摘要

Seven Musa genotypes were examined for their host response to Radopholus similis in the first of two greenhouse experiments. Out of the seven Musa genotypes tested, Long Tavoy, Saba, Pisang Mas and Pora Pora were resistant to R. similis based on the final nematode population density. Marau expressed a partial resistance to R. similis. The host response of Kokopo was inconclusive and Gia Hui was susceptible to R. similis. The study confirmed other reports that tissue culture-derived plants of some Musa genotypes were probably susceptible to R. similis while sucker-derived plants of the same Musa genotypes were resistant. Yangambi km5 is a more reliable R. similis resistant reference cultivar than Pisang Jari Buaya. In the second experiment, eight Musa genotypes were examined for their host response to M. incognita. For the first time, Vudu Papau and Pisang Mas were identified as resistant to M. incognita based on the final nematode population density. It has become evident that Pisang Mas is a Musa genotype with combined resistance to both R. similis and M. incognita. This is the first time that a Musa genotype has been found as resistant to these two major banana root pathogens.
