Interpretive Summary:

Technical Abstract: Wild diploid potato has historically been an important source of genetic variation for variety development in S. tuberosum. In previous research, the diploid line S. chacoense 524-8 had consistently displayed resistance to common scab, a widespread disease caused by the soil-borne bacterial pathogen Streptomyces scabies. Line 524-8 had also demonstrated resistance to cold-induced sweetening, which is an important trait for the development of varieties with light fry color after long-term cold storage. The objective of this research was to localize the genetic basis for these resistance traits by mapping quantitative trait loci in a segregating diploid population.
