Collaborative project: Development of a resistance breeding method for the host pathogen system potato/ Rhizoctonia solani and the development of an application strategy for a fungal antagonist for the reduction of the soilborne and tuberborne inoculums - Subproject 2
Project
Project code: 2814700911
Contract period: 01.02.2013
- 30.06.2016
Budget: 109,589 Euro
Purpose of research: Applied research
Quality deficiencies of potato tubers caused by Rhizoctonia solani are one of the main reasons for refusal of production charges by the processing industry. The cultivation of resistant cultivars is an efficient control strategy. Hence, the main goal of the project was to establish a test method which does allow the reliable characterization of the resistance level in potato cultivars against R. solani. Results of field experiments confirm that quantitative differences occur in the resistance of potato cultivars against the pathogen. Comparative molecular and physiological analyses using a moderately and a highly resistant potato cultivar revealed a relationship between the constitutive expression level of defense related genes in potato tissue and the level of distinct secondary metabolites to the field resistance to black scurf disease. However, these relationships have to be verified in further comparative analyses using more cultivars differing in their resistance level to R. solani.
