С помощью метода ПЦР-ПДРФ проведен анализ частот аллелей и генотипов у кур породы корниш промышленной линии Г5 кросса «Смена-8». Использовали две пары праймеров, позволяющих получить ПЦР-продукт в участке гена миостатина. Рассмотрены две однонуклеотидные замены в экзоне 1 гена миостатина: G/A в положении MST2109 и G/С в положении MST2244. По частоте встречаемости обнаружено существенное преобладание в локусе MST2244 дезоксинуклеозидтрифосфата G над С и в локусе MST2109 – A над G. Различий по показателям продуктивности между генотипами при замене MST2109 обнаружено не было. При анализе аллельного разнообразия по локусу MST2244 обнаружены достоверные различия по живой массе цыплят в возрасте 7 дней между генотипами CC и G2G2 (p &lt; 0,01), CG2 и G2G2 (p &lt; 0,05). Особи с генотипом G2G2 (203,52 г) превосходили животных с генотипами СС (179,5 г) и CG2 (193,95 г) по живой массе в 7 дней. Выявлены различия между генотипами СС и G2G2 по живой массе в 33 дня (p &lt; 0,05). Таким образом, проведенные исследования позволили оценить частоту встречаемости аллелей в гене миостатина линии Г5 породы корниш. Установленные закономерности дадут возможность учитывать определенные генотипы кур по гену миостатина для ускорения селекционного процесса.</p></abstract><trans-abstract xml:lang="en"><p>The search for single nucleotide polymorphisms (SNP) in the myostatin gene is a promising direction of research as this gene is involved in the development of important biological and productive traits in chicken. Using PCR-RFLP technique, an analysis of allele and genotype frequencies in Cornish chicken breed of G5 line of Smena-8 cross has been conducted. Two pairs of primers allowing PCR product to be obtained in the myostatin gene have been used. Two single nucleotide substitutions on exon 1 of the myostatin gene have been under investigation: G/A in MST2109 and G/С in MST2244. A signifiant predominance of deoxynucleotide G in MST2244 over C and deoxynucleotide A over G in MST2109 has been observed. Differences in productive traits between genotypes in MST2109 were not detected. Analysis of allelic variability by MST2244 locus showed statistically significant differences in live weight at the age of 7 days between CC and G2G2 genotypes (p &lt; 0.01), CG2 and G2G2 (p &lt; 0.05). G2G2 individuals (203.52 g) were significantly heavier than CC (179.5 g) and CG2 (193.95 g) chickens at the age of 7 days. Statistically significant differences between the CC and G2G2 genotypes in live weight at the age of 33 days have been revealed (p &lt; 0.05). Thus, this research has led to a better understanding of allele frequencies in the myostatin gene in line G5 of Cornish breed. The results obtained will allow particular myostatin gene-based genotypes to be taken into account for accelerating the breeding process in the broiler poultry industry.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>куры</kwd><kwd>полиморфизм</kwd><kwd>ген миостатина</kwd><kwd>ПЦР-ПДРФ</kwd><kwd>аллель</kwd><kwd>генотип.</kwd></kwd-group><kwd-group xml:lang="en"><kwd>chicken</kwd><kwd>polymorphism</kwd><kwd>myostatin gene</kwd><kwd>PCR-RFLP</kwd><kwd>allele</kwd><kwd>genotype</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Дементьева Н.В., Терлецкий В.П., Тыщенко В.И., Яковлев А.Ф.
