Abstract:

The burrowing nematode, Radopholus similis is considered to be the most destructive nematode associated with banana growth worldwide. Cultural and chemical management alone cannot guarantee full control. An alternative is to develop new banana hybrids with resistance to burrowing nematode. The twenty four new synthetic banana hybrids were screened under artificially inoculated pot condition for their reaction and resistance mechanism against Radopholus similis. Five hybrids namely, H 912, H 914, H 916, H 926, H 943 were rated resistance to Radopholus similis based on the nematode multiplication, lowest root lesion and corm lesion index. The nematodes inoculated resistant hybrid H 916 had higher total phenols (567.21 μg/g) and orthodihydroxy phenols (2.77 μg/g) activities than the susceptible cultivars. The enzymes changes in root content of peroxidase (2.78-3.32 abs/min/g), polyphenol oxidase (0.086-0.113 abs/min/g) and phenylalanine ammonia lyase (23.28-30.12 nmol/min/ml) of the hybrids in defense mechanism in response to nematode invasion indicated higher activities in resistance plants viz-a-viz susceptible ones.
