В качестве компонента функционального питания  перспективна кукуруза с «нетрадиционным» составом зерна (восковидная, масличная, сахарная, опак и другие фенотипические варианты). К формированию восковидного эндосперма с высоким содержанием амилопектина приводят мутации гена waxy, нарушающие структуру и функцию фермента биосинтеза амилозы. Рецессивная природа мутаций гена waxy не позволяет проводить фенотипический отбор гетерозиготных носителей в гибридной популяции. Высокая частота и гетерогенная природа мутаций, нарушающих биосинтез амилозы, затрудняют однозначную идентификацию молекулярной природы возникших генетических изменений. Известно, что внутри нетранслируемых участков гена waxy присутствуют микросателлитные повторы. Задача настоящего исследования – оценить эффективность использования микросателлитных последовательностей локуса waxy для идентификации и маркирования генотипов восковидной кукурузы. Для ее решения было проанализировано содержание крахмала, короткоцепочечных растворимых углеводов, амилозы, амилопектина в зерне 33 образцов кукурузы. Идентифицированы группы образцов со сходным углеводным со ставом эндосперма, в том числе 13 высокоамилопектиновых об разцов, носителей мутаций гена waxy (wx), и 20 образцов с фенотипической нормой признака (Wx). Молекулярно-генетический скри нинг образцов коллекции включал анализ полиморфизма микросателлитных локусов phi022, phi027, phi061, ассоциированных с последовательностью гена waxy. Аллельный состав отдельных локусов и их сочетаний соотнесен с накоплением запасных углеводов в эндосперме зерна. Дифференцировать группы образцов кукурузы с диким Wx и мутантным фенотипом wx позволил только анализ сочетания аллелей локусов phi022 и phi027 либо комплекса всех трех маркеров. Таким образом, для маркер-ассоциированного отбора образцов кукурузы с высоким накоплением амилопектина в эндосперме могут представлять интерес не отдельные аллели локусов phi022, phi027, phi061, а их уникальные сочетания.</p></abstract><trans-abstract xml:lang="en"><p>As a component of functional nutrition, maize cultivars with “non-traditional” kernel composition (waxy, oilbearing, sugar, opaque, etc. phenotypic variants) are promising. Mutations in the waxy gene, which break down the structure and function of the enzyme for amylose biosynthesis, lead to a waxy (with a high content of amylopectin) endosperm formation. High variability of the waxy gene limits the use of microsatellite loci in marker associated selection of waxy maize genotypes. The increased frequency of gene rearrangements within the waxy locus facilitated the origination of many high-amylopectin corn lines carrying different SSR allelic variants. The purpose of this study was to evaluate the effectiveness of using waxy locus microsatellite sequences for identification and labeling of waxy maize genotypes. To this end, a complex of biochemical (calorimetry, bichromate method), molecular-genetic (SSR-PCR, capillary gel electrophoresis with fluorescent detection of fragments) and statistical (descriptive statistics, cluster analysis, χ2) analysis methods was used. Plant material used were 33 samples of corn kernels including mutant forms with a high content of amylose, amylopectin, short-chain starches, were kindly provided by VIR genetic collection (Russian Federation) and Maize Genetics Cooperation Stock Center (USA). The contents of starch, short-chain soluble carbohydrates, amylose, amylopectin in the grain of 33 maize samples were evaluated. Compositionally similar (to endosperm carbohydrates content) groups of samples were identified. They include 13 high-amylopectin samples carriers of waxy (wx) gene mutations and 20 samples with wild-type character (Wx). Molecular genetic screening of the collection included an analysis of the polymorphism of the microsatellite loci phi022, phi027, phi061 associated with the waxy gene sequence. Allelic composition of individual loci and their combinations were analyzed in relation to the accumulation of reserve carbohydrates in the kernel endosperm. Only the analysis of the phi022/phi027 combination or all three markers in the complex allows differentiating the wild Wx and mutant wx phenotypes of maize. It was shown that not the individual allelic polymorphisms of the phi022, phi027, phi061 loci are efficient for the markerassociated selection of high-amylopectin maize, but their unique combinations.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>кукуруза</kwd><kwd>запасные углеводы</kwd><kwd>крахмал</kwd><kwd>амилопектин</kwd><kwd>амилоза</kwd><kwd>ген waxy</kwd><kwd>микросателлитные маркеры</kwd></kwd-group><kwd-group xml:lang="en"><kwd>maize</kwd><kwd>reserve carbohydrates</kwd><kwd>starch</kwd><kwd>amylopectin</kwd><kwd>amylose</kwd><kwd>waxy gene</kwd><kwd>microsatellite markers</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">Alexander D.E., Creech R.G.
