К настоящему времени для локусов VRN-1 описан ряд аллелей и разработаны аллель­специфичные праймеры, позволяющие проводить быструю идентификацию аллельного состава у сортов и линий мягкой пшеницы. Установлено неодинаковое влияние различных аллелей локусов VRN-1 на продолжительность вегетационного периода, однако исследований, касающихся влияния комбинации различных аллелей на время колошения, недостаточно. Получение полных наборов всех возможных генотипов по разным аллелям доминантных генов VRN на одном генетическом фоне необходимо для более глубокого изучения генетических эффектов генов VRN на продолжительность вегетационного периода и отдельных фаз развития, а также на продуктивность. Поскольку большинство современных сортов России несет доминантные аллели двух генов VRN (Vrn-A1a и Vrn-B1a или Vrn-B1c), нами была поставлена задача – получить линии, сочетающие доминантные аллели Vrn-A1a с Vrn-B1a и Vrn-B1c на генетическом фоне озимого сорта Безостая 1 (Без1 Vrn-A1a/Vrn-B1a и Без1 Vrn-A1a/ Vrn-B1c). С использованием известных аллель­специфичных праймеров для локусов Vrn-A1 и Vrn-B1 в поколении F 2 были выделены гомозиготные растения. У полученных линий с комбинацией двух доминантных аллелей локусов VRN-1 достоверно уменьшалась продолжительность периода «кущение–первый узел», который представляет собой ключевой этап, определяющий продолжительность вегетационного периода и периода от всходов до колошения по сравнению с изогенными линиями по сорту Безостая 1 с доминантными аллелями Vrn-B1a и Vrn-B1c. По сравнению с изогенной линией с доминантным аллелем Vrn-A1a у полученных линий также произошло уменьшение продолжительности этих фаз развития, однако различия были недостоверны. Достоверных различий по продолжительности остальных фаз развития у линий с двумя доминантными аллелями локусов VRN-1 относительно изогенных линий по сорту Безостая 1 выявлено не было.</p></abstract><trans-abstract xml:lang="en"><p>VRN genes, determining wheat sensitivity to vernalization, are the main genetic system that defnes the duration of the entire growing period and the durations of the main organogenesis phases. To date, several alleles have been described for VRN-1 loci, and allele­specifc primers have been developed that allow rapid identifcation of allelic spectra in common wheat varieties and lines. The unequal inﬂuence of diﬀerent alleles of VRN-1 loci on the duration of the growing period has also been shown; however, there is little information on the eﬀect of the combination of diﬀerent alleles on heading time. In developing genotypes having diﬀerent alleles of dominant VRN genes on the base of the same genetic background, it is necessary to study the genetic eﬀects of VRN genes on the duration of the growing season and the individual developmental phases, as well as on productivity. Most varieties presently grown in Russia carry the dominant alleles of two VRN-1 genes: Vrn-A1a and Vrn-B1a or Vrn-B1c; thus, the task was to create lines combining the dominant alleles of Vrn-A1a with Vrn-B1a and Vrn-B1c against the genetic background of the winter variety Bezostaya 1 (Bez1 Vrn-A1a/Vrn-B1a and Bez1 Vrn-A1a/Vrn-B1c). Homozygous plants were isolated in the F2 generation by using known allele­specifc primers for the Vrn-A1 and Vrn-B1 loci. The durations of the tillering–frst node period, which is the key stage determining growing duration, and the period from shoots to heading were signifcantly reduced in lines with a combination of two dominant alleles of VRN-1 loci compared to isogenic lines of Bezostaya 1 with the dominant alleles Vrn-B1a and Vrn-B1c. The duration of these developmental phases also decreased in the obtained lines as compared to the isogenic line containing the dominant Vrn-A1a allele, but the diﬀerences were not signifcant. No substantial diﬀerences were found in the duration of other growing phases in lines with two dominant alleles of the VRN-1 loci as compared to isogenic lines of Bezostaya 1.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>линии мягкой пшеницы</kwd><kwd>продолжительность фаз развития</kwd><kwd>аллели локуса VRN-1</kwd><kwd>аллель-специфичные праймеры</kwd></kwd-group><kwd-group xml:lang="en"><kwd>common wheat lines</kwd><kwd>duration of growing phases</kwd><kwd>alleles of the VRN-1 loci</kwd><kwd>allele¬specifc primers</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">Cockram J., Jones H., Leigh F.J., O’Sullivan D., Powell W., Laurie D.A., Greenland A.J.
