For designing efficient breeding procedure adequate information on the genetic structure of the parents and mode of gene action affecting the yield and its related traits are prerequisite for progress in breeding. The objective of this research was to evaluate heritability, components of genetic variance as well as ratio of dominant and recessive genes in parental genotypes of sunflower. The plant material selected for this research consisted of sunflower genotypes distinguished by important characteristics for the production of sunflower. Quantitative traits evaluated in this study were seed yield/plant, oil content, 1000 seed weight, head diameter and plant height. Presented results showed significant variability of evaluated quantitative traits. Phenotypic variance was higher than genotypic demonstrating strong environment effect in expression of evaluated traits. The values of broad sense heritability for evaluated traits were very high for plant height, high for 1000 seed weight, ...moderate for seed yield/plant and head diameter, while low for oil content.
