Working Group "Genome Analysis and Application of Markers"
The focus of the working group was on the genetic analysis of agronomically important traits in rapeseed and faba bean. As a prerequisite for this, molecular markers and genetic maps were developed. Furthermore, linkage disequilibrium was analysed in adequate populations and the synteny between rapeseed and Arabidopsis as well as between faba bean, barrel medick and chickpea, respectively, was studied. On this basis, QTL (quantitative trait loci) for important yield related and quality traits were mapped and phenotypically characterized by interval and association mapping or in sets of intervarietal substitution lines. In addition, the genetic architecture of traits was also studied by analysing allelic diversity in relevant candidate genes by comparative sequencing followed by testing the observed allelic contrasts for possible phenotypic effects on the respective traits.

The working group was established in 1990 and research was conducted until 2022. Selected activities and teaching is ongoing.
Since 1990, the following PhD theses were completed in the working group:
