Morphological markers are the traditionally proven and accepted tools as a first step, among a host of other techniques, for characterization of plant germplasm. The technique remains useful as a highly recommended first step to be undertaken prior to more in depth biochemical or molecular studies in okra germplasm. Ten parental accessions and 51 Fl progenies of A. esculentus and A. caillei evaluated for 15 qualitative and eight quantitative traits exhibited significant variations in all quantitative traits studied. Clustering pattern based on quantitative traits largely revealed no duplicates and clustering pattern especially among parental accessions, appears to reflect relationship based upon speciation as parental accessions belonging to A. caillei are clustered towards one end of the dendrogram, while members belonging to A. esculentus clustered towards the opposite end. Contributions of three principal components were 45.98 %, 23.31 %, and 14.46% for the first (PC1), second (PC2) and third (PC3) respectively, with corresponding Eigen values of 3.21837, 1.63171 and 1.01212 respectively, cumulating into maximum of 83.75 % of total variance. These results demonstrate possibility of producing superior hybrids of okra through artificial cross-pollination.
