    Comparative Seeds Germinability and Proximate Chemical Composition of Interspecific F1 Hybrids of Abelmoschus (Esculentus and Caillei) For Edible Pod Yield
    (2016) David, O. J.; Dauda, W. P.; Musa, H.; Musa, N. B.
    Seed viability and hybrid fertility has been a major challenge in the crossability studies between Abelmoschus species including the wild. A preliminary evaluation of interspecific hybrids of West African okra (Abelmoschuscaillei (A. Chev.) Stevels) and the conventional A. esculentus (L.) Moench was undertaken at the University of Ibadan, between September 2014 and May 2015 to determine their comparative performance in terms of seed viability, proximate chemical composition of the parents and the F1 hybrids in order to examine the possibility of utilizing A. caillei in the improvement of A. esculentus. Crosses were carried out, including reciprocals, between the parent materials i.e. two A. esculentus cultivars (UI 4-30 and UI 53-139) on one hand and A. caillei on the other. The F1 hybrids produced the lowest percentage germination of both scarified and scarified seeds. However, that the interspecific hybrids produced seeds with 10 to 80% germination and fertile F1 plants was an indication of the possibility of improving okra seeds (A. esculentus) through interspecific hybridization with A. caillei. The comparison of proximate compositions of the parent materials and the F1 hybrids indicated no significant difference at 5% for the contents of moisture, crude protein, ether extract, crude fibre, nitrogen free extract and ash in every chemical constituent.
