Variability of the height of plants of hybrid forms of spring common wheat (Triticum aestivum L.) under different ecological and geographical conditions. N. A. Bome, D. Trautz
Abstract: The results of two-year research (2013–2014) of the variability of plant height in spring common wheat hybrid forms (F4, F5) in three geographical localities, including Russia (Tyumen region) and Germany (Baden-Württemberg and Lower Saxony), which differ considerably in soil …
Approaches to the development of durum wheat cultivars (Triticum durum Desf.) with wide variability of the growing season. P. N. Malchikov, M. G. Myasnikova
Abstract: Differentiation in the duration of growing period is an inherent and, in many respects, decisive factor of task-oriented formation of the cultivar pool in the region. The cause is that one cannot develop a universal cultivar that would be equally effective in …
Change of salt tolerance in common wheat after introgression of genetic material from Aegilops speltoides and Triticum timopheevii. R. S. Yudina, I. N. Leonova, E. A. Salina, E. K. Khlestkina
Abstract: To improve biotic and abiotic stress tolerance in common wheat (Triticum aestivum L.), novel genotypes with genomic fragments introgressed from other cereal species are extensively developed. One of the most important abiotic environmental factors that impede the expansion of wheat cultivation …
Study of resistance to leaf and stem rusts in Triticum aestivum–Aegilops speltoides lines. S. N. Sibikeev, S. A. Voronina, E. D. Badaeva, A. E. Druzhin
Abstract: 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 …
Prospects of the use of wild relatives for pea (Pisum sativum L.) breeding. O. E. Kosterin
Abstract: The current global climate change results in shift and shrinkage of ranges of crop cultivation. The potential of crop wild relatives as an important source of genetic diversity for breeding is underestimated. Wild relatives of pea include the species …
On the 160th anniversary of Ivan V. Michurin’s birth. N. P. Goncharov, N. I. Savel’ev
Abstract: October 2015 marks the 160th anniversary of the birth of Ivan V. Michurin. As a scientist and plant breeder, he made a significant improvement of many varieties of fruit, berry, and flowers. He developed methods of plant breeding, promoted gardening to the north …
Marker-assisted identification of maize genotypes with improved protein quality. O. A. Orlovskaya, S. V. Kubrak, S. I. Vakula, L. V. Khotyleva, A. V. Kilchevsky
Abstract: Currently, more than 70 % of maize is used for food and fodder; therefore, grain quality improvement can increase its nutritive and energy value. Deficiency of two essential amino acids (lysine and tryptophan) significantly reduces the nutritional quality of maize proteins. However, in comparison …
Formation of gene associations that code for general homeostasis and performance components of durum wheat (Triticum durum Desf.). P. N. Malchikov, M. G. Myasnikova
Abstract: Since 1912, durum wheat breeding in the Middle Volga region has passed several stages. Acceleration of the breeding process was observed during the period of joining gene pools from Bezenchuk (the Middle Volga region), Kharkov (Ukraine) and Saratov (the Lower Volga region), when the …
Identification of Sr genes in new common wheat sources of resistance to stem rust race Ug99 using molecular markers. O. A. Baranova, I. F. Lapochkina, A. V. Anisimova, N. R. Gajnullin, I. V. Iordanskaya, I. Yu. Makarova
Abstract: The need for new donors of resistance to aggressive race Ug99 of Puccinia graminis Pers. f. sp. tritici Eriks. et Henn has arisen because the pest approaches the territory of Russian Federation. Identification of seventeen known Sr genes was performed with use of …
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. S. N. Sibikeev, A. E. Druzhin
Abstract: 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 plants, performance indices, yield, and …
