EXPLANATION
Biological Control, Bioagents , Host Resistan
- Nematode Resistance in Banana Cultivars:
- Cultivar 'Yangambi Km5' (AAA, Ibota subgroup): A landmark diploid/triploid banana cultivar widely renowned for high genetic resistance against the destructive burrowing nematode Radopholus similis through rapid suberin and lignin deposition in cortical root cells.
- Susceptibility to Pratylenchus: While 'Yangambi Km5' resists Radopholus similis, it is susceptible and does not confer resistance to the lesion nematode Pratylenchus goodeyi.
- Conclusion: Statement (I) is incorrect but Statement (II) is correct (Option 4).
