rDNA Loci and DAPI Bands Reflect the Phylogenetic Distance between Vicia Species

The chromosomal positions of 5S and 25S rRNA genes, as well as of DAPI (4′,6-diamidino-2-phenylindole) bands are described for 5 Vicia species (Vicia macrocarpa, Vicia sativa, Vicia narbonensis, Vicia ervilia and Vicia faba) to find out the phylogenetic relationships among studied species. From the results, it was concluded that the phylogenetic relationships among the studied species are as follows: Vicia ervilia is closely related to Vicia narbonensis and Vicia narbonensis is related to Vicia macrocarpa. However, the degree of relation between Vicia narbonensis, and Vicia macrocarpa is less than the relation between Vicia narbonensis and Vicia ervilia, while Vicia sativa is closely related to Vicia macrocarpa, but Vicia faba is far from all studied species.
