Цель исследований – разработка модельных генетических профилей по генам-маркерам количественных признаков продуктивности свиней плановых материнских пород, используемых в племенном свиноводстве. В Республике Беларусь такими породами являются: белорусская крупная белая, белорусская черно-пестрая и йоркшир. Исследования проводили в сельскохозяйственном филиале «СГЦ «Заднепровский» ОАО «Оршанский комбинат хлебопродуктов», ОАО «СГЦ «Заречье», ОАО «СГЦ «Западный» на популяциях чистопородных животных пород белорусской крупной белой, белорусской черно-пестрой и белорусского заводского типа свиней породы йоркшир в течение 2002–2018 гг. Генетическое тестирование проводили на свиноматках, хряках и откормочном поголовье свиней материнских пород. В качестве исходного материала использовали пробы ткани из ушной раковины свиней, из которых выделен и оптимизирован ДНК для анализа полиморфизма генов методом ПЦР – ПДРФ в лабораториях молекулярной биотехнологии и ДНКтестирования (Научно-практический центр НАН Беларуси по животноводству) и генетики животных (Институт генетики и цитологии НАН Беларуси). В результате исследований на основании установленного полиморфизма разработаны модельные генетические профили свиней материнских пород по генам-маркерам количественных признаков продуктивности. Максимально достигнутый уровень предпочтительного генотипа по каждому гену-маркеру среди трех материнских пород послужил модельным профилем для оцениваемых пород (племенного молодняка). Для пород с установленным высоким уровнем полиморфизма гена-маркера и продуктивности разработан модельный профиль, превышающий достигнутый показатель на 8–10 п.п.</p></abstract><trans-abstract xml:lang="en"><p>Currently, development of molecular genetics and biology allows for genomic analysis and selection directly at the DNA level (marker-dependent selection). The aim of the research was to develop model genetic profiles for marker genes of quantitative traits of productivity of pigs of planned maternal breeds used in pig breeding. Such breeds in the Republic of Belarus are as follows: Belarusian large white, Belarusian black and white and Yorkshire. The studies were carried out at the agricultural branch of Zadneprovsky SGC, Orshansky Plant of Bread Products, JSC, Zarechye SGC, Zapadny SGC with populations of purebred animals of Belarusian Large White, Belarusian Black and White and Belarusian plant type of Yorkshire pigs during 2002-2018. Genetic testing was carried out with sows, boars and finishing pigs of maternal breeds. As a starting material, tissue samples from the auricle of pigs were used with DNA isolated and optimized for the analysis of gene polymorphism using PCR - RFLP method in the laboratories of molecular biotechnology and DNA testing (Research and Practical Center of the National Academy of Sciences of Belarus for Animal Breeding) and animal genetics (Institute of Genetics and Cytology of the National Academy of Sciences of Belarus). As a result of studies based on the established polymorphism, model genetic profiles of maternal breeds of pigs were developed for marker genes of quantitative traits of productivity. The maximum achieved level of the preferred genotype for each marker gene among the three maternal breeds served as a model profile for the evaluated breeds (breeding young animals). For breeds with an established high level of marker gene polymorphism and productivity, a model profile has been developed that exceeds the achieved indicator by 8-10 p.p.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>селекция</kwd><kwd>белорусская крупная белая</kwd><kwd>белорусская черно-пестрая породы свиней</kwd><kwd>белорусский заводской тип свиней породы йоркшир</kwd><kwd>воспроизводительные</kwd><kwd>откормочные и мясные качества</kwd><kwd>генетическое тестирование</kwd><kwd>полиморфизм</kwd><kwd>гены-маркеры</kwd><kwd>генетические профили</kwd></kwd-group><kwd-group xml:lang="en"><kwd>breeding</kwd><kwd>Belarusian large white</kwd><kwd>Belarusian Black and White breed of pigs</kwd><kwd>Belarusian plant type of Yorkshire breed of pigs</kwd><kwd>reproductive</kwd><kwd>fattening and meat traits</kwd><kwd>genetic testing</kwd><kwd>polymorphism</kwd><kwd>marker genes</kwd><kwd>genetic profiles</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">Лобан, Н.А.
