2002 Postharvest Quality Evaluations
of Strawberry Varieties
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.
