Research of the peculiar features of correlation parameter of production indices of 870 mongrel inbred sheep with the various inbreeding coefficients was realized in the conditions of the Republic of Belarus. In course of study there was stated the one-sided influence of inbreeding on phenotypic indices of pair, individual and cumulative pair correlation genetic correlations of sheep productivity. The majority of them were the statistically authentic values with P less than 0,1 - 0,001. It was stated that coefficient variability of genetic correlation of wool productivity rendered influence on sheep inbreeding degree among which there were marked off animal units with inbreeding in degree of consanguinity with the coefficients of higher statistical confidence (with P less than 0,01 - 0,001) than animal units with degrees of close or low relationship and outbred animal units - (P less than 0,1 - 0,01). The majority of ewe productive quality correlation factors with a different inbreeding degree proved to be positive and authentic and could be used for an estimation of correlations between traits in selection process for population perfection
