This paper reviews the results of studies of interspecies hybridization, polyploidization, as well as phylogenetic relationships of Solanum species and members of closely related taxa by such molecular cytogenetic techniques as genomic (GISH) and fluorescent (FISH) DNA-DNA in situ hybridization. The latter was used to determine the genomic composition and origin of wild species of the Petota section, while the FISH technique was used for detecting intergenomic collinearity. The combination of these two types of research made possible a comparative analysis of karyotypes and genomes, thus allowing a better understanding of the meiotic interchromosomal interactions in hybrids. This review primarily focuses on the studies of wild allopolyploid potato species and artificially created intergeneric and interspecific hybrids of the genus Solanum and their offspring.
