CURRENTLY THERE IS NO PLANT MATERIAL AVAILABLE
Parentage / Origin
Cascade Dawn was selected in 1991 by Dr Pat Moore from a cross of
WSU 991 and WSU 608 made at the Washington State University (WSU)
Puyallup Research and Extension Center, and evaluated as WSU 1068.
Season
In trials in the Pacific Northwest (PNW) of the USA, the midpoint
of harvest for Cascade Dawn was 10 days earlier than Meeker and
Tulameen.
Plant Characteristics
Cascade Dawn is very vigorous, produc¬ing more and longer canes
than either Malahat or Willamette. The basal portions of young canes
<30 cm tall have 20 to 40 spines per cm of cane.
Fruiting Characteristics
Fruit of Cascade Dawn are large, similar in size to Tulameen,
long conic in shape and glossy. The berries are firm and have an
excellent fresh flavour, with a good shelf life. In trials on sites
in the PNW with no obvious problems with root rot (Phytophthora
fragariae var. rubi), Cascade Dawn has produced similar yields to
Tulameen (Table 1). However, on sites with significant root rot
infection Cascade Dawn has produced significantly higher yields
(Table 2).

obvious problems with root rot.

Pest & Disease Resistance
Cascade Dawn is susceptible to the large raspberry aphid (Amphorophora
agathonica), the vector for the mosaic virus complex, but may be
resistant to pollen transmission of RBDV. In unsprayed plots, the
canes had a moderate incidence of spur blight (Didymella appanala),
somewhat more than Cascade Delight. In the PNW Cascade Dawn has been
planted in areas with high levels of root rot (Phytophthora
fragariae var. rubi) and has survived well, and had good yields.
Cascade Dawn is more root rot tolerant than Tulameen.
Potential Uses
Cascade Dawn has been noted for high yields of large, early season
fruit with excellent fresh flavour. The fruit is long conic in shape
and glossy. The fruit of Cascade Dawn does not release easily from
the receptacle until almost fully ripe and does not appear to be
suited for machine harvesting. It has a moderate level of root rot
tolerance and may be resistant to raspberry bushy dwarf virus.
Cascade Dawn is recom¬mended for fresh market uses.
