Nineteen accessions collected from farmers' fields and two commercial cultivars (Giza 2 and Giza 402) of faba beans Vicia faba L. were evaluated during the 1986 and 1987 seasons. Some of the collected accessions were superior than both commercial cultivars in all the characters studied. The environmental variance exceeded the genetic variance for all traits. Heritability reached 16.87, 33.33, 44.90, 44.70, and 39.36% for plant height, number of branches, number of pods/plant, seed yield/plant, and 100-seed weight, respectively. Both phenotypic and genotypic correlations among traits showed positive relationship for seed yield/plant with number of branches and number pods/plant, and also between plant height and number of pods/plant. However, seed yield/plant was negatively correlated with plant height. Path coefficient analysis revealed that number of pods/plant had the highest positive direct effect on seed yield/plant, followed by 100-seed weight and number of seeds/pods
