibiting a reduced or absent wound-induced surface discolouration as compar ed to a control plant or plant part, which method comprises providing a plan t or plant part that is obtained from a plant population that shows genetic variation, in particular a gene bank; optionally creating a wound surface on the plant or plant part; incubating the plant or plant part or the wound su rfaces created thereon to allow for discolouration to occur therein or there on; observing the discolouration in or on the plants or plant parts; compari ng the observed discolouration with the discolouration that is observed in t he control plant or plant part to assess whether the plant or plant part sho ws no discolouration or a discolouration that is reduced as compared to the control plant or plant part; and identifying a plant or plant part that show s no discolouration or a discolouration that is reduced as compared to the c ontrol plant or plant part as a plant that harbours the reduced wound-induce d surface discolouration trait.
