These were correlated to assess the level of associations existing between these elements. Concentrations of these elements were juxtaposed with their recommended daily dietary intake (RDI) in the individual accessions of okra and their variability with other traits examined for future improvement works towards breeding for high or low micro nutrient containing variety (ies).
Mucilage content of Twenty one (21) accessions of okra (Abelmoschus spp L.), May 20, 2014

Fresh fruits of the accessions were harvested and mucilage extracted using improvised cold maceration method. The means of maximum viscosity ranged from 53.0 to 366.8 bu (Brabender unit) for all accessions studied. Mucilage yield from the various accessions of okra were significantly variable. The accessions DKA, Amanfrom, Asontem NV, Yeji-Local and Kortebortor-BAR yielded significant amounts of mucilage. Accessions belonging to the West African Taxon (Abelmoschus caillei L.) recorded the highest significant mucilage yield. Rheological properties of mucilage solution were explicitly pseudoplastic and parallel to that of guar gum. This research also confirmed that higher concentration of mucilage solution culminates in increased viscosity, but increasing the pH and temperature decreases viscosity. Mucilage was generally soluble in water but insoluble in ethanol.
