SUMMARY A new race of Plasmodiophora brassicae with a range of pathogenicity to B. napus different from that of previously known races has been isolated. The race is designated N4. Genetic studies have shown that resistance to N4 is governed by a major gene with resistance dominant to susceptibility.
