Hibiscus cannabinus, Host-status, Host-sensitivity, Root-knot nematode, Meloidogyne incognita.

Kenaf (Hibiscus cannabinus L.) is being investigated as an alternative industrial crop for inclusion in crop rotation programmes for the management of various plant parasitic nematodes. In Nigeria, cropping patterns and cultural practices vary from one area to another, thereby creating a great diversity in the combinations of nematodes species present and in the problems they cause. Root-knot nematodes, Meloidogyne incognita is the most serious potential problem to kenaf production. It was therefore necessary to determine if kenaf can be included in the cropping systems of resource poor farmers in areas where root-knot nematodes are problematic. The host-status and host-sensitivity of kenaf cultivars Ifeken 100, Ifeken 400, Cuba 108 and Tianung-1 to the root-knot nematode (M. incognita) were tested under greenhouse conditions. A split-plot design experiment with five replications was designed, where the main plot factors comprised with or without nematodes and the sub-plot factors are four kenaf cultivars. Twelve weeks after initiating treatments, the reproductive factors of M. incognita on kenaf cultivars were greater than one, without the cultivars suffering damage from the nematode infection. Results of the study show that the four cultivars were tolerant to M. incognita. Therefore these cultivars are not suitable for use in crop rotation programmes in the management of M. incognita since they would increase nematode build-up for subsequent susceptible crops.
