Correlation study in sunflower was carried-out for yield, yield components and other morphological traits in nine sunflower hybrids at Agriculture Research Institute Tarnab, Peshawar during Kharif 1998. The grain yield was positively and significantly correlated with plant height, head diameter and oil content both at genotypic and phenotypic levels. Seeds per head showed a positive significant association with grain yield at both genotypic and phenotypic levels. Plant population per m- showed significant positive relationship at genotypic level.
