THE INTERSPECIFIC HYBRIDIZATION, A SOURCE OF VARIABILITY : AN EXAMPLE THE EGGPLANT
Usually, after the interspecific-cross, the breeder comes back rapidly to the wished variety alternating self-fertilization, selection and back-crossing phases.
In a crossing programme destined to transfer the resistance to Pseudomonas solanacearum from Solanum aethiopicum to Solanum melongena, inter-crossing phases were put in place of self-fertilization phases. With this method it was possible to obtain not only a very good resistance to Pseudomonas solanacearum but also a large variation in the shape and colour of the fruits.
With this method it would be possible to widen the variability for some species.
