    Prebreeding research of near-isogenic lines of spring bread wheat with a combination of translocations from Agropyron elongatum (Host.) Р.В. and Aegilops ventricosa Tausch. af S. N. Sibikeev, A. E. Druzhin

    Udgivet 2015-07-01

    To protect bread wheat from pathogens and, in particular, rust diseases, introgressive resistance genes located in alien translocations are commonly used. However, their application in practical breeding demands prebreeding studies. They reveal effects of translocations on the adaptive properties of...

    The use of the species <i>Triticum petropavlovskyi</i> Udacz. et Migusch. to expand the genetic diversity of spring bread wheat af A. E. Druzhin, S. N. Sibikeev, L. V. Andreeva

    Udgivet 2024-10-01

    Background. The species Triticum petropavlovskyi Udacz. et Migusch. has a number of positive traits, but has rarely been used in breeding programs to improve bread wheat cultivars. The introgression of genetic material from this species into the Triticum aestivum L. gene pool will not only expand th...

    A prebreeding study of introgression spring bread wheat lines carrying combinations of stem rust resistance genes, Sr22+Sr25 and Sr35+Sr25 af S. N. Sibikeev, O. A. Baranova, A. E. Druzhin

    Udgivet 2021-12-01

    The Sr22, Sr35, and Sr25 genes attract the attention of bread wheat breeders with their effectiveness against Puccinia graminis f. sp. tritici race Ug99 and its biotypes. The effectiveness and impact of Sr22+Sr25 and Sr35+Sr25 gene combinations on agronomic traits have not yet been studied. In the p...

    Study of resistance to leaf and stem rusts in Triticum aestivum–Aegilops speltoides lines af S. N. Sibikeev, S. A. Voronina, E. D. Badaeva, A. E. Druzhin

    Udgivet 2015-07-01

    Presently, the use of bread wheat introgression lines resistant to pathogens in practical breeding is hampered by the lack of their cytogenetic characteristics, data on the genetic control of disease resistance, and influence of alien genetic material on grain productivity and quality. For the solut...

    The effect of the 7DL-7Ae#1L·7Ae#1S translocation on the productivity and quality of spring bread wheat grain af S. N. Sibikeev, E. I. Gultyaeva, A. E. Druzhin, L. V. Andreeva

    Udgivet 2022-10-01

    The 7DL-7Ae#1L·7Ae#1S translocation with the Lr29 gene attracts the attention of bread wheat breeders by its effectiveness against Puccinia triticina. However, its impact on useful agronomic traits has been little studied. In this report, the prebreeding value of 7DL-7Ae#1L·7Ae#1S was studied in ana...

    Prebreeding studies of leaf rust resistant <i>Triticum aestivum/T. timopheevii</i> line L624 af S. N. Sibikeev, I. G. Adonina, A. E. Druzhin, O. A. Baranova

    Udgivet 2023-11-01

    Triticum timopheevii Zhuk. attracts the attention of bread wheat breeders with its high immunity to the leaf rust pathogen. However, introgressions from this species in Triticum aestivum L. are little used in practical breeding. In the presented study, the agronomic value of T. aestivum/T. timopheev...

    <i>Triticum durum</i> Desf. is a valuable source for spring bread wheat genetic diversity enhancement af A. E. Druzhin, S. N. Sibikeev, E. I. Gultyaeva, L. B. Andreeva

    Udgivet 2023-10-01

    Background. Enhancement of the Triticum aestivum L. genetic diversity by means of alien chromatin, including that from Triticum durum Desf., is an important element in the breeding of bread wheat cultivars that meet modern requirements.Materials and methods. The study included the L153, L154 and L15...

    PREHARVEST SPROUTING RESISTANCE IN SPRING BREAD WHEAT CARRYING CHROMOSOME 6Agi(6D) FROM Agropyron intermedium af V. A. Krupnov, G. Yu. Antonov, A. E. Druzhin, O. V. Krupnova

    Udgivet 2014-12-01

    A significant adverse effect of chromosome 6Agi(6D)-from Agropyron intermedium on preharvest sprouting resistance was foundin inbredlines (F7–F10 or senior) andnear-isogeniclines of red-grain andwhite-grain common spring wheat. The red-grain recombinant inbredlines, carrying this substitution chromo...
