英语. 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-O208 produced significantly higher bunch weights than its 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 activity of phenylalanine ammonia lyase

H-201, H-02-08, Anaikomban, Ambalakadali, Pisang Lilin e Eraichivazhai sono risultati resistenti, mentre gli ibridi H-204, H-211, H-02-11, H-02-12, H-59, H-65 e H-110 erano moderatamente resistenti. Fra gli ibridi resistenti, H-O208 ha prodotto caschi di peso significativamente superiore rispetto ai suoi parentali. H-203, H-205, H-208 e H-66 erano suscettibili e H-02-01 and H-89 altamente suscettibili al nematode. Il clone resistente H-02-08 ha fatto riscontrare un contenuto aumentato di zuccheri riducenti e H-201 e Pisang Lilin presentavano un aumento del contenuto di fenolo ortodiidrico e dell'attività della fenilalanina ammoniaca liasi.]
