During the 2002 strawberry season, 21 varieties and new selections
were evaluated for postharvest berry quality. In collaboration with
Pam Fisher (OMAFRA), berries were harvested three times from four
farms in Southwestern Ontario. The results are presented in the following
two tables. Overall, 'Evangeline', 'L'Acadie', 'L'Authentique Orléans',
'Mira', 'St-Pierre', and 'Yamaska' had the most favorable postharvest
quality characteristics, whereas 'Kent', 'Sable', and 'Winona' had
the least favorable.
