How seed production occurs in brinjal?

Fully Ripe fruits are harvested for seed extraction. The outer covering is peeled off and the flesh with the seed is cut into thin slices. These are then softened by soaking till the seed is separated from the pulp to which water is added gradually. Keep the material to stand overnight which make the separation of seed from the pulp easier. After separation, dip the seed into the water and reject those seeds which float on the water. Seeds should be dried in partial shade before storing. The isolation distance is 50-100 m.  The seed yield is 100-120kg/ha.
