Abstract: Present investigation “Correlation and path analysis of the Components of Yield in Sunflower Germplasm” was carried out during Kharifseason (2024-25) inRandomizedBlockDesignatBotanyResearchfarm, CollegeofAgriculture, Pune.Sunflower (Helianthus annuus L.) is an oilseed crop valued for its high content of polyunsaturated fatty acids, particularly linoleic and oleic acids, which contribute to cardiovascular health by lowering cholesterol levels. The primary objective in sunflower breeding is to develop cultivars with high yield. 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. The study included 32 genotypes including 2 checks. Correlation study reported highly significant positive association of seed yield per plant with seed filling percentage, followed by head diameter, and 100 seed weight and negative association with hull content at genotypic level. Among the characters studied seed filling percentage had the highest positive direct effect on seed yield per plant followed by head diameter and genotypic correlation between hull content and seed yield per plant was strongly negative, while its direct effect was positive at genotypic level. Therefore, direct section for characters seed filling percentage and head diameter would be useful in developing high yielding genotypes in sunflower.
