ABSTRACT The present experiment was conducted with twenty germplasms of ocimum at College of Horticulture, Mandsaur, Madhya Pradesh in Randomized Block Design with three replications during the year 2019-20. This investigation revealed that, the phenotypic coefficient of variation was greater than the genotypic due to environmental effects on the expression of the characters. The more GCV was observed for essential oil in reproductive phase (44.28%) followed by essential oil in vegetative phase (43.00%). The maximum PCV observed for essential oil in reproductive phase (44.55%) followed by essential oil in vegetative phase (44.11%). The maximum heritability was observed in fresh weight (99.14%), genetic advance was in leaf area (4453.51) and genetic advance as percent of mean in essential oil at reproductive phase (90.41). Seed yield quintal per hectare was indicated significant and positive correlation with most of the traits. In genotypic and phenotypic path coefficient analysis all the parameters were shown positive significant direct effect on seed yield.
