Genotyping-by-sequencing (GBS) is a useful technique for discovering high-quality SNPs and identifying hybrid individuals between different species. GBS can also be applied to finding backcrosses and has unlimited potential for use with restriction enzymes and species without reference genomes.
Genotyping-by-sequencing (GBS) is an extremely useful, modern and relatively inexpensive approach to discovering high-quality single-nucleotide polymorphisms (SNPs), which seem to be the most promising markers for identifying hybrid individuals between different species, especially those that can create backcrosses. In addition, GBS could become an invaluable tool in finding backcrosses, even several generations back. Its potential for the use of restriction enzymes and species is almost unlimited. It can also be successfully applied to species for which a reference genome is not established. In this paper, we describe the GBS technique, its main advantages and disadvantages, and the research carried out using this method concerning interspecies hybridisation and the identification of fertile hybrids. We also present future approaches that could be of interest in the context of the GBS method.
