In order to study of the cause and effect relationship among some morphological and agronomic traits of 19 populations of fennel (Foeniculum vulgare Mill.), an experiment was conducted based on randomized complete block design with 3 replications in 2012 at the Research Station of Faculty of Agriculture, University of Tabriz, Iran. Correlation coefficients showed that grain yield had a positive correlation with number of umbel, number of seed per umbel, harvest index, essential oil content and length of first internode. Foeniculum-vulgarePath analysis using stepwise regression indicated that number of umbel had the most direct and positive effect on grain yield. Therefore, these traits could be used as effective factors to increase grain yield in fennel breeding programs. The studied populations were classified in to two groups with distinct differences for grain yield and the traits which were confirmed to be related to grain yield.
