Historical data provide new insights into inheritance of traits important for diploid potato breeding.

ABSTRACT:

Key message

Using a diploid potato diversity panel of 246 breeding lines, a genotyping-by-sequencing and a GWAS approach, we mapped QTL for ten traits important to potato breeders, including two previously unmapped traits: boiled tuber taste and pollen fertility. Potato breeding at the diploid level has a long history and has gained new impetus recently, when F1 hybrid breeding was made possible with the discovery of a dominant gene for self-compatibility. Our study deploys a unique diploid diversity panel with a broadened cultivated potato gene pool obtained as a result of introgressing valuable traits from wild potato relatives into the Solanum tuberosum background. Using historical phenotyping data collected between 1979 and 2017 for 246 diploid potato clones and high-density ge
