Abstract: The experiment was conducted at the experimental station of Sids Research station, Bini Sueif Governorate, during 2010/11, 2011/12 and 2012/13 under insect free cage. Three F2 faba bean populations and their four parental varieties were evaluated for seed yield and five related components traits. Highly significant variation was noted for all the studied traits. The tree F2 populations recorded the higher values than parental ones for all the traits except hundred seed weight, which recorded the least value. High heritability estimates were observed for all the traits except hundred seed weight. In general phenotypic coefficients of variability were greater than their corresponding genotypic coefficient of variability. Higher estimates of heritability coupled with genetic advance were observed for number of seeds per plant, seed yield and number of pods per plant indicating that these characters are mainly controlled by additive genes and selection of such traits may be effective for the improvement of seed yield. All the studied traits had positive and highly significant genotypic and phenotypic correlations with seed yield except hundred seed weight that showed negative and highly significant one. Results showed that number of seeds per plant; number of pods per plant and plant height had the most direct or indirect effect on seed yield. Hence, these traits could be used for the improvement of seed yield resulting in the development of high yielding populations of faba bean.
