✦ Synopsis

The burrowing nematode (Radopholus similis) is one of the major nematode species attacking banana and plantains . Sources of resistance to this nematode were found and studies were made of the resistance mechanisms involved . Relatively greater numbers of preformed phenolic cells were found in roots of the resistant and intermediately resistant cultivars Yangambi km5 and Gros Michel than others . However, in another resistant cultivar, Pisang Jari Buaya, fewer phenolic cells were found, but this clone had high numbers of cells with lignified walls suggesting a different mechanism of resistance . An interesting correlation was found between level of susceptibility to R. similis and root dry matter. A possible role of lignin in resistance to R. similis in Musa is also indicated .
