    Notes: Abstract Isolates ofMycosphaerella brassicicola, originating from various locations in Europe, differed in their virulence on a differential set of brassica cultivars, as measured by the number of lesions per leaf. Hypersensitivity and significant cultivar-isolate effects were observed, indicating a differential host-pathogen interaction. Although expression of resistance depends on plant development, the differential host-pathogen interaction was found in all plant stages tested. This is the first report on the existence of physiological specialization ofM. brassicicola.

    A screening test for Mycosphaerella brassicicola on Brassica oleracea (1992)

    Notes: Abstract A greenhouse screening method for resistance to ringspot (Mycosphaerella brassicicola) inBrassica oleracea is described. High infection levels were achieved by spraying young plants by mycelial inoculum enriched with 3% sucrose. The screening method was tested on three Brussels sprouts, three cabbage and three cauliflower cultivars, with known reactions to ringspot in the field. Resistance was expressed both in cotyledons and true leaves by a lower number of lesions than the susceptible control and/or by hypersensitive reactions. Results of the seedling tests reflected differences in resistance in the field. Under controlled conditions the new test can be applied year-round to young plants, thus accelerating selection procedures.

    Seedbed infection of white cabbage by Mycosphaerella brassicicola (1993)
    Springer
    European journal of plant pathology 99 (1993), S. 139-148

    Notes: Abstract Three cultivars of white cabbage with different levels of resistance toMycosphaerella brassicicola were tested for seedbed infection. Seedlings grown in seedbeds, to which infected plant debris was added as an inoculum, showed typical ring spot lesions on the cotyledons and first two leaves before seedlings reached the transplanting stage, whereas non-inoculated controls had few lesions only. Differences in levels of resistance between cultivars were present in seedlings grown under field conditions. Disease severity of transplants at the end of the season reflected disease severity of seedlings before transplanting in each cultivar. To lower the risk of a severe epidemic of ringspot at the end of the growing season, the seedbed should be protected from infection byM. brassicicola.
