A study of the influence of the T2DL.2DS-2SS translocation and the 5S(5D) substitution from Aegilops speltoides on breeding-valuable traits of common wheat.

The use of the gene pool of wild relatives for expanding the genetic diversity of common wheat is an important task of breeding programs. However, the practical application of common wheat lines with alien genetic material is constrained by the lack of information on chromosomal rearrangements and the negative impact of the transferred material on agronomically important traits. This research is aimed at studying 14 introgression lines with the T2DL.

Using the synthetic form RS5 to obtain new introgressive lines of common wheat.

The use of the gene pool of wild relatives, which have a signif icant reserve of genetic diversity, is of immediate interest for breeding common wheat. The creation and use of synthetic forms as "bridges" is an effective method of transferring valuable genetic material from wild relatives to cultivated wheat. For this purpose, genome addition, genome substitution and recombinant "secondary" synthetic forms have been created in the P.
