This research
aimed to determine the relationship between the color of the
pigment produced by isolates of F. verticilliodes and virulence
in maize seedlings. Symptomatic and asymptomatic corn cobs
were collected in Veracruz State, Mexico during the springsummer
cycle of 2008. The experiment was analyzed using an
experimental design in split plots with a double division, under
greenhouse conditions during two crop cycles, fall-winter of
2008 and spring-summer of 2009, in the Postgraduate College
Campus Montecillo, Mexico State. The pigmentation of the
isolates obtained from symptomatic seeds with mycelium was
more intense with a purple color, and the white mycelium
isolates showed a more homogeneous color. Isolates from
asymptomatic seeds had a tenuous violet coloration, and from
white to cream coloration of mycelium. It was observed that
isolates from symptomatic and asymptomatic seeds were
pathogenic; the purple isolations from symptomatic seeds
were more virulent than the white isolate, opposite to what
happened with the isolation from asymptomatic seeds, in
which the white mycelium was more virulent.
