| Two Fusarium oxysporum f. sp. lycopersici (Fol race 2 and Fol race 3) and two f. sp. radicis-lycopersici (Forl) isolates plus eight to ten monosporic descendants from each were identified through molecular analysis and pathogenicity tests using differential varieties under different thermal conditions. The results for molecular and pathogenicity test for Fol were variable and to some extent contradictory. The Fol race 3 isolate and its progeny were amplified by the primers SIX1 and SIX3b but, depending on the test temperatures, the parental plus two descendants lost virulence, and one isolate completely lost virulence in all the tests. The Fol race 2 isolate was amplified by the SIX1 primer, but two descendants were not. The monosporic isolates and the parentals did not show pathogenicity on plants. All Forl isolates and progenies were amplified by the Forl primer, but one of the parentals plus all of its descendants did not show pathogenicity on plants. In addition, temperatures influenced the pathogenicity tests, yielding different virulences for Fol, which was enhanced at higher temperatures, whereas on the contrary a lower temperature was preferable for Forl. | |
