Summary

Rotklee ist als essentielles Fruchtfolgeglied speziell im ökologischen Landbau unentbehrlich. Resistente Sorten wären im Falle einer Ausbreitung der Pilzkrankheit Anthracnose von zentraler Bedeutung.

Summary translation

Recently, there has been evidence both from testing sites and agriculturally used fields concerning the appearance of Colletotrichum trifolii Bain et Essary, causing Southern Anthracnose in red clover and red clover pasture stands. This disease is able to cause large losses in yield. The aim of this investigation was to evaluate all red clover cultivars listed in Germany (in 2009) with regard to their resistance against the pathogen. One foreign genotype ‘Starfire’, bred in the USA and known to be highly resistant to Southern Anthracnose, was also incorporated into this research. A ranking of the cultivars could be generated based on a test for resistance performed in the greenhouse. The resistance of the cultivars was expressed as a percentage of plant survival seven weeks after inoculation. Results showed a wide range in quantitative resistance characteristics towards Colletotrichum trifolii from 29 to 87% survival. Hence the evaluated genotypes can be classified into resistant to susceptible forms. Another important finding was that among the screened varieties diploid cultivars overall seemed to be more resistant than tetraploid genotypes.
Diese Ergebnisse wurden im Rahmen des vom BÖLN finanzierten Forschungsvorhabens FKZ 2806OE161 ermittelt.
