Character Association and Path Analysis for Yield and Yield Attributes in Sunflower (Helianthus Annuus L.).

Character association and path analysis between yield and its contributing traits were studied in 71 genotypes (15 parents, 54 hybrids and two checks) of sunflower. Analysis of variance revealed that existence of significant differences among genotypes for all the characters studied. Seed yield was significant positively correlated with number of filled seeds per head, head diameter, hundred seed weight, seed filling per cent and plant height. Path coefficient analysis indicated that highest direct effects on seed yield were observed in the traits, number of filled seeds per head and hundred seed weight and hence emphasis can be laid out on these traits during selection for further improvement in seed yield in sunflower.
