Abstract

IVANOVA, P., L. VELKOVA-JORDANOSKA and I. DOBROVOLOV, 2006. Genetic divergence among the populations of B. petenyi from Eleshnitza River (Bulgaria) and some tributaries of Vardar River (Macedonia). Bulg. J. Agric. Sci.,12: 290-296

Genetic-biochemical study on barbus (B. petenyi} from Eleshnitza River (Bulgaria) and some tributaries of Vardar River (Macedonia) are carried out. Thirteen loci are analyzed and polymorphism on three of them was found. On the base of genetic distances (DNei) calculated barbus species from Eleshnitza River and some tributarities of Vardar River (Treska, Bregalnitza and Orizarska) belong to two different subspecies. Comparative genetical analyses on B. petenyi from Bulgarian and Macedonian Rivers with B. meridionalis and B. pelopenesius are needed to specify while in the investigated area B. petenyi exactly exist or it is presented form some hybrid population.

Key words: barbus, electrophoresis, isoelectric focusing, genetic distances
