Assessment of genetic resources of the IPK Potato Genebank for foliage and tuber resistance to Phytophthora infestans
Project
Project code: JKI-ZL-08-3165
Contract period: 01.01.2008
- 31.12.2019
Purpose of research: Applied research
Characterisation of resistance to tuber and foliage blight in genetic resources is carried out within a cooperation program between the IPK Genebank and JKI to take the advantage of synergistic effects. Hereby the IPK Genebank is responsible for plant propagation and sampling. JKI carries out resistance tests. The data are required to develop knowledge if and to which extent the available samples are possible sources for resistance and which accessions can be useful to select healthy and resistant plants in future by methods of breeding research. In addition to the research plan of BMELV the project represents a contribution for the national program 'plant genetic resources', step 5.3.2: Expansion of characterization, prior evaluation and development of core collections and meets the requirements for the specific transfer into the field of action 5.8.2
'Improvement of research for resistance of cultivated crops against pests' of the reduction program chemical plant protection.'
Each year 22 Solanum-species with 52 accessions and 260 genotypes from the Groß Lüsewitz wild potato assortment are tested for their foliage- and tuber-blight reaction. Evaluation data of the different accessions prove a high variability between different wild species and within the same species. About 20 genotypes containing a high level of resistance against Phytophthora are selected each year. The aim is its further characterisation and utilisation in crossing programmes to incorporate resistance genes against foliage- and tuber-blight into the cultivated potato.
