Abstract

Eleven progenies of F3 generation of sunflower were selected for the character association study to assess the relationship among oil yield and its components. Observations were recorded on fourteen traits viz., days to first flowering, days to maturity, plant height, head diameter, powdery mildew percentage disease index, 100 seed weight, volume weight, seed yield, seed shape, seed colour, stripes on the margin, stripes between the margin, seed yield/plant, oil content and oil yield. Character association analysis revealed strong positive association of oil yield/plant with head diameter, 100-seed weight, seed yield and oil content. Hence, synchronized selection of these characters would contribute for the improvement of the oil yield/plant.
