Abstract

Partitioning of the gene effects for plant height, number of branches per plant, number of fruits per plant, fruit weight and yield per plant was done by deploying P1, P2, F1, F2, B1 and B2 generations of three crosses of okra viz. Arka Anamika x Parbhani Kranti, Arka Anamika x Mohanur Local and Parbhani Kranti x Mohanur Local. Simple Scaling and Joint Scaling tests indicated the presence of non-allelic interactions for yield per plant and its contributing characters in all the three crosses of okra. The result indicated that gene effects were cross specific. Duplicate dominant epistasis played an important role in the inheritance of the characters studied except for fruit weight in the crosses viz., Arka Anamika x Mohanur Local and Parbhani Kranti x Mohanur Local, where complementary recessive epistasis was observed.
