Abstract : The coffee disease complex known as corky-root, composed of the root-knot nematode #Meloidogyne arabicida# and #Fusarium oxysporum#, causes serious damage to #Coffea arabica# in Costa Rica. Resistance to #Meloidogyne arabicida# alone and to the field population (#M. arabicida#, #M. exigua#, #F. oxysporum#) was evaluated under controlled and field conditions. The studied material consisted of subspontaneous-derived #C. arabica# accessions, #C. canephora# accessions, introgression lines derived from the interspecific Timor Hybrid (#C. arabica# x #C. canephora#) and F1 hybrids from crosses between subspontaneous-derived accessions and cultivars. Accessions resistant to #M. arabicida# and to the field population were identified at varying frequencies in the different groups of study materials. The results showed that resistance to corky-root is heritable and that genetic resistance to #M. arabicida# is an effective strategy against corky-root disease. By using #C. canephora# rootstocks, it was possible to substantially reduce mortality in the field and reduce by half the number of plants with corky-root symptoms. The results were used to define appropriate strategies for the sustainable management of coffee corky-root disease resistance. (Résumé d'auteur)
