To evaluate the genetic diversity of some Vicia species, seed proteins of 160 accessions (30 of Vicia faba, 15 of V. narbonensis, 82 of V. sativa and 25 of V. ervilia and 8 accessions of other Vicia species) were analysed by sodium dodecyl sulphate polyacrylamide gel electrophoresis (SDS-PAGE). The dendrogram showed that the two outcrossing species V. faba and V. villosa were the most distant among all species (average percent disagreement value PDV 0.47 and 0.45, respectively). The tree was divided into small clusters of two species each. V. narbonensis fell in one cluster with V. michausai (at PDV = 0.35) and V. lutea (var. hirta) fell in one cluster with V. serococorpes (at PDV = 0.32) whereas, V. ervilia fell in one cluster with V. sativa (at PDV = 0.27). The V. sativa subspecies, however, were closely related (PDV < 0.1). In general, this study did not prove any relationship between the studied storage proteins and the geographical distribution or ecological needs of the studied accessions.
