Interspecific hybridization in okra is of immense value to exploit the diversity of species in the
genus Abelmsochus for developing male sterile lines and/or advance breeding lines possessing
resistance to YVMV and ELCV diseases. The present investigation was carried out during the
year 2015-16 to study the pattern of interspecific hybridization in genus Ablemoschus involving
ten wild species viz., A. angulosus var. angulosus, A. angulosus var. grandiflorus, A. caillei, A.
ficulneus, A. manihot ssp. tetraphyllus, A. moschatus, A. tetraphyllus var. pungense, A.
tetraphyllus var. tetraphyllus, A. tuberculatus and new taxa IC 0433556 with eight genotypes of
cultivated species (Abelmoschus esculentus). Hand pollination was undertaken; fruit set, seed
set, seed germination and pollen viability per cent were calculated. From the present
investigation, it was found that the cultivated A. esculentus genotypes were compatible as male
parents with A. caillei, A. manihot ssp. tetraphyllus and A. tetraphyllus var. tetraphyllus, A.
tuberculatus. Interestingly, there was no compatibility when A. tetraphyllus var. pungense and
new taxa IC 0433556 crossed with cultivated okra genotypes (IIHR-285 and 10-11-594).
However, there was limited fruit set observed in A. angulosus var. angulosus, A. angulosus var.
grandiflorus, A. moschatus and A. ficulneus. The F1 seeds thus obtained were failed to
germinate due to non-viable seeds. The significant difference (p
