The present study was carried out to investigate a path coefficient with one faba bean cultivar i.e. Filiz 99 and two advanced breeding lines i.e. H1=PN 55 K. No 584-066 Reine Blance and H2 PN 54 K. No 7954 x 964-92B. Relationships between yield and yield components were determined by using a correlation and a path-coefficient analysis in 1999-2000. In the investigated characters positive and significant relationships were found statistically between grain number pod and pod number plant-1; between biological yield and plant height; between biological yield and grain number pod-1. Direct and indirect effects of plant height, pod length, first pod height and pod number plant-1 and grain number pod-1 upon biological yield were calculated. The total determination coefficient was found as 0.636 (63.6%) in the model which we used.
