The article presents the results of the analysis of association between the economic useful traits and ISSR-PCR markers of Romanov sheep breed. For the first time, the impact of the genetic structure represented by anonymous sequences flanked by inverted repeats of microsatellite loci on the variability of phenotypic traits is found. Using F-test, reliable relationship with several ISSR-PCR markers was determined for 9 traits of productivity. In addition, correlations between of selected economic useful traits and the influence of factors such as sex, population origin and breeding line were studied. Using the method of Pearson's correlation coefficient, significant correlation between productivity characters (live weight, wool yield, wool density, average fertility and others) is identified.

Keywords:Romanov breed, ISSR-PCR, sheep genetics, genetic structure, economic useful traits, F-test, Pearson’s test
