Abstract: Variability studyconceded out using six genotypes of sacred basil in lieu of twenty-four characters. The assessmentsof variance showed greater phenotypic variance than genotypic variance because of impact of environment in the manifestation of all the studied characters. High range variation coefficients at genotypic and phenotypic levels for fresh herbage yield plant-1 (24.04%; 24.56%), fresh leaf (25.59%; 27.02%) yield plant-1, leaf oil yield (30.03%; 31.63%)signifying more variation manifested for these traits thus, more prospect for selection. Broad sense heritability assessments were high in conjunction through high genetic advancement on % mean basis for fresh herbage (95.59%; 48.37%) and fresh leaf (89.64%; 49.90%) yield plant-1 and leaf oil yield (90.15%; 58.73%) thus indicating the dominanceaction of additive genes prevailing in the inheritance and thus reliefs improvement over could done with simple selection techniques in sacred basil.
