Using sequencing and multiple alignment methods the SNP, deletions, insertions in the target genes was established in comparing with the reference B73 maize line, and the phylogenetic trees were prepared. The presence of a 4-nucleotide insertions (4NI) and 15 identical SNP in the <italic>Zm_Pla1</italic> gene of the ancestral Stock 6 and haploid-inducing ZMS-8 and ZMS-P maize lines and the absence of 4NI in the <italic>Zm_Pla1</italic> gene in parthenogenetic as well as control maize lines were established. Phylogenetic analysis of the <italic>Zm_Pla1</italic> gene confirmed the relationships between Stock 6 and haploid-inducing ZMS-P and ZMS-8 maize lines from Saratov. The presence of 5 SNPs in the <italic>Zm_Dmp7</italic> gene of the ZMS-8 line, 3 SNPs and one 3-nucleotide deletion in the <italic>Zm_Dmp7</italic> gene of the ZMS-P line, 3 SNPs and a 9-nucleotide deletion in the <italic>Zm_Dmp7</italic> gene of the KM line were observed. The SNP (at position 131 from the start codon) in the <italic>Zm_Dmp7</italic> gene is the reason for the increased haploid-inducing ability in CAU5, but not for ZMS-P maize line. Additionally, the 3-nucleotide deletion in the <italic>Zm_Dmp7</italic> gene in the ZMS-P maize line and a 9-nucleotide deletion in the KM maize line were observed.</p></abstract><trans-abstract xml:lang="ru"><p>В статье приведен анализ полиморфизма нуклеотидных последовательностей генов, контролирующих гиногенез (<italic>Zm_Pla1, Zm_CenH3, Zm_Dmp7</italic>) у гаплоиндуцирующих (ЗМС-8, ЗМС-П) и контрольных (КМ, ГПЛ-1) линий кукурузы саратовской селекции. С помощью секвенирования и последующего множественного выравнивания транскриптов целевых генов исследуемых в работе линий и референсной линии кукурузы B73 определено наличие однонуклеотидных замен (ОНЗ), делеций и вставок, построены филогенетические деревья по изучаемым генам. Установлено наличие 4-нуклеотидной вставки в гене <italic>Zm_Pla1, </italic>которая обусловливает гаплоиндуцирующую способность у предковой линии Stock 6 и гаплоиндуцирующих линий ЗМС-8 и ЗМС-П, а также 15 идентичных ОНЗ. Но элементы партеногенеза, демонстрируемые линиями АТ-1, АТ-3 и АТ-4, у которых отсутствуют вставки из четырех нуклеотидов в гене <italic>Zm_Pla1</italic>, имеют иную генетическую основу. Филогенетический анализ гена <italic>Zm_Pla1 </italic>подтвердил родство гаплоиндуцирующих линий Stock6, ЗМС-П и ЗМС-8. В гене <italic>Zm_Dmp7 </italic>зафиксировано наличие пяти ОНЗ у линии ЗМС-8 и трех ОНЗ у линий ЗМС-П и КМ. Одна из ОНЗ (в положении 131 от стартового кодона) в гене <italic>Zm_Dmp7 </italic>является причиной повышенной гаплоиндуцирующей способности линии CAU5, но не ЗМС-П. Помимо этого, в гене <italic>Zm_Dmp7 </italic>обнаружены 3-нуклеотидная делеция у линии ЗМС-П и 9-нуклеотидная делеция у линии КМ.</p></trans-abstract><kwd-group xml:lang="en"><kwd>haploid-induction</kwd><kwd>maize</kwd><kwd>mutations</kwd><kwd>gene polymorphism</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>гаплоиндукция</kwd><kwd>кукуруза</kwd><kwd>мутации</kwd><kwd>полиморфизм генов</kwd></kwd-group><funding-group><award-group><funding-source><institution-wrap><institution xml:lang="ru">Российский научный фонд (проект)</institution></institution-wrap><institution-wrap><institution xml:lang="en">Russian Science Foundation (project)</institution></institution-wrap></funding-source><award-id>23-26-00101</award-id></award-group></funding-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Coe E.H.
