In this survey, 30 spring safflower genotypes were tested via the randomized complete block experiment design for two years of 2005 and 2006. The phenotypic correlations among the traits and their path coefficient were estimated in both years. Grain yield was significantly correlated with some characters, like the plant height (r = 0.563** and r = 0.536**), hectoliter weight (r = 0.574** and r = 0.577**) and biological yield (r = 0.980** and r = 0.977**) in 2005 and 2006, respectively. Path coefficient analysis revealed that plant height, hectoliter weight and 100-seed weight had the highest positive direct effects on grain yield in 2005 and 2006, respectively. Therefore, improvement of the grain yield will immensely be efficient via plant height, hectoliter weight and 100-seed weight based selection. ER -
