Evaluation of genetic resources to enhancement of tolerance to biotic stress in Rhododendron simsii
Project
Project code: JKI-ZGO-08-1180
Contract period: 01.09.2006
- 30.09.2010
Purpose of research: Basic research
Rhododendron simsii (potted azalea) is originated in China. Over the last decade, this species did not play an important role in plant breeding and breeding research in Germany.More than 1000 wild species within different sections belong to the genus Rhododendron. Most of them are originated in Asia. They are a potential source of enhancement of resistance in cultivated Rhododendron. Therefore, a complex of methods for the use of genetic resources for enhancemant of resistance in Rhododendron simsii will be established. In the first part of the project, characteristics of wild and cultivated Rhododendron will be evaluated with the focus on resistance against fungal infections.The second part of the project contains investigations of breeding system to explore and overcome interspecific and intergeneric incompatibility. Hereby, the aim is to produce new sexual hybrids with enhanced resistance.Moreover, possibilities of enhancement of genetic variability in Rhododendron at the somatic level are investigated (site-directed mutagenesis). The results of the project will be useful for evaluation of genetic resources in Rhododendron simsii and for enhancement of resistance.
