Synthetic hexaploids are bridges for transferring new genes that determine resistance to stress factors from wild-type species to bread wheat. In the present work, the method of developing the spring bread wheat variety Pamyati Maystrenko and the results of its study are described. This variety was obtained using one of the immune lines produced earlier via(More)
The effectiveness of molecular markers for the identification of leaf rust resistance genes Lr28, Lr35 and Lr47 transferred to common wheat from Ae. speltoides was assessed using samples of Triticum spp. and Aegilops spp. The markers Sr39F2/R3, BCD260F1/35R2 of the gene Lr35 and PS10 of the Lr47 gene were characterized by high efficiency and were revealed(More)
Little is known about the relationship between compact spike loci in hexaploid wheat species. We studied two new compact spike mutants of common wheat Triticum aestivum L. (2n = 6x = 42, genome formula BBAADD). The new compact spike genes, C 739 of MCK 739 and Cp of near-isogenic line Mironovskaya 808 (Vrn1), were mapped using aneuploid stocks and(More)
Using C-banding and FISH methods, the karyotype of MC1611 induced mutant of bread wheat, which develop additional spikelets at a rachis node (trait “supernumerary spikelets”) was characterized. It was determined that the mutant phenotype is not associated with aneuploidy and major chromosomal rearrangements. The results of genetic analysis showed that(More)
