Assessment of the tolerance or resistance of potato cultivars and breeding lines to late blight (Phytophthora infestans)
Project
Project code: JKI-ZL-08-0070
Contract period: 01.04.2010
- 31.12.2017
Purpose of research: Inventory & Assessment
The activities are embedded in the official VCU testing by the Bundessortenamt and comprise the assessment of late-blight resistance of released cultivars and new breeding clones accepted for official testing. The resistance tests are carried out in field trials with four replications after artificial inoculation with a highly virulent field isolate of Phytophthora infestans, carrying virulence for the major genes R1 - R11. Disease severity is evaluated at least two times a week until maturity by recording the percentage of attacked area of potato tops within each plot. Multiple readings allow the calculation of a disease progress curve for each clone tested.
