Interpretive Summary: Potato common scab results in marketable yield losses, as diseased tubers must be discarded. We are using a wild relative of potato as a source of resistance to this disease. This paper describes three clones with high levels of resistance. We are releasing them for use by breeders for cultivar development.

Technical Abstract: Common scab caused by the soil-borne bacterium Streptomyces scabies is a serious disease for the potato industry. We have identified a strong source of resistance in the diploid wild relative Solanum chacoense. This resistance has been introgressed into tetraploid cultivated potato via unilateral sexual polyploidization. This paper describes three hybrid clones for use by potato breeding programs to enhance resistance to common scab. The clones are male and female fertile, and are adapted to temperate zone production environments.
