Для вовлечения в селекцию генофонда этих видов предлагается использовать оригинальные SvSv-линии (F2 дигаплоиды S. tuberosum×S. verrucosum), у которых St -аллели культурного картофеля замещены на Sv от самосовместимого диплоидного вида S. verrucosum, не образующего пестичных S-РНКаз. Предполагалось, что благодаря наличию в гомозиготном состоянии S-генов, привнесенных от S. verrucosum, SvSv-линии имеют те же возможности для устранения презиготной несовместимости при межвидовой гибридизации, что и этот дикий вид, однако их использование позволит устранить нежелательные эффекты, связанные с его применением (мужская стерильность гибридов, пониженное клубнеобразование). Целью исследования была оценка эффективности использования SvSv-линий (по сравнению с S. verrucosum) в качестве посредника для вовлечения в селекцию 1 EBN видов картофеля S. bulbocastanum, S. pinnatisectum и S. polyadenium. Установлено, что SvSv-линии превосходят S. verrucosum по эффективности гибридизации с 1 EBN видами благодаря обильному и продолжительному цветению в более поздние, по сравнению с S. verrucosum, сроки, когда наступает цветение видов-опылителей. Среди гибридов между SvSv-линиями и 1 EBN дикими видами было достоверно меньше стерильных и низкофертильных генотипов и больше генотипов со средней и высокой функциональной фертильностью пыльцы. Они обладали более высокой способностью к клубнеобразованию, благодаря чему, в отличие от гибридов на основе S. verrucosum, были пригодны для многолетней селекционной оценки в полевых условиях. Полученные межвидовые гибриды удалось скрестить в качестве материнских форм с дигаплоидами S. tuberosum.</p></abstract><trans-abstract xml:lang="en"><p>There is a set of wild potato species valuable for breeding, in particular 1 EBN diploid species from Mexico, which is practically not crossable to cultivated potatoes, including Solanum tuberosum dihaploids (2х, 2 EBN), because of strict pre- and postzygotic interspecific reproductive barriers. It is proposed to involve that species germplasm into breeding by using the original SvSv-lines (F2 S. tuberosum dihaploids×S. verrucosum), in which St -alleles have been substituted for Sv from the self-compatible diploid species S. verrucosum not producing stylar S-RNase. It was anticipated that SvSv-lines have the same ability for elimination of prezygotic incompatibility in interspecific hybridization as S. verrucosum due to S-genes of that species in homozygous state. However, their use would help avoid undesirable effects associated with S. verrucosum application (male sterility and reduced tuber formation in hybrids). The aim of the research was estimation of the efficiency of using SvSv-lines, in comparison with S. verrucosum, as a bridge for involvement of the 1 EBN potato species S. bulbocastanum, S. pinnatisectum and S. polyadenium into breeding. It was revealed that SvSv-lines excels S. verrucosum in hybridization efficacy due to abundant and prolonged flowering in later term than S. verrucosum, when flowering of pollinator species occurs. There were significantly less sterile or low fertility genotypes among the hybrids between SvSv-lines and 1 EBN wild species. They had higher ability for tuber formation, and so they were suitable for long term field trials, contrast to hybrids with S. verrucosum. The interspecific hybrids produced were crossed as female parents to S. tuberosum dihaploids.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>картофель</kwd><kwd>отдаленная гибридизация</kwd><kwd>презиготная несовместимость</kwd><kwd>балансовое число эндосперма – EBN</kwd><kwd>S. verrucosum</kwd><kwd>SvSv-линии</kwd></kwd-group><kwd-group xml:lang="en"><kwd>potato</kwd><kwd>hybridization between distantly related species</kwd><kwd>prezygotic incompatibility</kwd><kwd>endosperm balance number – EBN</kwd><kwd>S. verrucosum</kwd><kwd>SvSv-lines</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">Abdalla M.M., Hermsen J.G.Th.
