Summary
The F1 hybrid (S. indicum ×S. melongena) resembled the wild parent and exhibited hybrid vigour. In spite of normal meiosis, it was partly sterile with 48.9% stainable pollen. Its sterility is attributed to cryptic structural hybridity.
The amphidiploid (S. indicum — melongena) obtained through colchicine treatment was fully fertile. It showed a low multivalent formation during meiosis and it is classified as a segmental allopolyploid. p ]The practical value of the hybrid in eggplant breeding has been indicated.
