Present experiment was conducted on 32 sunflower genotypes (11 CMS lines and 21 Restorer lines) on the basis of their diverse origin, growth habit, phenology and adaptation with an object to assess variation in oil yield attributing traits. The total variability consisting heritable and non-heritable components of the characters were estimated by genotypic (GCV) and phenotypic (PCV) coefficient of variation, heritability and genetic advance (GA) and the best positive traits for sunflower improvement through selection and breeding were assessed.
