In articleshowed results of studies differentiation interline New Zealand White breed rabbits by C34T myostatin gene and G2464A progesterone receptor gene polymorphism. The highest frequency of allele C by myostatin gene had the offspring from male Emperor (0.551). The frequency of allele T in this sample was 0.449 respectively. For rabbits lines Bilash was observed higher values G allele of the progesterone receptor gene (0.488) due to the benefits of homozygous animals. Established distribution of the effective number of rabbits alleles (Ne) by polymorphic variants of the myostatin gene and progesterone receptor gene. Identify indicators of genetic diversity, analyzed genetic distance matrix and indices of relationship in the context of linear accessory studied animals. Proposed methodology for selection of different lines rabbits by polymorphic variants of the myostatin gene and breeding values according to the algorithms of the best unbiased linear prediction. According to the BLUP-evaluation of the New Zealand White breed rabbits of different genotypes progeny established that high index values were males of the line Nazar (+0.199), Baikal (+0.357) and Casper (+0.046). They answered the relative breeding value: 101.0% 100.0 % and 100.5%, respectively. BLUP-analysis assessing the breeding value of the New Zealand White rabbits breed by reproductive traits daughters showed that a high index of BLUP had male Nazar (0.140) and lowest Caesar (-0.035). Based on these studies suggested using of integral genomic and BLUP evaluation of rabbits, which is the basis for identifying the genetic potential of animals and forecast productive qualities offspring.
