Abstract

Fifty seven lines of okra including ten different genotypes along with forty five hybrids and two standard checks were evaluated in Randomized Block Design with two replication in Kharif 2011. Correlation and Path analysis were carried out to study character association and contribution for days to 50 per cent flowering, Plant height at harvest, number of branches per plant, number of nodes per plant, days to first picking, number of fruits per plant, average length of fruit, average weight of fruit, yield per plant (g), yield per plot (kg), yield per hectare (qt) and reaction to yellow vein mosaic for identification of appropriate selection indices. Genotypic and phenotypic correlation revealed that at both level fruit yield was positively associated with number of fruits, number of nodes per plant, fruit length and fruit weight. Correlation and Path analysis revealed that characters days to first picking, plant height at harvest, number of nodes per plant and number of fruits per plant not only had positive significant association with yield per plant but also had high positive direct effects on marketable yield per plant and are regarded as the main determinants of yield per plant. If selection is based on these characters then improvement in yield will be efficient.
