Twenty-nine okra accessions from different agro-ecological regions in Nigeria were grown during the rainy and dry seasons, between 2006 and 2007 at Abeokuta (derived savanah) and Ilishan (rainforest) and assessed to determine their genetic variability, heritability and genetic advance from eight yield related characters. The experiment was laid out in a Randomized Complete Block Design with five replications. There was high genotypic coefficient of variability, % broad-sense heritability and genetic advance in traits such as plant height (26.2, 90.7, 51.5), fresh pod length (23.9, 98.5, 48.8), fresh pod width (23.9, 98.5, 48.8), mature pod length (28.6, 98.5, 52.3), branching per plant (29.3, 82.3, 54.8) and pod weight per plant (33.9, 90.0, 63.3), suggesting the effect of additive genes and reliability of selection based on phenotype of these traits for crop improvement. The positive and significant phenotypic and genotypic correlation between plant height at maturity, fresh pod width, seeds per pod and pods per plant, branches per plant with seed weight per plant and pod weight per plant, suggests that selection on the basis of the phenotype of these characters will lead to high seed and pod yield in okra. ; Se cultivaron 29 accesiones de quingombó de diferentes regiones agro-ecológicas en Nigeria durante las estaciones lluviosas y secas de 2006 y 2007 en Abeokuta (derivada de la sabana) y Ilishan (selva) y se evaluaron para determinar la variabilidad genética, heredabilidad y avance genético de ocho caracteres relacionados con el rendimiento. El experimento fue en bloques completos al azar con cinco repeticiones. Hubo un alto coeficiente de variabilidad genotípica, % de heredabilidad en sentido amplio y avance genético en caracteres como altura de planta (26,2; 90,7; 51,5, respectivamente), longitud de vaina fresca (23,9; 98,5; 48,8), ancho de vaina fresca (23,9; 98,5; 48,8), longitud de vaina madura (28,6; 98,5; 52,3), ramas por planta (29,3; 82,3; 54,8) y peso de vaina por planta (33,9; 90,0; 63,3), lo que ...
