Abstract

Foreign genetic variability, which is represented by different wild-growing relatives of wheat such as Ae. umbellulata (UU, 2n = 14), Ae. cylindrica (CCDD, 2n = 28), Ae. tauschii (DD, 2n = 14), Ae. ventricosa (DDUnUn, 2n = 28), Ae. variabilis (UUSS, 2n = 28), and T. palmovae (AADD, 2n = 28) is used in interspecies crossings with the wheat cultivar T. aestivum for the purpose of transferring exotic Gli/Glu alleles into the genome of the crop. As a result, a series of new exotic Gli/Glu alleles is introgressed into the genome of wheat cultivar. An essential negative as well as positive influence of the wild exotic alleles on the baking quality indicators of the flour and the consistency of the wheat endosperm is discovered in the course of the study. The new genetic material with the improved grain quality indicators is recommended for use in wheat selection.
