ABSTRACT

The sesame genotypes which were endowed with high fitness exhibited low adaptedness and vice-versa. This paradoxical relationship is eponymously called as ayala's paradox. The progenies of the cross combination namely, TMV 5 x TNAU 120 which showed high fitness may be intermated with the progenies of the cross combination such as TNAU 120 x TMV 3 which high adaptedness, to evolve elite lines with higher fitness coupled with higher adaptedness which will eventually result in higher seed yield in farmer's field.
