Lavender (
Lavandula
spp.), a valuable essential oil plant in Lamiaceae (Mints) family, has an important place in aromatic and medicinal plants. Root-knot nematodes (
Meloidogyne
spp.) are important soil-borne pathogens that cause significant yield and quality losses in lavender cultivation areas. However, there are limited studies on the resistance of lavender cultivars to root-knot nematodes. The aim of the study was to determine the reaction of lavender (
Lavandula angustifolia
Mill.) and lavandin (
Lavandula x intermedia
Emeric ex Loisel.) cultivars to
Meloidogyne incognita
and
M. arenaria
isolates. This study was conducted with commercially traded
Lavandula;
Raya, Hebar, Imperial Gem, Munstead, Giant Hidcote cultivars belonging to lavender group and Silver and Grosso cultivars of lavandin group under the controlled conditions. All
Lavandula
cultivars were inoculated with second-stage juveniles (J2s) of S6 isolate of
M. incognita
and Çr-1 isolate of
M. arenaria
. The cultivar Giant Hidcote in the lavender group and Silver cultivar in the lavandin group were found resistant against both
Meloidogyne
species based on the gall and egg mass indices. Other tested cultivars were found susceptible to
M. incognita
and
M. arenaria
. These results could be useful in lavender and lavandin breeding programmes and in the integrated root-knot nematode management.
