[Detection of the introgression of genome elements of the Aegilops cylindrica host. into the Triticum aestivum L. genome by ISSR and SSR analysis].
To reveal sites of the donor genome in wheat crossed with Aegilops cylindrica, which acquired conferred resistance to fungal diseases, a comparative analysis of introgressive and parental forms was conducted. Two systems of PCR analysis, ISSR and SSR-PCR, were employed. Upon use of 7 ISSR primers in genotypes of 30 individual plants BC1 F9 belonging to lines 5/55-91 and 5/20-91, 19 ISSR loci were revealed and assigned to introgressive fragments of Aegilops cylindrica genome in Triticum aestivum. The 40 pairs of SSR primers allowed the detection of seven introgressive alleles; three of these alleles were located on common wheat chromosomes in the B genome, while four alleles, in the D genome. Based on data of microsatellite analysis, it was assumed that the telomeric region of the long arm of common wheat chromosome 6A also changed. ISSR and SSR methods were shown to be effective for detecting variability caused by introgression of foreign genetic material into the genome of common wheat.
