Correlation for oil yield in sunflower (Helianthus annus L.)

Fifty five hybrids of sunflower were selected for the character association study to assess the relationship among yield and its components. Observations were recorded on nine traits viz., 50% flowering, days to maturity, plant height, head diameter, 100-seed weight, volume weight, oil content, oil yield per plant and seed yield per plant. Character association analysis revealed strong positive association of oil yield per plant with days to maturity, 100_seed weight, volume weight, oil content and seed yield per plant. Hence simultaneous selection of these characters would contribute for the improvement of the oil yield per plant.
