Ее селекцией занимаются ведущие семеноводческие фирмы и научные учреждения мира. Для удовлетворения возрастающих запросов производства к качеству зерна важное значение имеет правильный подбор местных сортов и линий для гибридизации. Местные (как правило, гетерогенные) сорта – ценный исходный материал для создания самоопыленных линий, что способствует существенному расширению генетической базы используемых в селекции родительских форм. Достоинство сортов сахарной кукурузы и интерес к ним пищевой промышленности позволяют рассматривать генетические ресурсы коллекции Всероссийского института генетических ресурсов растений им. Н.И. Вавилова (ВИР) в качестве потенциально ценного исходного материала для селекции. Целью нашей работы было выявление дублетных образцов в коллекции сахарной кукурузы ВИР. В задачи исследования входило: проведение скрининга 19 местных сортов подвида сахарной кукурузы из коллекции ВИР с разным цветом зерна (9 стародавних местных с синей окраской зрелого зерна, 4 – с белой (бесцветной), 3 – с желтой и 3 – с красной окраской) по электрофоретическим спектрам зеина (белковым маркерам); изучение их биотипного состава и характера генетического полиморфизма, создание паспортной базы данных каждого изученного образца по белковым спектрам; для некоторых сортов, имеющих одинаковое сортовое название, но разные каталожные номера, установление степени идентичности их по биотипному составу с целью исключения дублетов. Электрофорез зеина проводили по стандартной методике ISTA, разработанной с участием отдела биохимии и молекулярной биологии ВИР, в вертикальных пластинах 10 % полиакриламидного геля. Методом электрофореза по спектрам зеина впервые исследованы сорта подвида сахарной кукурузы с разной окраской зерна. Для всех изученных образцов установлена уникальность спектров зеина, что позволяет идентифицировать их по специфичным для них маркерным компонентам. Результаты настоящей работы свидетельствуют о перспективности использования электрофореза зеина для выявления, идентификации и регистрации дублетных образцов в коллекции сортов подвида сахарной кукурузы ВИР.</p></abstract><trans-abstract xml:lang="en"><p>Of all the subspecies of Zea mays L. cultivated in the world, sweet maize is the most important for the global economy. The leading seed-growing companies and research institutions around the world are engaged in breeding this crop. To meet the increasing demands of the industry to grain quality, it is important to select appropriate local varieties and lines for hybridization. Local (usually heterogeneous) varieties are a valuable source material for creating self-pollinated lines that contribute to a significant broadening of the genetic base of parental forms used in breeding. The advantages of sweet maize varieties and the interest of the food industry in them make it possible to consider accessions from the maize collection of the N.I. Vavilov Institute (VIR) as a potentially valuable source material for breeding. The present research concentrated on 19 local sweet maize varieties with different grain colors from the VIR collection, that is, 9 varieties with the blue color of ripe grain, 4 with white (colorless) grain, 3 with yellow, and 3 with red. The research included an analysis of zein electrophoretic patterns (protein markers); a study of their biotype composition and the nature of genetic polymorphism, as well as the creation of a protein pattern database for each accession. For a series of accessions with the same varietal name, but different catalog numbers, the degree of their identity was determined from their biotype composition in order to exclude duplication. Zein electrophoresis was carried out in vertical plates of 10 % polyacrylamide gel according to the standard ISTA technique developed with the participation of the Biochemistry and Molecular Biology Department of VIR. Zein patterns were used for the first time to electrophoretically study sweet maize varieties with different grain colors. Unique zein patterns were established for all the accessions studied, which makes possible their identification by specific marker components. The results of this work characterize zein electrophoresis as a useful tool for the identification and registration of duplicate accessions in the VIR collection of sweet maize varieties.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>сахарная кукуруза</kwd><kwd>дублетные образцы</kwd><kwd>электрофорез зеина</kwd><kwd>белковые маркеры</kwd></kwd-group><kwd-group xml:lang="en"><kwd>sweet maize</kwd><kwd>duplicate accessions</kwd><kwd>zein electrophoresis</kwd><kwd>protein markers</kwd></kwd-group><funding-group xml:lang="en"><funding-statement>The present research was carried out within the framework of the State Assignment No. 0662-2019-006.
