Resumen
The reactions of nine new synthetic diploid banana hybrids and their parental clones to Helicotylenchus multicinctus were studied in field trials. H-201, H-02-08, Anaikomban, Ambalakadali, Pisang Lilin and Eraichivazhai were resistant, whilst the hybrids H-204, H-211, H-02-11, H-02-12, H-59, H-65 and H-110 were moderately resistant. Among the resistant hybrids, H-02-08 produced significantly higher bunch weights than their parents. H-203, H-205, H-208 and H-66 were susceptible and H-02-01 and H-89 were highly susceptible to the nematode. The resistant clone H-02-08 had an enhanced reducing sugar content and H-201 and Pisang Lilin had enhanced contents of orthodihydric phenol and activities of phenylalanine ammonia lyase.
