Vicia esdraelonensis, a rare taxon belonging to section Hypechusa of subgenus Vicia, was recovered and analyzed by cytological, karyological, and molecular methods, with the aim of both characterizing this species and furthering our knowledge of the phylogeny of subgenus Vicia. Automated karyotype analysis, nuclear DNA content, and chromatin organization were determined by the Feulgen reaction, as well as chromosome banding after double staining with 4',6-diamidino-2-phenylindole (DAPI) and chromomycin A3. The chromosome number and the nuclear DNA content were in agreement with the values of the species of section Hypechusa. The GC- and AT-rich preferential sites were determined by chromomycin A3 and DAPI staining. Karyomorphological parameters indicated that V. esdraelonensis is in an intermediate position in the spatial representation of the species of section Hypechusa on the basis of symmetry indices, as well as in the dendrogram of linkage distance constructed on 37 chromosome parameters. Molecular data based on internal transcribed spacer sequences show that V. esdraelonensis can doubtlessly be included in section Hypechusa and document its closeness to V. noeana. A cladistic analysis combining the molecular data set with karyological characters is also reported. Karyological, cytological, and molecular data allow characterization of the V. esdraelonensis genome and provide information about the phylogenetic position of this species within the Hyrcanicae series of section Hypechusa.
