A total of 33 carnation cultivars cultured in Korea were screened for
resistance to the southern root-knot nematode, Meloidogyne incognita.
Carnations were tested by either inoculating with 5,000 eggs or by tra
nsplanting into a mixture of bedding medium and soil infested with an
average of 435 second-stage juveniles/300 cm(3) soil. Cultivars, Desio
, Castelaro, Kappa, Rara, Izu Pink, Target, and Antalia were highly re
sistant to M. incognita. Twelve cultivars were moderately resistant, a
nd the remaining 14 cultivars were susceptible. These results were sim
ilar to those obtained when the cultivars were subjected to field popu
lations of the condition on a carnation farm.
