Host plant response of Fusarium wilt resistant Musa genotypes to Radopholus similis and Pratylenchus coffeae

Ten Musa genotypes which were accepted by the International Musa Testing Pr ogramme (IMTP) to be resistant or moderately resistant to Fusarium wilt cau sed by Fusarium oxysporum f. sp. cubense, and three Fusarium wilt susceptib le cultivars, were evaluated on their resistance to Radopholus similis and Pratylenchus coffeae and their nematode host plant response compared with t he susceptible cultivar `Grande Naine'. In vitro propagated plantlets were transferred to the greenhouse in loamy sand in pots and inoculated with app roximately 1000 nematodes at 4 weeks after planting. Reproduction of R. sim ilis and P. coffeae in the roots was determined at respectively 8 and 10 we eks after inoculation. The `Pisang Jari Buaya' accessions ITC 0312 and ITC 0690, and `Yangambi km5' were resistant to R. similis. `Pisang Lilin', `Blu ggoe', `Saba', `Gros Michel', `Williams', `GCTCV 215', `GCTCV 119', `FHIA-0 1', `PA 03.22', `PA 03.44' were as susceptible to R. similis as `Grande Nai ne'. None of the 14 genotypes evaluated were resistant to P. coffeae.
