Abstract

Twenty four elite banana hybrids, six diploids (AA and AB), five triploids (AAA and AAB), ten tetraploids (AABB) and three pentaploids (AAABB) were screened under pot culture conditions for their reaction to lesion nematode, Pratylenchus coffeae. Among them the banana hybrids, H 516 and H 531 were rated resistant, while, H 511, H 534, H 537, H 571, H 572 and H 589 were rated tolerant to P. coffeae. The remaining accessions were rated as susceptible. Peroxidase, polyphenol oxidase, and phenylalanine ammonia lyase enzyme activities and total phenol contents in roots were higher in H 531 and H 516 than other hybrids.
