Abstract

Abelmoschus esculentus (L.) Moench. (okra) and Abelmoschus caillei (A.Chev.) Stevels (West African okra) are commonly grown as vegetable crops in southern Nigeria. This study examined the intra- and interspecific relationships between the two species, using seven accessions of A. esculentus and eight of A. caillei. Twelve quantitative and 12 qualitative characters were pooled for the analyses. Leaf characters were measured at the inception of the third leaf, floral characters at inception of flowering. Growth pattern was indeterminate for A. esculentus and determinate for A. caillei; stem was weak and procumbent for A. esculentus, stiff and erect for A. caillei; internode length was short/moderate in A. esculentus, long in A. caillei. Epicalyses terminated at the onset of the fruit in A. esculentus, but were hard and persistent in A. caillei; fruit shape was fusiform in A. esculentus, ovoid/oblong in A. caillei, erect in A. esculentus, pendulous in A. caillei. Flowering period was longer in A. caillei (>43 days) than in A. esculentus (maximum of 43 days). A. caillei produced more fruits (77%) than A. esculentus (44%); taller plants were recorded for A. caillei (34.50–52.20 cm) than for A. esculentus (21.30–30.10 cm). Greater intraspecific variation was observed in A. esculentus (five clusters) than in A. caillei (three clusters). The species showed closer interspecific relationship at higher Euclidean distance.
