To select resistant oil seed crops against two species of root-knot nematodes, M. incognita and M. arenaria, 10 cultivars of sesame (Sesamum indicum) and 10 cultivars of perilla (Perilla frutescens var. japonica) were screened in greenhouse pot test. All sesame cultivars tested were resistant to M. incognita but susceptible to M. arenaria. While, perilla was resistant to both Meloidogyne species. Therefore, perilla cultivars could be used as rotation crops in greenhouses infested with both M. incognita and M. arenaria. But, sesame cultivars only can be used as a rotation crops in greenhouses infested with M. incognita but not for M. arenaria.
