Abstract


Genotypic and Phenotypic correlations among seed yield and 10 component characters were studied in 65 genotypes (15 parents and 50 crosses) of sunflower (Helianthus annuus L.). Pooled analysis of parents and crosses revealed that head diameter. leaves per plant, hundred seed weight and stem girth had significant and positive correlations with yield. Head diameter. stem girth. hundred seed weight, number of leaves and oil content had significant and positive intercorrelation among themselves. Head diameter, days to first flowering and number of leaves influenced the yield directly. Improvement of this crop through the component traits is significant.
