Abstract: The experimental material comprised of 60 multihead inbred lines of sunflower (Helianthus annuus L.) and one check SS-2038 had evaluated at oilseeds research station, Latur during the kharif 2017 in a randomized block design with two replications. Observations were recorded for twelve characters viz., days to 50% flowering, days to maturity, plant height, head diameter, no of branches per plant, seed filling percentage, hull content percentage, Seed yield per plant, 100 seed weight, oil content, pollen production per plant and volume weight per plant etc. Correlation studies indicated that head diameter, seed filling per cent 100 seed weight and pollen production per plant had significant positive association with seed yield. Path coefficient analysis revealed that high positive direct effect of days to 50% flowering, plant height, head diameter, no of branches per plant, seed filling (%), hull content (%), 100 seed weight (g), volume weight (g) with yield. Therefore simultaneous selection for these traits is suggested for improvement of seed yield in sunflower.
