Yangambi km5 (Musa AAA, Ibota sub-group): a possible source of resistance to Radopholus similis and Pratylenchus goodeyi.

Abstract

Field and shadehouse studies were carried out in Cameroon to compare the susceptibility to R. similis of the Yangambi km5 banana cultivar to that of other triploid Musa clones and also to evaluate its susceptibility to P. 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 R. similis recovered 6 weeks after inoculation of Yangambi km5 inoculated with 100 R. similis. In contrast, the number of R. similis recovered from French Sombre (Musa AAB 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.
