Screening verschiedener Leguminosenakzessionen auf ihre Anfälligkeit gegen wichtige Wurzelpathogene

Summary

Leguminous species could provide multiple beneficial services to agroecosystems when grown as cover crops (CC) and/or living mulch species (LM) in rotations with cereals. However, these benefits can only become effective if the pathological risks are thoroughly assessed and solutions for potential problems identified. In order to assess suitability for inclusion of novel leguminous LM and CC species into the rotations, a total of 62 accessions were screened under controlled conditions for their susceptibility/resistance to major legume root infecting pathogens. Majority of tested plant accessions were highly susceptible to Fusarium avenaceum, and low to moderately susceptible to F. oxysporum and F. solani. Peyronelaea pinodella and Didymella pinodes most severely affected Lathyrus accessions, otherwise infections were low.
