Abstrakt: Establishing genetic diversity in a population is critical to developing an effective breeding program. Assessment of a source collection of Vicia faba species, represented by 12 genotypes of introduced origin, showed a slight variation regarding vegetation period longevity (CV=5.92%), plant height (9.23%), and pod width (10.45%), and medium variation for the first pod height (14.42%) and 100 seed mass (17.21%). Traits that contributed at the greatest degree to genetic diversity in faba bean genotypes were seeds number (29.88%) and seed weight (25.26%) per plant, pods number (23.14%) and pod length (22.02%). The variability was also strong in terms of plastid pigment content.nThe studied genotypes were distributed in three clusters, genetically distant to a different degree. For the development of new promising forms, with increased productivity and a shorter vegetation period, suitable for inclusion in hybridization schemes were BGE 002106, Fb 1903, Fb 1929 and Fb 2481.
