Marker-based Methods for Locating and Transferring of Viral Resistance Genes in Potato: A Review

Molla G. Taye*, András P. Takács

Potato is a diverse and well-adapted food, feed, and industrially important non-cereal crop in the world. There are more than 40 viral diseases that have been recorded and have an inherent capacity of infecting potato universal. The yield reduction due to potato viruses can reach up to 80% with the possibility of total crop failure. Alleviating the potato virus diseases induced challenges involved various viral management options. However, breeding for viral-resistant potato varieties via efficient and accurate breeding techniques like marker-assisted selection (MAS) has made significant improvements in sustainable potato virus disease management. Therefore, this review gives some insight into what is known about the latest DNA-based mapping techniques and introgression approaches used in potato virus resistance breeding schemes in general. Eventually, this review briefly discusses and summarizes the properties of an ideal genetic marker, types of genetic markers, genetic linkage mapping, genome association mapping, and QTL detection, RNA-seq, whole-genome re-sequencing, pyramiding, marker-assisted selection, and CRISPR/Cas9 genome editing technology.
