AbstractThirty-seven cultivars of cauliflower (Brassica oleracea) were evaluated for resistance to Meloidogyne javanica and to the four races of M. incognita in greenhouse pots. Most cultivars were susceptible to both species but some showed race-specific or species-specific resistance. Three cultivars were resistant to race 1, five were resistant to race 2, two were resistant to race 3, and three were resistant to race 4 of M. incognita. 'Pusa Snow Ball' and '74-6C' were tolerant to M. incognita race 4. Cauliflower cv. 74-6C was resistant and cv. Superial Maghi was immune to M. javanica. A single cultivar, Dania, was immune to M. javanica and to all races of M. incognita.
