    Abstract

    A sample of 22 accessions of Brassica oleracea were screened for their responses at the seedling stage to twelve isolates of the fungal pathogen Peronospora parasitica (downy mildew), and 14 accessions were screened for their responses at the seedling stage to nine isolates of Albugo candida (white blister). The results suggested that classic gene-for-gene interactions operate in the P. parasitica pathosystem whereas in the A. candida pathosystem the results could be explained either by a gene-for-gene model or an additive gene model. Interpretation of the results for both pathogens was complicated by the heterogeneous nature of the host plant accessions and differential lines are therefore being developed in a homogeneous genetic background to allow further investigation of these pathosystems to be carried out.
