Genetic variability and trait association analysis in okra (Abelmoschus esculentus L. Moench)
2015
Ishfaq, M.
Association among different traits of 25 okra genotypes was ascertained to understand the direct and indirect contributions of plant traits with pod yield per plant which may help to develop high yielding okra varieties. The 25 genotypes of okra were sown in a field using randomized complete block design with three replications during the summer season 2014. The data for fruit yield, first flowering node, days to 50% flowering, number of pods per plant, plant height, number of internode, node(s) producing fruit on the main stem, stem diameter, number of seeds per pod, 100-seed weight, pod length at maturity, pods weight per plant and yield per plant were recorded and statistically analyzed for estimating genetic variability, direct and indirect effects of these characters on pod yield. All traits showed significant association with pod yield except first flowering node and stem diameter at maturity. Path analysis revealed that pod weight per plant, number of pods per plant, plant height at maturity and 100 seed weight contributed largely to okra pod yield and maximum emphasis would be given to these traits for selection focused at development of high yielding okra varieties.
