146 genotypes including 46 mutant and 100 segregants of sunflower were selected for the character association study to assess the relationship among yield and its components. Observations were recorded on six traits viz., 50% flowering, days to maturity, plant height, head diameter, 100-seed weight and seed yield per plant. Character association analysis revealed strong positive association of head diameter and 100-seed weight with seed yield per plant Hence simultaneous selection of these characters would contribute for the seed yield per plant improvement. And this association study revealed the need of development of early and dwarf mgenotype for improvement of seed yield per plant.
