Increasing seed yield and oil content is one of the most important goals in sunflower (Helianthus annuus L.) breeding programs. The aim of any plant breeder includes selection from natural population or artificially developed for one or several characters. In the present investigation, twenty sunflower hybrids were evaluated for various parameters under field conditions to estimate genetic parameters, correlation coefficient and path analysis. Analysis of variance and mean performance for yield and its components revealed significant differences among all the genotypes for all the characters. Results revealed highly significant differences among all the hybrids. Higher PCV and GCV were obtained for seed yield per plant followed by head diameter and test weight. Moderate PCV and GCV were obtained for the characters viz., plant height, volume weight and oil content, while low PCV and GCV were observed for days to 50% maturity and days to 50% flowering High value of heritability coupled with the high genetic advance was estimated for plant height, test weight, seed yield per plant, volume weight and head diameter, high heritability coupled with moderate genetic advance was recorded for days to 50 per cent flowering and oil content indicated additive gene action controlling these traits. Highly significant positive correlation was estimated between seed yield per plant with plant height, volume weight and head diameter and significant positive association with test weight but the association between seed yield and days to maturity was negative and low.
