Abstract
Automated karyotype analyses and sequence of
rDNA spacers have been analysed for the species belonging
to sections Atossa, Microcarinae, Wiggersia and Vicia.
Karyomorphological parameters, based on Rec, Syi and TF
% indices, have been determined and evidenced that, in
term of symmetry, the karyotype of Vicia lathyroides was
the most asymmetric one. A multivariate analysis using 34
karyological parameters, in addition to the symmetry
indices, has been carried out and the corresponding
dendrogram of linkage distances showed six different
groups. Molecular investigations on the inclusive group in
study by employing ITS DNA sequences indicated a
different pattern of relationships. The cladistic analysis
combining the molecular data set with karyological parameters
evidenced that the species of sections Vicia and Atossa
join closely to each other in a paraphyletic group, which
includes the monophyletic section Wiggersia. Therefore,
our karyological and molecular data provide information
about the phylogenetic position of the analysed species
inside the subgenus Vicia and are discussed in relation to
previous results obtained by morphology, isozymes and
ribosomal genes analyses.
