Field and shadehouse studies were carried out in Cameroon to compare the susceptibility to Radopholus similis of the \"Yangambi km5\" banana cultivar to that of other triploid Musa clones and also to evaluate its susceptibility to Pratylenchus goodeyi. Results of field trials have shown that populations of R. similis recovered from \"Yangambi km5\" every 2 months over a 2-year period were significantly lower than those from the other cultivars. A shadehouse experiment showed that different inoculum levels did not have any significant effect on the susceptibility of \"Yangambi km5\" to R. similis. Population levels of recovered 6 weeks after inoculation of \"Yangambi km5\" with 1000 and 10000 R. similis did not differ significantly from populations recovered on \"Yangambi km5\" inoculated with 100 R. similis. In contrast, the number of R. similis recovered from \"French Sombre\" (Musa MB Plantain sub-group) increased significantly with the inoculum level. The rate of development of R. similis on \"Yangambi km5\" was slower than that on \"French Sombre\". \"Yangambi km5\" was also found to be less susceptible to P. goodeyi than \"French Sombre\".
