The study on direct and indirect effects of seventeen different growth, physiological and fruit related traits on yield of okra had revealed the presence of very high direct positive effect of fruit number on yield plant-1. The traits viz., number of fruits plant-1, plant height and fruit weight were identified as the important yield determinants through path co-efficient analysis and these traits could be relied upon for selection of high yielding genotypes in okra. Leaf area index was found to be the second ranking trait with high positive direct effect followed by stem diameter. The indirect effect of fruit length as well as fruit girth on yield through fruit weight were also found to be positive, indicating their importance in exercising selection.

Study of thirty three diverse genotypes of okra revealed the presence of high variability, for primary branches at flowering, internodal length, leaf area index, mucilage content, seed number and hundred seed weight. The traits viz., days to flowering, plant height, primary branches at flowering, internodal length, relative water content, mucilage content, crude fibre content, pedicel length, fruit length, fruit girth, fruit weight, seed number and hundred seed weight were found to be highly heritable and hence, could be considered while selection. High heritability with high genetic gain observed for plant height, primary branches at flowering and internodal length indicate the predominance of additive genes, while high heritability with low genetic gain observed for days to flowering indicate the role of non-additive gene action.
