Abstract

Interspecific hybrids with different number of chromosomes in meiosis were obtained during the analysis of 4 interspecific hybrids combination BC1 (Nadezhda x T. timophevii) Triticum (T.) Nadezhda; (К-2780 х T. timophevii) х К-2780; (T.dicoccum х Kokbidai) х Kokbidai; (К-2780 х T. timophevii) х К-2780, derived from crosses of soft wheat varieties with wild wheat species of Т. timopheevii, T.dicoccum and hexaploid T. kiharae. From one to six reconstructions were revealed in the karyotypes of interspecific hybrids. In accordance with the mechanisms of emergence they can be divided into pycnosis, translocations asynapsis, di-and tricentric bridges.
