Abstract: 
In the course of a research aimed at the genetic improvement of wheat through intergeneric hybridization, 24 inbred breeding lines obtained by the hybridization
of Triticum aestivum cv. ‘Chinese Spring’ (CS) or T. turgidum ssp. durum cv. ‘Modoc’ followed by backcross to CS have been characterized cytogenetically. Some lines were found to have the same karyotype as CS. In other lines, karyological events such as chromosome addictions, chromosome substitutions, recombinations between parental genomes or between the homoeologous genomes of wheat were observed. These findings, which were in part unexpected and even surprising, show that a careful cytogenetic characterization of
wheat hybrids is necessary to understand factors and mechanisms that play a role in determining the structure of their karyotype, and then to choose strategies for the genetic improvement of wheat by interspecific and/or intergeneric hybridization.
