Abstract

Aim. To investigate advanced introgression lines of bread winter wheat for resistance to common diseases, to determine their breeding value, to identify donor lines with the maximum manifestation of valuable alien traits, adapted to growing conditions in southern Ukraine. Methods. Field, laboratory, comparison, generalization, mathematical statistics. Results. In the study of advanced introgression wheat lines, it was found that the trend of the distribution of lines for reaction to the diseases may indicate the genetic determination of their resistance, and the genetic basis of individual lines was favorable for combining the wheat-rye translocation 1BL.1RS with other both alien and wheat resistance genes. The lines carrying resistance to several diseases, high yield, adaptability and baking grain quality were identified. Conclusions. As a result of numerous crosses of sources of alien genetic material of various origins with modern bread winter wheat cultivars, a few breeding lines were obtained that were carriers of the traits of resistance to diseases, high parameters of 1000-kernel weight, protein content, devoid of the negative traits inherent in wild species. This indicates the complexity, but the prospects of introgression breeding of bread winter wheat.
