The present invention relates to a tomato plant (Solanum lycopersicum L.) comprising a genetic determinant that leads to the absence or reduction of green staining from the green vegetative parts of the plant upon contact, as compared to a plant not carrying the said genetic trait, which genetic determinant is obtainable from a tomato plant comprising said genetic determinant, representative seed of which was deposited with the NCIMB under deposit number NCIMB 41845. The said genetic determinant is preferably located on Linkage Group 9 between positions 1750800 bp and 4517648 bp, preferably between positions 1939546 bp and 2970346 bp, most preferably at about position 2454946 bp on a physical map.
