Abstract
The effects of the combinations 7DS-7DL-7Ae#1L (Lr19 gene) and 1BL-1RS (Lr26 gene) translocations, substitution of 6D(6Agi) (Lr6Agi gene) and 1BL-1RS translocation, as well as translocations of 7DS-7DL-7Ae#1L, 1BL-1RS and Lr39 gene on the bread making quality were evaluated in spring bread wheat introgressive lines. It was found that the genotype of recipient, the 1BL-1RS translocation donor, and the vegetation conditions have a great influence on the parameters quality of flour and bread. The role of selection within a single crosses combination for production of lines with good quality indicators is revealed. The high compensatory ability of the cultivar L505 and the synthetic hexaploid line with the pedigree Croc/Ae.squarosa(205)//Weaver (1BL-1RS translocation + Lr39 gene) for reducing the negative effect of the 1BL-1RS translocation on bread making quality was noted.
