’MATERIALS AND METHODS
Plant Material. The purple tomato breeding line V118 used in this
study was grown in the processing tomato breeding plots of the
University of Guelph Ridgetown Campus, on a Brookston silt loam soil
near Ridgetown, Ontario, Canada. This accession was a collection of one
of the authors (S.L.). Transplants were set in the field in May 2009, in
single rows, with 45 cm plant spacing within the row, and rows spaced
150 cm apart. The plots were maintained according to a standard
processing tomato production management system with the exception
that fungicides were not applied.
