Parentage

Yamaska is a progeny from a cross between two late season cultivars, “Pandora” and “Bogota”, made in 1989.

Fruit Quality

Yamaska produces very large, dark red, glossy fruit. Flesh is dark throughout and fairly firm. Fresh fruit store well for up to 5 days at room temperature.

Yield & Fruit Size

Yamaska produces similar yields to the cultivars “Joliette, Oka, Kent, Glooscap, Chambly and Bounty. Yamaska has the most concentrated crop compared to the other cultivars noted above.

Plant Characteristics

Plants are vigorous and produce 2-5 inflorescences each. They perform very well in sandy soil and are also adapted to growing compact or heavy soil. The variety is male sterile and required planting with pollinator varieties e.g. Alice, Florence.

Disease Resistance

No symptoms of powdery mildew (Sphaerotheca macularis) were noted since observations began in 1990. Plants are moderately susceptible to the six North American Eastern races of red core (Phytophthora fragariae) based on the presence of red-stele and oospores in the root segments. Semi-resistant to leaf scorch, leaf blight and leaf spot. No signs of grey mould (Botrytis cinerea) fruit rot were observed during the course of evaluation.

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.
