Correlation study for oil yield in sunflower (Helianthus annuus L.)

Abstract

Seventy nine inbred lines of sunflower were selected for the character association study to assess the relationship among oil yield and its components. Observations were recorded on eight traits viz., days to 50% flowering, plant height (cm), head diameter (cm), 100-seed weight (g), volume weight per 100 ml (g), oil content (%), seed yield per plant (g) and oil yield per plant (g). Character association analysis revealed positive and significant association of oil yield per plant with seed yield per plant, plant height, head diameter, volume weight, 100-seed weight and oil content. Hence simultaneous selection of these characters would contribute for the improvement of oil yield per plant.
