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. Some of the flowers are male sterile and the
use of pollinator varieties e.g. Alice, Florence might be needed to
improve yield.
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. |
