Abstract:
The FI hybrids, (A.esculentus x A. tetraphyllus resembled the wild parent and
exhibited hybrid vigour. Its meiosis was abnormal snowing more of univalents and less of
bivalents and was completely sterile. The amphidiploid (A. csculentus-tctraphyllus) obtained
through colchicine treatment was fully fertile. It showed a low multivalent formation during
meiosis and can survive as a new synthetic species. The practical value of the amphidiploid
in okra breeding has been indicated.
