Cultural practices adopted to control
TYLCV epidemics must be combined with
use of tolerant or resistant tomato varieties
in severe open-air attacks (17,27). Unfortunately,
current breeding programs based
on resistance found in wild Lycopersicon
spp., mainly in L. chilense, are progressing
slowly, partially due to the lack of effective
means for accurate selection of resistant
plants (32,33). In other viral diseases affecting
tomato, marker-assisted selection
(MAS) provides a convenient and rapid
