The primary objective in sunflower breeding is to develop cultivars with high yield. Achene yield in sunflower is a complex trait, influenced by various component traits and environmental factors. Understanding the traits interaction among themselves and with the environment is very essential in planning successful crop improvement program. Present investigation “Correlation and path analysis in advanced inbred lines of Sunflower” was carried out during 2017-2018. The study included 117 advanced inbred lines and 4 checks. Correlation study reported highly significant positive association of seed yield per plant with plant height (0.942; 0.933) followed by head diameter (0.852; 0.818), 100 seed weight (0.243; 0.217) and days to 50 % flowering (0.238; 0.219) in sunflower at both phenotypic and genotypic level, respectively. Among the characters studied plant height (0.933; 0.929) had the highest positive direct effect on seed yield per plant followed by volume weight (0.042; 0.046), head diameter (0.024; 0.040) and days to maturity (0.0124; 0.023) at both genotypic and phenotypic level. Therefore direct section for early maturing with tall stature and larger head would be useful in developing high yielding genotypes in sunflower.
