Parentage
Octavia was derived from Glen Ample x EM 5928/114 (family 6512)
from a cross-made in 1992. The original seedling (6512/50) was
selected in 1996.
Fruit Quality
The fruit is large, of uniform size, firm, cohesive, blunt and
conic to round in shape. It is easily plugged and meaty with fairly
good colour and good flavour. The shelf life of Octavia is good,
generally better then Glen Ample and consistently much better than
Tulameen.

Mean fruit weight o Octavia was intermediate between that of Glen
Ample and Tulameen. The results reflect big differences between
seasons, largely due to the weather. The mean fruit weights are
generally more reliable than the yield figures when comparing
genotypes in the Breeder’s Stage 0 trials.
Yield
Octavia was picked from a single 10-plant un-replicated plot in the
Breeder’s stage 0 trials in 1999 and 2000. In 1999, which was an early
dry season Octavia produced similar yields to Tulameen. In 2000 new
plots of Glen Ample and Tulameen produced more fruit than an older
plot of Octavia.
Season
Octavia is a very late ripening summer fruiting type cropping
approximately 10 days after Glen Ample and Tulameen.

1999 was an early season while 2000 was toward average. In both
years Octavia was later then Glen Ample and Tulameen, with even
further season extension in 2000.
Plant Characteristics
Octavia has a reasonably good habit, it crops to the base of the
canes, ahs upright, rather leafy laterals and the fruit is slightly
clumped at the end of the lateral.
Pest and Disease resistance
Octavia is resistant to biotypes 1-4 of Amphorophora idaei. It is
moderately resistant to cane Botrytis and cane spot but moderately
susceptible to spur blight. It is susceptible to Raspberry Bushy Dwarf
Virus at East Malling but has not shown leaf yellows. In a glasshouse
test at East Malling, 2003, Octavia was susceptible to raspberry root
rot (Phytophthora fragaria var. rubi).
Horticultural Value
Octavia will extend the summer fruiting season beyond that of Glen
Ample and Tulameen and will produce fruit well into August. It will
provide more of an overlap with the currant primocane fruiting cv’s.
The fruit quality attributes of Octavia, especially its shelf life,
will suit the fresh market.
Accreditations
The breeding of this variety was jointly funded by the
Department for the Environment, Food and Rural Affairs (Defra),
MEIOSIS Ltd and the East Malling Trust for Horticultural Research.
