Since there is no effective and economically viable control available, development of resistant or at least tolerant cultivars are in demand. A number of procedures have been used for the initial selection of plant genotypes resistant to various fungal pathogens by means of a fungal culture filtrate or purified toxin. In this study, seeds and in vitro-grown plantlets of passion fruit were screened with different concentrations of either Fusarium oxysporum f. sp. passiflorae (FOP) culture filtrate (0, 20, 30, 40 or 50%, v/v) or fusaric acid (0.10, 0.20, 0.30 or 0.40 mM) supplemented in Murashige and Skoog (MS) basal media. Subsequently, selected plants were inoculated with a conidial suspension of FOP to assess correlation between in vivo and in vitro responses. In vitro sensitivity to the selective agents and the resistance response to the pathogen were also compared. Root growth was markedly influenced by FA, culture filtrate, and conidial suspension culture treatments. Observations indicated that roots were primary targets for attack by F. oxysporum. Successful in vitro selection of resistant genotypes by both FA and culture filtrate treatments suggested that this strategy was viable for accelerating breeding of passion fruit for resistance to the Fusarium vascular wilt.  aAgronomic traits  aFungi  aGenotype  aIn vitro culture  aPlant diseases and disorders  aCaracterísticas Agronômicas  aCultura in vitro  aDoença de planta  aFungo  aFusariose  aGenótipo  aMaracujá Peroba  aPassiflora edulis flavicarpa  aSeleção genótipa  aVariedade resistente  aCultivo in vitro  aEnfermedades y desórdenes de las plantas  aFusariosis  aFusarium oxysporum f sp passiflorae  aMaracujá amarelo  aMaracuyá amarillo  aPassiflora edulis f flavicarpa  aYellow passion fruit1 aOTONI, W.
