Özet:

Carnation is one of the most crucial cut flowers in Turkey. Root-knot nematodes (RKNs) cause significant damage on carnation production and quality. Therefore, determination of response of carnation varieties to RKNs is required for management practices. In this study, four carnation cultivars, Turbo, Betsy, Nirvana and Glaciar, were inoculated with second stage juveniles (J2s) of Meloidogyne incognita, M. javanica and M. arenaria under controlled conditions. Meloidogyne incognita, M. javanica and M. arenaria did not reproduce on Turbo variety. Therefore, Turbo variety was found to be resistant to these nematodes. Nirvana variety was moderately resistant to M. incognita and M. javanica, but highly resistant to M. arenaria. Betsy and Glaciar varieties were susceptible to M. incognita, M. javanica and M. arenaria. Results showed that the response of carnations was different based on root knot nematodes. Determining resistant carnation varieties could be an advantage for the control of RKNs. Resistant carnations could be used to control the RKNs and develop new carnation varieties.
