Similar season to Tulameen.
The fruit of Chemainus resemble Tulameen, being long and conical shaped with fine drupelets. Berries are firm, shiny and medium to dark red in colour. The fruit is of high quality with good firmness. The firmness, colour and attractive appearance of Chemainus fruit make it highly desirable for individual quick freezing (IQF).
Chemainus crops very heavily. It is a multi-purpose cultivar suitable for both processing and fresh market sales, it is well suited to mechanical harvesting.
Chemainus is a highly vigorous cultivar with an upright habit. Spines are dense on the lower 30 cm of the canes but relatively sparse up the canes, which is similar to those on Tulameen. Because of its early bud break, Chemainus shows some bud damage after sudden drops in temperature during mild winters. When winters are cold, it shows good winter hardness with little or no damage relative to other Pacific Northwest (PNW) cultivars.
Chemainus is resistant to the common biotype of Amphorophora agathonica Hottes, the North American aphid vector of the raspberry mosaic virus (RMV) complex. Although susceptible to RBDV, Chemainus does not express symptoms of yellow leaves and experiences a long delay before expression of crumbly fruit symptoms. Chemainus may exhibit some degree of field resistance to root rot caused by Phytophthora fragariae var. rubi. It has shown moderate susceptibility to spur blight (Didymella applanata), to cane Botrytis (Botrytis cinerea) and to anthracnose (Elsinoe veneta Burkh.), similar to its parent Tulameen.
