| Abstract:
Several species of plant parasitic nematodes attack bananas in the subtropics causing economic damage to the crop. Losses during the production phase appear to be variable and depend mainly on the Musa cultivar, agronomic practices, interaction with rhizosphere organisms and agro-ecological region. The lesion nematode Pratylenchus goodeyi is important and widespread in subtropical regions of the world, especially in highland Africa and in the Canary Islands. Management practices have relied mainly on the use of nematicides for bananas produced for export markets. A recent effort oriented towards selecting resistant plant material has been made in the last four years. Several supposed known sources of resistance, tested against a P. goodeyi isolate from Tenerife have shown different levels of susceptibility, although the accession Yangambi Km 5 proved to be a poor host for P. goodeyi. Resistance has been detected in Africa, but not in the Canary Islands suggesting differences in pathogenicity among populations of this nematode pest. | |
