A
screening
of
68
tomato
samples
in
detached
fruits
bio
-
assays
were
performed
to
select
tomato
forms
resistant
to
both
P
.
infestans
and
P
.
capsici
.
Fruits
were
inoculated
with
zoospore
suspension
in
concentration
6000
zoospores
per
ml
.
Our
results
indicate
differences
in
tomato
resistance
to
these
pathogens
