Seed storage proteins of 7 landrace accessions of four vetch (Vicia) species collected in Turkey were analyzed by SDS-PAGE. The protein bands of the genotypes were scored for their absence and presence and used for estimating genetic distances which were utilized for a similarity matrix analysis. The genotypes of Vicia spp. showed genetic similarity values that ranged from 33 to 83 percent. The genetic diversity exhibited by seed proteins was illustrated by a similarity matrix and the UPMGA dendogram. Although the Vicia genotypes showed different seed protein patterns those of V. pannonica, V. narbonensis, V. sativa and V. villosa formed the same UPMGA cluster. Consequently, it is shown that SDS-PAGE is of no value to predict taxonomic relationships of selected genotypes because Vicia genotypes have very similar protein patterns, at the same time revealing considerable differentiation in some vetch species (V. villosa and V. pannonica).
