Fusarium oxysporum f. sp. ciceris, and the root-knot nematode Meloidogyne artiellia, coinfect chickpea crops in several countries of the Mediterranean Basin. The influence of root infection by M. artiellia on the reactions of chickpea genotypes with different reaction to infection with F. oxysporum f. sp. ciceris races 0, 1A, and 2 was investigated under controlled environmental conditions. Results demonstrated that co-infection of chickpea genotypes resistant to specific fungal races by M. artiellia did not influence the Fusarium wilt reaction of the plant, irrespective of the F. oxysporum f. sp. ciceris race assayed. However, in some of the assayed combinations, coinfection by both pathogens significantly affected the level of colonization by the fungus or reproduction of the nematode in the root system. Thus, coinfection of chickpea plants with Foc-0 and M. artiellia significantly decreased the level of colonization of the root system by F. oxysporum f. sp. ciceris in genotypes 'CA 336.14.3.0' and 'PV 61', but not in 'ICC 14216 K' and 'UC 27'. Similarly, the nematode reproduction index was also significantly reduced by coinfection with Foc-0 in the four chickpea genotypes tested and inoculated with this race. Conversely, coinfection of chickpea plants with Foc-1A and M. artiellia significantly increased colonization of the root system by the fungus in all genotypes inoculated with this race, except for line BG 212. Altogether, we confirmed the complete resistance phenotype of 'UC 27' and 'ICC 14216 K' to Foc-0, and of 'ICC 14216 K' to Foc-1A and Foc-2, and demonstrated that this resistance was not modified by coinfection of the resistant plant with M. artiellia.
