[The alien genetic variability for amelioration of wheat grain quality characteristics].
The alien germplasm presented by different wild wheat relatives 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), T. palmovae (AADD, 2n = 28) was involved into interspecific crosses with T. aestivum to produce transfers of exotic Gli/Glu-alleles to cultivated bread wheat varieties. The array of novel exotic Gli/Glu-alleles was introduced into cultivated wheat genome. Considerable negative as well as positive influence of some exotic alleles on bread-making quality characters or endosperm texture was observed. The original interspecific material with improved quality characteristics was recommended to be applied for wheat breeding.
