Behaviour of some exotic sunflower germplasm lines and inbred lines was compared through path analysis in two separate experiments. Experiment-I comprised ten genetically diverse inbred lines while experiment-II contained ten genetically different germplasm lines. Estimates of genotypic correlation coefficient tended to be larger than their corresponding estimates of phenotypic correlation coefficients. A few genetic correlations were, however, found to be significant in both experiments. Path coefficient analysis revealed that 100-achene weight followed by oil contents had strong direct effect on yield in Experiment-I. In experiment-II, days to complete flowering exhibited greater effect on yield.
