✦ Synopsis

About 1000 Brassica oleracea accessions were evaluated in glasshouse tests for response to Plasmodiophora brassicae (clubroot) . Resistance was confirmed in some north and west European kales and cabbage . A new source of resistance in cabbage, from Eire, is reported . Most other accessions were highly susceptible but lower levels of susceptibility were observed in open pollinated Brussels sprouts and forms of south European cabbage, cauliflower and broccoli . Modern breeding (as in the production of hybrid cultivars) appears to have resulted in increased susceptibility in several crop types . The implications of these results for the exploitation of germplasm are discussed .
