摘要
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.
