The present investigation was carried out to assess the relationships among seed yield and its contributing traits in 40 diverse genotypes of Sunflower (Helianthus anuus L.). The genotypes were evaluated under a randomized block design with two replications at the Research farm, Oilseeds Research Station, Latur, VNMKV Parbhani (Maharashtra) during Kharif season 2024-25. Observations were recorded on ten quantitative traits including days to 50 per cent flowering, days to maturity, plant height (cm), head diameter (cm), Seed filling (%), 100 seed weight (g), volume weight (g/100ml), hull content (%), seed yield per plant (g) and oil content (%). Days to 50 per cent flowering and days to maturity observations were recorded on plot basis only once.

Plant height, head diameter, seed filling percentage and oil content recorded highly significant positive correlation with seed yield per plant at both phenotypic and genotypic levels and days to 50 percent flowering and days to maturity recorded significant negative correlation with seed yield per plant. Path coefficient analysis at both phenotypic and genotypic level indicated that the traits plant height, head diameter, seed filling percentage and volume weight exerted a positive direct effect on seed yield per plant.
