[RAPD-analysis of duck genetic polymorphisms. Interlineal differences in a Peking duck species].

The possibility of using RAPD markers for the detection of differences between lines of Peking duck constituting a local population maintained at the Blagovarskii State Farm for Pedigree Poultry was demonstrated. Genetic distances based on the RAPD markers precisely and accurately reflect even small changes that occurred in the genetic structure of Peking duck lines during breeding of parental forms. The pattern of inheritance of RAPD markers obtained using primer HM13 was studied in the F1 progeny of two families. The results can be used for improvement of available high-productivity lines of ducks breeding of new lines, and promotion of the combining abilities of lines.
