Julia is a summer fruiting, variety, which has produced high yields of
large, good quality fruit. It was released as a replacement for Glen
Clova and Malling Admiral with several advantages for growers over
these varieties.
Parentage / Origin
Raised from a cross, made in 1976 by Victoria Knight, between an
East Malling selection and a sister seedling of Glen Prosen. Julia,
formerly 4301/8 was selected initially in 1979 because of its fruit
quality, yield potential and above average shelf life.
Field & Fruit Characteristics
From 1986-88 Julia out-yielded Glen Clova and Leo by 36% and 73%
respectively. It also has a greater average berry weight, which could
lead to a slight reduction in picking costs. The well-flavoured fruit
is large, a good shape, easily plugged, medium red, slightly dull and
moderately firm.
Processing Quality
Canned and frozen samples were a better colour, texture and flavour
than Glen Clova. Julia produced good-flavoured jam with bold seeds.
Season
In trials both the first and 50% pick dates were approximately 7
and 14 days later than Glen Moy and Glen Clova respectively and 10-12
days earlier than Leo.
Plant Characteristics
A summer-fruiting type, Julia produces a moderate number of long,
fairly erect canes. The long laterals tend to droop under the weight
of fruit, but they are well attached and the fruit is well presented
to the pickers. The canes are moderately spiny.
Pest & Disease Resistance
Julia is resistant to strains 1 - 4 of the aphid virus vector
Amphorophora idaei. Resistant to cane Botrytis, spur blight (Didymella
applanata) and cane spot (Elsinoe veneta). Moderately resistant to
cane blight (Leptosphaeria coniothyrium). Susceptible to raspberry
bushy dwarf virus and Phytophthora root rot (P. fragariae var. rubi).
Marketing
The use of the variety would be good for PYO and processing
markets. In Scotland Julia was easily machine harvested.
Accreditations
The raspberry breeding programme at East Malling is funded by
Department for the Environment Food and Rural Affairs (Defra)
together with East Malling Trust for Horticultural Research (EMTHR)
and The Horticultural Development Council
(HDC). The trialling of the new raspberry selections is funded by the
HDC and MEIOSIS
