The major threat to potato production is the Irish famine pathogen Phytophthora infestans which causes the devastating late blight disease. Potato breeding makes use of germplasm from wild relatives wild germplasm to introduce resistances into cultivated potato. The Solanum section Petota comprises tuber-bearing species that are potential donors of new disease resistance genes. The aim of this study was to explore Solanum section Petota for resistance genes and generate a widely accessible resource that is useful for studying and implementing disease resistance in potato. Description The SolRgene database contains data on resistance to P. infestans and presence of R genes and R gene homologues in Solanum section Petota. We have explored Solanum section Petota for resistance to late blight in high throughput disease tests under various laboratory conditions and in field trials. From resistant wild germplasm segregating populations were generated and assessed for the presence of resistance genes. All these data have been entered into the SolRgene .
