Application of DNA Barcode for Cultivar Identification in Tuber Crops

Abstract

For precise species identification, DNA barcoding depends on sequence variation within a condensed and defined section of the genome known as a “barcode.” This strategy is based on the analysis of variation within a typical DNA barcode area, which is helpful in determining taxonomic relationships. The number of studies involving identification, taxonomic decisions and the discovery of cryptic species has grown rapidly. Recently, tuber crops have gained more popularity as when compared to other staples. They come in a variety of species and variants that have either developed naturally or as a result of human intervention. In order to properly characterise them and research their variety, which may ultimately result in the genetic development of these crops, it is imperative to utilise DNA barcodes to identify them.
