Results of a preliminary karyological study of bulgarian populations ofVicia hirsutaandV. meyeriare reported. Diploid chromosome number 2n= 2x=14 was observed in all populations studied. The karyotypes of the two species are characterized by quite similar chromosome types and a high level of symmetry. Along with that, certain differences are evident. The karyotype ofV. meyericonsists of slightly longer chromosomes. Most obvious difference is observed in the SAT-chromosome pair morphology; inV. hirsutait possesses a smaller satellite attached to the short arm; inV. meyerithe satellite is considerably larger than that inV. hirsuta.It is equal in length to the shorter arm, from which it is separated by a secondary constriction.
