Passion Fruit (Passiflora spp.) species as sources of resistance to soil phytopathogens Fusarium solani and Fusarium oxysporum f. sp. Passiflorae complex

Abstract The stem rot and fusarium vascular wilt are among the main factors most limiting passion fruit cultivation in State of Mato Grosso. This study aimed to evaluate resistance / susceptibility genus Passiflora species soil pathogens from different biomes Grosso (Cerrado, Pantanal Amazon). part I evaluated response P. edulis Sims, foetida, nitida quadrangularis on eight isolates F. solani. In II was genotypes mucronata, morifolia three oxysporum f. sp. passiflorae. experimental design randomized blocks factorial arrangement (genotypes x isolates). statistical analysis used for both steps were variance analyses by F test grouping averages Scott-Knott (P =0.05). Among solani found that FS8A FS3P more aggressive, indicating genetic variability isolates. resistant pathogen nitidaand foetida. passiflorae there no significant difference aggressive levels, mucronata Fusarium. Thus nitida, foetida mucronatacan be indicated as a source improvement commercial passionfruit programs.
