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 2012. Genetic variability were carried out to study characters 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. The study revealed that highest genotypic and phenotypic coefficient of variance observed for number of branches per plant, fruit length, yield per plant and reaction to yellow vein mosaic virus. Highest estimates of heritability were recorded for yield per plant followed by fruit weight and reaction to yellow vein mosaic virus. Highest genetic advance was observed for number of branches per plant followed by number of ridge per fruit, yield per plant, fruit length and reaction to yellow vein mosaic.
