Inwertsetzung wilder Verwandter der Kartoffel zur Entwicklung von genetisch erweitertem Keimplasma mit verbesserter Resistenz gegen die Kraut- und Knollenfäule (Phytophthora infestans)
[Use of crop wild relatives for genetic enhancement of potato germplasm with improved resistance to late blight (Phytophthora infestans)]

Abstract: Potato is among the most important food crops worldwide. Production of potatoes is threatened by late blight ( Phytophthora infestans ), a pathogen which constrains intensive chemical plant protection every season. Use of race-specific resistance genes from the primary genepool is no solution since the genetically adaptive pathogen quickly overcomes this type of resistance. A more sustainable approach appears to be using wild Solanum species from the secondary genepool as a genetic resource of quantitative resistance in potato breeding. Genetic enhancement of potato germplasm via introgressive pre-breeding is a time-consuming process which requires continuouscommitment. Results obtained from the potato pre-breedingprogramme at the Julius Kühn-Institut (JKI) demonstrate that it is feasible to combine high degrees of quantitative late-blight resistance with earlier maturation and acceptable quality characters.
