Characteristics of Yamaska
- Very late season
- Good eating qualities
- Good tolerance of powdery mildew and Botrytis
Yamaska has a very late and concentrated cropping season, fruiting 10-12 days after Elsanta.
Yamaska produces very large, dark red, glossy fruit. Flesh is dark throughout and fairly firm. The fresh fruit stores well for up to 5 days at room temperature.
Yamaska produces similar yields to the cultivars Joliette, Oka, Kent, Glooscap, Chambly and Bounty.
Plants are vigorous and produce 2-5 inflorescences each. Performance is good on both light and heavy soil types. Some of the flowers are male sterile, the use of pollinator varieties such as Alice or Florence may be needed to improve fruit yields.
Yamaska has good tolerance to powdery mildew (Podosphaera aphanis). Plants are moderately susceptible to the six North American Eastern races of red core (Phytophthora fragariae). Semi-resistant to leaf scorch, leaf blight and leaf spot has been observed. Good tolerance to grey mould (Botrytis cinerea) fruit rot was noted in trial evaluations.
Use of the Variety
Yamaska is recommended in areas where the climate is similar to that in the strawberry production areas of Quebec, Canada. It is useful where there is a need to extend the strawberry season.
