Abstract:

Potato is the world's number one non-grain commodity and ranks at fourth position after maize, rice and wheat. As a species, potato is very docile to cell culture, it also contains an extended history of applications in the field of biotechnology for the improvement of crops. The genomic insurgency from the recent past has significantly enhanced the overall knowhow of the genetic structure of all the crops. Crop genome sequences has totally reformed our view and understanding for genome association and genome development. Increased knowledge in markers along with the advanced phenotyping, genotyping by sequencing, genomewide association studies added a new way for determining marker-trait associations that can withstand genome based breeding programs. Accessibility of sequencing of genomic data has permitted editing of genome (localized mutagenesis), for obtaining sequences of gene that is anticipated by the breeders. To develop some genetic maps, markers application and genomics in the field of potato breeding these genetic characteristics have also assigned the tasks to the breeders. Many strategies are formulated to describe the potato loci, (contender) genes and alleles, and association of genotype with the phenotype are also stated. This review demonstrates how next generation phenotyping, genome-wide association studies and genome editing tools can be used to modify tools to genomics for the need of potato breeders to transform potato improvement.
