Nuclear DNA contents, automated karyotype analyses, and
sequences of internal transcribed spacers from ribosomal genes have been
determined in the species belonging to section Hypechusa of the subgenus
Vicia. Karyomorphological results and phylogenetic data generated
from the comparison of rDNA (genes coding for rRNA) sequences
showed that sect. Hypechusa is not monophyletic; however, some monophyletic
units are apparent (one including Vicia galeata, V. hyrcanica,
V. noeana, and V. tigridis, another including V. assyriaca, V. hybrida,
V. melanops, V. mollis, and V. sericocarpa), which partly correspond to
morphology-based infrasectional groups. The relationships among these
species and the species in sections Faba, Narbonensis, Bithynicae, and
Peregrinae have been also investigated.
