The subject of the study are the features and patterns of transfer of alien genes from wild relatives to the genome of common wheat. The purpose of the work: the transfer to the genome of common wheat from its wild relatives of genes that improve the resistance of wheat to stress factors of biotic and abiotic nature. Research methods: visual, biochemical, cytological, molecular genetic, statistical. The main results of the work. The main result is the development of a new set of introgressone lines Triticum aestuivum / Aegilops mutica. Among them were lines resistant to powdery mildew and lines with increased winter hardiness. The lines are involved in a number of molecular genetic studies on the problem of transmission of alien genetic material from introgression sources to the common wheat genome. In an attempt to highlight the genetic basis of increased winter hardiness of Aurotica and some introgression lines, genotyping of line plants was performed on microsatellite loci specific to chromosomes of the 5th homeological group, known as that associated with wheat frost resistance. The best winter hardiness was distinguished by lines with alleles of microsatellite loci inherent in the genome T of the species Ae. mutica. Amphidiploid Aurotica and Aurora variety differ in the architectonics of the root system. Introgression lines, which approach Aurotica in winter hardiness, are characterized by the architectonics of the root system inherent in Aurotic, and not Aurora. On introgression lines, derivatives of genomic-substituted amphidiploids of Aurosis, Aurodes, and Aurolate, it has been shown that a trait of alien origin, the dark color of mature glume, is controlled by orthological Rg genes included in their genomes as part of the translocations or recombination products of chromosomes 1Ssh, 1S, 1U, respectively, with wheat chromosomes.
