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 …
Development of new SSR markers for homoeologous WFZP loci based on the study of structure and location of microsatellites in gene-rich regions of chromosomes 2AS , 2BS, 2DS. O. B. Dobrovolskaya, C. Pont, Yu. L. Orlov, J. Salse
Abstract: Microsatellites, or simple sequence repeats (SSRs), are ubiquitous in genomes of eukaryotes, including plant genomes. The structure and location of SSR loci determine their potential as molecular genetic markers and may have impact on the potential function of microsatellites in important biological processes. Identification and …
The modulating effect of coat color mutations on the generation and neutralization of reactive oxygen species in the Аmerican mink (Neovison vison) as a model. S. N. Sergina, V. A. Ilyukha, I. V. Baishnikova, T. N. Ilyina
Abstract: The influence of gene mutations encoding coat color on parameters of reactive oxygen species (RO S) generation and neutralization in six organs of the mink (Neovison vison) was evaluated. The study was conducted with standard dark brown (+/+), monorecessive royal pastel (b/b) and silver-blue (р/р), …
Reproductive performance and increased fecundity in the chinchilla (Chinchilla laniger Molina). M. V. Novikov, N. N. Shumilina
Abstract: Our overview of the global practice of breeding chinchillas systematizes information about performance and reproduction conditions that determine the profitability of fur farms. Captive chinchillas are polygamous and polyestrous. Seasonal differences in the organosomatic indexes, the number of spermatozoids in males, and the duration of the sexual …
The Canis tangle: a systematics overview and taxonomic recommendations. V. Dinets
Abstract: Despite high research interest, the systematics and taxonomy of mammalian genus Canis are among the most convoluted and controversial: species boundaries are blurred and incongruent with any existing species concept, while genetic differences between species are low. I provide an overview of existing controversies, the …
Application of reproductive technologies to the improvement of dairy cattle genomic selection. N. S. Yudin, K. I. Lukyanov, M. I. Voevoda, N. A. Kolchanov
Abstract: Genomic selection is a direction of breeding in which the value of an animal is predicted from DNA markers evenly covering the entire genome. This review summarizes information on modern trends in the genomic selection of dairy cattle and on application of reproductive technologies …
