The results in obtaining pentaploid hybrids by crossing bread wheat with immune durum wheat introgressive lines derived of remote crossings are presented. It is shown that crossability of the species is high and reaches 71.5%. The variability of the characteristic is determined by a genotype and environmental conditions. Contribution of modificative variability is predominant. Fertility of F1 plants is similar to the result of backcrossing and discovered the same level in different growing conditions (about 50%). The viability of seeds in F1BC1 is 1.5 times lower compared to F2 progeny. The conclusion about the possibility of the involvement of Triticum timopheevii Zhuk. and T. boeoticum Boiss. genes in wheat breeding through the use of stable tetra-derivatives is made. Compatibility of immune durum forms with samples of bread wheat, as well as the viability and fertility of the first generations showed no fundamental limitations for introgression of resistance to  pathogens to hexaploid wheat.Keywords: bread wheat, introgressive lines, interspecific hybridization, pentaploid hybrids, compatibility, fertility, backcrossing, viability.
