С использованием семи маркеров к микросателлитным локусам, расположенным на хромосомах А- (Xgwm186, Xgwm291, Xgwm595) и В- (Xgwm371, Xgwm540, Xgwm554, Xgwm234) генома, изучен полиморфизм у 38 линий удвоенных гаплоидов и проведена оценка степени гомозиготности исследуемых линий. Полученные результаты свидетельствуют о наличии межлинейного полиморфизма по шести микросателлитным локусам. Обнаружено, что локус Xgwm554 не является полиморфным у исследуемых линий удвоенных гаплоидов. Наибольший полиморфизм отмечался для локусов Xgwm186, Xgwm291 и Xgwm595. По результатам кластерного анализа все исследованные линии распределились в три основных кластера, независимо от происхождения. Выделено восемь линий удвоенных гаплоидов, являющихся гетерозиготными как минимум по одному из исследуемых микросателлитных локусов. Показана возможность использования SSR-маркеров для оценки межлинейного полиморфизма и степени гомозиготности линий удвоенных гаплоидов тритикале, полученных методом индуцированного андрогенеза in vitro.</p></abstract><trans-abstract xml:lang="en"><p>We evaluated the rate of polymorphism of doubled haploid lines of hexaploid triticale obtained by the method of anther culture based on hybrids of spring and winter types. Using 7 SSR markers for the loci on the chromosomes A- (Xgwm186, Xgwm291, Xgwm595) and B- (Xgwm371, Xgwm540, Xgwm554, Xgwm234), polymorphism of 38 doubled haploid lines of hexaploid triticale was studied. Interlinear polymorphism along six microsatellite loci except the Xgwm554 locus, which is not polymorphic in the studied doubled haploid lines, was revealed. The highest polymorphism was observed for the Xgwm186, Xgwm291 and Xgwm595 loci. The cluster analysis showed that all studied lines were divided into three main groups. The origin of the lines did not affect the distribution in groups. This confirms the influence of in vitro culture somaclonal variation. Eight lines of doubled haploids, which are heterozygous for one of the studied microsatellite loci, were identified. We showed the possibility of using SSR markers to assess interlinear polymorphism and the homozygosity rate in the triticale doubled haploid lines obtained by the method of induced androgenesis in vitro.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>молекулярные маркеры</kwd><kwd>полиморфизм</kwd><kwd>гексаплоидное тритикале</kwd><kwd>линии удвоенных гаплоидов</kwd><kwd>гомозиготность</kwd></kwd-group><kwd-group xml:lang="en"><kwd>molecular markers</kwd><kwd>polymorphism</kwd><kwd>hexaploid triticale</kwd><kwd>double haploid lines</kwd><kwd>homozygosity</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена в рамках мероприятия 5 «Разработать биотехнологию гомозиготизации генома тритикале на основе андрогенеза in vitro и ДНК-маркирования и создать высокопродуктивный сорт» подпрограммы 1 «Инновационные биотехнологии–2020» ГП «Наукоемкие технологии и техника» на 2016–2020 годы.</funding-statement><funding-statement xml:lang="en">The work was carried out in the context of the scientific event 5 “To develop the homozygosity biotechnology of genome in the triticale on the basis of androgenesis in vitro and DNA marking and to make a highproductive grade” subprogramme 1 “Innovation biotechnologies–2020” GP “High technologies and technique” in 2016–2020.</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Гриб, С.
