Genetic analysis of 10 loci was carried out in faba bean (Vicia faba L.). Close genetic linkage (p = 0.19 +- 0.04) was detected between Sdp/sdp locus and the Yg/yg locus. Recombination frequency for Sc/sc locus and N/n locus was 0.44 +- 0.04, indicating that both loci could be linked. An epistatic action of the Sc allele on the hilum color gene was found. Recombination values for all the remaining dihybrid segregations tested indicated independent assortment for all combinations. The recessive alleles for yellow pigment in the flower (yfyf) had an epistatic effect on the dominant allele of the Sc locus
