Genetic variability and correlation studies in Okra (Abelmoschus esculentus (L.) Monech)

The present investigation on genetic variability and correlation in Okra was conducted with thirty-three genotypes including four national check varieties with the objective of improving yield through selection. The results revealed that wide variability was found for different traits in Okra. Invariably, higher values were observed for phenotypic coefficient of variation with respect to corresponding genotypic coefficient of variation indicating the impact of environmental factors towards trait expression. The presence of moderate to high heritability coupled with moderate genetic advance for fruit weight, days to 50% flowering, fruits per plant as well as fruit yield per plant indicated their possibility of improvement with simple selection procedure in okra. Similarly, highly significant and positive correlation of fruit yield per plant with plant height, nodes per plant and fruits per plant was observed.
