The interspecific hybridization was carried out in all possible combinations using S. melongena genotypes as female parent and wild species as male parents without reciprocal. Forty flower buds of female parent were taken from each S. melongena cultivar per cross combination. The mature balloon shaped buds with long style of the female parents were emasculated a day before anthesis and covered with butter paper bags. The leftover buds in the clusters and naturally pollinated ones were clipped off. The mature buds in the clusters of male parents were also bagged for collection of uncontaminated pollens. On the day of anthesis on the male parents, the pollen grains were dusted on the stigmatic surface of the emasculated flowers of the female parents. The flowers were re-bagged thereafter and labelled. The degree of crossability was determined as percentage fruit set, number of seeds per fruit, percentage of F1 seed germinated and pollen viability in four wild related Solanum species.
