Phenotypic selection which is based on appearance and performance has several limitations such as difficulty of separating environmental and genetic contribution; difficulty of distinguishing homozygous and heterozygous effects; need for large space and labor input and the long time required. Genome-wide selection is a DNA based selection method in which several loci are selected using genomic estimated breeding values (GEBVs) based on genome-wide marker profiling. The phenotypes are predicted based on genotypes alone. This presentation looks at the current status of sweetpotato genetic and genomic resources and how genomic assisted breeding approaches can be utilized in sweetpotato improvement.
