Overview on domestication, breeding, genetic gain and improvement of tuber quality traits of potato using fast forwarding technique (GWAS): A review

Tuber quality is the subject of great interest among processing industry and consumers worldwide. Being a polygenic trait, its enhancement requires systematic understanding their genetic complexity. Molecular genetics offered valuable solutions to challenging endeavours slow gains in conventional potato breeding. With advent linkage maps, molecular markers availability next-generation sequencing (NGS) platforms, plant breeding programmes worldwide have achieved faster gain due marker-assisted selection (MAS). Linkage mapping detects QTLs biparental population; alternatively, genomic phenotypic differences can be identified by extensive genotyping phenotyping germplasm panel depicting natural biological diversity reveal QTLs, other words, marker-trait associations. Due advancements fields genome bioinformatics, researchers preferred use genome-wide association (GWAS) method for detecting higher resolution. In potato, GWAS causative allele(s)/loci provides reliable platform development diagnostic SNP employing Infinium SolCAP array. Later, KASP validation developed used as order bred improved cultivars. The current review focuses on recently approaches analyses (linkage or mapping) regarding tuber traits, comprehensive knowledge about breeding, gain, basic statistical concepts subsequently highlights discoveries using markers.
