Genetic variability and correlation analysis in okra [Abelmoschus esculentus (L.) Moench.]

Genetic variability, heritability and genetic advance of 15 quantitative characters in 19 diverse okra genotypes were studied. Significant differences among genotypes were observed for all the characters under study. Estimates of phenotypic coefficient of variation and genotypic coefficient of variation were found to be high for internodal length, number of branches/plant, number of fruits/plant, number of seeds/pod and fruit yield/plant. The characters number of seeds/pod, internodal length, number of branches/plant, fruit yield/plant, number of fruits/plant, plant height and 100-seed weight exhibited high heritability along with high genetic advance which indicated that there was more number of additive factors and, therefore, further improvement could be brought about by selection. The fruit yield/plant was positively and significantly correlated with fruit length, fruit diameter, fruit weight and number of fruits/plant.
