Согласно опубликованным сведениям при скрещивании F. х ananassa Duch. (8x) х P anserina L. (4х) возникают гаплоиды, 8х-потомки партеногенетического происхождения и анеуплоиды. Жизнеспособных гибридов не было получено. Нами проводились многолетние исследования по гибридизации F. х ananassa х P anserina с целью получения 8х-агамоспермного потомства и изучения в этом потомстве характера генетической изменчивости. В одном из экспериментов при использовании в скрещиваниях пыльцы P. anserina, наряду с матроморфными потомками с 2n = 56 был получен один сеянец (№ 89-3), который являлся полностью стерильным, фенотипически незначительно отличался от F. х ananassa, т. е. соответствовал Fragaria-типу. Подсчет чисел хромосом в клетках корневой меристемы этого сеянца показал 2n = 6x = 42 промежуточное число хромосом между скрещиваемыми родительскими формами. Отсутствие каких-либо морфологических признаков опылителя (P. anserina) инициировало нас на проведение молекулярно-генетического анализа, чтобы окончательно прояснить его происхождение. Проведен RFLP-анализ гена ингибитора полигалактуроназы, а также ITS внутреннего транскрибируемого спейсера, входящего в состав кластера генов, кодирующих рРНК, который показал, что сеянец № 89-3 и партеногенетические потомки по молекулярным маркерам соответствовали материнской форме F. х ananassa, т. е. сеянец № 89-3 является анеуплоидом. В связи с этим наиболее вероятным сценарием формирования у исследуемого образца № 89-3 хромосомного набора 2n = 42 следует считать элиминацию 14 хромосом P. anserina и 14 хромосом F. х ananassa во время первых делений гибридного зародыша (2n = 70), который возник в результате оплодотворения нередуцированной яйцеклетки F. х ananassa (n = 56) редуцированным спермием P. anserina (n = 14). В итоге это событие исключило геномный материал лапчатки в соматических клетках сеянца. Появление анеуплоидов и партеногенетических 8х-потомков при скрещиваниях F. х ananassa х P anserina, позволяет изучать дополнительные механизмы формирования изменчивости в роде Fragaria. Репродуктивная изоляция анеуплоида, ввиду его полной стерильности, позволяет использовать его лишь как почвопокровное растение. Кроме того, его фитомасса может быть пригодна для производства ферментированных чайных напитков</p></abstract><trans-abstract xml:lang="en"><p>Taxonomic relationship between Fragaria L. and Potentilla L. representatives is actively discussed today in the context of phylogenetic analysis by molecular markers and hybridization results. According to the data published, crosses between F. х ananassa Duch. (8x) х P anserina L. (4x) produce haploids, parthenogenetic seedlings (8x) and aneuploids. No viable progenies have been obtained. Our long-standing research in F. х ananassa х P anserina hybridization was targeted at obtaining 8x agamospermic progenies and studying their genetic variability. In one of the experiments, when P. anserina pollen was used in crosses, along with 2n = 56 matromorphous seedlings, an absolutely sterile seedling No. 89-3 was produced, which insignificantly differed from F. х ananassa by its phenotype, thus matching the Fragaria type. Chromosome number in root apical meristem cells appeared to be 2n = 6x = 42, being intermediate between the crossed parental forms. The absence of any morphological traits of the pollen parent (P. anserine) showed the need to make molecular genetic analysis in order to prove its hybrid origin. Methods. To trace its origin, the techniques of Polygalacturonase Inhibitor Proteins (PGIPs) PCR and Amplified Fragment Length Polymorphism (AFLP) PCR analysis of internal transcribed spacer (ITS) were applied to F. х ananassa х P anserina seedlings. The study showed that seedling No. 89-3 and the parthenogenetic progenies are identical and correspond to the mother form (F. х ananassa). Hence, eliminating 14 chromosomes of F. х ananassa and 14 chromosomes of P. anserina during the first divisions of a zygote (2n = 70) should be considered as the most likely scenario for the 2n = 42 chromosome number development in the studied No. 89-3, so the genetic material of P. anserina was absent in the embryo’s somatic cells. Development of aneuploids and parthenogenetic seedlings (8x) in the crosses of F. х ananassa х P anserina makes it possible to study additional mechanisms of variability appearing in the Fragaria genus. Reproductive isolation of an aneuploid, due to its complete sterility, limits its use solely to a cover plant’s role. In addition, its herbage biomass may be used for making fermented tea.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>Fragaria х ananassa</kwd><kwd>Potentilla anserina</kwd><kwd>межродовая гибридизация</kwd><kwd>ПЦР</kwd><kwd>RFLP</kwd><kwd>межродовые гибриды</kwd><kwd>анеуплоидия</kwd><kwd>элиминация хромосом</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Fragaria х ananassa</kwd><kwd>Potentilla anserina</kwd><kwd>intergeneric crosses</kwd><kwd>PCR</kwd><kwd>RFLP</kwd><kwd>intergeneric hybrids</kwd><kwd>aneuploidy</kwd><kwd>chromosome elimination</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">Alvarez I, Wendel JF (2003) Ribosomal ITS sequences and plant phylogenetic inference.
