摘要：

Resistance to Plasmodiophora brassicae Woron, the causal fungus of clubroot, was examined in an F-2 population of a cross between a clubroot-resistant kale (Brassica oleracea L. var, acephala) and a susceptible cauliflower (Brassica oleracea L. var. botrytis). QTL detection was performed with RAPD markers. Two resistance notations, carried out at different times after inoculation, were used. Three markers were associated with these two notations and three were specifically linked to only one notation. QTL analysis the existence of at least two genetic mechanisms implicated in the resistance phenomenon.
