“…Recently, Byrne et al (2020) identified a major QTL on chromosome 10 for fry color and predicted fry color with moderate accuracy using genome-wide markers. Frederick and Bethke (2019) identified nine QTLs for stem-end chip defects, seven of which overlapped with QTLs for chip color traits. Other efforts to practically apply the SNP panel have focused on genome-wide association studies (GWAS) to identify markertrait associations.…”

Potato is a major food crop in the United States and around the world. Most potatoes grown in the United States are destined for processing. Genomic selection can speed up breeding progress for important traits, including those with complex inheritance by guiding the identification of the best parents and guiding selection to advance clones in the breeding program. However, the application of genomic selection in polyploid species has been challenging. In this study, we obtained breeding values of 384 chipping clones evaluated in Texas between 2017 and 2020. The mean reliability of the genomic‐estimated breeding values obtained were 0.77, 0.41, 0.61, 0.71, and 0.24 for chip color, chip quality, specific gravity, vine maturity, and total yield, respectively. Potato clones with good chip quality, high yield, high specific gravity, and light‐color chips were identified using a multi‐trait selection index based on weighted standardized genomic‐estimated breeding values. Genome‐wide association studies identified quantitative trait loci on chromosome 5 for vine maturity and chromosomes 1, 3, and 7 for chip color. This research has laid the groundwork for implementing genomic selection in tetraploid potato breeding and understanding the genetic basis of chip processing traits in potatoes.
