Comparison of fitness parameters between the iprodione-induced mutants and the parental strains.

aG0 is the wild-type parent isolate, G20C is the 20th transfer generation produced on PDA medium without iprodione (control) and G20I is the 20th transfer generation produced on PDA supplemented with iprodione.bDaily radial growth rate between the 3rd and 4th day after inoculation.cSpore produced on PDA medium 14 days after inoculation.dSpore produced on tomato stem 7 days after inoculation.eData are means of two to three independent repetitions. For each isolate, means within a column followed by the same letter were not significantly different (ANOVA, α = 0.05; Newman–Keuls test).
