Fifty-two accessions representing 11 wild Cicer spp. were screened for resistance to races 0 and 5 of Fusarium oxysporum f. sp. ciceris from Andalucia, southern Spain, in pot-culture inoculations in growth chambers, and 47 accessions were tested for resistance to race 5 in inoculated field microplots in Cordoba, Spain. Resistance to F. o. ciceris race 5 was identified in accessions of Cicer bijugum, C. cuneatum, and C. judaicum, and resistance to race 0 was found in accessions of C. bijugum, C. canariense, C. chorassanicum, C. cuneatum, C. judaicum, and C. pinnatifidum. Isolations from asymptomatic plants of inoculated Cicer spp. indicated that the resistant reaction to races 0 and 5 occurred with or without systemic colonization of aerial tissues by the pathogen. No transmission of F. o. ciceris races 0 and 5 was detected in seed harvested from plants of eight Cicer spp. used in the artificial inoculation or microplot studies. |
