Abstract
The agene of the “corky root” disease of Dutch glasshouse tomatoes is a non-sporulating fungus of the group Mycelia sterilia. The breeding programme for “corky root” resistance is based on the resistance derived from Lycopersicum glandulosum. To test the best way of backcrossing we made backcrosses in all possible combinations between tomato, triploid F 1 hybrid (tomato × Lycopersicum glandulosum) and Lycopersicum glandulosum. Our experiments showed that the shortest way from the wild resistant Lycopersicum back to the commercial type of the tomato possessing the desired resistance was backcrossing the F 1 triploid hybrid to Lycopersicum glandulosum.
