Collaborative project: Development of a screening method for resistance of radish against new bacterial leaf spot diseases (Pseudomonas spp.) as basis for breeding resistant varieties. Subproject 2
Project
Project code: 2814505810
Contract period: 01.02.2011
- 31.01.2014
Budget: 119,024 Euro
Purpose of research: Experimental development
Since a few years radish field crops suffer from leaf spot diseases by different Pseudomonas bacteria, especially during extreme weather conditions such as heavy rainfall. One way of pathogen transmission may be via seed. Breeding for resistance seems to be the only way of disease control. So far resistance against pseudomonads among current radish varieties is unknown. Breeding for resistance will be possible on the basis of a suitable screening test. Additionally a testing procedure for surveying seed contamination will be developed. During a period of 3 years, a screening test will be developed to investigate disease development and defence reactions on detached radish leaves. Thus the vigour of the tested individuals will not be affected. In order to compare the results in this procedure with artificial inoculation to open field conditions, a set of representative cultivars and accessions will be grown under natural infection conditions. Then the screening test will be implemented in the breeding stations. Additionally a test for surveying seed contamination will be developed and implemented.
